roller grinding press

SAHUT-CONREUR Roller Press

The roller press is equipped with an hydraulic system able to apply a force on the mobile roll by means of jacks. This force can be different in certain cases on each bearing block of the mobile roll thanks to a double hydraulic circuit. This system also includes safety devices and nitrogen accumulators to dampen the movement and quick return of the mobile roll and protect the Roller Press when tramp material is inadvertently fed to the rolls.

ROLLER PRESSES Finish grinding by Roller Press

grinding technology was born. Prof Klaus Schoenert invented and patented this grinding technology with the title “Method of fine and very fine comminution of materials having brittle behavior”. In the 1980s KHD Humboldt Wedag picked up this idea and pioneered its application with the first industrial Roller Press (RP) for the pregrinding of granulated blast furnace slag. In combination with the invention

Roller press Christian Pfeiffer

Roller press For raw meal or for pre-grinding in two-step grinding processes. 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. When used as a pre-grinding

HPGR High Pressure Grinding Rolls Weir

Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid volume, exceeding its compressive strength with equal pressure being applied to particles of all
