Oilfield service companies fracture a well involving pumping a fracturing fluid containing proppant into a well and into an oil or gas reservoir generally using high rate and pressure. Pumping continues until fractures are initiated and desired fracture geometry is achieved. The proppants, which are

Fluorite powder is a powdery material formed from fluorite after grinding, flotation, dehydration and drying. It can be divided into four grades according to different uses, namely metallurgical grade, glass-ceramic grade, acid grade (chemical grade) and optical grade.

The formation of cenosphere involves four steps, namely decomposition, sintering, melting and cooling1. Coal-fired power plants grind coal into pulverized coal and spray it into the furnace of power generation boiler to make it suspend for combustion.2. Most of the combustible components of coal (ca

Because the brown corundum contains Fe (iron), the quality of brown corundum can be differentiated by color. The color of brown corundum is usually brown and transparent. The color of brown corundum with high aluminum content is lighter, and the transparency of shiny brown corundum in the sun is ver

1. Crystal structure: the advantage of many crystal structural planes will increase its effect of adsorbing impurities；2. Major proportion: When the sewage treatment tank overflows, the garnet filter material will hardly flow out；3. Chemical stability: high acid and alkali resistance, very suitable

According to the classification of use, bauxite has the following types:① Metallurgical grade bauxite: refers to bauxite used for refining metal aluminum or smelting aluminum oxide;② Grinding grade bauxite: mainly used for producing high-alumina cement and various abrasives and abrasive tools (AL203

Bauxite is mainly used for refractories, and its fire resistance depends on its chemical composition. The content of Al2O3 in bauxite, sintering temperature, TiO2, FeO3 and other impurities have a great impact on the coating.In addition, the particle size and size distribution of bauxite are also im

River garnet sand is formed after a long time of impact, so its grain edge surface is more rounded, less damage to the material. Mixed with very high pressure water, garnet is used to cut steel and other materials in water jets. It can meet the needs of high cutting speed and smooth cutting surface

High quality alluvial garnet does not contain any fracture lines that weaken the inherent garnet grain crushed.A steady flow of garnet abrasives to the focusing tube that is free from blockages allows uninterrupted production without downtime resulting in optimum efficiency and lowest production cos

The bauxite is calcined at high temperature and baked at low temperature, which ensures the refractoriness and toughness of the product. The bauxite is strictly checked before processing to remove inferior and impurity. The product has the advantages of high alumina content and low sulfur and phosph
