Silica sand occupies great role in the industry development and then the silica sand manufacturing process will help customers excavate much more silica sand. Depending on years' abundant production experience and high technology, We has manufactured the advanced silica sand manufacturing process machine to satisfy the production needs. Here is the detailed manufacturing process and the related machines.

Silica Sand Manufacturing Process

The raw silica sand materials will have the crushing, grinding and beneficiation process. It maybe use the sand making machine, jaw crusher, cone crusher, impact crusher, ball mill, Raymond mill and vertical mill, sand washing machine etc. Crushing plants are usually composed of a primary crushing unit and a secondary crusher with a screen plant. Crushing plants are powered by either a large diesel engine, or by a generator. The shot rock is picked up by front end loaders from the blast area and carried to the primary crusher. The primary crusher breaks the shot rock into what is referred to as breaker run. Breaker run is conveyed to the secondary crusher where it is further broken down. The resulting material is fed to a screen plant where it is sorted by size. Smaller particles of a targeted size are carried away to stockpiles. Larger particles are recycled within the plant to the secondary crusher and screens until they have reached the desired size.

The sand is washed to remove fine particles. Washing is done by spraying the sand with water as it is carried over a vibrating screen. The fine particles are washed off the sand and the coarse particles are carried along the screen by the vibration. Some processing operations also use what is called an upflow clarifier to wash the sand. An upflow clarifier is essentially a tank where water and sand are continuously directed into the tank. The water washes the sand and the overflow water along with the fines overflow the tank while the washed sand falls by gravity to the bottom of the tank and is sent for further processing.
