The technical standard of silica sand as raw material for producing artificial quartz slabs is very high, in addition to on the purity and particle size range it has high standard, on the whiteness of silica sand it has high standards as well. Some high-grade quartz raw materials can be processed in a series of processes such as crushing, sand making, iron removal, impurity removal, flotation, pickling, to produce qualified silica sand for quartz slabs. According to the characteristics of silica sand for quartz slabs. Sinonine develops appropriate solutions, which use advanced production technology to ensure the full use of silica sand resources and produce qualified products, at the same time fully considers reducing the cost of production line investment and operation, and environmental protection issues.
The technical process of slab sand processing
For quartz raw materials with high whiteness, through crushing, ball mill, magnetic separation, classifying, dewatering and drying the qualified silica sand can be obtained. For quartz sand containing a certain percentage of variegated impurities, in addition to need the above processes, it needs pickling process to remove the brown oxide wrapped on the surface of the quartz sand. Sinonine adopts enclosed acid pickling equipment in leching process. The excellent leching effect can be obtained, and at the same time it avoids the pollution problem and widely recognized by the market at present. Features of slab sand processing
1. High productivity of the production line, which can reach more than 95%;
2. Simple structure of production line equipment, easy to maintain and operate;
3. No secondary pollution in the production process, ensuring high purity of the product;
4. Adopt environmental treatment measures to protect the environment;
5. The product has uniform particle size, round shape and no dust.
The production line adopts acid pickling method to produce quartz sand for making slabs, and produces 20ton of high purity quartz sand per hour. After crushing and grinding, the quartz sand is first graded, and the quartz sand with appropriate particle size are pickling to remove the impurities, and the products after acid pickling are dried by dewatering and rotary drier to obtain the final product.
Congo 10tph quartz sand dry type production line
The production line adopts the dry process to produce quartz sand, dry quartz stone is crushed and fed into dry mill to grind to appropriate particle size, and then through the dry type magnetic separator to remove iron in quartz sand, and then transported to the vibrating screen for screening, big size material return to the sand making system to regrind, under each layer of the screen is the quartz sand of different particle size range. The finished product is sold in packaging. The whole production line adopts dry method, which can effectively remove iron and improve the purity of quartz sand.
Sinonine can provide turkey service for sand production to produce glass sand,frac sand,high purity sand etc.We are the first and only company in China that can provide the turnkey project service- EPC service for quartz/silica sand processing plant. We can provide quartz/silica sand production equipment with high cost-effective..
Acid pickling technology of quartz sand is SINONINE strengths, the production line is reasonable design. Preliminary research to explore the residence time and acid concentration of acid pickling solution, along with the appropriate equipment, the actual production operation has achieved the desired effect. At present, the quartz sand produced has high whiteness and purity, obtained user's consistent high praise.
