Introduction of micro powder grinding mill
Micro powder grinding mill is a device that breaks solid materials into powder by grinding,
Such comminution is an important unit operation in many processes.
It is suitable for producing powder in mineral, chemical, building and
The Handling Materials of micro powder grinding mill
Micro powder grinding mill is suitable for grinding of all kinds of materials whose Moh’s
hardness is below 9.3, such as calcium carbonate, barite, dolomite,
calcite, limestone, kaolin, bentonite, marble, gypsum, quartz,
feldspar, clay, talc, fluorite, clay, white mud, mica, refractory
material, glass, total about 1000 kinds of materials.
Internal structure of micro powder grinding mill
The standard configuration of Micro powder grinding mill consists of main unit, reducer, powder classifier, cyclone powder
collector, dust cleaner, blower, control cabinet motor and pipes.
The optional accessories include crusher, bucket elevator, feeder.
working principle of micro powder grinding mill
1) After crushed by hammer crusher, the large materials become
smaller pieces and are sent to the micro powder grinding mill.
2) When the micro powder grinding mill is at work, the granulated
materials are crushed and grinded by the rollers into particles
3) The high-pressure air blower constantly inhales air within the
micro powder grinding mill.
4) Along with the high speed airflow, micronized materials are
brought to the classifier.
5) The qualified particles are screened and driven into the cyclone
powder collector, finally exit from the discharging valve at the
6) A small proportion of the fine powders, with airflow, moving to
the dust cleaner. Filtered clean air will be emitted from the air
outlet of muffler in the end.
Advantages of micro powder grinding mill
1.ertical structure, so it has small footprint, strong system.
2.Compared with other mills, Raymond Mill has high passing rate -
99%, which is generally not available for other grinding
3.The main drive device of Raymond mill adopts airtight gear box
and belt pulley, the transmission is stable and the operation is
4.Important components are made of high quality castings and
profiles, ensuring the durability of the whole equipment.
5.The centralized control is used in the electric system, the mill
can basically realize unmanned operation, and the maintenance is
