HRC™ high pressure grinding rolls (HPGR) for aggregates. The HRC™ takes HPGR technology to the next level by providing a simple yet robust design that provides flexibility, a low cost of operation and improved product shape.
Primary grinding in the high-pressure grinding roll increases the capacity of an existing dry ball mill operation. Even greater increases in capacity can be achieved if the Polycom is operated in hybrid mode.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Alpine High Pressure Roller Mill The significant difference of high pressure roller grinding compared with compaction is that the press forces between the rollers are lower because no new adhesive forces need to be created.
Is the HPGR grinding alternative right for your application?

In high-pressure grinding roller comminution the feed material is exposed to very high pressure for a short time. The high pressure causes the formation of microcracks in the feed particles and generates a substantial amount of fine material. The pressed material can be fed directly to a given size ball mill, making it possible to increase the ...
If HPGRs are operated correctly, ball mills can be downsized and use smaller grinding media, which substantially reduces steel ball consumption, increases the grinding efficiency and lowers operating costs of the milling substantially.
