Partition board for ball mill

Abstract

The invention relates to the technical field of ball mill equipment, and discloses a partition board for a ball mill. The partition board comprises a grate plate; grate seams are formed in the surfaceof the grate plate; cleaning devices are arranged inside the grate seams; and each cleaning device comprises an output-end balancing weight, the output-end balancing weight is glidingly connected with the inner wall of the corresponding grate seam, and a long bolt is arranged on the right side surface of the output-end balancing weight. The grate plate is driven by a barrel to rotate, and the positions and the directions of the grate seams are changed all the time, so that the cleaning devices reciprocate along the grate seams under the action of the gravity of the cleaning devices to clean dirt on the inner walls of the grate seams; by the aid of section triangular scraping strips arranged on the edges of the output-end balancing weights, inlet-end balancing weights and middle balancingweights, the dirt adhering to the inner walls of the grate seams is easier to strip; the dirt adhering to the inner walls of the grate seams is stripped timely and cannot be accumulated layer upon layer on the inner walls of the grate seams, the widths of the grate seams are fixed, material particles after ball milling meet the requirement, the ball milling time is short, and the ball milling production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of ball mill equipment, in particular to a ball mill partition board. Background technique [0002] The ball mill partition board is an important installation component in the ball mill. There are two types of single-layer partition board and double-layer partition board. The single-layer partition board is usually composed of several fan-shaped grate boards. The surface of the grate board is provided with The grate seam, the big end and the small end are provided with threaded holes, the big end is fixed on the barrel of the mill with bolts, and the small end is connected with other grate plates by the central circular plate, and the installed partition plate is round It rotates with the cylinder and is mainly used to divide the grinding body and sieve the materials, to keep the large particles in the coarse grinding chamber, and the materials that have been ground to a size smaller than the grate hole are ...

AI Technical Summary

Problems solved by technology

[0003] 1. Scale is easy to adhere to the inner wall of the grate seam, and the scale accumulates layer by layer, which narrows the width of the grate seam. The material needs to be ball-inked into smaller particles to pass through the grate seam. The material particles after ball milling are too small to meet the requirements. And ball milling time is long, ball milling production efficiency is low

[0004] 2. Scale adheres to the inner wall of the grate seam, so that the inner wall of the grate seam is no longer smooth, and the resistance of material particles passing through the grate seam increases, and it is easy to get stuck inside the grate seam, blocking the grate seam. Over time, the blocked grate seam becomes more and more Many, smooth cross-bin materials are gradually decreasing, and the output is getting slower and slower. It is necessary to stop the machine and let the staff enter the cylinder to clean the grate seam, which is time-consuming and laborious, and the efficiency is low, which seriously affects the production efficiency of the ball mill.
