Title:
COOLER FOR COOLING HOT PARTICULATE MATERIAL
Document Type and Number:
WIPO Patent Application WO2006040610
Kind Code:
A8
Abstract:
Described is a cooler (1) for cooling hot particulate material which has been subjected to heat treatment in an industrial furnace such as a rotary kiln (2) for manufacturing cement clinker, which cooler (1) comprises a supporting surface (13) for supporting a bed (24) of material, said supporting surface (13) being made up of a number of elongated, parallel conveying lanes (14-19) which can be moved back and forth in their longitudinal direction, and being jointly moved in the direction of conveyance of the material and individually or in groups in the opposite direction, and an underlying compartment (11) from which cooling air is led up through gaps in the supporting surface (13) for cooling the hot bed of material. The cooler is peculiar in that it comprises means (22) for providing local, vertical displacements in the bed of material. As a result, the cooling efficiency will be significantly improved since the clinker material is prevented from sticking together to form large lumps. This is due to the fact that any early-stage formations of lumps will be stopped in that the bed of material is locally subjected to vertical displacements, thereby breaking up agglomerated pieces of material.
