High Pressure Grinding Rolls HPGRs compress and grind the particle bed in the operating gap between two counterrotating rolls. The floating roll is pressed towards the fixed roll to maintain a working gap and pressure set point. Increasing the operating pressure will increase the kWh/t.
Short shutdown for wear part replenishment. You simply cant afford to shut your operation down frequently to replace wear parts. The wear parts within our High Pressure Grinding Roll are long
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is
Short shutdown for wear part replenishment. You simply cant afford to shut your operation down frequently to replace wear parts. The wear parts within our High Pressure Grinding Roll are longlasting, but also very easy to replace when they do wear
High pressure grinding roll is fixed with two highstrength wearresistant alloy rolls. Their relative rotation generates high extrusion pressure which crushes the material. The material enters into the space

The highpressure interparticle comminution in the POLYCOM#174; is based on the following principle: Brittle material particles are fed to the POLYCOM#174; through a feed bin. The grinding elements are two counterrotating rolls, between which the material is crushed. One roll is designed as a fixed roll and the other one as a floating roll.
HPGR roll diameters typically range from m to m, depending on the supplies, and roll widths vary from m to m. The aspect ratio of the rolls also varies as a
The grinding elements are two counterrotating rolls, one fixed and the other floating, between which the material is crushed. The required comminution pressure is transmitted via the floating roll. This
High pressure grinding rolls (HPGRs), also known as roller presses, are rapidly gaining acceptance in hardrock processing, primarily due to their energy efficiency when reducing mineral ore to fragments.
High pressure grinding roll is fixed with two highstrength wearresistant alloy rolls. Their relative rotation generates high extrusion pressure which crushes the material. The material enters into the space between the two rolls, suffered both extrusion and shear the crowd rolling, cutting and grinding, it is crushed into the required size and then sent by the transport equipment.
