325 - 1250 Mesh High Efficiency Vertical Bauxite Grinding Mill Machine
Description
The vertical grinding mill is widely used in such small and medium industries as mining, chemicals, building materials, metallurgy, refractories, pharmaceuticals, cement, etc. It can be used in grinding of quartz, feldspar, barite, Bauxite,calcite carbonate, limestone, talc, ceramic, iron ore,slag, carborundum, bauxite, rock phosphate, coal , etc
【Working Principle】
The motor drives the grinding disc to rotate through the reducer,
the material falls into the center of the grinding disc from the
feed inlet, and the hot air enters the mill from the air inlet.
Under the action of centrifugal force, the material moves to the
edge of the grinding disc, and is crushed by the grinding roller
when it passes through the annular groove on the grinding disc.
Re-grinding, when the material in the airflow passes through the
dynamic and static separator, under the action of the rotating
rotor, the coarse powder falls on the grinding disc for
re-grinding, and the qualified fine powder is milled together with
the airflow and collected in the powder collecting device, which is
product. Moisture-containing materials are dried during contact
with hot gas to achieve the required product moisture.

【Advantage】
1 High grinding efficiency
High grinding efficiency and low energy consumption. Compared with
ball milling, the energy consumption is 40-50% lower, the
single-machine production capacity is large, and low-valley
electricity can be used;
2 The product quality is stable
The material stays in the mill for a short time, reducing repeated
grinding, the product has a uniform particle shape, narrow particle
size distribution, good fluidity, strong adaptability, and the
product contains very little iron, high whiteness and purity;
3 Low noise and environmental protection
The whole system has small vibration and low noise; adopts the
overall sealed negative pressure operation system and the air box
pulse dust removal system, which has no dust spillage, and can
basically realize a dust-free workshop;
4 High reliability
The grinding roller limit device is adopted to avoid the violent
vibration of the mill due to material breakage, and the new
grinding roller sealing device is adopted to ensure reliable
sealing and no need to seal the fan, which further reduces the
oxygen content in the mill and has excellent anti-explosion
performance;
5 High degree of automation
It adopts PLC automatic control system and can realize remote
control, which is easy to operate, easy to maintain and reduce
labor costs;
6 Low operation and maintenance costs
The grinding roller can be turned out of the machine by hydraulic
device, which is convenient for maintenance; the roller sleeve can
be turned over to extend the service life of wear-resistant
materials;
7 Strong drying ability
The hot air can be directly ventilated, and the hot air directly
contacts the material in the mill, and the drying capacity is
strong, and the moisture content of the feed material can reach up
to 15%.
