There is. In this configuration, the cylindrical body 100 is rotated at a low speed to scrape the stones filled inside toward the side where the distance between the cylindrical pair 100 and the roller 101 is narrow, and the roller 101 is rotated at a high speed in the reverse direction with respect to the cylindrical body. There is also proposed a sizing machine in which the stone picked up by the tubular body 100 is rubbed with the drum 101 to remove the corners of the stone.

ような観点から角が取れて、実積率が高い川バラスの使
用が推奨されているが、川バラスの採取には限度があ
る。By the way, the stone used as an aggregate of ready-mixed concrete is required to enhance the strength of ready-mixed concrete and at the same time improve the fluidity of ready-mixed concrete. For this reason, it is recommended to use river balas, which has a high volume ratio, but there is a limit to the collection of river balas.

９％よりも高めることができないという問題がある。When crushed stone is used, it is desired to increase the actual volume ratio to 60% or more, which is about the same as that of river ballas.
In the conventional vertical impact sizing machine and horizontal impeller sizing machine, the number of collisions between the objects to be processed or between the objects and the repulsion plate is small, and the stone corners cannot be sufficiently removed.
There is a problem that it cannot be raised above 9%.

しかし、湿式運転は操作方法、メンテナンスなどの面で
面倒な問題があるので、一般には普及していない。In the case of a granulator having a cylinder 100 rotating at a low speed and a roller 101 rotating in a reverse direction at a high speed, the stone is crushed by hitting an edge, and the crushed stone has a sharp corner. Is likely to occur. For this reason, it is not possible to increase the actual volume ratio to 60% or more in dry operation, and it is possible to obtain an actual volume ratio of 60% or more if proper operation is performed in wet operation using a lubricant such as water together with stones. I can only do it.
However, since the wet operation has troubles in terms of operating method and maintenance, it is not widely used.

著しく高くなる欠点がある。The rotation of the cylindrical body 100 exposed to the outside is disadvantageous for improving safety even at low speed rotation. In addition, the outer cylindrical body 100 has four front and rear
Although it is configured to be supported by the receiving roller 102 provided at a certain position, there is a drawback that the weight of the cylindrical body 100 is large, the wearing of the receiving roller 102 is severe, and the maintenance cost is temporarily high.

There is. However, it is necessary to change the residence time of the object to be treated in the cylinder according to the material (especially hardness) of the object. In the above structure, the screw pitch is changed to change the residence time. Is usually near impossible.

An object of the present invention is to provide a crushing / sizing / polishing device capable of carrying out a graining / polishing method.

理物どうしを互いに緩衝させながら摩擦させて被処理物
の角を取る、という技術的手段を採用する。In order to achieve this object, the crushing / grinding / polishing method according to the present invention (hereinafter referred to as the present invention method) has a rotor and at least a part of the rotor located below the rotor. The object to be processed is fed by rotating the rotor between the fixed plate facing the rotor with a space of, and the objects to be processed are rubbed while being buffered to each other between the rotor and the fixed plate. The technical means of removing the corner of the object to be processed is adopted.

のように、被処理物どうしの衝突で被処理物が破砕さ
れ、しかも、被処理物が互いに緩衝し合って衝撃を緩和
するので、被処理物が破砕されるときに新たに鋭い角は
作り出され難い。According to this method, when the object to be processed is fed between the rotor and the fixed plate, a compressive force acts on the object to be processed, but unlike the case where the edge collides with a stone to crush it. For example, when a load is applied to the subgrade of a railroad, or when the subgrade of the roadbed or the surface of a road is stepped on, the objects to be processed are crushed due to the collision of the objects to be processed, and the objects to be processed are Since they cushion each other to cushion the impact, it is difficult to create new sharp corners when the workpiece is crushed.

が十分に丸められることになる。Further, since the objects to be processed are rubbed against each other and the corners are shaved and rounded, the space between the objects to be processed becomes small, and the actual volume ratio is increased. Moreover, since the fixed plate does not move, the movement of the object to be processed near the fixed plate is slow, and the time during which the object to be processed stays between the rotor and the fixed plate becomes long. Therefore, since the objects to be processed rub against each other for a sufficient time and the corners of the objects to be processed are scraped off, the corners of the object to be processed are sufficiently rounded.
【００１６】そして、これらの作用が相乗することによ
り、６０％以上の実積率を得ることができるのである。By the synergistic effect of these actions, a real volume ratio of 60% or more can be obtained.

A technical means is adopted in which a fixed plate facing the rotor at a distance is provided, and a drive means for rotating the rotor around its axis is provided.

As shown in these drawings, this crushing / sizing / grinding device includes a rotor 1, a fixing plate 2 at least a portion of which faces the rotor 1 below the rotor 1 at a predetermined interval, and the rotor 1. Drive means 3 for rotating 1 around its axis (a part of which is shown in FIG. 2).

い。The fixed plate 2 is formed in a cylindrical shape with one end closed, and is provided with a hopper 4 at the end on the one end side where the fixed plate 2 is charged with a rough stone which is an object to be processed. The rotor 1 is arranged in the fixed plate 2 in parallel with the fixed plate 2. The rotor 1 may be arranged at the center of the cylinder forming the fixed plate 2, but may be arranged so as to be biased downward depending on the diameter of the cylindrical fixed plate 2 as shown in the drawing.

It is set according to the grade. For example, in the case of the product 25 mm to 5 mm, the distance between the lower peripheral surface of the rotor 1 and the lower peripheral surface of the fixed plate 2 is set to 50 mm or more, preferably about 200 mm, and in the case of the product 40 mm to 5 mm, the lower peripheral surface of the rotor 1 is set. The distance between the peripheral surface and the lower peripheral surface of the fixed plate 2 is set to 80 mm or more, preferably 300 mm or more.

る。By the way, for example, the input rough stone size is 40 m.
When the test operation was carried out by setting m to 5 mm, the following results were obtained. That is, if this distance is set to 40 mm, stones become trapped between the rotor 1 and the fixed plate 2 and operation becomes impossible, and if it is set to 70 mm, an extremely unstable operation state occurs, and even if operation is possible, the device Since the action is almost a crushing action, the actual volume ratio can only be increased to about 57%. If this interval is set to 100 mm, it is possible to operate, although it is a little strict, but it is thought that the crushing action is about 30%, the sizing action is about 50%, and the polishing action is about 20%. The product rate only rises to about 58%. The distance between the rotor 1 and the fixed plate 2 is 15
When it was set to 0 mm, normal operation was possible, and the throughput was slightly reduced, but an actual volume ratio of about 60% could be obtained. In this case, it is considered that the crushing action is about 20%, the sizing action is about 30%, and the polishing action is about 50%. The distance between the rotor 1 and the fixed plate 2 is 200 m
If it is set to m or more, operation can be performed without problems, and 61% to 63%
We were able to raise the actual volume rate of%. In this case, it seems that about 80% of the action of the apparatus is occupied by the polishing action.

とは避けられない。From the results of these test operations, it has been found that it is preferable that the distance between the rotor 1 and the fixed plate 2 is about 5 times or more the size of the input rough stone. Also, the rotor 1 and the fixed plate 2
Although the processing amount and the actual volume ratio will not be a problem even if the distance between and is further increased to 300 mm and 400 mm, it is inevitable that the apparatus becomes large.

ータ１の回転方向上手側（図１において左側）からロー
タ１と固定板２との間に投入された石が巻き込まれる。When the rotor 1 is rotated in one direction by the driving means 3 at a speed of 250 rpm to 350 rpm, a stone crushed to 40 mm under by secondary crushing is put into the fixed plate 2 from the hopper 4. The stones thrown in between the rotor 1 and the fixed plate 2 are caught from the rotor 1 side (left side in FIG. 1) in the rotation direction.
【００２６】ロータ１と固定板２との間に巻き込まれた

向上手側に戻される。The stone caught between the rotor 1 and the fixed plate 2 is sent to the lower side in the rotational direction of the rotor 1 (the right side in FIG. 1) while receiving a compressive force as the distance between the two becomes narrower. It is flipped up by the rotor 1, passes through the upper side of the rotor 1 and is returned to the upper side in the rotational direction of the rotor 1 with the inner surface of the fixed plate 2 as a guide.

Sometimes, it gradually advances to the open surface 5 side at the other end of the fixed plate 2. Then, after the stones are thrown into the fixed plate 2 from the hopper 4 and repeatedly rotated around the rotor 1 in the fixed plate 2 for a predetermined residence time, the stones are discharged from the open face 5 to the outside of the fixed plate 2. It

合わされて角が丸くなる。During this dwell time, stones repeatedly repeat rotor 1
It is rolled up between the fixing plate 2 and the fixing plate 2 and subjected to a compressive force, so that they are rubbed against each other and the corners are rounded, and the particle size is adjusted to a predetermined particle size. In this sizing process, the stone receives almost no impact force from the rotor 1 or the fixed plate 2, and the stones moved by the rotation of the rotor 1 come into contact with each other and the rotor 1
And, the stones are crushed by the pressure due to the narrow spacing of the fixing plate 2, but the stones near each other, especially the stones in the vicinity of the fixing plate 2 which is slow in moving, exert a buffering action, so that the crushed stones are unlikely to have sharp corners Also, even if a sharp corner is generated, the rotor 1 is repeatedly used.
The stones are rubbed against each other by being wound between the fixing plate 2 and the fixing plate 2, so that the corners are rounded.

The corners of the stone will be sufficiently rounded because they will rub each other and scrape each other's corners.
