Embodiment 1

[0020] The quartz rock ore produced in Liaoning is selected. The surface of the large quartz raw material has been impregnated with iron for a long time, and a layer of iron oxide film is formed on the surface of the ore, but the texture inside the ore body is better and the color is milky white.

[0021] The invention provides a method for producing quartz sand for artificial quartz stone, comprising the following steps:

[0022] S1. Use a water jet cleaning machine to clean the quartz ore raw material, and set the cleaning pressure to 180MPa to remove the iron oxide film layer on the surface of the quartz ore raw material;

[0023] S2. Crushing the cleaned quartz ore raw material with a crusher, first coarsely crushing it with a jaw crusher, and then crushing it with a cone crusher to obtain quartz fragments below 20mm;

[0024] S3, using an alumina ceramic lined ball mill to grind the quartz fragments into quartz sand below 2 mesh;

[0025] S4. Send the quartz sand to a pl...

Embodiment 2

[0030] The quartzite ore produced in Inner Mongolia is selected. The ore is of good quality, milky white and translucent. There are black and blue-gray minerals in the ore, and there are obviously flesh-red feldspar minerals and light red disseminated quartz particles. There are mud on the surface of the ore. quality.

[0031] The invention provides a method for producing quartz sand for artificial quartz stone, comprising the following steps:

[0032] S1. Use a water jet cleaning machine to clean the quartz ore raw material, and set the cleaning pressure to 20MPa to remove the mud on the surface of the quartz ore raw material;

[0033] S2. Crushing the cleaned quartz ore raw material with a crusher, first coarsely crushing it with a jaw crusher, and then crushing it with a cone crusher until it reaches quartz fragments below 20mm;

[0034] S3, using an alumina ceramic lined ball mill to grind the quartz fragments into quartz sand below 4 mesh;

[0035] S4. Send the quartz s...

Abstract

The invention discloses a production method of quartz sand for artificial quartz stones. Yellow skins, scales, ferric oxide film layers and mud on the surfaces of quartz mine raw materials are removed by using a water jet cleaning machine; a traditional acid treatment process is discarded, so that the acid water drainage problem cannot be caused; the quartz mine raw materials are fed in a plate magnetic separator for magnetic separation after smashing and ball milling to remove magnetic ores in quartz mines and mechanical iron leaded in the smashing process so as to prevent rust points generated on products; variegated ore particles in the quartz sand are removed by classification and sorting; finally, the screening is performed to obtain the quartz sand accordant with the demanded particle sizes; the whole process needs no any chemical agents; the particle size control is flexible; and the production process adopts wet production to prevent the dust pollution.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a method for producing quartz sand for artificial quartz stone. Background technique [0002] Artificial quartz stone is a synthetic stone manufactured by artificial methods. It has the incomparable advantages of natural stone such as high strength, high hardness, high temperature resistance, corrosion resistance, anti-aging, easy cleaning, wear resistance, and no radiation. These advantages make artificial quartz Stone has become an upstart in the architectural decoration industry, and is widely used in cabinets, bathrooms, floors, wall decorations and home furnishing in offices and large shopping malls, and has gradually become one of the green and environmentally friendly building materials that consumers love. The demand continues to increase and there is a huge market space. [0003] The main raw materials of artificial quartz stone are quartz sand and quartz powder, which...
