Is the roller press the same as the high-pressure roller mill?

Roller press and high-pressure roller mill are actually the same. It's just a different name

The roller press is designed according to the principle of bed grinding, and its main characteristics are: high pressure, full speed, full material and bed grinding. The roller press consists of two extrusion rollers that rotate synchronously and reversely, one is a fixed roller and the other is a movable roller. The material is fed from above the two rollers and continuously brought between the rollers by the extrusion roller. After passing through the high pressure of 100- 150MPa, it becomes a compact cake and is discharged from the machine. The discharged cake contains a certain proportion of fine products. A large number of cracks are generated in the unfinished particles, which improves the grindability of materials and greatly reduces the grinding energy consumption in the further grinding process.

Roller mill mainly includes disc refiner, ring mill, roller mill, Raymond mill, pendulum roller mill, etc. Working principle: the material is crushed by pressure between two rolling surfaces or between a rolling grinding body (ball, roller) and a track (plane, ball, disk); Basic structure: it is mainly composed of grinding track, grinding body, force generation and transmission mechanism, air flow and devices that are convenient for replacing easy-to-replace parts.
