Silica Sand Processing Plant

Quartz sand processing plant is used to produce all kinds of quartz sand products, improve the content of SiO2, reduce the content of impurities, to meet the needs of glass, casting, electronics, chemical, construction, filler and other industries.

The raw quartz stone or quartz sand needs to be purified to remove impurities, such as iron, aluminum oxide, mica and other harmful substances, so as to obtain high purity quartz sand. The quartz sand processed by the quartz sand production line has a SiO2 content of more than 99.9% or higher, and the iron content should be controlled at 0.01%(100ppm) or lower, so as to meet different industrial uses.

Silica sand processing plant technical process

In the quartz sand production line process, the raw ore is crushed and screened to remove impurities, and then washed, classified, scrubbed to further remove impurities from quartz sand, classified into requested particle size, and then through magnetic separation, gravity separation, flotation and other processes to remove embedded metal and non-metallic impurities, and finally through washing and desliming to obtain high purity quartz sand.

Grinding and classifying

The common formation of quartz ore is generally quartz lump and sandy quartz, the quartz lump needs to be crushed down to 25mm and then to be ground to reach a certain particle size by a rod mill, and then enter the hydraulic classifier to separate out a desired particle size range. The sandy quartz needs to be screened first to remove impurities such as soil and organic matter, and then enter the hydraulic classifier to separate out a desired particle size range. The classified quartz sand enters the next processing operation.

First washing and desliming

The processed quartz sand slurry can be first washed and deslimed in the desliming cone to remove some impurities, and at the same time, the sand slurry is dewatered to make the concentration of quartz sand slurry reach 60%-70%, be prepared for the subsequent scrubbing operation.

Attrition scrubbing

The prepared quartz sand slurry is sent to the scrubbing machine for scrubbing. After continuous scrubbing, the soil and impurities covering the surface of the quartz sand are disassociated from the quartz sand, and then enter the washing operation for further treatment.

Second washing and desliming

After scrubbing, the impurities and quartz sand have been disassociated, impurities exist in the surface of quartz sand and slurry, go through the desliming cone to remove soil and impurities, the purity of quartz sand is further improved.

Quartz sand magnetic separation

There are various of ferric and other magnetic impurities in the washed quartz sand, and the strong magnetic and weak magnetic ferric substances in the quartz sand are removed by the drum magnetic separator and the high gradient magnetic separator in the magnetic separation system.

Quartz sand gravity separation

There are some harmful heavy mineral impurities in some quartz sand, which need to be gravity sorted through spiral chute to remove the heavy mineral impurities.

Quartz sand flotation

There is still a part of iron, aluminum, mica, feldspar and other impurities in the processed quartz sand, the use of quartz sand flotation machine, through the flotation process, adding appropriate flotation agents, these impurities can be effectively removed, so as to increase the SiO2 content, obtain higher purity of quartz sand.

Washing and dewatering

After flotation, quartz sand concentrate can be dewatered by spiral sand washer or dewatering screen or press filter to obtain the final high-purity quartz sand, and its SiO2 content can reach more than 99.9%.

Other processes

According to the actual market demand, the acid pickling, acid scrubbing, alkaline washing, high temperature calcination and other processes can be deployed in the quartz sand production line to further improve the purity and whiteness of quartz sand to meet the different needs of various industries. The purified quartz sand product can also be dried by the quartz sand dryer, or further ground into different fineness of silica powder.

case 1:

Huangshan annual output of 400,000 tons quartz sand washing production line

The production line produces quartz sand products used in a variety of industries, including high purity quartz sand for high-end glass and for manufacturing quartz crucible. The project technical requirements are high, Sinonine demonstrated each process of the final solution and obtained the optimal technical process through experiment and verification. The project has an annual output of 400,000 tons of quartz sand, and the products sell well. This project is a representative project of Sinonine EPC service, which typical demonstrates Sinonine's technical advantages and turnkey service ability. The advanced technical design, high-quality equipment, cost-effective solution and efficient project operation mode are highly recognized by customers.

case 2:

Mongolia  450,000 tons per year glass quartz sand production line

The raw material of this production line is massive quartz stone. After crushing, screening and grinding, it enters into the classifying system for classification, and then the iron material is removed by magnetic separation and other processes. Finally, the glass quartz sand with higher purity is obtained after dewatering.The production scale of this production line is large, the product quality is very high, the product sells very well. 

Compared with the local quartz sand production line, Sinonine provides more comprehensive product details, and the production cycle is also very short. Although the delivery took some time, it is still much faster than the local procurement. In addition, the price is really affordable. I am optimistic about the overall prospect of Sinonine, and I hope they can come to visit us more. The market here is very large.
