High pressure grinding roll is fixed with two highstrength wearresistant alloy rolls. Their relative rotation generates high extrusion pressure which crushes the material. The material enters into the space between the two rolls, suffered both extrusion and shear the crowd rolling, cutting and grinding, it is crushed into the required size and then sent by the transport equipment. Main Technical Parameters

Primary grinding. When the highpressure grinding roll is used as a primary mill, the throughput of existing grinding plants is increased by up to 40% and the energy requirement of the overall plant is reduced by up to 20%. Combi grinding. Used in combi grinding systems, the POLYCOM#174;.
Using an instrumented laboratory highpressure grinding rolls mill, the grinding force, gap dimension, mass flow rate and net mill power were measured for six coals and a crystalline quartz. A technique was developed to estimate the compressive stressstrain curves for compression of the materials in the mill plus the effects of elastic decompression.

#0183;#32;The Hardgrove grindability index (HGI) is a widely used coalquality parameter with applications in coal mining, beneficiation, and utilization. An understanding of the petrology of the coal is fundamental to understanding the validity of the HGI in the given application. The HGI varies with coal rank, increasing (greater ease of grinding) with increasing rank through the highvolatile
