Process Training Ball Mill
The better mills on the market have an efficiency of about 8-9 % which means that only 8-9 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ball ...

Industrial Fan solutions for Cement industry applications
In the cement industry coal mill fans are used to supply the required air for burning coal and remove the exhaust gases produced after burning. This is where the coal is grinded into the proper size to be fed into the burner. The coal mill fan moves the coal into the grinder. Thus these fans help ineffective burning of coal inside the mill.
