Capacities and performance characteristics of jaw crushers

By using the data of E.A. Hersam and F.C. Bond's equation for energy consumption in comminution, a method was developed to analyze the performance of industrial jaw crushers. The study showed that industrial jaw crushers are generally operated below capacity. The study also showed that industrial jaw crushers generally have sufficient …

How to Prevent Crusher Choking

If a condition of near-choke should exist just above the discharge level, a large movement of the head may be sufficient to complete the choke; whereas a smaller throw would not be so likely to "follow through" to that extent. It is apparent that the choke-point in the crushing chamber we have been discussing is at the discharge level, or ...
