Introduction of ultrafine mill
Ultrafine mill also is named Ultrafine grinding mill, micro powder mill,
ultrafine mill is suitable for grinding calcium carbonate into fine
Application of ulrtafine mill
Ultrafine mill is the new type mining equipment for making micro
powders, fine powders,which is widely applied in the industries of
metallurgy, mining, chemistry, cement, construction, refractory
materials, ceramics, and so on.The purpose of the micro powder
grinding millis for super-fine grinding materials with hardness
less than 9 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, carbon
black, diatomite, graphite, alunite, fluorite, potassium feldspar,
phosphorite, pigment, up to 200 kinds.
Ultrafine mill production line
consists of 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.
Working principle of grinding mill
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 airflow 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 and 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.
Technical advantages of HGM Ultrafine mill
1. High Efficiency.
Under the same finished final size and the same motor power, the
capacity of the machine is twice as much as jet mill, mixing
grinder and ball mill, and energy consumption decreased 30%.
2. Long lifecycle of spare parts.
The ring and roller are forged by special material with high
utilization,the lifetime can reach 2-5 years for grinding calcite
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
4. 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.
