Introduction Before asmined coal can be used, it generally must be pretreated to convert it from coarse lumps to a more suitable form. This mainly consists of crushing and grinding (together referred to as comminution), and sorting the resulting particles by size.
size, while low ash bituminous can be crushed to 6mm top size (Singer, 1991). 42 Pulverizing Properties of Coal Coal properties have a great impact on the performance of the coal pulverizing system and the whole boiler. To discuss the coal preparation system and their components, it is necessary to introduce some important coal properties first.

The article gives advice on crusher selection and application. Some factors dictating selection include the desired product size, capacity, Hard Grove grindability index, percentage of rock to be freed and hardness of that rock. The hardness of coal probably has greatest impact on product fineness. 2 refs., 1 fig., 1 tab.
Moreover, crusher manufacturers are making improvements to the equipment that extends the life of the rolls and the average time between maintenance. In the eastern, where a majority of the coal production is washed, primary crushers are usually reducing a 20 to 24inch feed to a more easily conveyed 4 to 6inch top size.
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 twostage pulverizing sec tion.
