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 installed power to operate at full capacity. The method presented

Capacities and performance characteristics of jaw crushers

Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher. The equation proposed by Hersam includes a

Crusher - Wikipedia

A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber. The movement of the swing jaw can be quite small, since complete

Jaw Crushers - Binharkil

24/07/2016  Jaw Crusher . Jaw crusher consists of a set of vertical jaws, one being fixed or stationary and the other moving or mobile. The back and forth motion of the moving jaw, relative to its mechanism, causes the crushing motion for this machine. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it ...
