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.
DetailsThe 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.
DetailsGrinding 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.

DetailsTub-grinding followed by roll-press compaction increased the bulk density by two- to three-fold, and resulted in densified products with bulk density of 190-240 kg/m 3 (12-15 lb/ft 3). Additional increases in bulk density appear possible with improved design of the feeding system for the roll-press compaction machine.
