Ball Mill Design/Power Calculation

A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as …

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

grind size. For any process, including ball mill circuits, we can say that output equals input multiplied by efficiency*. Output = Input x Efficiency In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies.

Optimum choice of the make-up ball sizes for …

01.09.2013 · Fig. 5 shows the equilibrium ball size distribution from various portions of three make-up ball size classes: 50.8 mm, 35.9 mm and 25.4 mm. The minimum ball size in the charge was taken as 12.7 mm in this example. For a single size of make-up balls, the ball size distributions exhibit a mono-modal size distribution with a mode close to the original make-up ball sizes. A 1:1 mixture of two make-up …

How Ball Mill Ore Feed Size Affects Tonnage & …

For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day. The gain in production compared to the 13,000 micrometer feed will be:

Ball Mills - an overview | ScienceDirect Topics

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long …

Ball mill - Wikipedia

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

Relationship Of Ball Mill Output With Input In …

Relationship Of Ball Mill Output With Input In Excel; Relationship Of Ball Mill Output With Input In Excel . so I made a test world and did a 64x64 run with 3 mills 1 with nothing one with flint and one with a dark ball The dark ball mill finished long before the others did the flint finished 6 stacks quicker than none did And the resulting output for each Input for each64x64 4096 None32x6411 ...

How to decrease particle size of alumina powder …

I have 63 micron alumina(Al2O3) powder and I want to decrease its particle size down to 15-20 micron with ball milling. I have a few questions:
