HD Technologies Case Study: Ball Mill Bearing Damage

This case study describes bearing damage detected through online measurements taken from a ball mill at the flotation plant of Asarel Medet AD in Bulgaria. Asarel Medet AD is among the largest Bulgarian mining companies for the extraction and enrichment of copper ores, located in the territory of Panagyurishte in the Pazardzhik district.

DEFINITON: • A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering etc. 6. PRINCIPLE: A ball mill works on the principle of impact and attrition. size reduction is done by impact as the balls drop from near the top of the shell.

This study used the discrete element method (DEM), which is effective and popular for solving the problem of granular systems simulating the motion of particles in a ball mill in different structural forms and at different rotational speeds. Firstly, simulations of five

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different

Using a 5 litre batch mill, an experimental programme was designed to study the comminution characteristics of the stirred mill. A factorial design was prepared with the following parameters, which influence grinding in the stirred ball mill: pulp density, pin tip velocity and ball density and size.

A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the balls, which may be made of steel (chrome steel), stainless steel, ceramic, or rubber.

Introduction: ball mill is a key equipment for grinding materials after the crushing process, which is widely used in the manufacturing industries such as cement, silicate sand, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Ball mill can grind various ores and materials with dry type or wet type.

Ball-mill noise became a matter of general concern with passage of the Walsh-Healy Act in 1969. This act is now a part of the broader safety act known as the Occupational Safety and Health Administration. Noise is one of the ``newest pollutants'' in terms of the definition set forth in the Walsh-Healy Act. Studies are currently underway to establish standards by which to determine conformity

The idea of using a mixture of balls and pebbles, at a mill speed suitable for ball-milling, was revisited in this investigation, using a normal spectrum of pebble sizes (19-75 m). Batch tests in a pilot-scale mill (0.57 m diameter) were used to compare ball-milling to various ball/pebble mixtures.
