#0183;#32;1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding ( its capacity to produce the desired final product).
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, etc.
Closed circuit ball mill: basics revisited Author: Jankovic, Alex Author: Valery, Walter Abstract. Since the early days, there has been a general consensus within the industry and amongst grinding professionals that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit ball mills.

Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG
Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns.; The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit open/closed
