Grinding force is provided via hydraulic pumping system and assisted by nitro-charged accumulators. The roller press is designed to operate in choke feed conditions. Feed material is introduced into the gap between the rolls. This action starts to push the moveable roll against the hydraulic rams, compressing the nitrogen in the accumulators.
grinding rolls for vertical mills in the cement industry The operating parameters of vertical mills are seldom altered once optimum productivity is established. But efficiency improvements – and therefore cost savings – can still be achieved with developments in metallurgy of the grinding element.
