TECHNICAL NOTES 5 CRUSHERS Mineral Tech

2009-7-30  Breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory. High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers.

DESIGN AND ANALYSIS OF IMPACT CRUSHERS nitrkl.ac.in

2012-7-4  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
