SCM Grinding Mill Introduction:
SCM series super thin grinding 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 grinding mills and horizontal hammer crushers. And finally we developed this high-efficiency and low-cost super thin grinding mill by investigation and trial.
This grinding mii is a equipment which produces thin powder and super thin powder. SCM series grinding mill 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.
SCM Grinding Mill Features and Benefits
◆ High efficiency In same condition
of finished particle size and power of motor, the output is
40% higher than airflow grinding mill and whisk grinding mill.
◆ 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.
◆ 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.
◆ Environmental protection It will lighten polution and noise
by using dust cleaner and muffler, which achieves environmental
protection requirement.
SCM Grinding Mill Structural characteristic and working principle:
The whole system of the flour
grinding 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.
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 send 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.
