Product Details
Vertical grinding plant application:
Vertical grinding plant is the equipment specializing in
producing fine and superfine powder of non-inflammable,
non-explosive and brittle materials with Mohs’s hardness under
six, such as calcite, chalk, limestone, dolomite, kaolin,
bentonite, talc, mica, magnesite, illite, pyrophyllite and
vermiculite, sepiolite, attapulgite, rectorite, diatomite,
barite, gypsum, alunite, graphite, fluorite, rock phosphate,
kalium ore, pumice, etc., totally more than 100 kinds of
materials.
Vertical grinding plant mainly consists of main unit, classifier,
powder collector, dust cleaner, blower, muffler, sound-proof
room, crusher, bucket elevator, storage hopper, and vibrating
feeder.
Working principle of vertical grinding plant
After crushed by hammer crusher, the large materials become small
ones and are sent to storage hopper by elevator, edge of then
evenly sent to the upper distribution plate of the turnplate by
vibrating feeder and sloping feeding pipe. When the grinding mill
is at work, all the grinding rollers are rolling in the ring, and
the materials are driven to the edge of the turnplate by the
centrifugal force and fall down into the grinding chambers where
the materials are repeatedly pressed, crushed and grinded by the
rollers. The high-pressure air blower constantly inhales air
within the grinding mill and, in turn, the air flow with crushed
materials are brought to the classifier whose high-speed impeller
will screen the airflow: the unqualified particle size will fall
and return to the mill for being reground while the qualified
particle size mixed with air will go into the cyclone powder
collector. Most of the qualified powders will fall an exit from
the discharging valve at the bottom; a small proportion of the
fine powders, with airflow, moves to the dust cleaner, and clings
to the surface of the filter bags. At the same time, the fine
powders clinging to the surface fall down by the sudden vibration
of the filter bags, which is caused by the instantly ejected
high-pressure gas controlled by the pulse valve. The materials
from the above two lots are sent by the conveyor at the bottom to
get finished powders packed. In addition, filtered clean air will
be emitted from the air outlet of muffler in the
end.
Features and advantages of vertical grinding
plant:
1. High efficiency
Under the same finished final size and the same motor power, the
capacity of Vertical grinding plant
is twice as much as jet mill, mixing grinder and ball
mill.
2. Long lifecycle of spare parts
The ring and roller are forged by special material with high
utilization. Under the same grinding material and finish special
size, the lifecycle of spare parts is about one year, which is
2-3times longer than impact mill or turbo mill. Furthermore, the
lifetime can reach 2-5 years for grinding calcite
carbonate.
3. High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no
problems caused by bolts shedding or rapid wear of bearings and
seal components.
4. High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted
between 325 meshes and 3000 meshes, and the product fineness can
reach D97≦5um.
5. Environment-friendly
The application of pulse deduster and muffler greatly alleviates
dust pollution and noise.
