Roller Press | Mill (Grinding) | Materials
Roller press is a highly efficient communication system where the feed material is exposed under a very high grinding pressure between two solid rollers [ one fixed and one moving ] for a short time due to compression. The high pressure causes formation of micro cracks in the feed material and generates a substantial amount of the fine material.

First choice for HPGR technology and service
Comminution principles: high pressure comminution and breakage process between rollers grinding stage. Pressing in a particle bed reduces wear since the main grinding action does not take place between the roll surface and the material, but between the material particles in the particle bed. The throughput of a HPGR depends on the ability
