Quartz powder and silica sand are the two most popular industrial raw materials used in many fields. Although they are all made of quartz, their purposes and characteristics are different. Many mining sites use high cost high-frequency screens to screen quartz powder and silica sand, so this article will explain how high-frequency screens improve screening efficiency when screening aggregates.
Key Features of Quartz Powder
- High Purity: It is chemically very stable, has a low Moh’s hardness and is very pure with minimal trace impurities, thus ideal for application in the glass and electronics industry.
- Fine Particle Size: Its fine texture makes it ideal for operation in precision applications.
- Durability: Quartz powder is very tough and chemically inert, and gives strength to the materials with which it is mixed.
Key Features of Silica Sand
- Coarser Texture: Silica sand has a bigger size of particles compared to the size of particles of quartz powder.
- High Melting Point: Due to its thermal stability it is applied in heat-resistant applications.
The characteristics of the two materials not only require the sieve plate to have super strong wear resistance, but also to accept uniform sieving degree.Polyurethane high-frequency fine screen has the advantages of light weight, high screening efficiency, high screening accuracy, large processing capacity, compact and reasonable structure, easy installation and replacement, and low power consumption of the screening machine.
The high-frequency screen we provide can match the screening requirements of silica sand and quartz sand from several aspects:
- Structural characteristics
(1) High frequency and low amplitude (60Hz, 0.8mm) are used, as well as positive inclination and large inclination screen surfaces (>30 °), which have high transportation capacity.
(2) The screening machine has three independent screening surfaces, which are fed separately. While maintaining the same screening efficiency, its processing capacity is 1.5 times greater than that of a single point feeding sieve.
(3) The structure of the sieve chute is unique, which does not hinder the sieve water from the middle and discharge end sieve surfaces from falling into the sieve water funnel of the sieve machine.
(4) The exciter is installed on the upper part of the sieve box and can generate a 60Hz excitation force. The sandwich screen woven with metal wire is less prone to clogging and reduces cleaning frequency.
Mesh opening rate characteristics
HUATAO’s high-frequency fine screen has a pore opening rate of 28% to 40%, which can replace imported products.
Classification efficiency characteristics
The grading (separation) particle size of high-frequency fine screening is usually 0.045-0.71mm, and the grading efficiency is 60% -75%.
Matching machine characteristics
Suit for : Derrick stack sizer TH48-30, TH48-42, TH56-42,TH56-30 Etc.
Prolong lifetime characteristics
It has a lifespan 3-8 times longer than stainless steel mesh, effectively reducing the frequency of mesh replacement, saving time, and increasing production.
Conclusion
The use of high-frequency screening can not only accept the rough surface friction of silica sand and quartz sand, but also flexibly screen the phenomenon of powder clogging. Reducing production costs while ensuring screening quality.
