New Design Deep Purification Silica Sand Purification Equipment

Product Description

Product Description

The High Purity Silica Sand Processing

   mainly involves purification, removing trace impurities by magnetic separation, flotation and high temperature purification. Specific silica sand size can be achieved by crushing, grinding and screen processes.

Main Machines

Name	Model	Purpose/Function
Crushing	Jaw Crusher	It applies multiple crushing actions (extrusion, kneading, grinding) to materials, reducing them from large to small sizes. The materials fall gradually until discharged through the outlet.
Ore Washing	Drum Ore Washer	The motor drives the drum to rotate at a fixed speed via a transmission device. As the drum rotates, ores move with it; since the drum is inclined, ores gradually travel from the feed inlet to the discharge outlet inside. A built-in high-pressure flushing pipe removes mud and fine powder from the ore surface.
Calcination	Cclcinting Kiln	It converts electrical energy into heat via elements (e.g., resistance wires, carbon rods) to raise the furnace temperature for roasting materials. The furnace tube is a rotatable cylinder: materials enter one end, tumble inside as the furnace rotates, and move toward the other end.
Sand Making	Impact Sand Maker	Materials enter the machine through the feed inlet and are first accelerated by a high-speed rotating impeller (mounted on the rotor). As the impeller spins, materials gain high speed, then are thrown out to strike the cavity lining and other materials at extreme velocity, achieving crushing.
Screening	Swing Screen	It screens materials via eccentric oscillation. A special drive makes the screen box perform near-planar circular, elliptical, or reciprocating linear motion. This motion lets materials continuously change direction and speed on the screen surface.
Magnetic Separation	Magnetic Separator	It uses a magnetic field (generated by energized coils in air) for separation, mainly sorting strong magnetic substances, fine weak magnetic substances, and mechanical iron from quartz sand.
Reaction	Double-Cone High-Temperature Reactor	The reactor’s double-cone body ensures good material mixing and tumbling, promoting uniform reactions. Compared to traditional cylindrical reactors, the double-cone structure reduces dead corners during stirring/reaction, boosting efficiency and product quality.
Flotation	Centrifugal Flotation Machine	It uses centrifugal force to enhance flotation. After ore pulp and reagents enter, mineral particles and bubbles are thrown to the rotor’s edge at high speed under the centrifugal force from the rotating rotor.
Dewatering	Centrifugal Dewatering Machine	It achieves solid-liquid separation using centrifugal force. When wet materials are placed in the high-speed rotating drum, denser solid particles are thrown to the drum’s inner wall and accumulate there, while water (lower density) is discharged through the drainage holes or other devices on the drum wall.
Sand Roasting	Electric Heating Sand Roasting Furnace	It converts electrical energy into heat via heating elements (e.g., resistance wires, silicon carbide rods) to raise the furnace temperature for roasting materials. The furnace tube is a rotatable cylinder: materials enter one end, tumble inside as the furnace rotates, and move toward the other end.

FAQ

Q: How big is your factory?

    How long have your company been providing complete silica sand production line construction service?

A: Started in year 2012 with just one factory producing crushing machines, we have expanded into 4 work shops,31,300 squre meters, office  3200 squre meters, 110 workers.

     Our rapid development was right after we extended our business into whole silica sand production line construction in year 2017.

 

Q: What Information is needed to conduct the production line construction evaluation? 

A:1). Please provide your plant information, site, size, current facilities etc.

   2). Please provide your stone samples or stone parameters (size, element content) and your target parameters of the processed sand (purity,  trace element content)?

   3). What is your handling capacity(tons per hour) ?

Q: Can we send the rock samples to your company for you to conduct the mineral processing tests?

A: Yes, we have in-house lab and professional team to perform the test, and we can provide professional processing approach based on the test result.
