Grinding body

Abstract

The invention relates to a grinding body which is of a regular tetrahedron shape. Edges of the regular tetrahedron and vertex angles are all subjected to arc surface transition treatment, so that planes are in arc surface transition connection. The grinding body provided by the invention and a cylinder body a ball grinder have less relative sliding, so that lifting height is large, throwing area is large, an impact effect is high, and a grinding effect is intensified; the grinding body can generate various contact and impact effects in point, line and surface types, improves the grinder energy utilization ratio, is large in specific surface area, has great frictional force with materials, has a great grinding effect on materials, and has good grinding efficiency.

Description

technical field [0001] The invention relates to a grinding body, in particular to a grinding body used for grinding materials in grinding equipment. Background technique [0002] The grinding of cement clinker has a great impact on the benefits of cement production enterprises, and it is related to two important indicators of cement production energy consumption and cement performance. For a long time, scholars from all over the world have been committed to research on reducing energy consumption in the cement grinding process and protecting ecological balance, believing that this is an important and long-term task. At present, in the production of China's cement industry, ball mills still play a dominant role. The impact of the selection of grinding bodies in ball mills on grinding effect, energy consumption and wear has always been the focus of attention and controversy among domestic and foreign manufacturers. [0003] In the 1930s, Van Erhardt used cubic and spherical m...
