Design and Analysis of Impact Crushers

Patnaik, Sidhartha and Pattnaik, Biswajit (2007) Design and Analysis of Impact Crushers. BTech thesis.



Crushers are major size reduction equipment used in mechanical, metallurgical and allied industries. They are available in various sizes and capacities ranging from 0.2 ton/hr to 50 ton/hr. They are classified based on different factors like product size and mechanism used. Based on the mechanism used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. Our objective is to design various components of an Impact crusher like drive mechanism, shaft, rotor, hammers, casing, feed and discharge mechanism which will be useful in minimizing weight, cost and maximizing the capacity. Impact crushers: they involve the use of impact rather than pressure to crush materials. The material is contained within a cage, with openings on the bottom, end or side of the desired size to allow pulverized material to escape. This type of crusher is usually used with soft material such as coal, seeds or soft metallic ores. The mechanism applied here is of Impact loading which is applicable when the time of application of force is less than the natural frequency of vibration of the body. As because here the hammers are rotating at a very high speed, time for which the particles come in contact with the hammers is very small, so here impact loading is applied.
