Abstract

This paper describes the structure and pulverization mechansim of a cyclone centrifugal autogenous mill. According to the similarity criteria derived by a basic cquation of bulk dynamic the mil's pulverization resulting from centrifugal force and gravitational force. the similarity criteria suitable for the mills analogue simulation and the calculation formula for the mill's parameters mainly including gemetric similarity ratio are derived. Based on a 300mm-dia.laboratory mill, a 800mm-dia.industrial mil are very close to the calculated values by simulation indicating that it is feasible to perform analogue simulation using the similarity parameter formula.

Keywords：cyclone centrifugal mill: analogue simulation; pulverization mechanism
