Typical size ranges would start with run-of-mine coal feeding to the primary sizer at 2000 mm, and reducing to 350 mm. The secondary sizer would receive this coal and discharge at a nominal 125 mm, followed by a tertiary sizer/screen combination to generate a 50 mm topsize preparation plant feed (FL, 2011).
2021-8-10 · The coal is first crushed into minute particles using equipment called pulverizes. The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for ...
Teeth roller coal crusher principle is: the fuel enter from up, and discharge directly from bottom outlet, without secondary crushing. To achieve the crushing purpose through crushing and screening by snap action between teeth, the grain evenly, over powder rate is very low, and its broken particle size can be quickly adjusted by the screw, to fully meet the requirements of coal …
