Home / Applications Of Ball Mill On Large Scale
Ball mills scale up well and in fact improve in performed with increasing size. Ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5,000 gallon mills. Ball mills are available in various contact materials to accommodate contamination and wear requirements.Ball Mill Scale Up | Paul O. Abbe®,The rule of thumb for mill scale up is approximately 1-(√D/√d) where d is the diameter of the smaller mill and D the diameter of the larger mill. So going from a 12" lab scale mill to a 24" mill, 1-(√24/√12) = 0.4, so the larger mill may perform as much as 40% more efficiently.Ball mill - Wikipedia,A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the
May 01, 1984· Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges.
