The most silica sand is made up of broken down or crushed or grinded quartz crystals or silica. The common quartz crushing plant or silica crushing plant consist of Jaw crusher, Impact crusher, Vibrating feeder, Vibrating screen and Belt conveyor. The big size quartz block are transferred to primary crusher - Jaw crusher through Vibrating feeder from hopper for first crushing, then the crushed materials are transferred to Impact crusher through Belt conveyor for secondary crushing. The materials crushed, which is silica sand, will be transferred to the Vibrating screen, and separated to different sizes. The silica sand with suitable size will be transferred to the final product pile and silica sand with unsuitable size will be transferred to the Impact crusher for re-crushing. This forms a closed and manifold cycles.

The crushed quartz sand or silica sand may be bigger than the required final size. So it must be grinded after crushed. The common quartz grinding machine or silica grinding machine is Ball mill. The Ball mill is a horizontal rotating device transmitted by the outer gear. The quarts are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the quartz. The grinded quartz are discharged through the discharging board thus the grinding process is finished. There are also other grinding machines applicable to grinding silica sand and quartz sand, such as coarse powder mill. dsmac coarse powder mill has been widely used in quarts sand, silica sand, foundry sand, fine sand and other sand abrasive industry. The grinding plant can be designed by the customers requirement.
