Below you can find 3 different sizes of quality ball mills to meet your needs. We have 3 Lb, 6 Lb double barrel for mixing two different comps at once without having to clean your barrel and a large heavy duty 15 Lb mill for the larger jobs. All are priced to sell and of high quality to be around for years with continuous-duty electric 110V motors NOT 220V. If you plan on using these mills on 220V which many do, you can buy a good 100 watt power convertor for your mill to convert to 110V. We sell alot of mills to folks who have 220V. You can buy these convertors many places but here http://www.netzgeraet.de/index1.html?spannungswandler_wandler_230vac_auf_110vac.htm is a good place to purchase what you need to make these mills work efficently. Also we offer extra lead-antimony media so you may add extra to decrease your grinding time or have some for each comp so you don't have to clean media between grindings. These units are not only used in pyrotechnics but in Labs, schools and any other application that requires grinding to a fine powder with or without water.
