PROCESS TRAINING for operators of Vertical RAW Mills
During heat up there should be a sufficient air flow through the mill to force the heat transfer to the grinding part – forced convection. A sufficient air flow will result in a mill differential pressure of> 5mbar. The duration of heating should be at least until the temperatures after mill and after bag filter reach 85° C.
The 6 Main Process Fans in Cement factory
Fans in cement industry are heavy duty and perform two basic functions i.e., supply of air or removal of exhaust gases and material handling. There are many process fans that find applications in cement industry such as raw mill fans, induced draft fans, cooling fans, raw mill exhaust fans, coal mill fans and cooler exhaust fans.
