The purpose of lubrication management is to prevent equipment lubrication failure, reduce the loss caused by equipment overheating shutdown, save maintenance costs and reduce the replacement of parts, prolong the service life of equipment, reduce lubricant consumption and save the cost of purchasing lubricating materials. Modern mechanical equipment is developing towards the direction of high precision, high efficiency, high speed, heavy load, small, maintenance free and energy saving, which puts forward higher requirements for the friction parts of mechanical equipment.1. Fault phenomena and

Grinding machine is widely used in the grinding and processing of mineral products and materials in the fields of metallurgy, building materials, chemical industry, mining and so on. According to the fineness of the milled materials and the fineness of the discharged materials, the mills can be divided into many types, such as Raymond mill, ultra-fine mill, etc. The production efficiency of pulverizer directly affects the profits of manufacturers. We must pay more attention to the factors affecting the production efficiency of pulverizer in production. Today, Xiaobian

Nickel ore refers to the ore containing nickel element or nickel compound, which can be beneficiated into nickel concentrate or nickel ore sand with high nickel grade. Nickel concentrate can become refined nickel and nickel products only after smelting Commission. The content of nickel ore in the earth’s crust is 0.018%. The main minerals of nickel ore include nickel pyrite [(Ni, Fe) 9s8], silicon magnesium nickel ore [(Ni, Mg) SiO3 · nH2O], needle nickel ore or yellow nickel ore (NIS), red nickel ore (Nias), etc. Nickel is

Barite is the most common mineral of barium, and its component is barium sulfate. It occurs in low-temperature hydrothermal veins, such as quartz barite veins and fluorite barite veins, and often coexists with galena, sphalerite, chalcopyrite, cinnabar, etc. Barite deposits in Hunan, Guangxi, Qinghai and Jiangxi are mostly huge hydrothermal single mineral veins. Barite can also occur in sedimentary rocks, appearing as nodules, and mostly exists in sedimentary manganese deposits and argillaceous and sandy sedimentary rocks in shallow sea. In the residual clay overburden of weathered residual

In recent years, energy conservation and environmental protection has always been the most important task in today’s society, and the stacking and transportation problems caused by construction waste as abandoned waste, as well as the environmental pollution problems caused by the scattering and flying dust and sand in the process of cleaning, transportation and stacking, are regarded as the burden of urban development. In order to create a road of rebirth for construction waste, we can only rectify the disorderly stacking of construction waste from the source

Silicon carbide is a kind of carbide, which was accidentally discovered by American Acheson during the diamond experiment in 1891. There is little natural silicon carbide and most of it is man-made. It usually takes quartz and petroleum coke as raw materials, auxiliary recycled materials and waste materials, and after grinding and other processes, it becomes a furnace charge with reasonable ratio and appropriate particle size (in order to adjust the air permeability of the charge, it is necessary to add an appropriate amount of wood chips

1、 Function of vertical mill (1) The function of the vertical mill is the most important function of the vertical mill. It is almost competent to grind ultra-fine materials with the vertical mill. For the embedded ore with fine particle size, it undoubtedly needs fine grinding or even ultra-fine grinding. With the excellent material performance of material science and technology, the vertical mill can meet these requirements. The application fields of vertical mill include metallurgy, mining, building materials, chemical industry, material industry, medicine, cosmetics, etc. (2) There
