The HPGR (high pressure grinding rolls rollers) is the core equipment of the high pressure grinding process.
The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80 of its solid volume, exceeding its compressive strength with equal pressure being applied to particles of all sizes.
It first used in the cement industry, while nowadays, also have been used in many other industries like nonferrous metal processing, ferrous metal processing, precious metal processing, etc.
The core theory of high-pressure roller grinding is material layer crushing through high pressure. The working principle is static pressure crushing. The crushing effect is got by pressing materials between the two slowly rotating rollers. The high-pressure roll grinding implements a material layer crushing, which is the mutual crushing between materials with very high crushing efficiency. Generally, the energy consumption of high-pressure roller grinding is greatly reduced compared to impact or shear-type crushing equipment.
When the HPGR works, the two rollers make relatively slow movements. One of the rollers is fixed while the other is adjustable and is used to adjust the distance between the rollers. It is the way to control the pressure.
Normally, when the material is continuously fed to the two grinding rolls and goes through them, a certain force is given to the movable roller, thus the material is held by the two rotating rollers and moves downward with the rolls. At this time, in a certain area between the grinding rollers, the material particles will form a material layer.
With the uniform and stable high pressure (100-300MPa) from the rolls, the material particles are squeezed, cracked and crushed.
High pressure roll grinding is normally used as super fine crushing process，which can be as the third or fourth stage of a crushing process, also can be used in the semi-autogenous grinding process for hard rocks.
The input material size for HPGR normally is 20~60 mm，and output size can be less than 3mm. The best input size and output can be chosen accordingly. There are several features compare to the traditional grinding process.
The output size from a normal crushing system is around 12mm, and the size reduction ratio around 5. But the size reduction ratio of HPGR can be up to 10 or even more. It is able to reduce the ore from size 20-70mm to below 3mm.
