Lamp processing machine

A method for separating glass, powder and metal lamp components, comprising the steps of:

• providing a first generally cylindrical screen having a side, a first end and a second end and means for breaking lamps therein;
• mounting a second generally cylindrical screen having a longitudinal axis, a side, a first end and a second end, generally concentrically around the
• first screen for rotation with the first screen about the longitudinal axis;
• mounting a generally cylindrical tube concentrically around the first screen, between the first and second screens;
• the first screen, second screen and tube being mounted on a longitudinally downward slope from the first ends to the second ends of the screens;
• providing a helical band encircling the first screen and being disposed between the first screen and the tube;
• rotating the first screen, second screen and tube about the longitudinal axis;
• placing lamp components in the first end of the first screen such that as the screens rotate, metal lamp components roll downward toward the second end of the first screen, the glass and powder pass through the side of the first screen to the tube and are carried upward by the helical band toward the first end of the second screen where the powder and glass fall to the second screen, the powder passes through the second screen and the glass rolls downward toward the second end of the second screen;
• and
• collecting the metal components at the second end of the first screen, the powder below the second screen, and the glass at the second end of the second screen.
