The application layer crushing mechanism of high pressure roller grinding machine developed in the world at present is used in nonferrous mine, oxidation pellet broken grinding typical equipment, it is in recent years in the cement with roller machine based on development of new grinding equipment.
1 high pressure roller mill structure(Tungsten Carbide Corrugator Rolls)
High pressure roller grinding machine is mainly by the following parts: two level set and at the synchronization extrusion roller device of 4 extrusion vice, one of which is the fixed roller, the other through hydraulic system and to provide the hydraulic cylinder pressure promote activities before and after roller little scope mobile, the roll and bearing the composition of the two sets of extrusion roller, through the orientation device installed in the box type structure are composed of three frame, each extrusion roller have their own independent structure of the same transmission device, Magnetic drum separator and through the universal shaft coupling, and hydraulic coupler or safety clutch and planetary gear reducer drive system composed of 1 to transport the energy rolls, material through the adjustable feeding device into two rolls of 2 between material cavity. Central to the equipment, the automatic lubrication system of the bearing the system to provide the grease. High Pressure Roller mill control part mainly according to the test the system to provide the signal, the automatic control system for monitoring equipment, the control can be divided into the machine, site, central control three control mode.
2 the characteristics of the high pressure roller grinding machine
units grinding low energy consumption, Magnetic drum separator high production efficiency because of high pressure roller mill make full use of the laminated broken working mechanism, the energy utilization rate is very high, with the conventional extrusion type super finely crusher and compared grinding machine, crushing probability and grinding characteristics has improved, mainly is the contact point between particles and forces more strong.( Tungsten Carbide Corrugator Rolls)
It can deal with high water content of material grinding process or conventional finely crushing wet material must first will dry material, or use wet ground. Drying is a large energy consumption of the process and the wet grinding products need to precipitate and filtering. But for high pressure roller grinding machine for, roller materials containing some of the best in the water (less than 10%), not only can make a better since birth roller fabric cushion, but also improve the working life of extrusion roller.
In high pressure under the role of grain of group of the materials in the particles in the interior, and mineral and the waste rock around the interface between the local pressure produced numerical range, particle ingredients in the bear the ability of these stress, decided to it were shattered or occurs only deformation. In the treatment of the diamond, the hard mineral take these stress and diamond around the rocks is shattered. For sulfide ore deposits or, because of the nature of the differences between the mineral compositions of the interface happen pieces, and improve the mineral disintegrate degrees.( Corrugated Roll Manufacturer)
