BULK MATERIAL COOLING DEVICE FOR COOLING HOT MATERIALS THAT ARE TO BE COOLED

摘要

The invention relates to a device for cooling bulk materials, particularly hot cement clinker, comprising a fixed ventilated cooling grate (11) and moving push elements (13a-13c) and having an increased service life. According to the invention, the push elements (13a-13c) are embodied in the form of hollow bodies and are cross-flown by a cooling medium (10) and are therefore cooled internally.
