  • Device for removing grate screenings
    Patent number: 4509917
    Abstract: In clinker coolers with a thrust grate a small part of the material to be cooled falls through the grate. These grate screenings usually are collected in funnels, let out and carried away. These funnels and transporting devices are housed between high, complicated foundations. In this invention these funnels are replaced by a removal device which moves the grate screenings horizontally through a transfer canal. This eliminates the complicated foundations and the control of the emptying device previously used.
