Abstract
The article deals with the issue of the formation of the grain composition of the comminuted material inside the drum of a ball mill. The approach to the calculation of the grain composition at its transition from a larger fraction from a smaller fraction is presented. The proposed approach was tested on an industrial cement ball mill and confirmed on an experimental installation. This approach allows you to determine the parameters of the kinetics of grinding, depending on the design parameters used ball mills.
Highlights
The production of the fine powders is a very important task for any sphere of modern industry
A large number of devices proposed by various researchers for grinding the components of the cement and the Portland cement clinker and additives [6,7,8,9,10,11]
As practice has shown the most important element of technological systems of grinding are closed circuit ball mills. These type of ball mills in the coming decades will remain the basic units for grinding cement clinker and additives [6]
Summary
The production of the fine powders is a very important task for any sphere of modern industry. The material passes the stage of grinding, homogenizing, calcining and grinding again the almost finished product in a finely dispersed powders. At the same time the requirements for quality of the final product to grinding equipment are very high level. To fulfil these requirements all different types of the grinding equipment works in a closed cycle grinding. As practice has shown the most important element of technological systems of grinding are closed circuit ball mills. These type of ball mills in the coming decades will remain the basic units for grinding cement clinker and additives [6]
