Ultrafine Grinding Mill

  • Ultrafine grinding mill outline

    SCM super thin grinding mill is on the basis of more than 15 years’ production experience of our company, we absorb grinding mill technology advantages from the same field abroad and domestic, organizing elite powder processing experts to investigate, research, try again and again.

    And finally we developed this high-efficiency and low-cost super thin mill by investigation and trial.

  • Ultrafine grinding mill details

    ultrafine millApplication area: metallurgy, construction, chemistry, fertilizer and mining, painting, pigment, and cosmetics industry etc.

    Capacity: up to 6800kg/h

    Successfully grinded material: calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alum earth, graphite, fluorite, variscite, potash ore, floatstone and so on.

    Material requirements: non-inflammable, non-explosive and brittle materials Mohs hardness below 9 and humidity below 8%.

    Components of grinding line: SCM series super thin grinding mill consists of main unit, deceleration machine, blower, hammer crusher, dustpan elevator, electro-magnetic vibrating feeder, impulse dust cleaner, piping device, cyclone collector device, classifier, high-pressure motor and muffler.

  • Ultrafine grinding mill features

    1. High efficiency. Under the same condition of finished particle size and power of motor, the output of thin grinding mill is 40% higher than airflow grinding mill and whisk grinding mill.

    2. High using rate of the quick-wear part in same condition of material and finished particle size, the lifetime of the quick-wear part is longer than that of impact crusher and turbine crusher.

    3. High safety. No axle tree or bolt is used in the grinding chamber, so there will be no worn out problem of bearing and sealing parts, and also no loose of bolts in the running of thin grinding mill.

    4. Environmental protection. It will lighten pollution and noise by using dust cleaner and muffler, which achieves environmental protection requirement.

  • Ultrafine grinding mill operating principle

    Big materials are crushed into smaller particles by hammer crusher. Then they are sent to store house by elevator. The electro-magnetic vibrating feeder sends the materials evenly to the middle of the upper dial. Under the function of the eccentricity, the materials scatter to the side of the circle and fall into the ring to be pressed, crushed and milled into pieces by rollers. After the first crush, materials fall into the second and the third layer. The pumping of the high-pressure centrifugal blower put the outside air into the machine. The coarse powder will be brought into the classifier.

    The rotating turbine in the collector makes the coarse particles fall back for regrinding. The fine particles will come into the cyclone collector with the airflow and discharged by the discharging valve on the bottom of the collector. They are the final products. The airflow with little dust will be discharged through blower and muffler after being purified by the cyclone collector.
