"DESIGN AND DEVELOPMENT OF A ALTERNATE MECHANISM FOR

In this paper alternate mechanism for design and analysis of small size stone crusher mechanism is proposed. The basic idea is to optimize the design of the crusher which would be best suited for stone which need crushing force of 3 Tons. Presently for reducing sizes of stones from 10cm x 10cm to 2.5cm x 2.5cm in quarries is laborious job and is done manually our approach is to design a best
