Description

本発明は骨材業界で年中不足気味の砂を製造するために砕石３０ミリ以下と砂利３０ミリ以下（以後原石と呼びます）を破砕して破砕砂の尖角を潰して粒形の良い川砂に等しい砂を製造するドラム式川砂製造装置に関するものであります。  In the aggregate industry, in order to produce sand that is deficient throughout the year, the crushed stone is less than 30 mm and gravel is less than 30 mm (hereinafter referred to as rough stone) to crush the cusp of the crushed sand and to have good shape It relates to drum type river sand production equipment that produces sand equal to river sand.

昭和３０年代までは土木建築用コンクリートに使用する骨材としての砂、砂利は主として河川から採取されたものが使用されていた。しかし昭和４０年頃から河川の砂利の採取規制が始まり、その後も次第に採取規制が厳しくなり現在では河川の砂利の採取が禁止になっています。
一方建設業界においては砂、砂利の需要が益々増大してきた。このため、河川以外の砂利採取地として、河川周辺の農地、山、海等から砂利、砂が採取されている。現在では山の砕石等が主に採取されている。
砂利の不足は山の砕石で補われていますが砂の不足は補うものがなく主に中国から輸入していますし、骨材業界では砕石１０ミリ以下及びビリ砂利１０ミリ以下を細粒破砕機などで人工的に砂を製造しています。Until the 1950s, sand and gravel as aggregates used for concrete for civil engineering and construction were mainly collected from rivers. However, river gravel collection regulations began around 1965, and the collection regulations gradually became stricter thereafter, and river gravel collection is now prohibited.
On the other hand, in the construction industry, demand for sand and gravel has been increasing. For this reason, gravel and sand are collected from farmland, mountains, seas, etc. around the river as gravel collection sites other than rivers. At present, mountain crushed stones are mainly collected.
The shortage of gravel is compensated by crushed stones in the mountains, but the shortage of sand is not supplemented, but mainly imported from China. Manufacture sand artificially.

私も平成５年からビリ砂利（粒度５〜１０ｍｍ）を破砕して砂を造る破砕機の研究開発に取り組み、１０数年を要して新技術のスプリング付ジョークラッシャーの砂製造機を完成させました。特許第３９４２０３１号を取得し、販売中であります。製造された砂は粒形も良く申し分のない破砕機であります。
１日の生産量が２０トン〜３０トンと少ないのはジョークラッシャーの構造上の問題でありますので小規模の砂利プラントに適しています。
砂利採取業者の方々は１日１００トン位生産できる砂製造機を求めています。Since 1993, I have been working on research and development of a crusher for crushing billet gravel (grain size 5-10mm) to make sand, and in 10 years, I completed a new spring crusher-made jaw crusher sand making machine. It was. Obtained Japanese Patent No. 3942031 and is now on sale. The sand produced is a fine crusher with good particle shape.
The low daily production of 20 to 30 tons is a problem in the structure of the jaw crusher, so it is suitable for small gravel plants.
Gravel collectors are looking for sand making machines that can produce around 100 tons a day.

現在骨材業界では砂の製造機としては主に細粒破砕機のロッドミルが使用されています。
ロッドミルは円筒状の機械の中に太い鉄のロッド棒を５トン〜１０トン入れてそのロッドを回転させロッドが衝突している処へ原石と水を投入して破砕し砂を造る構造の破砕機であります。
排出される破砕粒子は振動篩の砂網で振り分けられ５ｍｍ以下は砂として回収され、それ以上は再度投入口へ戻されます。At present, the aggregate industry mainly uses the rod mill of fine grain crusher as the sand making machine.
A rod mill is a crushing structure in which a thick iron rod rod is put into a cylindrical machine, 5 to 10 tons, and the rod is rotated to throw rough stone and water into the place where the rod collides to crush and create sand. It is a machine.
Discharged crushed particles are distributed by a sand screen of a vibrating sieve, and 5mm or less is collected as sand, and the rest is returned to the inlet.

ロッドミルの運転稼動はロッド棒が磨耗して来ますと破砕効率が悪くなりますので１ヶ月に１〜２度細くなったロッド棒を取り出し新しく太いロッド棒を挿入して運転しています。
更に年に１回位の割合で回転胴の内張りも磨耗して来ますので取替える必要があります。When the rod mill is worn, the crushing efficiency deteriorates as the rod rod wears out. Therefore, the rod rod that has been thinned once or twice a month is taken out and a new thick rod rod is inserted.
Furthermore, the lining of the rotating drum will also be worn at a rate of about once a year, so it must be replaced.

又同じロッドミルでもロッド棒の代わりに鉄のボール６０ｍｍ前後を数トン入れて回転胴を回転させ中の鉄のボールが衝突、すりもみしている中へ原石１０ｍｍ以下と水とを投入して破砕し砂の粒子を製造する方法もあります。
この場合も鉄のボールが磨耗して来ますと破砕効率が悪くなりますので１ヶ月に１〜２回鉄のボールを追加投入する必要があります。Also, in the same rod mill, instead of the rod rod, insert several tons of iron balls around 60mm, rotate the rotating drum, and the iron balls in the middle collide and grind the raw stone 10mm or less and water. There is also a method to produce sand particles.
In this case as well, if the iron balls are worn, the crushing efficiency will deteriorate, so it is necessary to add additional iron balls once or twice a month.

消耗品としては〔０００５〕は回転胴内で鉄のロッド棒が衝突、すりへりを起こして原石を破砕しているので月に１〜２回のロッドの挿入が必要でありロッド棒の損耗が激しい又〔０００６〕も鉄のボールのすりもみ、すりへりで原石を破砕しているので月に１〜２回追加投入の必要がありますのでボールの損耗が激しい更に回転胴の内張りも磨耗で年１回位の割合で取替える必要があります。  [0005] As a consumable item, the rod rod of iron collides in the rotating drum, and the rough stone is crushed by crushing, so it is necessary to insert the rod once or twice a month, and the rod rod is heavily worn out. In addition, since [0006] grinds the iron balls and crushes the rough ore, it is necessary to add it once or twice a month, so the ball wears more severely. It is necessary to replace it at the rate of rank.

費用としては上述の〔０００７〕のロッド棒並びに鉄のボールの激しい損耗をお金で評価すれば、１トン１０万円近くする鉄のロッド棒並びに鉄のボールをすりへらしながら１トン２千円以下の砂を製造しています。こんな経済効率の悪い方法で砂を製造しています。更に回転胴の内張りの取替えにも多額の費用がかかります。
次に回転胴を回転するには重い重量のロッド棒並びに鉄のボール全部を回転させなければならないので駆動出力も大きくなり中クラスのロッドミルでも７５ＫＷ〜１５０ＫＷのモーターが使われています。動力は３，０００ボルトの電圧で運転していますので電力料金も高くつきます。
総合的に見て鉄の高い現在ではロッドミルは経済効率の悪い破砕機だと思います。しかし生コンプラントではどうしても砂が必要ですので現在全国的にロッドミルが使われています。As for the cost, if we evaluate the severe wear of the rod rod and iron ball of [0007] above with money, the iron rod rod and iron ball that cost nearly 100,000 yen per ton will be worn down to 2,000 yen per ton. Manufacturing sand. Sand is produced in such an economically inefficient way. In addition, it takes a lot of money to replace the lining of the rotating drum.
Next, in order to rotate the rotating drum, the heavy rod rod and all the iron balls must be rotated, so the drive output becomes large, and motors of 75 KW to 150 KW are used in medium class rod mills. Since the power is operated at a voltage of 3,000 volts, the electricity charge is expensive.
Overall, I think that the rod mill is an economically efficient crusher at present when iron is high. However, sand mills are unavoidable in raw plants, so rod mills are currently used nationwide.

機械的エネルギーの強制破砕…採石場で使われている破砕機は大きな岩石を漸次細かく破砕して骨材製品を生産していますが最小破砕は３０ｍｍ前後までで５ｍｍ以下の砂は作れません。
砂を作るには別に細粒破砕機ロッドミルで原石３０ｍｍ以下を破砕して砂を作っています。
現在日本で使用されている石の破砕機は全て機械的エネルギーの強制破砕方式が使用されています。
ロッドミルも機械的破砕方式で同転胴内のロッド棒（５トン〜１０トン）を回転させ重い重量のロッド棒に衝突、すりへりを起こさせ、その中へ原石３０ｍｍ以下と水を投入して破砕させる重力破砕の砂製造機であります。
この製造方法ではロッド棒の激しい損耗で砂の製造原価が高くついています。
この問題を解決するには従来の機械的エネルギーでは解決出来ないのではないかと考えられます。
原石を砂（５ｍｍ以下）に破砕するのは、むつかしい技術であります。
この問題を根本的に解決するには発想を転換して自然のエネルギーに目を転じる必要があります。
自然のエネルギーの自然破砕…川砂、川砂利の原点は河川にあります。河川の形成過程は洪水や雨水などで水が増水し、水のエネルギーで岩石が流され水の中で衝突破砕を繰り返し水にもまれながら、ころがりながら、流されて砂、砂利の角が取れ、粒形の良い川砂、川砂利が形成されて行きます。Forced crushing of mechanical energy: The crushers used in quarries produce aggregate products by gradually crushing large rocks, but the minimum crushing is around 30 mm and sand less than 5 mm cannot be made.
In order to make sand, sand is made by crushing 30mm or less of rough with a fine grain crusher rod mill.
All of the stone crushers currently used in Japan use the mechanical energy forced crushing method.
The rod mill also uses a mechanical crushing method to rotate the rod rod (5 to 10 tons) in the same cylinder, collide with a heavy weight rod rod, cause grinding, and crush it with 30 mm or less of raw stone and water. It is a gravity crushing sand making machine.
In this manufacturing method, the cost of sand production is high due to the severe wear of the rod rods.
It is thought that conventional mechanical energy cannot solve this problem.
Crushing rough stone into sand (5mm or less) is a difficult technique.
To solve this problem fundamentally, you need to change your mind and turn your eyes to natural energy.
Natural crushing of natural energy… The origin of river sand and river gravel is in the river. In the process of river formation, water is increased by floods, rainwater, etc., rocks are washed away by the energy of the water, and crushing and crushing is repeated in the water. A well-shaped river sand and river gravel are formed.

上述のように現在骨材業界で多く使用されている砂製造機のロッドミルはロッド棒並びに鉄のボールの損耗が激しく又高出力のモーターが使用されているので電力料金も多額になっている。このため稼動維持費が高くつき砂の製造コストを押し上げている。
この問題を根本的に解決するには従来の機械的強制破砕ではなく発想を転換して天然河川の川砂、川砂利の形成過程に着目し、河川の原理に準応した鉄のボールの落下エネルギーで原石を破砕する無理のない破砕方法で大量の砂を生産できる破砕機を考案しました。
従来のロッドミルに匹敵若しくはそれ以上の砂の製造能力のあるドラム式川砂製造装置を開発しました。
本発明はこれらの問題を解決するためになされたものであります。As described above, the rod mill of the sand making machine, which is currently widely used in the aggregate industry, has a large amount of power because the rod rod and iron balls are worn out and a high output motor is used. For this reason, the operation and maintenance costs are high, which increases the cost of sand production.
In order to fundamentally solve this problem, instead of the conventional mechanical forced crushing, the idea is changed to focus on the formation process of river sand and river gravel in natural rivers, and the falling energy of iron balls conforming to the river principle We have devised a crusher that can produce a large amount of sand with a reasonable crushing method that crushes the rough.
We have developed a drum-type river sand production device that can produce sand that is comparable to or better than conventional rod mills.
The present invention has been made to solve these problems.

本発明は天然河川での川砂、川砂利の形成過程を機械設備によって人工的に短縮その流路溝によって原石を鉄玉の落下破砕、すりもみ、ころがりの繰り返しを再現することにより大量の川砂を製造するドラム式川砂製造装置であります。  The present invention artificially shortens the formation process of river sand and river gravel in natural rivers by mechanical equipment. By using the flow channel groove, the rough stone is dropped and crushed, and the repetition of rolling and rolling is used to reproduce a large amount of river sand. This is a drum-type river sand production device.

装置の構造は内径３ｍ長さ８ｍの鋼鉄製の円筒形ドラムを作り出力３７．５ＫＷのモーターによりチエン駆動させています。  The structure of the device is a steel cylindrical drum with an inner diameter of 3 m and a length of 8 m, and is driven by a motor with an output of 37.5 KW.

回転ドラムの内側に投入口と排出口を設けその間には巾３５ｃｍ程度の間隔で高さ約４０ｃｍの間仕切り板を多数固着します。
その間仕切り板により区切られた流路溝には１回転に１ヶ所の送り口が設けられており１列目から〜２列目〜３列目へと原石は流動します。
各流路溝には予め鉄のボールが入れてあります。A lot of partition plates with a height of about 40cm are fixed at intervals of about 35cm in width between the inlet and outlet on the inside of the rotating drum.
The channel groove divided by the partition plate is provided with one feed port per rotation, and the rough flows from the first row to the second row to the third row.
Each channel groove is pre-filled with iron balls.

流路溝の内側には溝１ぱいのＶ字形羽根の２階建てが多数取付けてあります。このＶ字形羽根の１階部分は入口は広く出口は狭くなっています。
２階部分は側面は鉄板製で内側には２本の鉄筋でレールが設けてあり鉄のボールはこの鉄筋のレールの上にすくい上げられ落下する構造になっています。A large number of two-story V-shaped blades with one groove are installed inside the channel groove. The first floor of this V-shaped feather has a wide entrance and a narrow exit.
The second floor is made of iron plate on the side and a rail with two rebars on the inside, and the iron balls are scooped up and dropped on this rebar rail.

原石と鉄のボールの落下地点には破砕室が設置してあります。
破砕室の構造は厚い鉄板製で原石が前に流れないように又横逃げしないように止め鋼板で熔接付けしてあります。
破砕室の取付は原石と鉄のボールの落下を鉛直に受けるように流れに沿って高く取付けてあります。There is a crushing chamber at the point where the rough and iron balls fall.
The structure of the crushing chamber is made of a thick steel plate and welded with a steel plate so that the raw stone does not flow forward and does not escape sideways.
The crushing chamber is installed high along the flow so that the fall of the raw stone and iron ball is received vertically.

流路溝の底板には１２ミリ〜１６ミリの鉄筋がＶ字に曲げて取付けてあります。  Reinforcing bars of 12 to 16 mm are bent and attached to the bottom plate of the channel groove.

本発明は天然河川における川砂の形成過程を機械設備によって人工的に短縮、再現、流路溝を作りこれに破砕助材として鉄のボールの落下エネルギーを加えて原石（砕石３０ｍｍ以下と砂利３０ｍｍ以下）を砂の粒子に破砕し、落下、すりもみ、ころがりを繰り返して破砕砂の角を潰し活性面のある、粒形の良い大量の川砂を製造する川砂製造装置であります。
この装置は自然のエネルギーを活用した無理のない川砂の製造方法であり消耗品も少なく、駆動電力も小さく省エネルギーで大量の川砂を製造できる画期的な装置であります。
現在砕石場で使用されている岩石の破砕機はすべて機械的エネルギーで強制破砕で行われています。
砂の製造機ロッドミルも回転胴内に鉄のロッド棒５トン〜１０トンの重い重量のロッドを回転させ、その衝突とすりへりの中で原石を破砕して砂を製造していますので鉄のロッドの消耗は激しく又常時重いロッド棒を回転していますので駆動電力も大きく７５ＫＷ〜１５０ＫＷのモーターが使用されていますので電力料金も高くついています。従いまして砂の製造原価を高く押し上げています。
これに対して本発明の川砂製造装置は河川の原理を機械的に再現したもので自然のエネルギーに順応した自然破砕ですので機械の構造、破砕の方法は全く異なる破砕機でありますが、川砂の製造能力はロッドミルに匹敵若しくはそれ以上の能力があり消耗品に於いてはロッドミルの１０分の１以下となりますし又駆動モーターも３７．５ＫＷと小さく全ての面でロッドミルの欠点は解決されています。The present invention artificially shortens and reproduces the river sand formation process in natural rivers with mechanical equipment, creates flow channel grooves, and adds the falling energy of iron balls as a crushing aid to the raw stone (crushed stone 30 mm or less and gravel 30 mm or less ) Is crushed into sand particles, and it falls, grinds, and rolls repeatedly to crush the corners of the crushed sand and produce a large amount of well-shaped river sand with active surfaces.
This device is a natural river sand production method that uses natural energy, is a groundbreaking device that can produce a large amount of river sand with less consumables, low driving power, and energy saving.
All of the rock crushers currently used in quarries are forced to crush with mechanical energy.
Since the rod mill of the sand making machine also rotates a heavy rod of 5 to 10 tons of iron rod in the rotating drum and crushes the rough stone in the collision and grinding, it produces sand. Since the rod rods are drastically consumed and heavy rod rods are always rotating, the driving power is large, and motors of 75KW to 150KW are used, so the power charges are high. Therefore, the manufacturing cost of sand is pushed up high.
On the other hand, the river sand production apparatus of the present invention mechanically reproduces the principle of rivers and is a natural crusher that adapts to natural energy, so the machine structure and crushing method are completely different crushers. The production capacity is comparable to or higher than that of the rod mill. Consumables are less than one-tenth of the rod mill, and the drive motor is also 37.5KW, so the shortcomings of the rod mill have been solved in all aspects. .

以下本発明の実施形態を説明します。
（イ）機械装置の構造は内径３ｍ長さ８ｍ鋼鉄製の円筒形ドラムを作り図１に示すように回転胴１．鎖車２．ローラーチエン３．受ローラー４．を利用する等通常の駆動方法を用いています。
（ロ）間仕切り板…図２に示すように
回転胴の内側に投入口５排出口及び排出羽根６を設けその間には巾３５ｃｍ程度の間隔で高さ４０ｃｍの間仕切り板７を多数固着します。
その間仕切り板により区切られた流路溝８には１回転に１ヶ所の送り口９が設けてあり１列目から〜２列目〜３列目へと原石は流動します。
各流路溝には図４の鉄のボール１６が予めいれてあります。
（ハ）Ｖ字形羽根の２階建図６の１１
図６の構成図及び図２と図３の配置取付図次に図４の流動図のＶ字形羽根の２階建て１１が流路溝の内側に多数取付けてあります。
Ｖ字形羽根の構造は図６に示すように
１階部分は入口は広く流路溝内巾の寸法に作ってあり出口は狭く高くしてありＶ字形羽根のボックスをなしています。
ドラムの回転に伴って原石（砕石と砂利３０ｍｍ以下）と水が拡散しながら流路溝を流れる際、Ｖ字形羽根は１粒残らず掻き揚げボックスに抱え込み持ち上げます。この際Ｖ字型羽根１１の内部では出口が狭く高くなっているので原石は絞られ原石自体がすりもみされながら盛り上がり出口の先に集められて、ある程度の高さの位置から自然落下を始めます。
Ｖ字形羽根の出口板はボックスの底の原石が落下しやすいように底板に対して３５°に立ててあります。Ｖ字形羽根の底板と側面には鉄筋１２で磨耗防止が施してあります。
Ｖ字形羽根の２階部分は
側面が鉄板製で内側には２本の鉄筋１３でレールが設けてあり流路溝内の鉄のボールはこの鉄筋のレール１３の上にすくい上げられ、ある程度の高さになった時に落下する構造になっています。この際鉄のボールは原石の落下後に原石の上に落下するように作ってあります。
Ｖ字形羽根の２階建ての取付は流路溝の側板にボルトで取付けます。
（ニ）破砕室図４に示すように
原石と鉄のボールの落下地点に破砕室１４が設置してあります。
破砕室の構造は図７に示すように厚い鉄板製で落下してくる原石が前に流れないように止め鋼板と横に逃げないように両側に止め鋼板１５を熔接付してあります。
破砕室の設置は原石と鉄のボールを鉛直に受けるように流れに沿って高く取付けてあります。
図４に示すようにＶ字形羽根の２階建てから落下して来る水と破砕された原石は瀧のように落下して破砕砂の尖った先や角を潰しますと同時に破砕室１４に集められて上から落下してくる鉄のボール１６で更に原石は破砕されます。
破砕された原石と鉄のボールはドラムの回転に伴って流路溝に落下拡散します。
この自然の破砕方法で原石（砕石と砂利の３０ｍｍ以下）は破砕を繰り返し次第に砂の粒子に作られてゆきます。
破砕室の取付けは流路溝の側板にボルトで取付けます。
（ホ）流路溝の底板には図２、図３、図４、図５の１０に示すように
１２ｍｍ〜１６ｍｍの鉄筋１０がＶ字に曲げて６ｃｍ間隔で流路溝の底板に取付けてあります。又側面にも磨耗防止用の鉄筋が取り付けてあります。
この底板の鉄筋１０の働きは鉄筋と鉄筋の間に泥と砂が詰まり、泥と砂によるライニングが出来て底板の磨耗を防ぐと同時に流動する原石と水がこの鉄筋で中央へ中央へと寄せられながら鉄筋を越える度に破砕原石の１群はころころと回転しながらすりもみを繰り返し破砕砂の角が潰れ、丸みのある粒形の良い砂に作られます。恰も天然河川の川砂、川砂利の形成過程に等しい状態を再現します。更にその上を鉄のボールが破砕砂を踏み潰しながら流れてゆきます。
図４の水と原石と鉄のボールの流動図のように次にＶ字形羽根の２階建てに吸収されて行きます。
使用例 私は以前山砂を磨く為に直径３ｍ長さ８ｍの円筒形回転胴を作り、その底板に鉄筋１２ｍｍを６ｃｍ間隔に取付けました処鉄筋の間隔内に泥や砂が詰まり恰も泥や砂によるライニングが施された状態となり磨耗は著しく減少し殆ど無補修のまま約５年間の操業運転を行いました実績があります。Embodiments of the present invention will be described below.
(A) The structure of the mechanical device is a cylindrical drum made of steel with an inner diameter of 3 m and a length of 8 m. As shown in FIG. Chain wheel 2. 2. Roller chain Receiving roller 4. The normal driving method is used, such as using.
(B) Partition plate: As shown in Fig. 2, the inlet 5 and outlet 6 and the discharge blade 6 are provided inside the rotary drum, and a number of partition plates 7 with a height of about 40 cm are fixed between them.
The flow channel 8 divided by the partition plate is provided with one feed port 9 for one rotation, and the rough flows from the first row to the second row to the third row.
Each channel groove is pre-filled with iron balls 16 shown in Fig. 4.
(C) 11 of 2 floors figure 6 of V-shaped feather
Fig. 6 Configuration Diagram and Fig. 2 and Fig. 3 Arrangement Installation Diagram Next, a large number of two-story V-shaped blades 11 in the flow diagram of Fig. 4 are installed inside the channel groove.
As shown in Fig. 6, the structure of the V-shaped blade is a V-shaped blade box with a wide entrance at the first floor and a wide outlet groove with a narrow outlet.
As the drum rotates, the raw stone (crushed stone and gravel 30 mm or less) and water diffuse while flowing through the channel groove, and the V-shaped blades are held in a fried box and lifted up. At this time, since the exit is narrow and high inside the V-shaped blade 11, the rough is squeezed and gathered at the tip of the rising exit while the raw stone itself is rubbed, and begins to fall naturally from a certain height position .
The exit plate of the V-shaped blade is set at 35 ° to the bottom plate so that the rough at the bottom of the box can easily fall. The bottom plate and sides of the V-shaped wing are protected against wear by reinforcing bars 12.
The second floor of the V-shaped blade is made of iron plate on the side, and rails are provided on the inside with two rebars 13, and the iron balls in the flow channel are scooped up on the rebar rails 13 to a certain extent. It is structured to drop when it comes to the moment. At this time, the iron balls are made to fall on the rough after the fall of the rough.
The two-story installation of V-shaped blades is bolted to the side plate of the flow channel.
(D) Crushing chamber As shown in Fig. 4, a crushing chamber 14 is installed at the point where the raw stone and iron balls fall.
As shown in Fig. 7, the structure of the crushing chamber is made of a thick iron plate and welded with steel plates 15 on both sides so that the falling rough does not flow forward and the steel plates do not escape sideways.
The crushing chamber is installed high along the flow so that it receives the rough and iron balls vertically.
As shown in Fig. 4, the water falling from the second floor of the V-shaped blade and the crushed rough fall like a spear and crush the sharp tip and corner of the crushed sand and simultaneously collect them in the crushing chamber 14 The rough is further crushed by the iron balls 16 falling from above.
The crushed rough and iron balls fall and diffuse into the flow channel as the drum rotates.
By this natural crushing method, rough stones (30 mm or less of crushed stone and gravel) are gradually made into sand particles by repeated crushing.
The crushing chamber is installed with bolts on the side plate of the flow channel.
(E) On the bottom plate of the flow channel groove, as shown in FIG. 2, FIG. 3, FIG. 4, and FIG. 5, 10 to 12 mm rebar 10 is bent into a V shape and attached to the bottom plate of the flow channel groove at intervals of 6 cm. There is. Rebars for preventing wear are also attached to the sides.
The rebar 10 of the bottom plate is clogged with mud and sand between the rebar and the mud and sand are lined up to prevent the bottom plate from being worn, and at the same time the flowing rough and water are moved to the center by this rebar. Each time it crosses a reinforcing bar, a group of crushed rough stones are rotated into rolling and repeatedly grinded, the corners of the crushed sand are crushed, and rounded grain-shaped sand is made. Reeds also reproduce the state equivalent to the formation process of natural river river sand and river gravel. On top of that, iron balls flow while stepping on the crushed sand.
As shown in the flow diagram of water, raw stone, and iron balls in Fig. 4, it is absorbed into the second floor of the V-shaped feather.
Example of use I previously made a cylindrical rotating drum 3m in diameter and 8m in length to polish pile sand, and attached 12mm reinforcing bars to the bottom plate at intervals of 6cm. There is a track record of operating for about five years with the lining of sand being reduced and the wear significantly reduced, with almost no repairs.

本発明は以上の構成からなるので本発明を使用するときは
円筒状の回転胴１の投入口５に原石（砕石と砂利３０ｍｍ以下）と少量の水と共に連続的に投入します。１回転の投入量はそのまま１列目の流路溝８に送り込まれ以降は同様に１回転毎に１列づつ原石と水は流動します。
各流路溝８には予め鉄のボールが入れてあります。鉄のボールは常時その流路溝で原石を落下破砕しながら回っています。
流路溝８には一定の間隔を保ちＶ字形羽根の２階建１１が設置されています。流路溝内の原石と水と鉄のボール１６の流れは回転胴１の回転により原石と水は１階の部分のＶ字形ボックスに掻き上げられ鉄のボール１６は２階部分に持ち上げられ、ある程度の高さになりた時に先ず原石と水が自然落下し次いで鉄のボールが落下します。
この際Ｖ字形羽根図６の１階部分のボックス内では入口は広く出口は狭く高くなっているので原石自体が互いにすりもみをしながら盛り上がりＶ字形羽根の先端に集められて瀧のように落下します。この落下により破砕砂の尖った先や角が潰されます。
落下地点には破砕室１４が設置されており落下して来る原石が前に流れないように又横に逃げないように止め鋼板１５が取付けてあります。
この上に落下して来た原石は集められると共に上から落下して来る鉄のボール１６で更に破砕されます。これが自然の落下破砕です。
破砕された原石は回転により破砕室１４より再び流路溝８に流れ拡散します。
流路溝８の底板にはＶ字に曲げた鉄筋１０が６ｃｍ間隔で取付けられています。
この鉄筋と鉄筋の間には泥や砂が詰まり泥と砂のライニングが出来て底板の磨耗を防ぐと共に流動する原石と水が中央へ中央へと寄せられながら鉄筋を越える毎に破砕原石の１群はころころと回転しながら、すりもみを繰り返し破砕砂の角が潰れて丸みのある、粒形の良い流動性の良い砂が作れます。
更にこの流路溝８を流れる原石の上を鉄のボール１６が踏み潰しながら流れてゆきます。
図４の原石と水と鉄のボールの流動図のように次のＶ字形羽根の２階建に吸収されて行きます。
このように原石は入口から出口までただ通過するだけで破砕され角が潰れて粒形の良い光沢のある川砂に等しい良質の砂が大量に製造できます。Since the present invention has the above-described configuration, when using the present invention, the raw material (crushed stone and gravel 30 mm or less) and a small amount of water are continuously charged into the inlet 5 of the cylindrical rotary drum 1. The input amount of one rotation is sent as it is to the channel groove 8 in the first row, and thereafter, the rough and water flow in one row every rotation.
Each channel groove 8 is pre-filled with iron balls. Iron balls are always turning around in the flow channel while dropping or crushing the rough.
A two-story building with V-shaped blades is installed in the channel 8 at regular intervals. The flow of the raw stone, water, and iron balls 16 in the channel groove is caused by the rotation of the rotary drum 1 so that the raw stone and water are lifted up into a V-shaped box on the first floor, and the iron balls 16 are lifted on the second floor, When it reaches a certain height, the rough and water first fall naturally, and then the iron ball falls.
At this time, the V-shaped blades have a wide entrance and a narrow exit in the box on the first floor of FIG. 6, so that the rough stones swell and gather together at the tips of the V-shaped blades and fall like a spear. To do. This fall destroys the sharp edges and corners of the crushed sand.
A crushing chamber 14 is installed at the dropping point, and a steel plate 15 is attached to prevent the falling rough from flowing forward and sideways.
The raw stones that fall on this are collected and further crushed by the iron balls 16 that fall from above. This is natural fall crushing.
The crushed raw stone flows again from the crushing chamber 14 to the flow channel 8 by the rotation and diffuses.
Reinforcing bars 10 bent in a V shape are attached to the bottom plate of the channel 8 at intervals of 6 cm.
Mud and sand are clogged between the reinforcing bars and the mud and sand are lined up to prevent the bottom plate from being worn, and the flowing rough and water are moved to the center while the crossing the reinforcing bar. While the group rotates with the roller, the sand of the crushed sand is repeatedly crushed and the rounded corners of the crushed sand are rounded, making it possible to make sand with good fluidity.
Furthermore, the iron balls 16 flow over the raw stone flowing through the channel 8 while crushing.
As shown in the flow chart of the rough, water and iron balls in Fig. 4, it is absorbed into the second floor of the following V-shaped feather.
In this way, the rough stone can be crushed just by passing from the entrance to the exit, the corners are crushed, and high-quality sand equivalent to glossy river sand with good grain shape can be produced in large quantities.
