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 (i.e. its capacity to produce the desired final product).

Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.

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 pebbles ...

cyclone is returned to the ball mill. Balls are added periodically to the mill on a per shift basis or when the power draw drops below a preset value at nominal operating conditions. SmartGrind was installed on Mill No.5 and its performance was compared to the neighboring Mills 3 and 4.

Outotec has designed, manufactured and installed over 8,000 ball and pebble mills all over the world for a wide range of applications. Some of those applications are grate discharge, peripheral discharge, dry grinding, special length to diameter ratio, high temperature milling oprations and more.

Mill circuit cyclones from Multotec maximise mill efficiency and reduce the energy per ton required.This is achieved via their unique inlet design and, additionally, the cyclone configuration can be altered to accommodate changing operational conditions.. Improved mill capacity by this cyclone, part of Multotec's range of classification cyclones, facilitates increased throughput.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

The scope was the complete upgrade of the Concentrate Mill which included the Feed Conveyor system to the four SAG Mills, the eight Ball Mills with all their conveyors and lubrication systems, the Cyclone Feed Pump systems, the Cooling Towers, the Air Compressor Plant, the Gland Seal Water system, Lime Plant as well as the remote-controlled ...

2. Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding.

the ball mill indicated by an above target power draw. Once the feed density was reduced to increase the recirculating load, both ball mill power and cyclone overflow particle size fell. Figure 4 Reduction of grind size with constant TPH and target ball mill power – 6 – In order to maintain target particle size and power draw, the cyclone ...

The 28 MW mill will be 12.2 m in diameter with an effective grinding length (EGL) of 8.2 m. Ball milling will be accomplished in a single 22 MW, 8.5 m diameter, 13.3 m EGL (effective grinding length) ball mill. It will be fed by a combination of SAG mill cyclone underflow and recirculated ball mill cyclone underflow.

The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.

A $15 million capital cost would also be incurred in any ball milling circuit targeting a 34 µm product for finishing screens which are needed to minimise silica and to protect the concentrate pipeline. The ball mill cyclone combination cannot guarantee elimination of +100 µm particles from the pipeline feed.
