High Pressure Grinding Rolling Mill

1.ISO certificate
2.Simple structure
3.Less power consumption
4.High efficiency and capacity
5.Perfect after-sale service

HPGR has many advantages such as high production efficiency, excellent energy saving, convenient maintenance and good environment etc. It has been considered one of the modst advanced crushing and grinding equipments in the world and widely popularized and applied, such as pellet feed in metallurgical industry and fine crushing and liberation of many mining materials such as iron, copper, gold and diamond.

The technology of HPGR adopts the theory of high pressure applied to the layer of material results in an interparticle comminution. And its characteristic of high production and energy saving are come from this which is largely different from the single particle crushing principle of damp mill and crusher.

When HPGR is working, the material fall down into the gap between two rollers by the gravity action. The rollers transfer the high pressure of the hydraulic system to the material which been sealed in the working area. The pressure is larger than the crushing strength of the material and meanwhile, the materials will crush by themselves and be crushed in different degrees because of the different pressures. The bulk density of the compacted material reaches 85% of its real density. After crushing, the material cakes will be discharged out by the rotating rollers. There are a certain percent of fine grains in the material cakes and some particles filled with micro cracks inside, which results in the Bond work index of the compacted material decreased largely, favorable to the downstream working.

Structure characteristics:

1. The stud roller surface has a longer service life;

2. Planet reducer is the driving unit which has a compact structure.;

3. The hydraulic system has the advanced structure with high reliability;

4. Electric control system adopts PLC and touch screen technology, realizing automatic control of the whole process and convenient operation.

Technical Characteristic

HPGR has the obvious advantages compared with the traditional process equipments such as damp mill for material feed of metallurgical pellet and cone crusher for crushing mining ore before entering grinding.

1. Low energy consumption, only 1~3.5kWh/t;

2. High material throughput;

3. Can grind the material with moisture up to 10%;

4. High reliability and low maintenance cost;

5. Low vibration and noise.
