Product Details
Limestone is a sedimentary rock composed largely of the minerals
calcite and aragonite, which are different crystal forms of
calcium carbonate. A few of limestone are composed from skeletal
fragments of marine organisms such as coral or
foraminifera.
Limestone is usually processed in fine or super fine powder by
Vertical limestone powder mill.
Vertical limestone powder mill
is a main kind of stone grinding mill. Limestone grinded by
CLIRIK Vertical limestone powder mill has numerous uses: as a
building material, as aggregate for the base of roads, as white
pigment or filler in products such as toothpaste or paints, and
as a chemical feedstock.
>>The Application of
Vertical limestone powder mill:
HGM125
Vertical limestone powder mill
is mainly applied to non-inflammable, non-explosive and brittle
materials with Mohs’ hardness under six. Such as calcite, chalk,
limestone, dolomite, kaolin, gypsum, etc, totally more than 100
kinds of materials. Product fineness can be controlled between
325~2500 mesh.
>>Working Principle of
Vertical limestone powder mill:
The main bearing and each dial are driven by electromotor of main
machine through reducer, and numbers of rollers, which are
rolling in the ring, are driven by dial through plunger. After
crushed by hammer crusher, the big materials become small ones
and are sent to storage hopper by elevator and further sent to
the middle of first dial evenly by the electromagnetic vibrating
feeder and feeding pipe. The materials will be driven to the edge
of dial by centrifugal force and fall down into the ring, crushed
and grinded by roller, and become powder after production of
three rings. The high pressure centrifugal blower will inhale air
from outside and blow the crushed materials to classifier. The
rotating turbo in the powder concentrator will make the coarse
powder materials return to the mill and reground, while the
fineness will mix with the air and go into the cyclone and be
discharged in the discharge bin, which is at the bottom of it.
The air, which mixed with very little fineness, will be purified
by impulse duster and discharged by blower and
muffler.
>>Performance and features of
Vertical limestone powder mill:
1. High efficiency
Under the same final size and power, the product capacity of
ultrafine mill is twice than jet mill and agitation
mill.
2. Longer lifetime of spare parts
The roller and ring are made of special material, which improve
the grinding efficiency a lot. For same material and final size,
the lifetime of its wearing parts can reach to more than one
year, about 2-5 times as long as that of vertical shaft impact
crusher and turbo-mill. Especially when handling calcium
carbonate and calcite, the lifetime can reach 2-5
years.
3. High safety and reliability:
There are no rolling bearings and bolts in grinding cavity, so
problems caused by bolts shedding or wear of bearings and seal
components will never happen.
4. High fineness of products
The product fineness can reach D97=<5um.
5. Environment friendly
The application of pulse dust collector and muffler reduce the
pollution and noise of the dust, which has reached national
environment protection standard.
