QM-3 Ball Mill
Product Detailed

This ball mill also called mill for measuring bond work index is a key device for measuring grinding work index.


QM-3 Ball Mill


Grinding function index (BOD), referring to the grindability index of cement raw materials and mixtures, is used to indicate the grinding difficulty of the material. It is measured according to the principle that to calculate the grinding work index based on output of each revolution of the mill after the material is ground to a balanced state by the specified mill. This ball mill, also called mill for measuring bond work index, is a key device for measuring grinding work index. It is widely used by teaching and  researching departments for grindability test of cement raw materials and mixtures.

QM-3 Ball mill also applies to ceramics, chemical industrial laboratory and  factory small batch production materials fine grinding. This machine is composed of the mechanical transmission mechanism, electric control and grinding volume three parts, with characteristics of simple structure , easy to use, convenient operation and maintenance, etc.
