The Raymond grinder (raymond mill) is rather versatile and the Raymond grinder (raymond mill) can be used to grind barite, calcite, kalium, steatite, marble, glass, feldspar, ect. Raymond grinder (raymond mill) is widely used in the metallurgy, building , chemical industry, mine field. In the chamber of Raymond grinder (raymond mill), since the stuff of Raymond grinder (raymond mill) may contain moisture to some extent, the heat generated during makes the moisture evaporated. Raymond grinder further functions may involve drilling, boring or slot producing. Raymond grinder (raymond mill) can be broadly described as the process of reducing the material to finer size though Raymond grinder (raymond mill) is different from crushing and granulation.

Structure of Raymond Mill:
1. The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
2. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach;
3. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably,
4. Main parts of the whole plant are made from cast steel of high quality. The technics is so subtly that insures the durability of whole plant,
5. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
Application:
Raymond grinder(Raymond mill) is mainly used to grind non-inflammable and non-explosive materials with Moth’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.
Working Principle:
Firstly, raw material is crushed by jaw crusher to the size required, then the crushed materials are 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 ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.
