Keywords: Ball mills, grinding circuit, process control I Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics Typical examples are the various ores, minerals, limestone, etc2017年6月2日· Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft in diameter to small mills used for sample preparation in laboratories Rod mills are similar to ball mills and use metal rods as the grinding media Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebblesHow it Works: Crushers, Grinding Mills and Pulverizers
Ball mill
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 pebbles2017年7月20日· Autogenous grinding is favored when the ore is quite competent and a fine grind is required Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency Figure 2 shows a typical conventional crushinggrinding circuit with three stages of crushing followed byAutogenous Grinding & Semi Autogenous Grinding Circuits
