The reliable Hydraulic Roller Press outperforms ball mills and vertical mills when it comes to finish grinding. While the Hydraulic Roller Press can be used to upgrade ball mill systems for energy efficiency and enhanced production benefits, it is also exemplary in upgrading your vertical roller mill.
The roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles microscopic cracks, so that the subsequent fine grinding is easier.
