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%.
