Ultrafine Mill Overview
SCM series super thin mill is on the bases of our company’s production experience for more than 15 years. We absorb advantags from the same trade abroad and at home. We review, research and try on 12 kinds of mills and horizontal hammer crushers. And finally we developed this high-efficiency and low-cost super thin mill by investigation and trial.
This grinding mii is a equipment which produces thin powder and super thin powder. It is applicable to non-flammable and non-explosive materials with hardness less than 6, such as 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.Structural Features
The whole system of the flour mill consists of main unit, deceleration machine, classifier, blower, hammer crusher, dustpan elevator, electro-magnetic vibrating feeder, impulse dust cleaner, piping device, cyclone collector device, classifier, high-pressure motor and muffler.
Ultrafine Mill Features
1. High efficiency in same condition of finished particle size and power of motor, the output is 40% higher than airflow mill and whisk 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. It can be generally one year.
3. High safety because there are no axle tree and bolt in the grinding antrum, there will be no wearout of bearing and sealingpart, also no loose of bolts.
4. Environmental protection It will lighten pollution and noise by using dust cleaner and muffler, which achieves environmental protection requirement.Working Principle
The main motor drives main axle and every layer rotating by reducer. Dail drives numbers of rollers rolling and rotating in the ring by pintles.
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.Superfine Mill Data
