Grinding machining milling machine is widely used in mineral products, building materials, chemical industry, metallurgy and materials in the field of mine etc.. According to the grinding fineness and the material discharging material fineness, grinding machine can be divided into Raymond mill, high pressure suspension mill, high pressure powder mill, straight centrifugal mill, overpressure ladder mill, three ring speed milling machines and six types of milling machine. Raymond confidential by the host machine, blower, analysis, product cyclone separator, piping device, motor and other components. The host is composed of a machine frame, a wind inlet volute, blade, roll grinding, grinding ring, a cover casing and a motor. Auxiliary equipment are jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control cabinet, the user can choose flexibly according to the scene.

Raymond mill machine working principle

The material after crushing to the desired size, by the elevator will be the materials to the storage hopper, then through vibrating feeder will feed into the uniform continuous Raymond mill grinding room host, due to the effect of centrifugal force of the rotating, grinding roller swing outwards, pressed on the grinding ring, blade material to scoop up between rollers and ring because of the grinding roller, rolling and achieve the purpose of crushing. Powder after grinding with circulating air blower is brought into the sorting analysis machine, fine through thick materials fall back to the re grinding, qualified fine powder with the airflow into the finished cyclone powder collector, the powder tube, i.e.. On Raymond dilly indoor because be grinding has certain moisture content of material, grinding heat, moisture evaporation, and the whole of each pipe interface is not tight, the external gas is inhaled, so that the circulating pressure increased, ensures the machine to work in the state of negative pressure, gas flow rate increases the pipe into the dust collector through it, is exhausted to atmosphere after purified.

Raymond mill structure features:

  1. three-dimensional structure, small footprint, complete and strong, expect finished powder from the block form up an independent production system;
  2. finished powder fineness uniform rate of 99% through screening, it is difficult for other milling equipment available;
  3. gear and pulley with sealed gear box, transmission smooth, reliable operation;
  4. the important parts are made of high quality steel, wear resistant parts are high-performance materials, machine wear resistance of high, reliable operation;
  5. the electrical system of centralized control, mill shop basically no work can be realized, and maintenance.

High pressure suspension mill scope: hypertension suspended roller mill for grinding barite, limestone, ceramic, slag Mohs hardness of not more than 9.3 level, high fine powder processing humidity below 6% non flammable and explosive mines, metallurgy, chemical industry, building materials and other industries more than 280 kinds of materials, product size in the 80-425 project range adjustment (the most fine 1000 mesh). This machine by adding a special device, can produce 30-80 to coarse powder.
