Abstract
A long rotary kiln which slopes and wherein the particulate material travels downwardly from the inlet toward the outlet end and counter flowing gas travels upwardly therethrough, is provided with a preheater between the inlet end and the main operational zone. The preheater provides lifting devices at its end farthest from the inlet to deposit the particulate material in the gas stream, and an impingement separator zone at its end nearest the inlet to cause the particulate material to lose its momentum and fall from the gas.
