High-pressure roller mill, also known as "roller press," "squeeze machine" is developed using principles of static crush a crush of new technologies of energy-efficient equipment, is currently the mining industry to achieve "less more broken ground" in Preferred devices. High-pressure roller mill ore put through the static pressure, so that under severe  Roll forming machine  internal injuries caused by a large number of cracks, and even squeezed into finer particles, thereby significantly reducing the workload of subsequent grinding, to increase production, energy saving purposes.

Roller press machine main frame structure, equipped with a fixed roller and a roller set, each set of drivers for the two rollers rotating in the opposite direction slow rotation. Among them, the moving roller hydraulic cylinder in a horizontal sliding driven to do so between the two rollers to maintain a certain gap. When a certain size of the ore material Roll former from the hopper of the machine rely on the top of the vertical feed into the roller gap, in addition to the roll surface in contact with the particles by direct pressure on the roll surface, the space within the ore material was also two relatively rotating The roller compaction, the material particles to withstand more pressure and be crushed in order to achieve continuous grinding process.
