Ball Mills

The ball mill method was first invented by Shimadzu in Japan in 1924 Nowadays, a great variety of mill designs are in use, but the basic principles applied by Shimadzu remains the same The ball mill process is based on solid-phase reactions and operates within the temperature range between 70 and 180°C...

Bond Work Index

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 310), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ....
