Refurbishment of grinding rolls

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 material to the desired smaller grain size.

The smallest bushing size shown is the smallest allowed for that size wheel. Wheels for steel and stainless steel are aluminum oxide, which is the most common abrasive used in grinding metal. Wheels for aluminum, brass, and bronze are silicon carbide, which cuts through soft metals without generating much heat or causing material buildup.

Thread Rolling & Grinding

In the case of on-site processing, the cost-intensive disassembly and reassembly of the grinding rolls and the refurbishment of the old roll at the original manufacturer's plant both become superfluous. The refiner gap can again be correctly adjusted and the optimal grain size for the material is re-established.

Coolant Filter Paper Roll Manufacturer

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 ...
