Three-cylinder bidirectional stepped ball mill

Abstract

The invention relates to the technical field of ball mills, and discloses a three-cylinder bidirectional stepped ball mill. The three-cylinder bidirectional stepped ball mill comprises a ball milling mechanism for performing input type grinding on a material to be ground, the ball milling mechanism comprises an upper outer cylinder, an upper inner cylinder coaxial with the upper outer cylinder is arranged inside the upper outer cylinder, two lower outer cylinders are symmetrically mounted on the lower portions of the left side wall and the right side wall of the upper outer cylinder correspondingly, supporting legs are fixedly mounted on the sides, away from the upper outer cylinder, of the bottoms of the lower outer cylinders, lower inner cylinders coaxial with the lower outer cylinders are arranged in the inner middles of the lower outer cylinders, discharging mechanisms are arranged on the two sides of the inner bottom of the upper outer cylinder, each discharging mechanism comprises a discharging groove formed in the upper outer cylinder, and a driving mechanism is arranged on the outer side wall of the middle of the upper inner cylinder.

Description

technical field [0001] The invention relates to the technical field of ball mills, in particular to a three-cylinder bidirectional stepped ball mill. Background technique [0002] A special form of ball mill is the agitator ball mill. Agitator ball mills comprise a vertically or horizontally arranged, generally substantially cylindrical grinding vessel, which is 70% to 90% filled with grinding bodies. The grinding material suspension is continuously pumped through the grinding chamber. Suspended solids are ground or dispersed by impact or shear forces between the grinding bodies. Separation of ground stock and ground bodies is carried out by means of a suitable separation device at the outlet from the mill. [0003] When the existing ball mill grinds and breaks the material, it generally sets a single group of cylinders, puts the grinding balls inside the cylinder, uses the rotation of the cylinder to drive the balls in the cylinder to roll, and then grinds the balls in t...

AI Technical Summary

Problems solved by technology

[0003] When the existing ball mill grinds and breaks the material, it generally sets a single group of cylinders, puts the grinding balls inside the cylinder, uses the rotation of the cylinder to drive the balls in the cylinder to roll, and then grinds the balls in the cylinder. The material is subjected to impact grinding treatment. This method can carry out high-strength contact impact grinding on the material in the cylinder, but the problem is that because the rotation angle of the cylinder is in a single direction, the ball in the cylinder will be damaged when moving and grinding. , the rolling direction and distance are limited, and the movement of the ball cannot be controlled, resulting in the material in the cylinder not being evenly ground, so that the quality of the final ground material cannot be guaranteed
