quartz crushing


Quartzite is a non-metallic mineral, hard, wear-resistant, and chemically stable. Its main mineral component is silicon dioxide (SiO2), which is also a common silicate mineral with a hardness of 7. Quartz is widely used in industrial production such as glass, foundry, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, water treatment filter material, construction, chemical industry, abrasives, etc.

quartz crushing flow

Currently in the market, the commonly used specifications of quartz sand are 0.5-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh and other specifications. The above specifications include finished sand, finished crushed stone, and finished powder. Different specifications require different processing techniques, process design and equipment configuration.
The overall process of the quartz sand production line is: (silo) → feeder → jaw crusher (optional) → impact crusher or cone crusher → vibrating screen → sand making machine → sand washing machine ( optional) → finished sand.

quartz crushing process

The quartz sand making process is divided into three stages: coarse & fine crushing, sand making & screening, and sand washing & recycling.

The first stage: coarse & fine crushing
The materials are uniformly fed by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing. After the coarse crushed materials are screened by the vibrating screen, they are conveyed by the belt conveyor to the cone crusher for medium and fine crushing.

The second stage: sand making & screening
The crushed materials are transported by the belt conveyor to the sand making machine for fine crushing. The fine crushed materials are then screened for coarse sand, medium sand, fine sand and other specifications through a circular vibrating screen.

The third stage: sand washing & recycling
For those with strict requirements on the powder content of sand, a sand washing machine can be installed behind the fine sand, and the sewage discharged from the sand washing machine can be recycled through the fine sand recovery device. On the one hand, it can reduce environmental pollution and increase the sand production output.


1. The flow of the quartz stone crushing line is: (silo) → vibrating feeder → (jaw crusher) → cone crusher → vibrating screen → finished crushed stone (using several layers of vibrating screens, you can get several size of the finished product).

2. The flow of the quartz sand grinding production line is roughly as follows: (silo) → vibrating feeder → jaw crusher → bucket elevator → electromagnetic vibration feeder → quartz sand mill → finished powder (using different grinding powder The equipment can get powder of different fineness).

Products Recommended

Jaw crusher

Jaw crusher can crush hard quartz. The jaw crusher has high compressive resistance, wide feed size range, no dead zone in the crushing cavity, high output and crushing efficiency.

cone crusher

The cone crusher maximum feed size is 300mm. There is no requirement for hardness, and an overload protection device is installed, so the operation process is very safe and stable.

VSI sand maker

Sand making machine is commonly used for fine crushing and shaping of quartzs. Product have good cubic shape,uniform grain size.

Sand Washer

The sand washing machine is used to clean the quartz particles after sand making. Small amount of fine sand loss, less water consumption, and good cleaning effect.
