Raymond  mill  Introduction:

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

structure of Raymond  mill:

1. The whole plant is a vertical structure with strong systematic characteristic, so it occupies small area. It is an independent productive system from crushing raw materials to grind and pack.

2. Compared with other milling plants, its passing ratio achieves 99%, which is what others 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 of cast and steel of high quality. The techniques are so subtly that they ensure the durability of the whole plant.

5. The electrical control system is centralizelly controlled, so the automaticity is high, no people needed in the operation room.

Working principle of Raymond mill:

The Raymond mill can crush the large-size materials for the required feeding size and then will deliver the materials into the storehouse with the dustpan lift, then 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  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  plays a key 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 rotation of the rollers. And then the materials will be crushed, thus achieving the aim of the powder making.

Raymond mill for sale:

The Raymond mill is rather versatile and the Raymond mill  can be used to grind barite, calcite, kalium, steatite, marble, glass, feldspar, etc. Raymond mill is widely used in the fields of  metallurgy, building, chemical industry, and mining . In the chamber of Raymond mill, since the stuff of Raymond mill may contain moisture to some extent, the heat generated makes the moisture evaporate. Raymond mill 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.
