Customized High-grade Silica Sand Mining Process Line

Silica Mines

In the glass industry, silica sand is a key ingredient in the production of glass products due to its high silica content, low impurities concentration (typically Fe2O3, Al2O3, TiO2) and physical properties. As such, glass sand generally has a higher purity and a more controlled grain size compared to regular silica sand. It undergoes processing to remove impurities and achieve specific characteristics required for glass production. Glass sand is a critical component in making various types of glass, including float glass, container glass, fibreglass, and speciality glass products.

Mining the rock
Early industrialists discovered that certain deposits of more or less pure silica (SiO2) provided ideal ingredients for the manufacture of firebricks for kilns and furnaces. Hengyang Industry mainly provide machines for silica mining, better for help various industry.

Quarrying the sand
Silica sand derived from sea sand or silica stones was extracted and used in the manufacture of refractory fire bricks for the smelting industries. The silica sand was transported via tramroads to a brickworks. 

Moving the materials
Tramroads and railroads from many of these mines and quarries connected with the world.

Common specifications of silica sand are: 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh, 200 mesh, 325 mesh.

Silica Processing Mainly Include following Steps:

Feeding:

The raw material is conveyed to the primary crushing equipment through the feeder,it's usually a jaw crusher.

Crushing:

The mined silica sand (quartz sand) ore is continuously fed into the coarse jaw crusher by the vibrating feeder for primary crushing, and then the particles after primary crushing are sent to the fine jaw crusher by the belt conveyor for re-crushing, and the crushed silica sand particles are sent to the vibrating screen for screening and grading.

Sand making:

After the screening process, the quartz sand particles that meet the feeding particle size requirements of the vertical shaft impact crusher enter the sand making machine for sand making process, and those that do not meet the requirements are returned to the crusher for re-crushing.
Screening:

The qualified silica sand particles from the sand making machine are returned to the circular vibrating screen for re-screening, the materials that meet the requirements go to the next process, and the materials that do not meet the requirements are returned to the sand making machine for sand making and crushing again;

Sand washing:

The produced silica sand is sent to the sand washing machine by the belt conveyor for cleaning, and the cleaned silica sand is sent to the finished product pile.
