High strength Raymond mill

  High strength Raymond mill:

  •     Place of origin:
  • China
  •     Brand:Shuguang
  •     Parameter:see form


The High strength Raymond mill is on the basis of Raymond mill, through the improvement of the grinding roller in the studio, the analysis machine modification, air pressure regulation and so on. High strength Raymond mill is suitable for crushing mohs hardness such as barite, pottery and porcelain, slag and limestone is not greater than 9.3, and the humidity below 6% of non flammable and explosive mines, metallurgy, chemical industry, building materials industry more than 280 kinds of materials such as High fine milling processing, fineness of 30-1250 mesh adjusted, and part of the material can be up to 2500 mesh. The special equipment added in the machine can produce the coarse powder of 30-80 purpose.
High strength Raymond mill structure
High strength Raymond mill is mainly composed of main engine, analytical engine, blower, product cyclone separator, piping device, motor, etc. The main engine consists of frame, air inlet and volute, spatula, grinding ring, shell and motor. The auxiliary equipment has jaw crusher, bucket elevator, electromagnetic vibration feeder, etc. Users can choose according to the situation.
High strength Raymond mill working principle
High strength Raymond mill engine, a High pressure spring with a pressure of 1000-1500 kg. After start to work, grinding rod revolve around the spindle, and under the effect of high pressure spring and centrifugal force, close to the ring rolling, the pressure is higher than the same power under the condition of Raymond mill 1.2 times, so the production is greatly improved.
The working process of the host is through the transmission device drives the central axis rotation, with the top of the shaft connected to the plum flower racks, shelves and swinging pivot of roller unit, its not only rotate around the center, at the same time, the revolution at the same time of the roller in the inside of ring, roller rotation itself because of the friction effect. Plum flower rack bottom with a shovel knife system, its position in the lower grinding rod, the shovel with grinding rod cast material shovel feeding in the process of grinding roller and grinding ring, form the packing layer, the material layer is roller outward centrifugal force produced by the rotation of the crushed materials, and that the purpose of pulverizing.
In the mill, there is a certain amount of water in the mill, and the heat generated by the grinding causes the evaporation of the indoor gas to change the air flow. And each pipe junction is not sealed, air is sucked into the outside world, circulate air volume increased, by adjusting the fan for this host ductwork between the air flow to achieve the balance, and import the excess gas inside the bag dust catcher, residual air into small molecule collection down, more gas purified the back out.
High strength Raymond mill advantage
Compared with other Raymond mills, the yield increased by 10-20% compared with that of other Raymond mills. The grinding pressure of the grinding roller to the material increased by 800-1200kgf under the action of high pressure spring
The size range of the finished product is wide, the diameter of the particle diameter can reach 0.613mm (30 eyes), the particle diameter can reach 0.033mm (425 eyes), and the smallest material can reach 0.013mm (1000 eyes).
The mineral materials with a hardness less than 9.3 can be machined and crushed.
The effect of dedusting is completely to the national dust emission standard, and the classifier is easy to adjust.
The grinding device adopts the multi-stage sealing, the sealing property is good.
