Claims

[Claims for Utility Model Registration] (1) Having an inlet for introducing the material to be crushed on one side in the direction of the rotating shaft of the rotating shaft located in the substantially horizontal direction;
The inside of the mill, which has a slurry outlet for taking out the slurry containing the crushed material on the other side, is divided into a plurality of grinding chambers by a perforated plate along the direction of its rotation axis, and the diameter increases as the grinding chamber approaches the slurry outlet side. In a tube mill that houses small grinding balls,
A tube mill characterized in that each opening formed in the perforated plate is enlarged in the thickness direction of the perforated plate toward the slurry outlet side. (2) Each opening formed in the perforated plate has a cross-sectional shape in the thickness direction of the perforated plate in a trapezoidal shape with the base at the slurry outlet side. A tube mill as described in scope item (1). (3) Each opening formed in the perforated plate has a cross-sectional shape in the thickness direction of the perforated plate consisting of a rectangular part and a trapezoidal part, and the rectangular part is located on the inlet side,
Utility model registration claim (1) characterized in that the trapezoidal portion has a base facing the slurry outlet side.
Tube mill as described in section.
