Raymond roller mill is widely used in calcite, potassium feldspar, talc, barite, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, thermal insulation materials such as mohs hardness is not greater than 9.3, and the humidity below 6% of non flammable and explosive mines, chemical industry, construction and other industries more than 280 kinds of materials of high fine milling processing, R type Raymond roller mill finished product granularity scope of 80-325 mesh and arbitrarily regulate, part of the material up to 600 mesh.

Main structure and Parts

Raymond roller mill is mainly composed of main engine, analyzer, fan, finished cyclone separator, micro-powder cyclone separator and air duct. Among them, the main engine consists of rack, air inlet and volute, spatula, grinding roller, grinding ring and shell.

Working principle

When working, the crushed potash feldspar is added into the machine from the hopper on the side of the hood, and revolves around the vertical axis by means of the roller grinding device suspended on the plum blossom rack of the main machine. At the same time, it rotates itself. Because of the centrifugal force when rotating, the roller swings outward and is pressed on the grinding ring, so that the shovel can lift the material and send it to the grinding roller and the grinding ring. Between them, the purpose of crushing materials is achieved by rolling and rolling of grinding rollers.



1.Raymond roller mill is a vertical structure with a small area and a strong system. It can be used as an independent production system from the raw material processing to the delivery of powder and final packaging.
2. Compared with other grinding equipment, the screening rate is as high as 99%.
3. The main engine transmission device adopts closed gear box and belt wheel, which is stable and reliable.
4. The important parts of Raymond roller mill are made of high quality castings and profiles, and the process is fine, which guarantees the durability of the whole equipment.
5.Raymond roller mill electrical system adopts centralized control, and the selection of advanced and rational automation is high.

As a manufacturer, our newly designed  Raymond mill is more practical, the hardness and wear resistance of grinding rolls, grinding rings and shovels are improved, the service life is generally increased by more than two times, the production cost is reduced, the equipment runs smoothly and without abnormal phenomena, the sealing and lubrication performance of special lubricant paste is good, and the oil-saving is increased by 60%. Performance, operation rate is over 95%, output per hour is increased by over 40%, and economic benefit is good.
