heat energy of ball mill process in Mexico
Process Training Ball Mill
Fine grinding in general is extremely inefficient. 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.
