立式辊磨机的磨矿过程模拟研究

Abstract

With the sampling from a cement plant, the experiment, such as laser size analysis, general sizing, grindability and rigidity test, was carried out in laboratory. The simulation was done based on the experiment data. A modeling example was given, which used a breakage function and a selection function from the experiment data and experience. It is concluded that the breakage function and the selection function could preferably express the breaking probability of the rock and distributing rule after breakage, that the probability model is a good starting point in model development for the simulation on a vertical roller mill, and that the breakage function and selection function are the key of the matter
