Application:

Series HPGM high pressure grinding roller crusher is specially designed to pre-grind the cement clinkers, the mineral dross, the steel clinkers and so on into small granulars, to ultra-crush the metallic minerals (iron ores, manganese ores, copper ores, lead-zinc ores, vanadium ores and others) and to grind the non-metallic minerals (the coal gangues, feldspar, nepheline, dolomite, limestone, quartz, etc.) into the powder.

Working Principles:

The working principle is to get the effect of crushing and powder grinding by the material bed's mutual squeezing. For the two rollers, one is the fixed, and the other active. They rotate relatively and have the same working speed. After the materials enter from the upper feeder, they can be squeezed to crush under the high pressure between the two rollers, and the fine materials expel from the bottom.

Features:

1. The Driven Part - This equipment only needs one set motor driving. The fixed roller transfers the driven force to the active roller by the dentition-like system, to make the two rollers work together at the same speed. There's no sliding friction, which can effectively save around 45% electricity energy than the common high pressure roller.

2. The Pressure System - Adopting the combined spring mechanical pressure system, the active roller can work flexibly, esp. when the iron impurities enter. This system can guarantee 95% operation rate. While the traditional roller adopts the hydraulic oil system, which lags and easily damages the roller surface and the hydraulic oil system.

3. The Roller Surface - Overlay the alloyed wear-resistant welding materials to get the roller surface with HRC 58-65. The pressure can be adjustable as per the materials' quantity, which can not only realize the crush and the grind, but also protect the roller surface. There's no sliding friction when the fixed roller works together with the active one. Then we can know its service life is much longer than the traditional one.

4. The Working Efficiency -  High working efficiency. Compared with the traditional crushing equipment, its processing capacity increases by 40 - 50%. The processing capacity for PGM1040 is around 50 -100 t/h, with only 90kw power.

5. The Structure - Very compact
