Silica Sand
Silica sand can range from nearly transparent to a darker gray. It is an odorless powder that can cause irritation to the skin or eyes on contact. Inhaling silica sand will also irritate the respiratory tract. In fact, the fine particulates of silica dust from quartz rock contribute to chronic, progressive lung injury, known as silicosis. Additional physical properties include:

Molecular Weight: 60.084 g/mol
Exact Mass: 59.966756 g/mol
Boiling Point: 4046°F at 760 mm Hg
Melting Point: 3110°F

Silicon dioxide (SiO2) is a naturally occurring compound of silicon and oxygen. This is the primary compound present in silica sand, which occurs in three main crystalline varieties, including quartz, tridymite, and cristobalite. The covalent bonding of a single silicon atom with two oxygen atoms, creating linear triatomic molecules, forms SiO2. Additional chemical properties of silica sand include:

Solubility: Insoluble
Vapor Pressure: Approximately 0 mm/Hg
Heat Combustion: Noncombustible

This setup is for the silica sand process, the size range of the silica sand is 0-10mm, the main machines are as below.

Hopper + electromagnetic feeder > belt conveyor > rotary trommel screen > +0.5mm to ball mill, 0-0.5mm to spiral sand wash machine > spiral chute > slurry pump > wet plate magnetic separator > dewatering screen

Process Explanation
The hopper+electromagnetic feeder for feeding materials to the rotary trommel screen automatically, you only need to load the materials to the hopper by truck or excavator or else as you want.

The rotary trommel screen is for washing the silica sand and separating the size 0-0.5mm to the spiral sand wash machine, and +0.5mm to the ball mill.

The ball mill is for grinding the +0.5mm size to 0-0.5mm, then to the spiral sand wash machine.

The spiral sand wash machine is for washing and getting rid of the sticky clay in the silica sand, then to the spiral chute.

The slurry pump transports the clean materials to the spiral chute to separate the silica sand from other heavy materials.

The wet plate magnetic separator is for separating the magnetic minerals in the silica sand, making the silica sand purer.

The dewatering screen is for drying the silica sand and recycling the water for the machines.

The capacity for this washing plant can be customized as per request such as 10tph, 50tph,100tph, etc

Notes: If the materials are not much sticky, will not need the spiral sand wash machine, and the quantity of the machines just for your reference, will depend on your capacity.

The spiral chute will normally make two stages, the middle concentrate from the first stage spiral chute will to the second stage to concentrate again, which will make sure a higher grade and also release the workload of the magnetic separator.
