Silica sand classification

The regular specifications of silica sand are: 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80mesh, 100-120 mesh, 200 mesh, 325 mesh, SiO2 > 99-99.5% Fe2O3 less than 0.02-0.015%.

The silica sand raw material is usually will contain sticky clay, Kaolin clay, ilmenite, Hematite, Iron, and other magnetic minerals. The silica sand color in raw material maybe white, yellow, brown, etc.

Silica sand Application

Silicon sand is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, machinery, electronics, chemical, plastic, abrasive, rubber, aerospace and other industries. Another important use of silica sand is the filter and filter used for water treatment.

1) Glass: flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and special glass for anti ray

2) Ceramics and refractories: porcelain materials and glazes, high silica bricks, ordinary silica bricks and silicon carbide raw materials.

3) Metallurgy: raw materials or additives and fluxes of silicon metal, ferrosilicon alloy and silicon aluminum alloy.

4) Construction: concrete, cementitious material, road building material, artificial marble, cement physical property test material (namely cement standard sand)

5) Chemical: silicon compound and water glass and other raw materials, sulphuric acid tower filling, amorphous silica powder.

6) Machinery: the main raw materials for casting sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, abrasive cloth, etc.)

7) Electronics: high purity metal silicon, optical fiber for communication, etc.

8) Rubber and plastics: fillers (increase wear resistance)

9) Aeronautics and Astronautics: its internal molecular chain structure, crystal shape and lattice change law, with high-temperature resistance, low thermal expansion coefficient, corrosion resistance, high insulation, piezoelectric effect, resonance effect and its unique optical properties.

Silica sand process flow

In summary
Feeding->washing -> primary sieving -> gravity separation to remove heavy minerals -> refining process to remove magnetic minerals -> Sieving out requested size silica sand -> drying -> packing

1. Silica sand Feeding
Use vibration feeding machine, feeding hopper, electromagnetic vibration feeder, belt feeder, wheel loader or excavator feed directly. It depends on process capacity and raw material conditions to choose which feeding machine.

2. Clean clay
Washing clean the clay, kaolin clay and mud in raw material, most popular silica sand washing machine are trommel scrubber, log washer, spiral washer, attrition scrubber, etc. Wash machine for sale
The silica sand washing attrition scrubber and spiral classifier washing machine are especially good washing effect for small size silica sand -3 mm. If bigger size, can consider using trommel scrubber and log washer to wash silica sand.

3. Primary Sieving to remove coarse waste sand
After washing clean the clay, then need to sieve out some bigger waste sand, the under-screen sand will go to next gravity separation machine. This sieving process can use normal vibration screen or silica sand high-frequency vibration screen. Vibrating screen details

4. Gravity separation to remove heavy minerals
It is for primary silica sand gravity separation to remove heavy minerals, such as ilmenite, hematite, iron, etc, the most common use silica sand separation machine is shaking table, spiral chute separator. It depends on the processing capacity to choose which gravity separation machine.

If a big capacity plant, usually uses spiral chute separator with bigger capacity. If a small capacity plant, usually uses shaking table to separate out silica sand.

6. Silica sand refining process removes magnetic minerals
After silica sand gravity separation, there will still some percentage magnetic minerals in silica sand, so need to remove it by magnetic separator, different magnetic minerals, will use different gauss magnetic separator, for removing iron, need 1000 gauss, for removing ilmenite and hematite, need 8000-9000 gauss. Different usage of silica sand, will request different percentages of magnetic minerals remaining in the final silica sand product.

7. Sieving out requested size silica sand
After removing magnetic minerals, will need to sieve out requested size silica sand, usually use the high frequency vibration screen, with PU screen, screen mesh size can be customized.

8. Drying
After sieving out final silica sand, then drying the sand by drying mahcine.

9. Packing
After drying the sand, use packing machine to pack final silica sand product ,then can sale. The silica sand packing machine is ton bag packing machine, can be 0.5 T, 1 T, 2 T, or 3 T per bag as requested.
