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.machineryxuanteng.com
When domestic enterprises introduce equipment, foreign suppliers only provide hardware. After there are problems in production, there are no reasonable parameters, which often lead to quality problems, which makes the smooth operation of equipment face a lot of tests. To this end, Baosteel Branch Steel Pipe Plant and related research institutes set up an inter-departmental joint group to carry out research. After trial and error and continuous exploration, find reasonable process parameters. At present, the butt welding process of four specifications has been formed and determined, and the smooth production of large wall thickness and extreme specification products has been realized, and it has become a unique standardized production mode of Baosteel.
It is reported that at present, the research team is actively exploring the butt welding process of various specifications of products around the outline of steel pipe products, with a view to achieving a comprehensive breakthrough.

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.
Baosteel developed a medium-diameter straight seam welded pipe butt welding process
Recently, the butt welding production process of the four products of the medium-caliber straight seam welded pipe independently developed by Baosteel Co., Ltd. has become increasingly mature, and there is no broken band phenomenon after the use, which ensures the continuous production of the unit. This is the first mature process in China for high-speed double-wire gas shielded welding.
