Silica Beneficiation Plant
Silica may be used in lump form, as sand, as a finely ground powder, and as silica flour. Primary crushing of lump silica is readily accomplished by jaw and cone crushers, and secondary crushing is done by hammer or impact type mills. Further reduction to sand size may be accomplished by roll crusher or rod mill, and to flour size or finer by ball, vibratory or jet-milling, or by attrition grinding in a “stirred” ball mill using small ceramic pebbles as grinding media.
Silica Mining Equipment
Silica sand mining the processing technology used in is very important. This technology including dry wet process, sometimes, craft combination, in order to obtain satisfactory products. In decision-making process common quartz sand, jaw crusher is mainly used for crusher, then go through the secondary crushing.
Following primary and secondary crushing, lump quartz, sandstone and quartzite for use as flux in the manufacture of silicon and ferrosilicon, etc., must be screened to meet size specifications. Screening may result in minor upgrading through the removal of impure fines, but such material is essentially used as quarried with no beneficiation apart from sizing.

Further reduction of the silica to a specific size, e.g., minus 850 μm to plus 150 μm, must be carefully carried out to avoid introducing extraneous impurities such as mill iron and other contaminants, and care must be exercised to avoid over-grinding. Whole unfractured grains are preferred in foundry moulding, and fines are detrimental in both foundry and glass sand applications. Over-grinding is more difficult to control when the starting material is quartz or quartzite as they do not possess a well-defined granular structure such as when crushing a more weakly cemented friable sandstone. The choice of grinding unit is also important; for example, impact mills produce more fractured grains and fines than jaw, cone, or roll crushers.
Silica beneficiation often adopts magnetic separation and flotation separation. Magnetic separation can separate iron and other magnetic materials from silica sand mixture. Through several times flotation, these silica sand will become wet concrete. Finally, the dryer dried them, we will get final products. In silica sand beneficiation plant, the equipments used are jaw crusher, cone crusher, Vibrating Screen, magnetic separator, flotation separator, dryer, bucket and other related machines.
