The primary grinding is done by the Roller press and finish grinding takes place in Ball mill. Because of this, we can increase the Ball mill capacity as well as the Cement production. Also the feed materials which are coming from roller press to the ball mill are powdery form instead of Clinker material.
The roller press grinding system runs smoothly and reliably. The extrusion roller is forged with alloy steel and has a large bearing capacity. Its unique bearing structure design effectively solves various defects in operation. It has a safe and sensitive hydraulic system and a professional hydraulic accessory design.
Grinding force is provided via hydraulic pumping system and assisted by nitro-charged accumulators. The roller press is designed to operate in choke feed conditions. Feed material is introduced into the gap between the rolls. This action starts to push the moveable roll against the hydraulic rams, compressing the nitrogen in the accumulators.
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 ...

Roller press is a highly efficient communication system where the feed material is exposed under a very high grinding pressure between two solid rollers [ one fixed and one moving ] for a short time due to compression. The high pressure causes formation of micro cracks in the feed material and generates a substantial amount of the fine material.
Covered rolls should be at room temperature and rotated slowly for a few hours before grinding. This will allow the cover to stabilize and round out. Roll grinding Grinding restores the original properties and qualities of the cover. Oxidation, blemishes, surface checks, cuts, and cracks are removed by grinding.
