The Prediction of the Density Function of Grain-Size Distribution in the Product of Free Refining

摘要

In this paper it is showed the possibility of analytical evaluating the fraction of arbitrary grain-size class in the product of a single free communition of monolithic, large grain or monodisper-sion sample. It is also proposed the analytical formula for computation when the kinetic energy of grains before collision is known. An analysis has been conducted and disscused about course of proposed density curve of grain-size distribution of product of communition. The method of calculation the fraction of specified grain-size class in the product of a single free communition of polidyspersion dust when the value of grain's kinetic energy and grain-size distribution before collision are known.
