Rolling press

Roller press is the mid-eighties in the international development of new grinding equipment. The new technology of extrusion grinding has a remarkable effect on energy saving. It has been paid much attention by the international cement industry and has become a new technology to develop the grinding process. The machine uses the principle of high-pressure material layer to crush the low energy consumption, and adopts the working mode of single particle smashing group. Brittle material through high-pressure extrusion (the pressure in the pressure zone is about 150MPa) to quickly reduce the particle size of the material, less than 0.08mm fine powder content of 20 to 30%, less than 2mm of the material to more than 70% All the extruded material in the existence of a large number of cracks, so that the material in the next process grinding, the required energy consumption significantly reduced. According to foreign reports and the actual use of our experience, the use of this equipment than the grinding system without the use of the grinding system can increase production of 50 to 200%, single-production power consumption can be reduced by 20 to 35%. And because the wear roller is small, making the unit wear greatly reduced, while the equipment work of noise, dust, etc. are small, to improve the working environment of workers, fully demonstrated its excellent economic and social benefits.

The main body of the roller press is two oppositely rotating rollers. Brittle material by the conveyor equipment, weighing into the load cell with the load cell, and then through the roller press feeding device into the two same size, the relative rotation between the rollers, the roller side of the material into the nip , While the high pressure between the material will be pressed into a dense material cake, and finally fell from the nip, the transport equipment. The material cake is further dispersed or milled by the next step.
