Single Driving High Pressure Roller Mill – Series PGM
Short Description:
Application: The Single Driving High Pressure Roller Mill – Series PGM is specially designed to pre-grind the cement clinkers, the mineral dross, the steel clinkers and so on into small granules, 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.
1. Working Principle
The single driving high pressure roller mill is operating as per 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.
2. Driving Part
This equipment only needs one set motor driving. The fixed roller transfers the driving force to the active roller by the dentition-like connection 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.
3. 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 to decompress by that the hydraulic oil is discharged from the pipe, which lags and easily damages the roller surface and the hydraulic oil system.
