Raymond rock grinder or grinding plant is one machine introduced from foreign countries. At present, there are many Raymond grinder manufacturers, and the grinding plant is used for all ores and coal powders preparation, such as fine powder processing of raw material ore, gypsum ore and coal. In the powder rock grinding industry, the main development directions of the Raymond mill are reliability, precision, automatic supervision and control. Such measures as controllable silicon power supply, AC variable frequency speed regulating, grease centralized lubrication and vibration reduction can be taken and the devices such as supervision of working conditions and micro automatic control can be equipped.
The grinder mill or grinding plant crushes and grinds the bulk raw material into the required feeding granularity, after that bucket elevator lifts the material into the storage bin, and then electric vibrating feeder transports it evenly into the grinding chamber where the material is scooped up by shovel blade and grinded between grinder roller and grinder ring, and then the blower blows the air into the grinding chamber from shunt plate and blows the grinded powder into the analysis chamber, the powder is concentrated by rotating analysis impeller that is driven by the speed motor with transmission gear, after the concentration, the large granular material drops back into the grinding chamber and is grinded again, and while the qualified fine powder enters into cyclone powder collector following the air flow.
When the qualified powder separates with air, it is discharged into the final product from the discharging port. In the working process of the host machine, the shovel blade plays the important role. It is in the lower end of the grinder roller and they rotate at the same time when the material is scooped up and thrown into the space between grinder roller and grinder ring thus it shapes litter layer which grinds the material with the pressure force produced by rotating grinder roller so as to achieve the goal of making powder.
1. It is the solid structure, covers small area; it is an independent producing system from primary material to the final powder.
2. Fineness of the final powder is well-distributed, 99% of them can pass through the screen, and other milling machines are hard to approach.
3. Raymond mill conmission equipment adopts closed gear case and pulley, stable convey and believable work.
4. Important part adopt high quality steel, abrasion proof adopt high quality abrasion material, the whole machine have a high abrasion and have a believable work.
5. Its electric system adopt concentrating control, the workshop can realize no-people work, and maintenance.

With qualified products and good service, VIPEAK supplies series Raymond Roller Mill(Raymond Mill), which is suitable for grinding barite, calcite, potash feldspar, talcum, marble, limestone, ceramics, etc.
Working Principle of Raymond Mill
First material should be crushed into the desired size by Jaw Crusher, and delivered to the Silo by Bucket Elevator. Our Designed Vibrating Feeder will feed the material into the grinding room. With the air current from the Air Blower, those powder conforms to the fineness degree will be blew into the cyclone collector and those powder that is not consistent with the desired size will return to the grinding room to be re-ground. The whole system is airtight circulation, and the circulatory flow under the negative pressure.

Raymond mills (Raymond grinder) are those machines that can be used to grind the material into powder in mining, chemical, construction and metallurgy industry.
Raymond mills (Raymond grinder) has been adopted the advanced structure of the same kind machine, and has been upgraded. Compared with Ball Mill, it has the advantages of high-efficiency, low-energy cost, room-saving, low investment. The rollers are tightly pressed on the rings on the account of the centrifugal force. So even the rollers and rings will be grinded to some extent and that will not affect the output. So the roller and rings have long service life, satisfy the customers.
Raymond mills (Raymond grinder) is the circulatory operation, so it is of little dust, environmental protection.
Raymond Mill (Raymond Grinder) is suitable for producing minerals powder, which is widely used in the fields of metallurgy, building materials, chemical, and mining industry. It can be used to grinding calcite, talc, barite, marble, phosphate ore, slag, active carbon, dolomite, granite, chemical fertilizer, compound fertilizer, gold ore, red mud, clay, kaolin, coke, gangue, porcelain clay, kyanite, fluorte , bentonite, heat-resistance material and some other material that Mohfs hardness degree is below 7, and humidity is in 6% non-flammable explosive minerals(about more than 280 kinds). The final product size is adjustable as required in the range of 100-325 meshes (0.125mm-0.044mm).
