The crushing balls 7 are stirred by the inner cylinder blades 4 attached in the circumferential direction of the inner cylinder 3 rotated by the driving of the motor 17. The raw material 1 put into the mill is ground by the stirring ball 7 which is stirred, moves to the downstream of the mill to become fine powder, and passes through the aperture 9 of the eyelet 8 and the gap between the eyelet 8 and the end of the inner cylinder 3. , And a product discharge 11 through the discharge port 10.

【発明が解決しようとする課題】前述の従来の横型超微
粉砕ミルにおいて、粉砕ボール７には次のような運動形
態が発生していると推察出来る。In the above-mentioned conventional horizontal ultra-fine pulverizing mill, it can be inferred that the following motion pattern is generated in the pulverizing ball 7.
【０００６】（１）粉砕ボール７の自転運動。(1) Rotational movement of the grinding ball 7.
【０００７】（２）周方向で内筒翼４と筒外翼６が同一

【０００８】（３）粉砕ボール７が内筒３の表面を転勤
しようとする。(3) The grinding ball 7 attempts to transfer to the surface of the inner cylinder 3.

能に陥いる。As described above, the movement modes described in (1) to (3) occur inside the mill, and when the wear to the material is considered, most of the wear occurs slightly but reaches a fatal level. do not do. However, as shown in the enlarged view of FIG. 3, pressure is applied from the crushing ball 7 to both corners of both ends of the inner cylinder 3, the lower end of the eye plate 8, and the lower end of the outer cylinder flange 19. The wear starts from the contact portion, and finally, the crushed ball 7 enters into the lower part of the inner cylinder 3 and the eye plate 8 and becomes inoperable.

ンテナンス費用が莫大となる。Further, the crushed ball 7 is sandwiched between the inner cylinder 3 and the lower part of the eye plate 8 and is broken, broken and mixed into the product powder, which causes a trouble. Further, when abrasion occurs, it is necessary to repair the abrasion point in a short span, so that the maintenance cost is enormous.

発生する。FIG. 3 is an enlarged detailed view of the portion A in FIG. 2 and shows such a state of occurrence of wear. This state will be described in more detail. In the figure, the contact point of one ball of the crushed ball 7 at the corner is the contact between the inner cylinder 3 and the lower two points of the eye plate 8. Upon receiving the weight W of the crushed balls 7 and the pressure P from the other crushed balls 7, their combined force P W is generated.

には粉砕ボール７の大きさまで進行する。Since the crushing ball 7 tends to move in the direction of PW , the above two contact points further advance to the outlet side, and a worn portion 16A is formed on the eyelet 8, and the inner cylinder 3 is constantly rotated. As a result, a worn portion 16B is generated on the entire circumference of the inner cylinder 3 and eventually reaches the size of the crushed ball 7.

を目的としたものである。In order to solve such a problem, the present invention disperses the pressure received from the crushed balls by constructing liners at both ends of the inner cylinder, which are the places where the abrasion is most likely to occur in the horizontal ultra-fine crushing mill. The purpose is to reduce the wear rate.

(1) an outer cylinder having a raw material supply port on the upstream side, a perforated plate for removing powder on the downstream side, and an agitating blade mounted on an inner peripheral surface; An inner cylinder that rotates with; a number of grinding balls inserted between the inner cylinder and the outer cylinder; rotating the inner cylinder, and grinding the raw material while stirring with the grinding balls. In the horizontal type ultra-fine pulverizing mill which discharges from the perforated plate, each is detachably attached to both ends of the inner cylinder, and the inlet side flange surface and the outlet side perforated surface of the outer cylinder are respectively Provided is a horizontal ultra-fine pulverizing mill provided with a liner that forms a continuous surface.

内の内筒端部に発生する摩擦力を両端のライナにより低
減させることができる。According to the present invention, in the method (1), the raw material supplied from the supply port is stirred by a grinding ball between the inner cylinder and the outer cylinder by rotating the inner cylinder. While being crushed, it moves to the downstream outlet side and is discharged as fine powder from the perforated plate. In this process, the frictional force generated at the end of the inner cylinder in the mill can be reduced by the liners at both ends.

大きさまで進行する。That is, the grinding balls at the corners of the inner cylinder and the outer cylinder come into contact with the surface of the inner cylinder at the lower part of the eye plate, receive the weight of the grinding balls and the pressure from other grinding balls, and generate a combined force. Due to this combined force, the inner cylinder is constantly rotating, so that abrasion occurs on the entire circumference of the inner cylinder and the lower part of the perforated board, and eventually the ball reaches the size of the crushed ball.

させることができる。Since the movement form of the crushed ball cannot be changed in order to prevent abrasion, the combined force generated by distributing the pressure received from the crushed ball to the inner cylinder and the eye plate is provided by providing a liner in this portion. As a result, the friction speed can be greatly reduced.

（１）の効果と確実なものとすることができる。In the method (2), since the curvature of the curved surface of the corner portion of the liner is substantially equal to that of the crushed ball, the composite force generated by the crushed ball can be effectively dispersed.
The effect of (1) can be ensured.
