#0183;#32;Schellinger''s calculated ball mill efficiency, in dry or wet ball mill grinding, ranges between 10% and 19%, with the higher figure occurring at the optimal mill loading. In terms of the Brace and Walsh surface free energy of quartz, his results give a ball mill efficiency that is less than %.

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.
#0183;#32; Grinding. Dry grinding tests on high purity hematite were carried out in a planetary ball mill (Pulverisette6, Fritsch) with one steel pot of 50 cm 3 inner volume, under atmospheric conditions (Sanshez et al., 2007, Pourghramani and Forssberg, 2007a, Pourghramani and Forssberg, 2007b).Steel grinding media ( = g/cm 3) with ball to powder ratio of 3:1 was used in this milling

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and 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.

Sulphide coppergold ores are usually sorted by flotation. The standard comminution process to grind the ore to flotation fineness, mostly consists of coarse crushing followed by SAG milling or wet ball mill circuits, or alternatively multiple stage crushing followed by rod and ball milling.
Typical in the ores, minerals, paints and general chemicals industries, ball mills can be designed to operate continuously (fed at one end and discharged at the other), or on a batch basis. Each of these mill types can then be combined with external classifier stages, with or without feedback, to create an overall process that is as efficient and costeffective as possible.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material.
#0183;#32;Practical 1: Title: Ball Milling Objective: To grind the coarse salt to a smaller size by using a ball mill and to obtain the particle size distribution of the initial and the sieved final mixture. Introduction: ''Ball milling is a method used to break down the solids to smaller sizes or into a powder. A
