Introductions of Raymond Mill:
1. Limestone Raymond mill widely used in grinding equipment of mine, cement, chemical industry, is one of the important equipment of non metallic mineral deep procession.
2. Since its strong stability,adaptability and high cost performance it has popularized in non metallic mineral processing field.
3. Applied in grinding various non plastic ore, mineral soil, metallic oxide, chemical composition etc. which Mohs hardness not more than grade 7, humidity less than 6% non flammable and combustible material such as speckstone, dinas rock, graphite, fluorite, magnesia stone, bentonite, kaoline, pottery clay etc.
Working Principles of 3R Raymond Mill:
1. Big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding.
2. The bevel gear drives the central shaft to the rotate ,the shaft top is connected with a grinding roller hanger,on which a grinding roller device is mounted to form a swinging pivot.
3. The grinding roller device rotates around not only the central shaft but also along the grinding ring, with the grinding roller rotating itself under the action of the friction.
4. The grinding roller hanger has a shovel blade installed at the bottom of roller, the shovel blade and grinding roller throw up and feed the material between the grinding rollers and ring during mutual rotation to form a bedding layer, which will produce an outward centrifugal force ( an extrusion force ) by the rotation of grinding roller to crush the materials.
5. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there.
6. They are discharged at the discharging valve to become finished products; the airflow is sucked to the blower by return pipe on the top of cyclone collector.
7. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
