The grinding Process of the Main Mill is that the transmission device brings along the Central Shaft to drive. The upper part of the shaft connects with the Quincunx Rack, on the frame is loaded with the roller assembly, and forms a swinging pivot. The central shaft does revolve around the central rotation, at the same time it revolves around the grinding rings, and it self also rotates on account of the grinding effect. The shovel system, in the lower part of rollers, is loaded on the lower part of the Quincunx Rack. In the process of rotating of the shovel and the roller, the material will be fed gasket layer between the rollers and ring. The outside centrifugal force (compression force) yielding in this process will process the material into small powder, thus the desired powder is obtained.
1.Blade analyzer is adopted to analysis the powder of 0-400mesh effectively.
2.Oil scale outside the shell can indicate the exact oil level in oil pool.
3.Operation of the mill can be observed through the observation door at any time.
4.Closed gearbox or belt wheel are used as the transmission devices of main unit,stable in transmission and reliable in operation.
5.High quality speed regalating motor is adopoted to adjust the rotation speed of analyzer,and the output size also can be adjusted accordingly.The variable frequency motor also can be used.
6.Comparing with the raymond mill,this grinder is assembled with pressurized spring to improve the mill efficiency.
7.Grinding roller and ring are made of high quality hard alloy and is wear resisting.Customers also can choose other high abrasive materials,such as 65Mn,Mn13Cr2,Cr and chromium cast steel,according to the actual material.
8.Motors are all famous brand,customers can also specify other brands,such as siemens.
High Pressure Medium speed grinder is mainly made up of the mainframe, separator, blower, finished powder cyclone collector, bag filter and connecting pipes, etc. According to usersâ€™ need, the mill can also be equipped with accessory equipments like crusher, bucket elevators, hopper, electromagnetic vibrating feeder and switch box, etc. Inside the mainframe, the roller subassembly is suspended on the roller suspender through horizontal supporting axis, and the roller suspender fixed up with the main shaft and shovel stand. Located outside of the roller bearing house, the pressure springs make rollers push down the inside surface of ring through horizontal supporting axis. Shovels installed on the shovel stand and rollers rotate together when the motor drives main shaft through transmission device and the rollers roll appressed the inside surface of ring and rotate at the same time. The separator impellers are driven by motor through transmission device to rotate, more higher the speed of separator impellor, more fine the powders been separated.
When entering grinding chamber, the raw materials are shoveled up by the shovels and grinded between the rollers and ring; the materials after grinding are brought into the separator along with the air from the blower, and the qualified fine powder became final products and come into the cyclone powder collector, the other unqualified powder fall down to be re-grinded. The circular air returns back to the blower that the above process will be repeated, and the remaining air enters the bag filter in order to protect the environment.
