Introduce of
Limestone Powder
grinding plant:
The Limestone Powder
grinding plant mainly consist of hammer crusher , Barite
powder 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.
The purpose of Limestone Powder grinding
plant is for super-fine 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. The granularity of the end products is
325-2500 meshes (0.044-0.0055mm).mainly consist of hammer crusher
, Barite powder 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.
Models of Limestone
Powder grinding plant:
HGM80/HGM90/HGM100/HGM100A/HGM125
Finished graphite powder fineness: 47-5 Bariten
(325mesh-2500mesh)
Capacity: 0.4-12T per hour
Input graphite ore size: ≤20mm
Working Principle of
Limestone Powder 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.
Production Line
Configuration of Limestone Powder grinding
plant:
hammer crusher, bucket elevator, storage hopper, vibrating
feeder, main unit, inverter classifier, cyclone collector, pulse
deduster system, high pressure positive blower, air compressors
and electrical control systems.
Technical Advantages
of Limestone Powder grinding plant:
● High Efficiency
Under the same finished final size and the same motor power, the
capacity of HGM series Barite 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 Bariten), 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.
