Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying
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.
Ball mills can be lined with ceramics to reduce contamination from abrasive products but there is constant wear of the media, which may contaminate the product. Ball mills are often used in high volume, mine mouth operations where cost/ton has precedence over size distribution. What particle size range does a jet mill produce?

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

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.

A low-cost alternative for managing seasonal or peak capacity constraints; The service division processes a wide range of materials on a cost per ton basis
Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40 K√F

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Being a reputed ball mill manufacturer, we hold an extensive experience of manufacturing high-end ball mills for mineral plants, ball mills for paint industries and we even manufacture the best ball mills for mineral industries. There no better way to learn than by experience.

These costs represent 30% of costs for the 1 Mt/a plant and over 50% of costs for the 20 Mt/a plant. Thus, the "efficiency" of a modest plant is improved by simplifying the comminution circuit and reducing labour requirements. Improving the grinding efficiency of the comminution circuit by 10% will improve plant operating costs by less than 3%.
