The Raymond mill was ever popular in mining, building materials, chemical engineering and metallurgy industries for size reduction, dispersion, or specialized needs, powder generation and processing for industrial process. Now MTM series grinding mill<

Product Features: Low Cost And High Performance,Good Stability, High Reliability

working principle

Raymond mill work, will need to crush the material from the hood shell side inlet hopper into the machine, rely on the hanging in the host roller grinding device plum frame, revolves around a vertical axis, and its rotation, due to the centrifugal force during rotation, grinding roller swing outwards, pressed on the grinding ring, between so the blade shovel material sent to the rollers and ring rolling rolling mill roll, due to crushing material objective.

  • Product Parameters
  • Low Cost And High Performance

    The machine is a vertical structure, small occupation area, systematic, from the rough processing of raw materials to delivery to the mill and the final packaging, can become an independent production system.Compared with other grinding equipment, the through screening rates is as high as 99%.

  • Good Stability, High Reliability

    Raymond mill main transmission device adopts closed gearbox and a belt wheel, transmission smooth, reliable operation.An important part of Raymond mill adopts high-quality castings and profiles manufacturing, sophisticated technology, strict process, ensure the equipment durability.

  • Ideal Product Size

    Electrical system adopts centralized control, mill shop basically no work can be realized.

Raymond mill is commonly used for milling equipment. It is used mainly in the 280 species, such as stone, calcite, feldspar, talc, marble, limestone, dolomite, limestone, fluorite, fine powder materials processing activated clay, activated carbon, bentonite, kaolin clay, cement, phosphate rock, plaster, glass, thermal insulation material, does not exceed 9.3mohs hardness non flammable, explosive, mineral and chemical 6% under high humidity, construction and other industries.


Raymond mill mainly consists of the host, fan, product analysis machine, cyclone separator, piping device, motor etc.The main engine is from the frame, the wind casing, the blade, the roller, the grinding ring, the cover and the motor.. Auxiliary device comprises a jaw crusher, bucket elevator, cabinets, electromagnetic vibrating feeder and electrical control of the customer can flexibly according to the actual production situation.

Repair and maintenance of Raymond Mill

  • 1.Raymond mill is in use process, should be in charge of fixed personnel, the operator must have a certain level of technology. Mill before installation on the operator must be the necessary technical training, the principle of understanding milling machine performance, familiar with the operation rules.
  • 2.For Raymond Mill properly, should constitute "equipment maintenance, safety operation system" to ensure the long-term safe operation of the mill, at the same time, it must have the necessary maintenance tools and grease and the corresponding accessories.
  • 3.Raymond mill is used for a period of time, maintenance, also of grinding and grinding ring blade and vulnerable parts of maintenance replacement treatment, grinding roller device before and after the use of connecting bolt and nut should be carefully examined, to see whether the loosening, grease whether full.
  • 4.Grinding roller device which use time more than 500 hours to replace the grinding roller, roller sleeve of the rolling bearing must be cleaned, of damaged parts should be replaced in a timely manner, filling tools available manual oil pump and a grease gun.

The main structure and performance characteristics of Raymond Mill

Raymond mill structure mainly by the host, analyzer, fan, finished cyclone separator, powder cyclone separator and wind pipe. Among them, the host is composed of a machine frame, inlet volute, blade, grinding roller, grinding ring, cover casing.When we using traditional Raymond mill,we found that in processing of calcite powder, 325 mesh powder containing a lot of 10um ultra-fine powder, if can be separated and expand production, greatly improve efficiency. We made a lot of Raymond mill structure renovation.


Materials after grinding, the fan will wind blowing in the machine shell, blowing powder. The analyzer is situated on the top of the grinding chamber separation fine through thick materials and fall into the grinding chamber heavy grinding, the fineness conforms to the specifications of the wind flow into the cyclone collector, collected by the powder outlet discharge, is finished. Airflow from the large cyclone collector is arranged at the upper end of the return pipe back into the fan, wind road is cyclic, and in the state of negative pressure flow, circulating wind path of air volume increased part discharged by the air blower and the host in the middle of the exhaust pipe, into the small whirlwind collector, purification treatment.
