First, the product uses: mainly used in cement mill grinding cement raw materials and finished products, also used in metallurgy, chemical, electric power and other industrial and mining enterprises grinding various ores and other materials may be grinding. It can be used to open circuit grinding, also suitable for cycling circuit grinding and separator composed. Second, the principle of ball mill: This machine is a cylindrical rotating device, outer gear, the two positions, lattice-type ball mill. Material from the feed device evenly into the mill first warehouse into the compound by the air shaft spiral, the warehouse has ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive. The material in the first position coarse grinding, the single-compartment plate into the second warehouse, the warehouse lined with flat lining, the steel ball, the material to further grinding. Powder is discharged through the discharge grate plate to complete the grinding operation. Third, the mill components: the cylinder, linings, diaphragm plate, main bearings, feed and discharge means gearing four cement mill features: Cement mill having materials adaptable, capable of continuous production, broken than large, easy-to-governor grinding fineness of the product features. Production of cement mill capable both wet production can also be grinding and drying operations simultaneously. Fifth, to provide quality services: Before the purchase by the engineering and technical personnel to conduct site planning, design and installation of flow programs; after the purchase send technical personnel to the scene to guide the foundations, installation and commissioning. Sixth, quality assurance: three bags of products one year.
