Ball bearings are very common part of most of the machines that we use for domestic as well as industrial purposes. Ball bearings are used in automobiles, fans, motors, pumps, elevators, pulleys, grinders, turbines, lathe machines, drilling machines, milling machines, cutting machines, heavy trucks, etc., everyday millions of ball bearings fail across the globe and gets replaced by a new ball bearing. 90% of the bearing failures are due to seal failure and entering of water in to the bearing. Water causes rusting of balls, increases in friction between inner & outer race and finally results in bearing failure. Only in rear cases few balls get failed due to heavy or shock loads, that means most of the balls of the bearings don't crack even after bearing failure. Recycling of these balls will help reduction in waste generation as well as save money. But there is no machine available in market for de-rusting of balls of ball bearings. As a part of our project dissertation, we are performing design and fabrication of roller based centrifugal balls de-dusting machine that helps in ball bearing recycling. The machine mainly consists of a collar shell, rollers, drive motor and support structure.
