Silica powderfrom natural quartz or quartz ( natural quartz melting at high temperature, cooling after the amorphous SiO2) by crushing, milling

 ( or vibration, the airflow mill ), flotation, pickling purification, high-purity water treatment and other multi-channel processing of powder.

 Silica is a non-toxic, tasteless, non-polluting inorganic nonmetallic material. Because it has good temperature resistance, acid and alkali 

corrosion resistance, low thermal conductivity, low thermal expansion, high insulation, chemical stability, high hardness, good performance,

 are widely used in chemical industry, electronics, integrated circuits ( IC ), electrical appliances, plastics, coatings, paints, rubber, 

senior defense fields. With the rapid development in the field of high technology, microsilica also will enter a new historical period of 

 development.

Silicon powder ultra-fine processing technology is the most classic ball + Superfine Classifier Technology ( requires high purity products

 using jet mill technology ), its main equipment characteristics:

Ball mill:

According to German ultra-fine filler level of mineral processing design

Optimization of the length to diameter ratio of ball mill

Grate plate mill tailing discharging, discharging smooth, free up wear, cylinder body without cooling

Liner and grinding medium with high aluminum material, to ensure the purity of the product

The grinding medium according to the requirement of products and reasonable ratio, high filling rate, high efficiency

Optimization of drive and grinding power matched, maximize energy savings

And the classifier to form a closed system, negative pressure conveying, no dust

Classifier:

Selection of Germany the latest design of the vertical or horizontal single rotor classifier rotor Superfine Classifier

Precise flow control to ensure excellent vertex cut

The adjustable flushing flow, improve the efficiency of classification

Classification of materials directly into the region to be graded coarse powder mixture

Optimization design of low power consumption to rotor

Through the different classifier alignment regulating product size distribution, to meet the different technical requirements of the product

Quantitative system:

Ball mill feed using precise quantitative system, even if the material density change can also be stable feeding

Classifier using precise quantitative feeding system, and with the ball mill discharging interlock, ensure system operation and product size stability

Flow regulating valve with flow measurement system for grading, air flow rate and velocity control

Control system:

Warehouse and product warehouse of material level device, can realize the automatic control of production line

Adopting PLC control flow chart display, lighting operation and error, clear, easy to operate

Environmental protection and noise control:

The deposited film bag processing, waste gas dust emissions below 20mg / m³

Application of high efficient silencer, exhaust noise < 80dB ( A )

All moving parts are heavy shock absorber

No waste water discharge, the only ball bearing cooling water, can be recycled
