A ball and tube mill is a low speed machine that uses steel balls in a rotating horizontal cylinder to grind coal. It is called a tube mill because of its shape, and a ball mill because it uses grinding balls for grinding, or a balltube mill in both terms. These mills are also designated as sample size BBD4772. B Broyer (inventor's name).
