Designing a Ball Mill

Posted in: , on 20. Dec. 2008 - 00:17

I'm currently working on a project that requires me to design a ball mill for crushing Sulphur powder.

The goal is to reduce 10kg of powder from 500 microns to 10 microns in around 5 hours.

The drum size is around 80L - does that sound right? And it sounds like balls will be used as the grinding media due to the initial size of the powder.

I was wondering if there are any equations I can use to determine the diameter/length ratio and the size of the balls in order to get a residence time of approximately 5 hours? Or is 5 hours not even feasible?

Any help would be appreciated

Salutation.

Here is my view on your take-on of your project. If you are getting it for any special pupose than it is ok. But objectively in this competitive and innovative technalized market people are going to have the VRM. Rather going for old tech you shud bit concern over to economical & ROI . Use of VRM is getting more response , not just it is power saving but having more technical advantage. This underlined message my exude is to go for VRM instead of ball mill that will get you to your scaled objective with more patternized manner

You should be talking to laboratory equipment suppliers. Ten kg throughput over 5 hours does not represent bulk material handling.
