The season of continuous spring rain will still have a serious impact on the production of quartz sand.
In the sand washing plant, if we want to produce high-purity quartz sand, we need to choose the right raw materials, so how to determine the raw materials of high-purity quartz sand?
Due to its superior properties, spherical quartz powder is widely used in high-tech fields such as integrated circuit copper clad laminate, epoxy plastic sealant, aerospace, fine chemical industry and daily cosmetics.
Therefore, most of the colored quartz sands we see on the market are artificially dyed.
ICP detection technology is an important support and component of high purity quartz technology, which has not only practical significance but also theoretical significance to promote the development of high purity quartz technology in China
It is necessary to strengthen the mineralogy, petrology and mineralogy of high-purity quartz mineral resources, focus on the process mineralogy characteristics of raw materials, such as chemical composition, useful minerals (quartz), harmful
The processing technology of high purity quartz sand washing plant usually includes complex processes such as calcination, water quenching, classification, magnetic separation, flotation, acid leaching, cleaning and chlorination roasting.
The processing technology of high-purity quartz sand mainly includes classification, scrubbing, chemical acid leaching, flotation, gravity separation, magnetic separation, chlorination roasting and microbial leaching.
Ultra white glass is a kind of ultra transparent glass, also known as low iron glass, colorless glass, high transparent glass, etc.
Most of the hydraulic graders in sand washing plants adopt the automatic control system, which has achieved good results.
After years of application in sand washing plant, the hydraulic classifier has achieved good economic and social benefits.
Natural quartz sand needs to be treated by fracturing sand washing plant before it can become qualified fracturing quartz sand.
Fracturing sand washing plant is generally divided into five stages, namely sand mining stage, sand pre screening stage, sand washing classification stage, fine sand drying stage and finished product screening and packaging stage.
Sinonine has developed a centrifugal dehydrator, which can remove the acid water of the acid washed quartz sand quickly, and can also be used for the conventional dehydration of quartz sand.
In order to improve the efficiency of iron removal, the magnetic separation of quartz sand with particle size of more than 60 mesh and less than 180 mesh is strengthened, which can effectively reduce the content of iron impurities in quartz
There are few raw materials that can directly produce high-purity silica powder, so it is very important to prepare high-purity silica powder from quartz sandstone for the development and utilization of quartz sandstone resources.
The main quality indexes of transparent quartz glass are purity and bubbles, which require quartz sand to have very low impurity and gas content.
The main method to remove crystal lattice impurities of quartz sand is chlorination roasting process
In the raw quartz sand, the pure quartz sand is white or milky white, and the color of iron bearing impurities or gangue minerals is yellowish, light yellow or light brown and gray. The color difference between quartz sand and iron bearing i
The main drying machines of quartz sand are rotary dryer, hot air convection dryer, fluidized bed dryer, infrared dryer and microwave dryer.
