 silica sand /quartz sand

Our factory adopts the natural good quartz as raw material, it is broken mechanically, grinding and pressing, washing and selecting, vibrating to divide and other producing techniques, in this way, it can efficiently protect the quartz’s natural structure, so it delays its usage cycle. It collates quickly and efficiently, and its water quality is steady, never jams nor clotting. Its usage cycle is longer than sea sand.

Quartz sand filtration has been widely and massy used for the water treatment filtration. It is suitable for single and double layer filtration poor. Our water solution chooses the natural screen for raw material, process by washing, fragmentation and filtrate. Characteristic: no impurity, high rigidity, chemical tranquilization, long life cycle for using. we have product available and can shipment the product according to your need.
