Limestone Micro Powder Grinding Mill Machine Ore Grinding Mill
1. Structural characteristics of micro powder grinding mill Ore Grinding Mill
According to user needs can be equipped with hoist, storage bin,
electric control cabinet, powder feeder, crusher and other
auxiliary equipment. In micro powder mill grinding indoor, roller
assembly through the cross arm shaft mounted on the roller hanger,
roller hanger and spindle and shovel head fixed connection,
pressure spring by pull rod tightly in roller bearing chamber on
the outside of the cantilever end, cross arm shaft, for support, by
spring pressure roller tightly pressed in the inside of ring circle
on the surface, when the motor through a transmission device
rotation, The cutter mounted on the tool rest rotates synchronously
with the roller, and the roller rotates around itself while rolling
on the inner surface of the grinding ring. The analytical machine
drives the impeller of the analytical machine to rotate through the
motor transmission device, and the speed adjustment of the
analytical machine determines the fineness of the powder.

4. Main characteristics of micro powder grinding mill Ore Grinding
Mill
(1) The high pressure micro powder mill has a large application
range compared with the airflow mill.
(2) High pressure micro powder mill compared with the grinding
roller on the material of the grinding pressure under the action of
high pressure spring to provide 800-- 1200Kg. Energy saving, with
the same output and fineness, the system energy consumption is only
one third of the airflow mill.
(3) The investment is small, the benefit is high, in the output and
fineness of the same case, its price is only one eighth of the
airflow mill.
(4) the production process is less, compared with the air flow
mill, the air flow mill must first crush the 20mm material to 100
mesh to be processed into ultrafine powder, and the high pressure
micro powder mill directly from the feed size below 20mm, can reach
the average particle size at one time; 6.5μm to 12.5μm ultrafine
powder.
(5) The grinding device adopts the overlapping multistage seal,
with good sealing performance.
(6) The dust removal effect of the mill completely meets the
national dust emission standard.
