Quartz flour

Silica flour is finely ground silica sand that offers superior purity and very high silica content of around 98.0% or above. Silica sand mined from reserves is processed to obtain silica flour. Mined silica sand is washed, attritioned, scrubbed, hydraulically sixed using mills with sieves of various mesh sizes, and dried to obtain different sizes of silica flour.

A commonly used mesh size range for grinding silica sand is 50 mesh to 550 mesh. Silica flour ground using 200-325 mesh are highly preferred for applications such as:

– fiberglass;

– oil well cementing operations;

– sodium silicate;

– water purification;

– glass, casting, ceramics;

– fireproof materials;

– smelting ferrosilicon;

– metallurgical flux

– chemical industry and plastics;

– rubber, abrasives;

– filter materials and other industries.
