Description

[0002] Roller press is a special equipment used for material rolling processing, mainly composed of frame, roller, bearing, transmission components, etc. Roller press consists of two squeezing rollers that rotate synchronously in opposite directions, one is a fixed roller and the other is a movable roller. The material is fed from above the two rollers and is continuously brought into the roller space by the squeezing rollers. After being subjected to high pressure, it becomes a dense cake and is discharged from the bottom of the machine. Ordinary roller press consists of frame, two roller systems, transmission device, torque support, roller cover, feeding device, hydraulic (pressurization) system, main bearing lubrication system, dry oil lubrication system, electrical system, roller removal device, etc. In addition to the main parts and devices of ordinary roller press, precision roller press has added devices to ensure calendering accuracy.
