Cone Crusher

The power drawn by a crusher can be changed by varying the feed rate and/or the setting, as shown in Figs. (11) and (12). A small change in setting can bring about a large change in power rate, Fig. (13). Changing feed rate near optimum power draw gives small change to crusher power rate and the reduction ratio remains approximately the same.
