High purity quartz sand production line, quartz sand production equipment, quartz sand beneficiation equipment

High purity quartz sand production line, quartz sand production equipment, quartz sand beneficiation equipment is a complete set of production line equipment designed and manufactured by our company. Quartz sand as a domestic and foreign mainstream glass raw material ore, belongs to a kind of feldspar, its processing methods and production line process affects its economic value of how much, high purity quartz sand as a strategic product, in the national economy plays an increasingly important role, to get high purity quartz sand, it is necessary to use the quartz sand production line as well as quartz beneficiation equipment, the following we will speak in detail about how to produce high purity quartz sand. Here we will talk about how to produce high purity quartz sand in detail.

I. Quartz sand production line turns quartz stone into sand

Quartz sand production line is a kind of special equipment specialized in producing construction sand 

and stone material with 50% energy saving than traditional sand making machine. It can make all kinds

 of quartz stone into construction sand with various granularity which is far better than natural sand.

Quartz sand production line working principle

Rough crushing--Fine crushing--Screening--Sand making--Sand washing

First of all, the quartz sand material is crushed initially, then the coarse material is crushed further by

 the belt conveyor to the fine crusher, and the finely crushed stone is screened by the vibrating screen 

to separate the two kinds of stones, and the quartz sand that meets the feed size of the quartz sand 

making machine is fed into the sand making machine to make sand, and the other part of the returned

 material is crushed again. The other part of the return material will be re-crushed. After that, it will be 

washed by the wheel bucket sand washer and made into finished sand, and the final output will meet

 the requirements of the product particle size.

Second, the quartz sand cleaning, purification

Quartz sand, also known as silica sand, is a common non-metallic mineral raw materials, due to the natural quartz minerals containing more types of impurities, the purity of the mineral itself is very low, so it is necessary to use the beneficiation process for its beneficiation and purification operations. High-purity and ultra-high-purity quartz sand made through beneficiation and purification has been widely used in aerospace, atomic energy technology and other high-tech fields.

Quartz sand production and purification of a full set of equipment

Crushing and screening stage: coarse crushing PE jaw crusher, fine crushing PEX jaw crusher, cone 

crusher, feeder, circular vibrating screen and so on.

Grinding and grading stage: ball mill qmj.html, spiral classifier and so on.

Beneficiation and purification stage: quartz sand magnetic separator, flotation machine, mixing dru etc..

Quartz sand purification process currently has many kinds of domestic, but basically can not be 

separated from the scope of the physical and chemical methods. Because the process is more, each 

production enterprise in the face of the process of choice when the conditions are also different, here 

we only hint about the quartz sand used in the beneficiation process method. Simply put, it is the use 

of mineral processing to solve the problem of quartz sand purification. Commonly used quartz sand 

magnetic separation and quartz sand flotation methods.

1、Quartz sand magnetic separation purification

Magnetic separation process for quartz sand can largely remove weak magnetic impurity minerals 

such as hematite, limonite and black mica, including congenial particles. Quartz sand magnetic 

separator is the main equipment for processing high purity quartz sand and selected quartz sand, 

the equipment has good purification effect, high sorting precision and high sales.

Magnetic separation and purification process

When the quartz sand magnetic separator works, the cylinder of the magnetic separator rotates, and 

the magnetic system does not move. The finely ground slurry enters the sorting tank through the 

feeding box, in which the magnetic ore particles are magnetized under the action of uneven magnetic

 field, attracted by the magnetic field, sucked on the surface of the cylinder and rotate with the cylinder. Magnetic ore particles transported to the magnetic field exit, due to the weakening of magnetism coupled with the impact of the wash water flushing, and disengaged from the magnetic attraction and be discharged into the concentrate. Non-magnetic minerals are not attracted by the magnetic field, stay in the slurry with the flow of ore discharged as tailings.

2, quartz sand flotation purification

Flotation is another commonly used quartz sand mineral sorting and purification process, in the 

sorting process using the hydrophobicity of the mineral surface differences to achieve the purpose 

of mineral separation.

Flotation purification process

In the raw ore, add trapping agent, adjusting agent, foaming agent and other flotation chemicals, in 

which the trapping agent will selectively adsorbed on the surface of the impurity particles to increase 

its hydrophobicity, hydrophobic particles along with the movement of the slurry, when it meets with 

the bubbles in the slurry will be adsorbed on the surface of the bubbles and with the upward flotation, 

and then by the scraper of the flotation machine fxj.html hang out. High purity quartz sand production 

line, quartz sand production equipment, quartz sand beneficiation equipment is introduced here for

 the time being, for the production line process and equipment, mainly according to the nature of the

 ore and customer demand and design, the above program is only for reference, if you have a question

 about this want to consult, you can call our service hotline.
