Abstract. A specific energy-based size reduction model for batch grinding ball mills was reported in a previous paper (Shi and Xie, 2015). A discharge function modified from the Whiten classification efficiency equation has been incorporated in the size reduction model to extend its applications from batch grinding to continuous operation.
Ball size is one of the key factors of ball-mill efficiency [11,12], and may have a significant financial impact . The population balance model (PBM) has been widely used in ball mills [ 14 ]. This model is a simple mass balance to reduce size being used in fragmentation models [ 15 ].

During the last decade, semi-finish-grinding plants have been used more and more for the energy efficient grinding of high-quality cement. In 1999, it was found that by decreasing the ball charge filling ratio it was possible to lower the specific energy demand for grinding significantly.. It was obvious, too, that the L/D ratio influences the …
Ball mill is a type of grinding equipment that uses the rotary cylinder to bring the grinding medium and materials to a certain height and make them squeeze, impact, and grind and peel each other to grind materials. Ball mill is the key equipment for crushing materials after they are crushed. It is widely used in cement, silicate products, new ...

Type "D" Ball and Pebble Mills. One of the most popular designs, the Type D mill is available as a steel ball mill with or without steel plate wear-liners, or as a lined ball or pebble mill utilizing Alumina, Buhrstone or rubber linings. Type D ball and pebble mills are available in a variety of standard sizes from 15 inch to 8 foot diameters.
First, the slurry begins to fill up to the lip of the overflow opening before it starts to discharge through the mill trunnion. When the solid is fed at a constant rate of 109 kg/h to the empty mill filled only with the ball media, it takes some time to fill up the mill as seen in Fig. 2.For some time, the slurry accumulates in the mill while it fills the voidage …
