how ball mill ore feed size affects tonnage & capacity the important of crushing your ore and rock fine and properly is often forgotten. the finer you crush, the higher your ball mill tonnage and capacity will be. the effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of crushing.

calculate and select ball mill ball size for optimum grinding in grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a mineral processing engineer aka metallurgist to do. often, the ball used in ball mills is oversize “just in case”. well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

how coarse can ball mill feed be grinding feeding >15mm to a ball mill this size is not typical much larger ball mills (>21' or 7.0m diameter) typically get 12-16mm feed (from what i have seen in my experience) with regards to 3.5"- 4" media, typically for ball mills of this size (16'), max size of ball used should be around the 50-60mm.

feed size vs ball size grinding & classification for ball mill, bond (1958) was proposing an empirical formula giving the top size of balls (make-up balls) dm function of the feed size xg (80% passing size µm), the ore true specific gravity sg, the ore bond work index wi (kwh/st), the fraction of critical speed fc and the inside mill diameter d (m):

tailoring ball mill feed size distribution for the evidence that particle breakage during milling varies with material size is commonly cited in literature. this makes feed tailoring in ball milling an interesting parameter to investigate with the aim of maximising the desired mill product.

ball mill wikipedia the ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. the ball mill can grind various ores and other materials either wet or dry.

how to size a ball mill -design calculator & formula  a) total apparent volumetric charge filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners). b) overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge; causing, the total charge filling level to

ball mill: operating principles, components, uses 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 large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. ball mills grind material by impact and attrition.

ball mill an overview sciencedirect topics the ball mill accepts the sag or ag mill product. 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 initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills (dry basis) is typically 75 vol

ball size distribution for the maximum production of a the simulated product size distributions were found to display a close match with the measured product from an operational mill. based on the maximum production of floatable particles, the best combination of make-up ball size was determined in relation to feed flow rate, feed size distribution and ball filling.

optimum choice of the make-up ball sizes for maximum however, as a group, they are not entirely satisfactory because the optimum mixture of balls depends on the feed size as well as the product size. further, the ball size distribution in the mill is not a simple parameter that can be controlled directly, as it depends on the make-up ball charge and wear rate. therefore, the industrial practice
