Apr 01, 1988· The effect of ball size is significant and must be taken into account in the scale-up. A method has been developed for specific selection function conversion from one ball size to another. A preliminary RTD correlation between transport characteristics andmill design and operating variableshas been developed for the scale-up design of large mills.Get Price
Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, thelargest ball mill in operationis8.53 m diameter and 13.41 m longwith acorresponding motor power of 22 MW (Toromocho,private communications).Get Price
Grinding (Rod) or (Ball) Mill TYPED Has single weld, triple flanged, construction which means the shell is furnished in two sections, flanged and bolted in the center. All flanges are double welded as well as steel head to shell, note design. Tumbling Mill (Rod or Ball) Mill TYPE E Has quadruple flanged construction.Get Price

The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
