The air impact pulverization procedure comprises the following steps 1 high-speed airflow ejected by a set of directed nozzles fluidizes the particles, 2 the accelerated material assembles at the nozzle intersection, and 3 concentrated and intense impact, collision, and friction ...
Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or races. The raw coal is then fed into the pulverizing unit along with air heated to approx. 650F from the boiler. Monitoring of temperature levels in the pulverizing process is important to maintain a safe, steady process.
