BOND BICO BALL MILL

BOND BICO BALL MILL The Bond Ball Mill is a small universal laboratory mill used in calculating the grindability of all ores. GRINDABILITY IS THE NUMBER OF NET GRAMS OF SCREEN UNDERSIZE PRODUCED PER REVOLUTION. This Ball Mill can be used continuously or it can be used for any number of revolutions, according to the type of grind desired.
