Kaolin is an inorganic non-metallic mixture. Calcining kaolin is to sinter kaolin in the calciner to a certain temperature and time, so as to change its physical and chemical properties to meet certain requirements. Water washed kaolin is the best raw material for producing high-grade porcelain. After deep processing and modification, the product can become…
With the large-scale mining of gold, the easily leachable gold resources are gradually exhausted, and the refractory gold will become the main resource of gold industry in the future. According to statistics, about 1 / 3 of the world’s total gold output is produced from refractory gold mines. Among the proven gold reserves in China,…
The color of pure quartz sand is generally white, opaque or semi transparent or transparent, but we will also see black impurities other than quartz in quartz sand. These black impurities cannot be completely removed in the pickling process of quartz sand. If there are too many black impurities, the quality of finished quartz sand…
In the process of beneficiation, the purpose of classification operation is to effectively separate the coarse and fine particles, avoid over crushing of fine minerals, and make the coarse minerals return to the mill as return sand for regrinding. Its operation effect will directly affect the production capacity of grinding equipment, finished product effect and…
“Waste rock is a resource misplaced”. After processing, waste rock can be called high-quality gravel aggregate. If we want to realize “turning waste into treasure”, we need to adopt a feasible processing scheme to comprehensively recycle it. For the use of mine waste rock and tailings, many people know that they can be used to…
Limestone is abbreviated as limestone. Its chemical composition is mainly calcium carbonate, which is easy to dissolve. It is the main material for burning lime and cement, as well as the flux for ironmaking and steelmaking. Generally, it is crushed for subsequent use. The output of aggregate production line ranges from several hundred It can…
01. Tungsten minerals and their floatability Tungsten minerals with industrial value mainly include scheelite and wolframite. The beneficiation methods of tungsten ores mainly include gravity separation, magnetic separation, spot separation and flotation. Flotation is commonly used for the recovery of fine scheelite, WOLFRAMITE SLIME and symbiotic sulfide ore. 02. Flotation process of tungsten ore Ⅰ….
06 Elbow plate replacement In the production process, because of the large stress, the elbow plate often has cracks or even cracks, and what’s more, there will be transverse faults, which need to be replaced in time. When replacing, first take out 2-3 pieces of steel plates as adjusting the size of the blanking port,…
Because the broken stones are of high hardness and large particle size, the jaw crusher has high working strength and bad working environment. In the case of long-term use, stone on the crusher components caused by wear is very large, and even can reduce the service life of jaw crusher, and will inevitably fail. How…
Ⅰ. What is the expression method of grinding fineness?The fineness of grinding products is usually screened by the 200 mesh sieve of “standard sieve”, which is expressed by the percentage of the amount under sieve in the total amount of products (“mesh” is the number of sieve holes in each inch of sieve layer, and…
