A Comparison of Three Types of Coal Pulverizers

As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im- pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the two-stage pulverizing sec- tion.

How To Minimize Crusher Fines In A Coal Application

Jun 06, 2019 Each type of coal has differing degrees of friability, meaning how hard it is, how brittle it is and how it breaks up. This is measured by the Hardgrove Grindability Index (HGI). After coal is extracted from the earth, it can be delivered as raw coal to wash plants or reduced to the proper particle size at the mine and transported for its

An assessment of grindability index of coal ScienceDirect

Apr 20, 2002 Therefore, high-moisture coals with less density and higher volume will get more crushing energy. So weight of the undersized material produced in unit time will be more resulting in higher HGI compared to low-moisture coal. So HGI of harder material like high-moisture coals will be apparently high, though the truth is contrary.

Effect of the grinding behaviour of coal blends on coal

fracture. All these properties are influenced by coal rank, petrography, and the type and distribution of minerals. The grindability of a coal blend, as measured by the Hardgrove Grindability Index (HGI), is of great interest since it is used as a predictive tool to determine the capacity of industrial pulverisers in coal-fired power stations.
