High pressure grinding rolls (HPGR) Metso
High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals. The smaller models of the HPGRs are particularly productive in producing manufactured sand for
High Pressure Grinding Rolls (HPGR) TAKRAF GmbH
HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming increasingly popular. The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and

Garnet Wikipedia
Mixed with very high pressure water, garnet is used to cut steel and other materials in water jets. For water jet cutting, garnet extracted from hard rock is suitable since it is more angular in form, therefore more efficient in cutting. Garnet paper is favored by cabinetmakers for finishing bare wood. Garnet sand is also used for water filtration media. As an abrasive, garnet can be broadly
