Abstract
Apparatus for predrying and preheating pellets involving an oscillating grate extending angularly downward across the predrying section and discharging into a preheating section. The grate is substantially equal in width to the width of the predrying section so that the gas flow area through the predrying section is substantially less than the gas flow area through the preheating section. Further, the grate includes a plurality of spaced members positioned to form a gas flow velocity therethrough greater than the gas flow velocity through the preheating section.
