Grinding head lining plate with reinforcing rib

Abstract

The invention provides a grinding head lining plate with a reinforcing rib. The grinding head lining plate comprises mounting bolt holes. The surface of the grinding head lining plate (3) is provided with the trapezoidal reinforcing rib (2); the upper opening of the trapezoidal reinforcing rib (2) is 20-50mm in dimension; the lower opening of the trapezoidal reinforcing rib (2) is 20-120mm in dimension; the trapezoidal reinforcing rib (2) is 10-40mm thick; and the included angle formed by both sides of a trapezoid is 15-90 degrees. According to a structure adopted by the grinding head lining plate provided by the invention, the trapezoidal reinforcing rib is designed on the working face of the grinding head lining plate, and a steel ball is forcibly lifted by the reinforcing rib when a tube mill rotates, and thereby, the relative friction between the steel ball and a grinding head is reduced, and the grinding head lining plate is protected. The relative friction between the steel ball and the grinding head is effectively reduced by beads of the reinforcing rib, thus, the grinding head lining plate is protected, and thereby, the service life of the grinding head lining plate is prolonged, the crushing capacity of the steel ball to materials is enhanced; the production efficiency of the tube mill is increased; and the running cost of the tube mille is reduced.

Description

[0001] technical field [0002] The invention relates to a grinding head liner, in particular to a grinding head liner with reinforcing ribs. [0003] Background technique [0004] Generally, for tube mills with grinding head liners, when the mill rotates, the steel balls are lifted by friction with the grinding head liners. During the continuous rotation movement, the steel balls wear a lot on the grinding head liners; the grinding body In the similar cascading movement in the tube mill, the grinding body adjacent to the liner of the grinding head will have impact and relative friction on the liner, especially the grinding body accumulated on the side will squeeze the liner, thus forming a positive shape. In this way, the liner of the grinding head wears a lot, especially the upper part of the inner ring of the grinding head, the middle ring, and the lower part of the outer ring. The commonly used tube mill with a grinding head liner has fast wear, high consumption, and f...

AI Technical Summary

Problems solved by technology

Commonly used tube mills with grinding head liners need to be replaced frequently because the liners wear quickly and consume a lot, which affects the production efficiency of the tube mill and increases the operating cost of the tube mill
