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 government also pays more attention to the development and utilization of metal and non-metallic resources, Such a market prospect is a good trend for the development of milling equipment and mining industry.

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 million tons respectively. China is a large country of graphite resources. In addition to meeting the huge domestic demand for graphite, graphite production is also exported to Japan and European countries. For

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 paste is just pressed into the required shape and size by the pressure equipment and the semi-finished product (green blank) with high density. Extrusion method and molding method are commonly used in

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

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

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

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 in hydrochloric acid. Among many types of inorganic powders, talc powder is a special one, which is especially reflected in its diversity and complexity. Talc powder has the characteristics of stability, low

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 baby powder was safe. In addition, Many organizations and experts also said that cosmetic grade talc powder is safe. The latest statement issued by Johnson & Johnson in May stressed that in

Ultra precision grinding with diamond micro powder grinding wheel, existing technical problems and development prospect. The ultra precision grinding mechanism of diamond micro powder grinding wheel is discussed. It is considered that it is the fusion of multiple functions dominated by micro cutting; The dressing mechanism of diamond micro powder grinding wheel and its common effective dressing methods are studied; The conception of resin metal composite bonded diamond micro powder grinding wheel is put forward, and its structure formation, manufacturing process and actual grinding effect are discussed.
