The Rotor consists of circular supporting plates known as Discs, Hammers, Bearing blocks, Flywheels, Belt Pulley and the Main Driving Shaft. The main driving shaft is forged from thick alloy steel round duly tested on which the discs are mounted. These discs are placed on hardened bushes and are attached by tie-rods. Every part is duly machined and weight balanced with double roller taper bearings provided as per the requirement for smooth operation of the machine. The hammers are manufactured out of costly, special alloy steel cold rolled castings containing 11-14% Mn, 1.0-1.3% C, Si, P & S in the required proportions as these are very essential part

of the machine. The Hammers are connected to the rotor through axles called hammer pins. The hammers are placed around the rotor in balanced positions. The discs do not take any direct blows which instead were taken by the hammers as they do their work on the anvil, thus reducing the wear and cost of maintenance. The disc design also is convenient for automatic welding for hard surfacing during maintenance periods. As the discs rotate, the hammers extend from the rotor due to inertia. When they hit a piece of scrap, the energy is transferred from the hammer to the scrap. If the scrap piece is not immediately fragmented, then the hammer is deflected backwards. It might even bounce all the way around 360 degrees but will always return to the initial position. The shredder housing contains the flying pieces of scrap and efficiently directs these pieces to the grate areas. The rate at which the scrap is fed inside the machine is in proportion with the load on the main driving motor. This leads to the controlled amount of scrap in the shredding chamber and the stress on the hammermill.

Since, lot of rust, dust & colour contents blow up at the time of shredding, a suitable outlet is required. Therefore we have provided one big outlet at the top of shredder and another on the opposite side of the feeding hopper for their easy outflow. Further, a taper mesh on which the material shall pass is provided outside the machine so that the dust is re-collected under it.

Dust Collector Cyclone
The Jain Hydraulics dust collector consist of a special material handling blower, motor, bag tree with collection bag and filter. The material handling blower uses a material handling impeller. It is made fairly self cleaning, letting chips and strings slide off instead of getting trapped. The impeller turns in a spiral shaped blower housing that needs to be very smooth to minimize the disruption of airflow. The blower housing outlet then directs the collected air and chips into a bag tree where it spins in a centre separation ring. Thus, all the small & large dust particles coming out of the shredder machine enter the cyclone thereby leaving the environment clean.
Other than the main machine, the Jain Hydraulics shredder plants also consist of the following as its integral part:
