Ball mill is crucial equipment for grinding after materials are crushed. It is an efficient tool for grinding various materials into powder.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. Ball mills are used extensively in the Mechanical alloying process in which they are not only used for grinding but for cold welding as well, with the purpose of producing alloys from powders.
Ball Mill Application
Ball mill can grind quartz, feldspar, barite, fluoride, cinder, cement clinker, dolomite, limestone, gypsum, talcum, calcite, bauxite, granite, slag, gold ore, clay, kaolin, graphite, basalt and so on. Ball mill grinding material requirements are non-flammable, non-explosive minerals with Moh’s hardness<9.3, humidity<6%.
Ball Mill Working Principle
Ball mill is horizontal type and tubular running device, has two warehouses. This machine is grid type and its outside runs along gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device.
In this warehouse, there is a ladder scale board or ripple scale board, and different specification steel balls are installed on the scale board, when the barrel body rotates and then produces centrifugal force, at this time , the steel ball is carried to some height and falls to make the material grinding and striking. After grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scale board. In the end, the powder is discharged by output material board and the end products are completed.
Ball Mill Features
1. The hollow axis adopts the cast steel and the lining can replace, the rotating big gear processes in the way of casting rolling gear.
2. The barrel body is wearable well and bears wearable scale-board.
3. This machine run steadily and works reliably.
