Product Description

High Pressure Grinding Roll (HPGR) 

High-pressure roller press is a new type of energy-saving grinding equipment, also known as extrusion mill, roller mill or roller press. This equipment can replace the traditional ball mill pre-grinding system with high energy consumption and low efficiency, and at the same time reduce steel consumption and working noise. It is suitable for new plant construction and can also be used for technical renovation of old plants, and can increase the output of the production system by 30% to 50%.

High Pressure Grinding Roll (HPGR) 

The High Pressure Grinding Roll (HPGR) produced by Shanghai Yingyong Machinery Co Ltd (SYM) is an energy-efficient crushing equipment designed for fine and ultra-fine grinding of hard ores and cement materials. It uses two counter-rotating rollers to apply high pressure on the feed material, reducing it by inter-particle crushing and minimizing over-grinding. HPGR is widely used in mining, cement, and metallurgy industries.
