Raymond Mill

SBM Raymond Mill is also called suspended roller mill.As a traditional pendulum mill the Raymond Mill is the star product at the beginning of the SBM company was established.At present,many grinding equipment are derived from Raymond Mill.After years of practice and continuous improvement,its structure is in constant progress and the comprehensive performance index has reached the world advanced level.
SBM Raymond Mill has three different models for you to choose from,the fineness of the finished product can be adjusted from 100 to 425 mesh (35micron) according to requirements.In addition, through the classifier and the draught fan, SBM Raymond Mill can meet the requirements of different users.It has become the first choice of many ultra-fine powder processing.

Application of Raymond Mill

SBM Raymond grinding mill was extraordinary popular in mining, building materials, chemical engineering and metallurgy industries for size reduction, dispersion or specialized needs, powder generation and processing for industrial process.

Whether in earlier years or now,Raymond Mill the significant grinding machine in powder making industry.It is widely used to grind non-flammable and non-explosive materials which Moth’s hardness is below 7,like barite, calcite, potash feldspar, dolomite, gypsum, talcum, mica, marble, limestone, kaolin, clay, coal etc.

Distinctive feature of Raymond Mill

  1. The three-dimensional structure, making the cover area small.
  2. Independent production system can including the rough processing, milling, packaging.
  3. Enclosed gear as transmission, running smoothly and reliable.
  4. Small dust pollution, low noise.
  5. Centralized control of electrical system, realizing the unmanned operation.
  6. Electromagnetic vibrating feeder,feeding uniform,and easy to adjust.
  7. Fuel-efficient and energy saving, easy to maintain.

Working principle of Raymond Mill

When the SBM Raymond Mill is working,raw material should be crushed into the desired size by jaw crusher and delivered to the silo by bucket elevator.Then the vibrating feeder feed the material into the grinding room and 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.
