DESIGN OF MECHANICAL CRUSHING MACHINE

This crusher works on the simple mechanism called crank and slotted lever mechanism. When the motor is excited using a power source (i.e.3-phase power supply in this case) the shaft starts to rotate which in turn rotates the pulley which is connected to the motor by means of a belt drive. This pulley gives rotary motion to the transmission
