Computational Fluid Dynamics (CFD) investigation on …

 — A schematic diagram of the used coal pulverizer is shown in Fig. 1. Typically, in the conventional coal fineness processing, the raw coal is firstly fed into a rotating bowl hub via a centre feed pipe. The rate of coal feed is normally determined automatically by combustion control system, by considering the end-user electrical power (kW or MW ...

Pulverizer Machine Manufacturer

For example, a coal pulverizer is used to grind coal into fine particles so that there is effective combustion. Pulverisers process components in batches or continuously by taking in materials on a conveyor, rotating it, pressing a crusher into it, and then sending the fine particles out. These pulverizer machines can also cool or heat ...
