Abstract
The impact crusher is widely used in special hard, hard and abrasive materials, rough broken and mechanical crushing operations efficiency impact crusher. Through this graduation project, to study on the consolidation of book knowledge. Early in the design, to inspect the information about the impact crusher at home and abroad. Then follow the impact crusher of the general design steps of the following design: the overall plan of impact crusher and calculation and choice of the main shaft and the other major parts to determine structural parameters; the calculation of impact crusher working parameters; impact crusher structural design; check of the stress analysis and strength of major components. Finally complete a assembly drawings of impact crusher, parts diagram , the design of a paper.
Key words: impact crusher; conveyor belt; impeller; shaft
