Abstract
Apparatus for cooling a bed of pyroprocessed particulate material such as lime received from a source such as a kiln, the cooler including a shaft with one or more underlying hoppers through which the material flows as cooling air is forced upwardly therethrough. The invention embodies hoppers with uniform slopes at any given elevation, dual hopper slopes with one being extremely steep, internal flow guiding means, as well as an octagonal or partially octagonal wall configuration and matching scalloped octagonal hoppers. Also included is the concept of providing substantially equal areas of draw in any angular segment about the vertical center line of discharge from a hopper or cluster of hoppers. The resultant is more uniform flow of material down through the cooler and correspondingly more efficient cooling. Alternative embodiments include hopper transition pieces in lieu of the cooling shaft being constructed in an octagonal or partially octagonal configuration.
