Silica sand is more and more widely used as proppant in oil
fracturing. Silica sand is processed through a series of technical
processes to obtain silica sand that meets the requirements of oil
proppant. Conventional white sand includes 20-40 mesh, 40-70 mesh,
70-120 mesh, etc., meeting the needs of different stages. The raw
materials of silica sand are processed by means of impurity
removal, classification and dewatering to obtain silica sand
products of different specifications.
The technical process of White Sand or Cristobalite Washing
Processing Line
By forcing attrition scrubber to remove the impurities wrapped on
the surface of the silica sand, then by sand washing machine to
remove impurities, the pure silica sand shall be classified by
hydraulic classifier and hindered settling machine to obtain white
sand products suitable for requirements of different particle size
range, finally after dewatering process the qualified dry white
sand products shall be obtained.
Features of White Sand or Cristobalite Washing Processing Line
1. The production line has strong applicability and can be applied
to all kinds of silica sand;
2. Use strong scrubbing process to remove impurities;
3. The production line has high efficiency and can be automatic
controlled;
4. Strict particle size control and automatic adjustment;
5. The product has uniform size and intact shape without damage.
