10/03/20110183;32;Re How Can I calculate new ball size and weight desing for ball mill. Hi, We have a similar mill. Pregrinding with hammer crusher and mono chamber mill. Thisis what a proposed based on literture review i did and others agree its more and less correct. But remember it all depends on your mill feed size after pregrinding.
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.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It 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. A ball mill consists of a hollow cylindrical shell rotati
Enabling you to do all process calculations like; separator efficiency, fan efficiency, drying capacity of mill, power calculations, heat loss analysis, false air calculations, air consumption (kg air/kg clinker), coal consumption (kcal/kg clinker), power consumption (kWh/ton clinker), combustion calculations, volatile recirculation etc.
This relationship was successfully used for the scale up of a rocking ball mill, and the optimum design and operating conditions for the rocking ball mill could be estimated by the specific impact energy of the balls cal culated by a computer simulation.

Describe the components of ball mill. Explain their understanding of ball mill operation. Explain the role of critical speed and power draw in design and process control. Recognize important considerations in ball mill selection. Reading amp; Lecture. In ball mills, steel balls or hard pebbles to break particle based on impact and attrition.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 21 24 % of the empty mill. Now, in order to get an efficient milling action, 80 110 % of the pores in the ball bed must be filled with the actual particles to be ground. Then, by doing simple calculation, the particles occupy 11.2 17.6 of the mill volume.
Mill (grinding) , the free encyclopedia. A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting.
