The machine is used to grind barite,limestione,ceramics,etc,such non-inflammable and nonexplosive stuff,which the hardness is below 9.3 Mohs and moisture is less than 6% in the trades of mining,metallurgy,chemical engineering and construction material.The fineness size is adjustable in the range of 60-1250 mesh (it can even reach to 2500 mesh).It is possible to produce 10-60 mesh powder through assembling special device in the machine. When the stuff is loaded into the grinding cavity,it is hoveled into the space between the roller and the ring for grinding. The grinded powder goes into classifier along with the circulation wind of the blower and the standard fineness powder is guided to the cyclone collector as finished and lager size stuff falls back to the grinder for regrinding. The circulation wind returns to the blower to repeat the above process and the after wind enters into bag dust cleaner for purification.


1. The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to gringding and packing is an independent production system.

2.Compared with other milling plants, its passing ratio achives 99%, this is what other mill can not reach.

3.Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates main parts of the whole plant are made from cast and steel of high quality. The techinics is so subtly that insures the durability of whole plant.

4.The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.


Raymond mill supplied by Shanghai Xuanshi is mainly used to grind non-inflammable and non-explosive materials with Moh’s hardness below 7 and moisture content below 6% such as barite, calcite, potash feldspar, talcum, marble, limestone, ceramic, glass, etc. Raymond grinder can be used in mining, chemical industry, construction materials, metallurgy and so on. The final products can be adjusted freely from 100 mesh to 425 mesh.

Working Principle:

Firstly, raw material is crushed by jaw crusher to the size required, then elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between the ring and rollers to accomplish the grinding. After grinding, the rough materials will be recycled by the air from the fan back into the grinding chamber for regrinding and the fine powders are blew into the cyclone and poured out through the output-powder pipe as the final products.
