The surface of the cast grinding steel ball is not allowed to have the casting defects such as the crack, and the obvious gas porosity, inclusion, shrinking cavity, cold shut, elephant skin, etc.. It is not allowed to have the shrinkage cavity, shrinking porosity, gas porosity, inclusion, and other cavity defects on the section including plane pasting through the pouring gate and the ball centre.
A ball mill, a type of grinder, is a cylindrical device used in grinding 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.
Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types rod, ball, pebble autogenous and semi autogenous. The grinding action is induced by relative motion between the

5 Ball mills are used for wet grinding iron ore, gold/copper ore, nickel ore and other ores, as well as lime/limestone for flue gas desulphurisation systems, coal and other raw materials.
The ball mill is a key equipment for regrinding. It is widely used for the cement, iron ore beneficiation, gold ore beneficition, new type building material, fire proof material, chemical fertilizer, black and non ferrous metal, glass, ceramics and etc.. Our ball mill can grind ore or other materials that can be grinded either by wet process or by dry process.
Ball mills are short cylindrical vessels with a shell to diameter ratio of 1.5 to 1 and less. When the length to diameter ratio varies between 3 and 5 it is called tube mill. The grinding medium is high carbon or cast alloy steel balls. The particle size of the feed usually does not exceed 20 25 mm.
