Applications: Vertical coal mill is mainly used for grinding raw coal, bituminous coal, and other fuels into coal powder, which is supplied to rotary kiln and other kilns in the cement plant and thermal power plant. Email: [email protected] 网页A coal mill is also called a coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process. 网页2017年8月28日 control for the supply of pulverized coal mixture. Problem solution The ball mill is a complicated object with an extreme dependence on the productivity of the volume filling of the drum, the form of which is largely dependent on the physical chemical characteristics of raw coal (Figure 1) and is expressed by a transfer function [3,4]: T p A 网页2023年2月10日 Pulverized coal is anthracite, lean coal, coking coal, lignite, etc. It is mainly used to provide heat energy after combustion, and can be used for power generation, steam generation, daily heat source, heating and so on. The infrastructure covers only about 60% of the traditional air-swept ball mill.
