Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).
WhatsApp: +86 18203695377The ball size in a mill has a significant influence on the mill throughput, power consumption and ground material size (Austin et al., 1976; Fuerstenau et al., 1999; Kotake et. al., 2004). The basic condition, which must be met while grinding the material in a mill is that
WhatsApp: +86 18203695377ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.
