Product Details
Introduce
of dolomite
powder processing plant/dolomite grinding
plant:
If you want to processing Dolomite,please choose the following
plant:
YGM
high pressure suspension Raymond roller Mill:
The finished fineness: 15-425 mesh (fineness can be
adjusted)
HGM
superfine powder grinding mill
The finished fineness:325-3000 mesh (fineness can be
adjusted)
European
version of the coarse powder grinding mill
machine:
The finished fineness is less than 3mm.
The purpose of dolomite powder processing
plant/dolomite grinding plant is for grinding materials
with hardness less than 6 in Moh’s scale and humidity less than 6
percent such as kaolin, limestone, calcite, marble,talcum,
barite, gypsum, dolomite, bentonite mud,mica, pyrophyllite,
sepiolite, diatomite, graphite, alunite, fluorite, potassium
feldspar, phosphorite, pigment and so on.
Technical
Advantages of dolomite powder processing
plant/dolomite grinding plant:
● High Efficiency
Under the same finished final size and the same motor power, the
capacity of HGM series micro powder grinding mill is twice as
much as jet mill, mixing grinder and ball mill, and energy
consumption decreased 30%.
● 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
2-3 times longer than impact mill or turbo mill. Furthermore, the
lifetime can reach 2-5 years for grinding calcite
carbonate.
● 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.
● High fineness, flexible adjustment
The final fineness of the grinding materials can be adjusted
between 325 meshes and 2500 mesh (47-5 micron), and the product
fineness can reach D97≤5μm.
●Environment-friendly
The application of pulse bag filter and muffler greatly
alleviates dust pollution and noise.
●Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.
The dolomite powder
processing plant/dolomite grinding plant mainly consist
of hammer crusher , main unit, Frequency conversion classifier,
powder collector, pulse dust cleaner,high pressure positive
blower, air compressor, muffler, electrical apparatus control
system, sound-proof room, crusher, bucket elevator, storage
hopper, and vibrating feeder.
Working
Principle of dolomite powder processing
plant/dolomite grinding plant:
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
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.
