This paper describes the structure and pulverization meshansim of a cyclone centrifugal autogenous mill. According to the similarity criteria derived by a basic equation of bulk dynamics and the mill′s pulverization resulting from centrifugal force and gravitational force, the author has derived the similarity criteria suitable for the mill′s analog simulation and the calculation formula for the mill′s parameters mainly including geometric similarity ratio. Based on a 300 mm dia. laboratory mill, a 800 mm dia. industrial mill is designed. The industrial test has shown that the measured values of the main parameters by the industrial mill are very close to the calculated values by simulation, indicating that it is feasible to perform analog simulation calculation using the similarity parameter formula.
