  • Replaceable wear parts for centrifugal pellet dryers
    Patent number: 4896435
    Abstract: Improvements in centrifugal pellet dryers including replacement parts for those areas of a centrifugal pellet dryer that are most subject to wear during normal use when drying pellets. The feed chute, base section and top section with pellet discharge chute are replaceable thereby avoiding the necessity of providing a completely new housing structure or a completely new pellet dryer when the dryer has become worn during normal use. The replaceable parts are substantially duplicative of the parts which they replace and are secured in place by conventional fastening and sealing arrangements.
