1.Pure and good quality
2.We are manufactory
3.Various sizes for different uses
4.Long life cycle for using
We are the professinal manufacture of quartz sand . the quartz sand can be used for both of water treatment and refractory . but using different field must with different specification . of cuase with different prices.
As bellow is the specification of quartz sand used to be refractory

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.
