Abstract
The shaft cooler comprises a plurality of power-driven adjacent horizontal hollow perforated comminuting rolls. An upper section of the shaft cooler is adapted to hold a layer of material from 50 to 100 cm. deep above the rolls. Cooling air is supplied to the interior of each roll to cause it to be discharged into such layer of material. An aftercooling section below the rolls is provided with means for indirect cooling of the comminuted material and has a depth which is several times that of said layer.
