Ball Mill Design/Power Calculation 911 Metallurgist
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum Ball Mill Capacity VS Rod Mill Capacity. In this equation, E is the specific energy required for the grind, and F80 and P80 are the sizes in micrometers that 80% of the weight passes of the mill feed and product respectively. The parameter Wi, known as the work index of the ore, is obtained from batch bench tests first devised by Bond (1961Ball Mills 911 Metallurgist

Charge behaviour and power consumption in ball mills:
Fig. 2 shows the variation of the average torque and power with mill speed for the ball mill described above with a fill level of 50%. The torque increases slowly until the peak is attained around N=80%.As the amount of cataracting increases, the balance of the charge improves and the torque required to maintain the asymmetric charge position The capacity of a ball mill depends on several factors including the size of the ball mill, the type of material being ground, and the operational parameters of the ball mill.

Ball Mill Principle, Construction, Working, and More Soln
A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for single-stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits.High mill filling levels were always used to put maximum energy between the trunnion bearings until the use of low filling levels initially was encouraged to prevent a failure on a dual drive ballBall charge loading Impact of specific power consumption and capacity

The energy efficiency of ball milling in comminution
A ball mill employs steel balls to generate a grinding action, i.e. ore particle comminution via impact and abrasion with steel balls, and is a key component of beneficiation plant productionAbstract. The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.An overfilling indicator for wet overflow ball mills

Ball Mill an overview ScienceDirect Topics
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
