What grinding equipment is used for construction waste treatment

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 and carry out resource treatment of construction waste. In fact, after professional treatment,

Raymond mill is a sharp sword for silicon carbide powder processing

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 and an appropriate amount of salt when preparing green silicon carbide) it is

Latest market of graphite

The graphite market soared all the way, and the price finally stabilized at the end of August. At present, the 19th national congress is about to be held. The mine explosives in Jixi and Luobei, Heilongjiang Province are stopped, resulting in a slight rise in graphite in Northeast China. The shutdown of flake graphite and expandable graphite enterprises in Shandong is very serious. In the later stage of inventory sales, the price of graphite products is comparable to real gold, and the production in Inner Mongolia is

The production process of heavy calcium carbonate is mainly divided into dry process and wet process

Calcium carbonate, also known as grinding calcium, is a powder product with natural calcite, heavy calcium carbonate, limestone and chalk as raw materials and reaching a certain fineness through mechanical crushing and grinding. It is generally called fine grinding calcium carbonate (FGCC) in the world. Heavy calcium carbonate is divided into coarse ground calcium carbonate (> 3) according to its original average particle size (d) μ m) . finely ground calcium carbonate (1 ~ 3) μ m) . ultrafine calcium carbonate (0.5 ~ 1) μ m)。 The

Role of heavy calcium powder in various industries

In recent years, due to the improvement of environmental protection awareness, the state has vigorously advocated environmental protection, and its ore processing has reached an economic climax. As we all know, heavy calcium carbonate is referred to as heavy calcium for short. It is a white powder processed with high-quality calcite as raw material. Its main component is CaCO3. It has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Therefore, heavy calcium is a good filler commonly used in industry. Heavy calcium

Do you know the correct opening method of the sealing knowledge of the roller bearing of the vertical mill

Sealing plays an important role in preventing “three leaks” of mechanical products and ensuring the normal lubrication action and safe operation of equipment. The vertical mill has high requirements for sealing, especially for the grinding roller bearing. The oil seal is set between stationary and rotating parts to prevent lubricating oil leakage and prevent impurities such as external dust and materials from entering the inner cavity of the bearing chamber. It has the characteristics of simple structure, good sealing performance, shaft swing and eccentric follow-up performance. Therefore,
