## Abstract

An improved disc dryer for aggregate material which operates by rotating and impacting a tilted pan which holds the material being dried. Increased capacity is attained by transverse stabilizers on the impactor assembly, adjustable pressure air shock mounts for variable amplitude control of the impactor assembly, sets of dual support wheels upon which the pan rotates a reinforced support tract on the underside of the pan, and an adjustable feed box for supplying material to the pan at varying locations.

## Claims

### Claim 1

In a dryer for aggregate materials of the type comprising a pan with retainer sides, the pan being oriented at an angle to the horizontal, being rotated upon wheels by which it is supported and being impacted by an impactor assembly to induce vibration, the improvement comprising:
a feed box for supplying material to the pan, the feed box including a material exit means which provides the material leaving the feed box with some horizontal motion so that the material does not fall directly below the feed box, and further including means to rotate the material exit means around the center axis of the feed box so that rotation of the material exit means moves the location of material entry into the pan.

### Claim 2 (depends on 1)

The dryer of claim 1 further including means to increase the height of the material exit means above the pan.
