Research and application of grinding technology for high pressure roller mill

The structure of

is mainly composed of the following parts. Two extrusion rollers 4, which are horizontally disposed and rotate synchronously, form an extrusion pair. One is a fixed roller, and the other is a set of two sets of extrusion roll devices, which are composed of rollers and bearing systems, which are driven by the pressure provided by hydraulic system 6 to the hydraulic cylinder before and after the movable roll moves slightly. Each extrusion roller has its own transmission device with the same structure. The energy is transmitted to the roller through the transmission system composed of universal coupling, hydraulic coupling, safety clutch and planetary gear reducer. The material enters the material cavity between the two rollers through an adjustable feeding device 2. The central automatic lubrication system provides grease to all bearing systems in the equipment. The control part of the high-pressure roller mill is mainly based on the signal provided by the test system. The equipment is monitored by the automatic control system. Its control can be divided into three control modes: machine side, field and central control.
