Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially5–10 cm diameterbut gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

Scoop Feeders for Ball-Rod Mills are made in various radius sizes. Standard scoops are made of cast iron and for the 3′ size a13″or 19″ feeder is supplied, for the 4′ size a30″ or 36″, for the5′ a 36″ or 42″, and for the6′ a 42″or48″feeder. Welded steel scoop feeders can, however, be supplied in any radius.

Final fineness*: <1 µm. Product details. RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill Emax andMM 500were developed for grinding with the highest energy input.
First, a Jar Mill grindability test requires a5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.

The cost of aball millconversion from overflow to grate discharge is ‘fairly’ affordable at $65,000for a13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.
Ball mill classifier systems have been improved over time and are now capable of achieving much finer products. In the past, a particle size with aD97of10 micronswas only possible. Now particle sizes down to aD97of less than3.5microns can be achieved, with aD50in the range of1.5 microns.
The balls which could be of different diameter occupy 30 – 50 % of themillvolume and itssizedepends on the feed andmill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fineproductby reducing void spaces between the balls.Ball millsgrind material by impact and attrition.

Also, the uprising velocity in themillcan be controlled by a recycle pump to affect theproduct sizedistribution, prevent over grinding, and reduce the circulating load from the cyclone.Final product sizeis a factor of applied grinding power, flow rate, and slurry density.
Smaller the required particlesizeof thefinal productis, the longer time it will take aball millto grind the material, which will decrease the ore grinding effect and the output. 3. Working Condition According to aball mill’s working principle, materials are mainly ground by its grinding media.
