What is Raymond Mill?

Raymond mill is appropriate for medium and small sized mines, chemical plants, smelting plants, ore dressing plants, pharmaceutical companies, refractory material factories, cement plant and other powder making industry. Raymond mill belongs to highly efficient closed-circuit ultra-fine grinding equipment that sometimes can replace ball mill. Air flow of Raymond mill is circulating on fan, cyclone separator, pipe and fan. 

It has less exhausted dust and clean operation workshop without pollution to the environment. Raymondmill has high output, wide usage, energy saving, convenient operation, low repairrate and small occupation area, which is the ideal investment equipment forsmall flour enterprises to obtain higher profits. Raymond mill also has othernames for example Raymond pendulum mill, Raymond roller mill and Raymond grindingmill.

Applications of Raymond Roller Mill

Raymond grinding mill is suitable for processing more than 200 kinds of materials of no more than 9 level Mohs hardness and less than 6% humidity. For example, Raymond mill can grind limestone, zinc oxide, ferrous manganese ore, bauxite, talcum, potassium feldspar, calcite, calcium, bentonite, dolomite, active carbon, kaolin, phosphate rock, refractory, thermal insulation material, coal, coke, clay, slag, silica and other materials in non-flammable explosive industry, chemical industry and building materials industry. The processed fine powder can be fitted in the range of 30-800 meshes or higher.

How Raymond Grinding Mill Works?

Grinding Process of Raymond Roller Mill

Rollers hanged on the racks roll around the central axis, which is driven by the gears. At the same time, these rollers rotate on their own axis. The materials are added into the main body of the miller by feeding hopper. Under the effect of centrifugal force, grinding rollers press the grinding rings. The materials are bladed up to where falls between the rollers and the rings. Thus, grinding is expected to be completed by the roller compaction.

Air Separation Process of Raymond Grinding Mill

Air from the fan blows the ground powder up and into the analyzer. Qualified powder flow into the collector, while those are not back to the grinder to have one more process. The air goes back to the fan through the return flue up on the cyclone collector. Air goes in circulation and the extra will be blenched out into another cyclone collector where the waste air is purified.

Difference Between the New and Traditional Raymond Mills

Compared with traditional Raymond mill machine, the new Raymond roller mill is of some superiority.

>>The output size of the materials produced by the traditional type is under 500 meshes, while the new Raymond grinding mill is 800-1,000 or higher.

>>With advanced structure, new Raymond grinding mill operates with lower energy cost, fewer noise and lower failure rate. 

>>Modern technology is adopted to improve the collecting system. More qualified powder is collected instead of being ground again and again.

How to Operate Raymond Grinding Mill Better?

Check whether all the doors are closed rigidly when starting the Raymond grinding mill. Pay attention to the gap between plates to see if it meets the input size and then adjust the rotation speed of the analyzer. Then start the Raymond roller mill in the order of the bucket elevator, crusher, analyzer when materials get in the store and the fan. Lastly start the feeder immediately after the engine of the Raymond mill. When turning off the Raymond grinder, firstly turn the feeder off, and one minute later, the main engine. The fan shall be turned off when the left powder is clear. Power off the analyzer lastly.
