Japanese Patent JPS613452
Kind Code:
Y2
Abstract:
An apparatus for the treatment of powdery and granular substances, which provides for cooling or heating and/or spraying the substances with liquid or molten addition or treatment elements in a vessel rotationally symmetrical to its vertical axis. The substances to be treated are introduced into a vortex flow at the head of the vessel and then carried along by a substantially axially parallel, downward-moving gas stream and are conducted through a spraying zone in which the liquid or molten elements are sprayed thereon. This flow, after a movement undisturbed over a certain interval, strikes upon a counterflow rising from underneath, the velocity adjustment of which is determined by the sifting effect and/or the staying time. The gases, preferably air, enter the vessel in a tempered state in correspondence to the desired result of the process.
