How pellet mill works - pellets-wood

Pellet Mill Forces., In order to fully understand how a pellet mill works, one must be aware of the forces and how they are applied within the pelleting chamber. In particular, one must look at the forces acting on a wedge of feed at the nip point of the pellet mill. This is the heart of the process as illustrated on Figure 3.

Coal Based Fuel Feeding System for Boiler

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 conveying of the pulverized coal from coal mills to the furnace area.
