Perhaps consider taking your savings in materials for a jar, motor, and wood/hardware, and spending a little on media. You never stated how large of a mill you're intending to make, but you can supply a mill capable of making about 200g of BP per batch with media for about $20-25 in lead.
• The normalized output tracer concentrations in ball mills were reconstructed, using the model of N perfectly mixed tanks in series. The N parameter ranged from 2.1 to 3.9, in which more than the 80%of the experiments reported N = 2.0 - 3.0. • The mean residence times in ball mills were found around 2.5 - 4.0
Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ...

Motor power and media addition. The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.
