Pulverizers are machines that pulverize large solid materials to the required size. Pulverizer Machine,Crushing Machine,Milling Machine,Grinding Mill, Grinding Machine JIANGYIN CITY XUAN TENG MACHINERY EQUIPMENT CO.,LTD , https://www.xuantengmachine.com
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
Kumi FRP's independent research and development fills the domestic gap
A section of glass steel pipe (purchased by the product warehouse) actually has 13 utility model patents. Suzhou Jiumei FRP Co., Ltd. independently developed the ship and marine engineering FRP pipeline, not only took the lead through the China Classification Society (location contact) Far East Fire Test Center three-level fire test, filling the domestic gap, but also passed the US Southwest Research Institute's spray resistance The fire test received a type certificate from nine classification societies. Recently, Kumi FRP and a US company won the competition and won the bid for the ballast and sweeping system project of the world's largest 400,000-ton bulk carrier (ship-type shipyard).
     Suzhou Jiumei Company is a “new three board†listed company in Panyang Industrial Park of Xiangcheng High-tech Industrial Development Zone. In 2006, Chen Helong, born in Nanjing Gaochun, the hometown of shipbuilding, came to Huangqi Town, Xiangcheng District to invest in Suzhou Jiumei FRP Co., Ltd.
     Ship and marine engineering FRP pipes are mainly used in marine and offshore platforms (ship type shipyards) marine water systems, ballast, fire protection (product library supply and supply) systems. At the time, due to limitations in domestic technology, this material relied on imports. At the beginning of the company's founding, Chen Helong established a research and development team, and worked with R&D personnel to drill into the laboratory, sometimes working for more than ten hours a day.
     For shipbuilding and marine engineering FRP pipe products to be used for shipbuilding, it must be certified by the classification society. In the certification process, the degree of fire resistance of the product is a very important indicator. At the same time, in addition to fire prevention, it is necessary to ensure that the product is smoke-free and non-toxic after being burnt. Chen Helong said: "The classification society has three fire protection grades, and the minimum standard must also reach the third-grade fire resistance."
     After several years of research and development improvement, Chen Helong took the self-developed products to participate in the third-level fire-resistance certification test with enthusiasm, but the result ended in failure. Although no company in China was able to pass the three-level fire test at the time, Chen Helong was not discouraged. While encouraging the R&D team to cheer up, he went to the Institute of Nanomaterials of the Chinese Academy of Sciences to seek cooperation and technical support.
     How can the FRP pipe be smoke-free and non-toxic in the environment of 700 ° C to 1000 ° C, while ensuring that its internal structural properties do not change? Chen Helong and the R&D team repeatedly watched the video footage of the test failure and continuously improved the materials. After hundreds of experiments, the formula of flame retardant dosage was finally studied. In 2012, the glass fiber reinforced plastic pipe independently researched and developed by Jiumei Company finally passed the three-level fire test of the China Classification Society Far East Fire Test Center, becoming the first product in China to pass the test. In 2015, the shipbuilding and offshore engineering FRP pipes produced by Kumi FRP increased the fire resistance to 1200 °C, passed the anti-spitfire test of the Southwest Research Institute of the United States, and also marked the “International Pass†for Suzhou Jiumei FRP.
     Today, Kumi FRP has obtained type approval certificates from nine classification societies such as American Bureau of Shipping (ABS) and French Bureau of Shipping (BV), with an annual output of 8,000 tons of FRP products, not only The main manufacturers of Chinese ship (stock) and offshore engineering FRP pipes have also entered France, Singapore, Germany and other places. In May 2015, Kumi FRP was listed on the “New Third Board†in Beijing and became the first listed company among domestic FRP companies.
