Best way to determine the ball-to-powder ratio in ball-milling?

Then, the optimal mass ratio of ball to powder in ball mill is 7.5*24/(2.5*17.6)= 4.09 to 7.5*21/(2.5*11.2) = 5.63.

Ball mill know more a typical ball mill will have a drum length that is or times the drum diameter ball mills with a drum length to diameter ratio greater than are referred to as Grinding in Ball Mills Modeling and Process Control The design of a ball mill can vary ...

Ball Mills - an overview | ScienceDirect Topics

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.

Ball mill - Wikipedia

A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:−2 or 1:−1). The grinding balls in the grinding jars are

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 ...

How can one select ball size in ball milling and how much material …

More balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling ...
