Raymond mill
It can also be called grinding mill or mountain stone mill. It is a new type of mining grinding equipment. This grinding mill is mainly suitable for mining, building materials, chemical industry, metallurgy and other industries. It can grind limestone, calcite, barite, dolomite, potassium feldspar, marble, talc, gypsum, etc. Kaolin, bentonite, phosphate ore, manganese ore, iron ore, glass, ceramics, activated carbon, carbon black, refractory materials, thermal insulation materials, chemical raw materials, etc. whose Mohs hardness is not greater than grade 1 and whose humidity is below is not flammable or flammable The explosive materials are ground and processed, and the fineness of the finished product can be adjusted arbitrarily between meshes (the smallest mesh).
Working principle of Raymond mill
After the materials to be processed enter the grinding chamber of the main machine of Raymond mill, due to the centrifugal force when the main shaft rotates, the grinding roller swings outward and is pressed against the grinding ring. The blade will The material is scooped up and sent between the grinding roller and the grinding ring, and the grinding and crushing purposes are achieved with the rolling of the grinding roller. After the material is ground, the powder passes through the analyzer with the blower circulating air for sorting. The fine and too coarse material falls back to the grinding chamber for re-grinding. The qualified fine powder enters the cyclone powder collector with the air flow and is discharged through the powder outlet pipe to become the finished product. The airflow passes through the cyclone powder collector and then enters the blower to form a closed loop, so that the machine can work continuously and normally. The residual air enters the dust collector through the residual air duct and is purified before being discharged out of the machine.
Main structure of Raymond mill
The structure of this machine is mainly composed of main machine, analyzer, fan, finished product cyclone separator, micro powder cyclone separator and air duct. Among them, the main machine consists of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring, and a cover
Structural features of Raymond mill
Three-dimensional structure, small footprint, complete set Strong, it has an independent production system from lump materials to finished powder.
The finished powder has uniform fineness and good sieving rate, which is difficult to achieve with other grinding equipment.
The machine transmission device adopts a closed gear box and pulley, with stable transmission and reliable operation.
All important components are made of high-quality steel, and the wear-resistant parts are all made of high-performance wear-resistant materials. The whole machine has high wear resistance and reliable operation. , The electrical system adopts centralized control, which is simple and convenient to use.
