    Raymond mill




    Raymond mill introduction

    Raymond mill (Raymond roller mill) is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 meshes to 325 meshes according to requirements. It is the main and widely used grinding machine.

    Structure of Raymond mill

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

    2. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill cannot 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 and steel of high quality. The techniques 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.

    Working principle of the Raymond mill

    The Raymond mill can crush the large-size materials to the required feeding size and then will deliver the materials to the storehouse by the dustpan lift, which will be evenly delivered them to the crushing cavity of the main machine body by the electromagnetism vibrating feeder. And the materials which have entered the grinding cavity will receive the grinding between the grinding roller and ring, thus producing the powder, which will be brought to the analyzer to grade by the wind machine. And the required fine powder will enter the large cyclone collector by the air stream to receive the separation and collection .And at last ,the final products will be discharged out by the tripper .And during the working process, the shovel system have played a key important role ,which is positioned on the lower end of the grinding roller .And the shovel and roller will shovel up the materials to the space between the grinding rollers and form the pad layer which will receive the extruding force produced by the rotating of the rollers .And then the materials will be crushed ,thus achieving the aim of the powder making.

    Raymond grinder, Raymond mill for sale

    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, etc. Raymond grinder (Raymond mill) is widely used in the metallurgy, building, chemical industry, mine field. In the chamber of 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 mill can be broadly described as the process of reducing the material to finer size though Raymond mill is different from crushing and granulation.
