New Design Idea of Crushers Used in Cement Factories

ABSTRACT The present work a new design idea of a crusher to be used in the cement factory in consistence with the existed working conditions; the new design is named a hybrid crusher. This crusher consists of the three cylindrical rollers; they are used for reducing stone to small size by three stages, working as a primary, secondary and fine crusher. This is beneficial due to the reduced primary cost, lower power consumption, reduced working time, decrease of maintenance and avoiding transportation of material from primary crusher to secondary crusher machine. Using this hybrid crusher leads to increase the production per hour and high reduction ratio more than all types of crusher, and it is a highly simple machine and easy to change all its parts. For this design, the calculations were conducted for all items used in this machine, and detailed drawings for all items were prepared in addition to 3D modeling picture and 3D animation for presentation
