Computation of charging media for a double compartment …

Axial rotation of ball mill provides cascading action of steel balls which crush the raw material due to attrition between steel balls which is known as grinding media. Grinding media is mostly prepared from high chrome steel. Ball mills are efficiently utilized for final grinding of clinker. It grounds the raw mix (clinker) into fine powder.

Grinding Mill Power

If now ξ is the ratio of the power to drive the mill charged with balls and powder to the power to drive the same mill with a ball charge only, then: ξ = Wt. of ball charge x Wt. of powder charge/Wt of ball charge. If also it is assumed that the porosity of the ball charge and of the powder is 0.4 in each case, then:

PVC as a ball mill tumbler

Sorry for the delay in responding; have had a very bad cold. So, I ball mill the oxidizers in one container and then ball mill the BP mix in another. The components are inexpensive so making separate containers is cheap. I have a third for ball milling charcoal. I have every thing set up for a comparison test and will hopefully get a video tonight.
