The transformation of the development of mining machinery industry
At present, China’s policy adjustment in mineral mining and resource utilization has increased the cost of mineral development and utilization, which has brought great turbulence to the market of mineral grinding equipment. At the same time, it also puts forward new requirements for the performance and production cost of grinding equipment and other equipment. The […]
Global graphite consumption structure, trade pattern and application trend
The world is rich in natural graphite resources. According to the statistics of USGS (U.S. Geological Survey), in 2015, the global proven natural graphite reserves were about 230 million tons, of which 98% were concentrated in Turkey, Brazil, China and India, with reserves of 90 million tons, 72 million tons, 55 million tons and 8 […]
Purpose and method of pressing graphite material for graphite processing
At present, most carbon and graphite products are produced by extrusion. Molding method is often used to produce cold pressed graphite with small size or products with fine structure. Sometimes prebaked anode is also pressed by backlog method. Today, north electric carbon graphite processing introduces the purpose and method of graphite material pressing. The pressed […]
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 […]
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 […]
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 […]
On the unknown characteristics of talc powder
What is talc? Talc powder is called pulvistalci in English. It is a white or quasi white, fine and non sandy powder with greasy feel. Odorless and tasteless. This product is insoluble in water, dilute mineral acid or dilute hydroxide alkali solution. Main ingredients: calcite, a compound, is neutral, basically insoluble in water and soluble […]
Talc powder products for cosmetics can be safely used without unnecessary panic
Recently, the St. Louis District Court ruled on a lawsuit involving the use of Johnson & Johnson baby powder containing talc powder. Johnson & Johnson said it would appeal against this, which once again aroused the concern about the safety of talc powder. Johnson & Johnson stressed that it firmly believed that Johnson & Johnson […]

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 […]
A new measure to improve oil leakage of vertical grinding roller
1 existing problems Oil leakage of grinding roller often occurs in cement plants with vertical mill, which is a difficult problem that always puzzles vertical mill manufacturers. Oil leakage not only pollutes the environment, but also increases the production cost. There are many causes for oil leakage of vertical grinding roller, which can be summarized […]
