を有して構成されるものである。[Means for Solving the Problems] A first means for achieving the above object includes a vertical rotating shaft, a vertical rotating shaft that surrounds the rotating shaft at a predetermined interval, and a shaft that is crushed through an upper opening. A Fili-shaped tank body that defines a crushing chamber for introducing materials and pulverizing them and also forms a discharge hole for discharging the processed pulverized materials to the outside; a fixed cutter positioned on the rotating shaft in the radial direction thereof, and for meshing with the fixed cutter to crush the material to be crushed introduced into the crushing chamber and discharging the crushed material from the discharge hole. It is configured with a rotating cutter.

る。[Operation] When the vertical rotating shaft is rotationally driven, the rotary cutter is rotated and the object to be crushed is ready to be crushed. , the fixed cutter and the rotary cutter mesh with each other at the rotating position of the fixed cutter, thereby pulverizing the product. Here, the number of engagements of the crushing cutter with one (specific one) rotary cutter per rotation of the rotary shaft is proportional to the number of rotary cutters.
この結果、粉砕室の被粉砕物取込み能力が向上し、取込
んだ被粉砕物を所定外径に粉砕して排出させるまでの処

せるための空気流を生成する。したがって、所定の外径
まで粉砕された被粉砕物は、上記空気流及び回転カッタ
から受ける遠心力によって槽体の排出穴から強制的に排
出される。As a result, the ability of the crushing chamber to take in the object to be crushed is improved, and the processing time required to crush the taken-in object to be crushed to a predetermined outer diameter and discharge it is greatly shortened. On the other hand, the rotary cutter not only crushes the object to be crushed, but also actively takes in air from the upper opening and generates an air flow for discharging the crushed object together with the air through the discharge hole. Therefore, the material to be crushed that has been crushed to a predetermined outer diameter is forcibly discharged from the discharge hole of the tank body by the air flow and the centrifugal force received from the rotary cutter.
この結果、従来の横型粉砕機のように回転方向における
特定部分の排出孔のみから粉砕物が圭点的に排出される
ようなことがなく、排出孔の日詰まりによる排出不能を
解消できる。As a result, unlike the conventional horizontal crusher, the crushed material is not discharged from the discharge hole at a specific portion in the rotation direction, and the problem of inability to discharge due to clogging of the discharge hole can be eliminated.
そして第２の手段のように垂直回転軸の上端に１しカッ

可能する。Then, as in the second method, if a cutter is integrally attached to the upper end of the vertical rotating shaft, a spiral guide surface is formed in the upper opening to supply the material to be crushed to the pre-cutter.
Since the pre-cutter driven by the vertical rotating shaft crushes the object to be crushed into a predetermined size before being introduced into the crushing chamber, the object to be crushed can be fed into the crushing chamber without causing bridging. In other words, efficient continuous crushing is possible in the crushing chamber.

柱状の固定カッタ６６が取付けられている。As shown in FIGS. 1 and 3, a rotary cutter 60 is integrally attached to the vertical rotation shaft 51 in the pulverized material processing section 3, in addition to the five pre-cutters. The rotary cutter 60 includes a hollow cutter shaft 62 that is fitted into the vertical rotation shaft 51 and integrated by a key 61;
rotary blades 63 mounted on the outer peripheral surface of the shaft at intervals in the circumferential direction; and a rotary cutter 6 having a predetermined rake angle and integrally and replaceably mounted on the tip of each rotary blade 63.
The rotary blade 63 consisting of 4 and 4 is three-dimensionally twisted in the same way as the five pre-cutters, and the resulting rotational negative pressure causes the crushed material to float in the air in the material input section 2. An air flow is generated to forcefully discharge the pulverized material from the discharge pipe 44 via the pulverized material discharge section 4. On the other hand, as shown in FIG. 2, the locking member 34 has fixed cutter housing holes 65 formed along the axial direction on the radially inner end surface, and each fixed cutter housing hole 65 includes: A plate-shaped or prismatic fixed cutter 66 having a predetermined rake angle is attached to mesh with the rotary cutter 64 to crush the pulverized material.

系路中、被粉砕物及び粉砕処理後の粉砕物を洗浄する。Even if the object to be crushed has a complicated external shape to the extent that it can be introduced into the crushing chamber 37 between adjacent rotary blades 63, it is coarsely crushed by the five pre-cutters without causing bridging. The coarsely pulverized material, which has been pulverized to a predetermined external size by the pre-cutter 59, is introduced into the pulverizing chamber 37 between adjacent rotary blades 63 by a forced air flow created by the pre-cutter 59, and is crushed by each rotary blade 63. Forced to rotate. Then, as shown in FIG.
It is crushed by these cutters 64 and 66 in a rotational position in which they mesh with each other. In this case, focusing on the number of times of crushing by one rotary blade 63, the number of times of crushing by one rotary cutter 64 per one rotation of the vertical rotating shaft 51 is proportional to the number of fixed cutters 66 attached to the inner tank 36. The fixed cutter 66 and the rotary blade 63 move the material to be crushed introduced into the crushing chamber 37 into the inner tank 3.
Pulverize until the size is less than the hole diameter of the discharge hole 39 of No. 6,
Only the crushed material crushed to this size can be discharged from the discharge hole 39. The crushed material that can be discharged from the discharge hole 39 is
The forced air flow created by the rotary blades 63 and the rotary cutter 64 of the break cutter 591 and the centrifugal force created by the rotary cutter 64 force the air to be discharged into the discharge chamber 38, and the air is forcibly discharged into the discharge chamber 38 from the drop-in port 20 formed in the shaft support member 19 to the receiving tank. 41 and is discharged to the outside from a discharge pipe 44. in this way,
As the amount of pulverized material that can be simultaneously pulverized increases, and the amount of pulverized material that can be pulverized simultaneously increases, the pulverization processing time is greatly shortened. By the way, the above-mentioned washing water is discharged from the above-mentioned drain pipe 45, and when the supply amount of the washing water is increased, the material to be pulverized and the pulverized material after the pulverization process are washed in the discharge path.

ない。Therefore, unlike a conventional horizontal crusher, the crushed material is not discharged in a concentrated manner only from the discharge holes in a specific part in the rotation direction. By forming the discharge holes 39 at intervals in the circumferential and axial directions, the crushed material is not concentrated only in a specific discharge hole 39, and can be discharged uniformly throughout. Therefore, clogging of the discharge hole 39 can be prevented and the inability to discharge the fluid can be prevented. As a result, the cooperative crushing of the rotary cutter 64 and the fixed cutter 66 is not adversely affected.
したがって従来のスクリーンの面積を半分としても同等

可能である。In the above embodiment, the inner tubs 36... are divided in the circumferential direction and the inner tubs 36... are attached to the locking member 34. It is also possible to form the tank into a cylindrical shape (by forming a plurality of ribs in the circumferential direction) and to separate it from the locking member 34. Furthermore, it is naturally possible to attach the rotary cutter 64 to the rotary blade 63 so as to generate more rotational negative pressure, and configure the rotary blade 63 to actively introduce and discharge air from the upper opening 7IlIJ. .
