In ball millingthe desired particle size is achieved by controlling the timeapplied energyand the size and density of the grinding media What size and how many balls would you recommend for the ND4L? Also what is the smallest particle size the ND4L can mill down to? Our ball mills always come with a free standard set of ballsincluding 1000 6mm balls200 10mm ballsand 3 20mm balls for EACH 1000ml jar They do the basic job of filling each jar to about 12 of its volume
The design of a ball mill can vary significantly depending on the sizethe equipment used to load the starting material (feeders)and the system for discharging the output product Yet few potters even have a ball mill or know what one is Article A true ball mill is a porcelain jar partly filled with spherical or rounded cylindrical porcelain balls Industrial versions are made of metal and have porcelain linings
rate at each screen size is calculated from a torque-mill test as in the example that follows You can find from instructional manual of the mill Howeverthis can change according to the material you are grinding For examplefor a cement mill with two chambersin the first chamber you have to have an average ball size of 75-80 mm
For example grinding with planetary ball mill makes a wide PSD which is not desired01-mm diameter The Micro Ball seriesNSMB100offers sizes from 0 01-mm to 0 1-mm diameter NS Tools other series feature size ranges of 0 1-mm to 12-mm diameterensuring tools are available for every application
