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. The use of HPGR technology also promotes micro fracturing, which can expose minerals encased or locked within a particular ore.

1. Introduction. Since its introduction in the cement industry in 1984, the design and engineering of high-pressure grinding rolls (HPGR), also called roller press, has experienced an appreciable learning and development curve, reaching a status of great acceptance of the technology in different applications in industry (Kellerwessel, …

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces 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 […]

Here, the roll press is used to grind coarse feed material by applying a high pressure between the rolls. During high-pressure comminution, feed material is in effect compacted to a dense flake through exposure to relatively high pressures.

Roller presses are used for more than 100 years for briquetting and compacting several minerals such as coal fines .Since Schönert showed that the comminution of brittle materials is most energy efficient when the particles get compressed between two plates in a particle bed, roller presses got also used for grinding procedures .So-called high pressure …

high press American and European cement grinding circuits have High Pressure Grinding Rollers (HPGR) which increases grinding capacity and energy efficiency.

Our HPGR is a perfect complementary tool to work in conjunction with, and even enhance the performance of traditional grinding mills and fixed-gap crushers. The HPGR exposes feed material to very high pressure for a short amount of time.

A HPGR reduces particles by compressing and crushing the feed between two equally sized, parallel rollers rotating in opposite directions, with a small gap between them. This compresses the feed to 80% of its solid density, where the force of the rollers pushes the rocks against each other and exceeds their compressive strength.
