Operational parameters affecting the vertical roller mill
The vertical roller mill (VRM) is commonly used for secondary and tertiary crushing processes in numerous industries In this study, the discrete element method of 80mm The raw materials are mixed in a certain proportion and fed into a vertical roller mill (LOESCHE mill) The vertical roller mill grinds the marital to D 85 of 90µm The ground product is calcined in a preheater to 850900℃ After calcination, the materials enter to a rotary kiln and heated to 1450℃ to become clinkerModeling and simulation of vertical roller mill using population
Vertical roller mill
The vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag It has the benefits of simple structure and low cost of manufacture and use Vertical roller mills have many different forms, but they work basically the same All of these forms come with a roller (or the equivalent of rollerMass balance calculations are required to calculate the heat balance From the calculation of the heat balance, it can be seen the heat efficiency of the Vertical Cement Mill toolEVALUASI KINERJA VERTICAL ROLLER MILL (Cement Mill)
