The horizontal force into the mill housing normally accounts for 1015% of the hydraulic force. The required raw meal quality and capacity are obtained by easily adjusting the grinding pressure, separator speed, gas flow and dam ring height. Great wear resistanceSegmentation of wear parts means low risk of cracking.
