Ceramic particles are the latest technology. Their fine-grained structure causes smaller fragments to break during the grinding process, which gives them a 50-200% longer life than Zirc. Zirconia flag discs remove material faster than ceramic flag discs. Ceramic flap discs operate cooler than zirconia and alumina flap discs, reducing heat build-up.

High Pressure Grinding Rolls are generally thought to only be effective in controlled "dry" grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR's the flexibility to fit into a wide array of applications with both wet and dry classification.
Robust HRC™ high pressure grinding rolls (HPGR) 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 floating. The two rotating rollers generate such a high pressure that it grinds the feed ...

1.5.2. High-Pressure Grinding Roll. In high-pressure grinding roll (HPGR), the material is reduced by a highly compressive stress created by two counter-rotating rolls (one fixed and another floating) . This creates a critical fracture process that presses the material into a compact flow area. This flow area is shown in Figure 6.
High-Pressure Grinding Roll (HPGR) stands out as one of the most efficient types of grinding machinery, in terms of energy consumption and the size reduction rate [5]. The prediction of the particle size distribution resulting from comminution in an HPGR device can be estimated using the Population Balance Model (PBM). This mathematical ...
