    Dolomite Mill Product Introduction

    SBM technology combines the many advantages of previous milling machinery and equipment, fully considers the needs of production and processing in the new environment, and systematically upgrades the dolomite milling equipment. Whether it is dolomite production or processing of other ore materials, it is more It meets the requirements of modern energy-saving and environmental protection and large-scale and efficient production. Its working principle is: large pieces of material are broken into small particles by the crusher and sent to the storage bin of the mill by the elevator, and then passed through the vibration feeder and inclined feed The material tube sends the material evenly to the upper bulk disk of the turntable; the material is scattered to the periphery of the circle under the action of centrifugal force, and falls into the roller ring’s raceway. The processing of the loop becomes powder. The high-pressure fan sucks the external air into the machine through the suction effect and brings the crushed material into the powder separator; the rotating impeller in the powder separator makes the coarse material fall back and regrind, which meets the requirements. The fine powder enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the lower part of the fine powder. The airflow with a small amount of fine dust is purified by the pulse dust collector and passed through the fan. Exhaust muffler.

    The products of dolomite ore after milling are: 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-80 mesh, 80-120 mesh; dolomite ultra-fine powder 140 mesh, 325 mesh, 600 mesh, 1000 mesh, 1600 mesh.

    Structural composition of dolomite mill

    The complete set of dolomite powder mill includes hammer crusher, bucket elevator, storage bin, vibrating feeder, milling machine host, variable frequency classifier, double cyclone dust collector, pulse dust removal system, high pressure fan, Air compressor, electrical control system.

    Dolomite Mill Product Introduction

    Working principle of dolomite mill:

    • 1. During operation, the motor of the main machine of the mill drives the main shaft and the turntable to rotate through the reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway.
    • 2. The dolomite raw mineral material is broken into small particles by a hammer crusher, and then sent to the storage bin by the elevator, and then sent to the upper part of the turntable evenly through the vibrating feeder and the inclined feeding pipe. Bulk tray.
    • 3. The dolomite particles scatter to the periphery of the circle under the action of centrifugal force, and fall into the rolling ring of the grinding ring. They are impacted, rolled, and ground by the ring roller. After three-layer ring processing, the dolomite powder is turned into high-pressure fans. The action sucks the outside air into the machine, and brings the crushed dolomite powder into the machine.
    • 4. The rotating impeller in the powder separator makes the coarse dolomite powder fall and regrind. The fine powder that meets the requirements enters the cyclone powder collector and is discharged by the discharge valve at the lower part of the powder separator. The air stream with a small amount of fine dust is purified by a pulse dust collector and discharged through a fan and a muffler.

    Performance characteristics of dolomite mill:

  • Efficient:
  • When the fineness of the finished dolomite powder and the power of the motor are the same, the output of the dolomite mill is more than double that of the jet mill, agitator mill and ball mill.

  • Long life of wearing parts:
  • Grinding rollers and rings are forged with special materials, which greatly improves the durability. With the same fineness of materials and finished products, the wearing parts of the dolomite mill have a service life that is 2-3 times longer than the wearing parts of the impact crusher and turbine grinder, which can generally reach more than one year; The mill has a service life of 2-5 years when processing calcium carbonate and calcite.

  • High safety and reliability:
  • Because there are no rolling bearings and screws in the grinding chamber, there is no problem that the bearings and their seals are vulnerable, or the machine is damaged due to loose screws.

  • High product fineness:
  • The fineness of the finished dolomite powder processed by this mill can reach D97≤5μm at one time.

  • Low environmental pollution:
  • The use of environmental protection pulse dust collector and muffler in the mill equipment greatly reduces the pollution of dust and noise to the surrounding environment.
