Raymond Roller Mill

Introduction:

Raymond roller mill, also known as raymond mill , raymond grinding mill and raymond grinder, is suitable for grinding non-flammable and non-explosive materials whose Moh’s hardness is below 9.3 and humidity less than 6% such as barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite and lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass and thermal insulation material in mine, metallurgy, chemistry and building industry.

The structure of Raymond roller mill has been perfected after years of practice and improvement. It is widely used for grinding materials in metallurgy industry, building materials industry, chemical industry, mining industry and other areas. It can meet the requirements of different customers with the interaction of the analyzing machine and fan.

Applied Materials of Raymond Roller Mill:

It is suitable for processing various non inflammable minerals with 7 grade Mohs hardness and less than 6% humidity, such as gypsum, talc, calcite, limestone, marble, feldspar, dolomite, barite, granite, kaolin clay, stone, bauxite, oxide iron red, iron ore, etc. The fineness of its finished product is 613-44 microns (0.613 mm -0.044 mm).

Working Principle:

When Raymond roller mill works, the materials that need to be crushed are fed into the machine through the feeding hopper. The grinding roll that hangs on the main engine will rotate around the vertical axis and rotates around itself. Due to the centrifugal force produced in the rotating process, the grinding roll will swings outward and tightly press onto the grinding ring to make the relieving tool scoop up the materials and send them to the space between the grinding roll and the grinding ring, and the materials will be crushed due to the rolling and grinding of the grinding roll.

Raymond Roller Mill Advantages:

1. The whole machine is a vertical structure, so it occupies small area. From crushing of raw material to grinding and packing, it 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. Transmission device of main frame adopts airtight gearbox and pulley, which 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 ensures the durability of whole plant.

5. The electric control system is centralized controlled, so the automaticity is high.
