  • Device for selectively dispensing limestone for a regenerating oven and process for selectively loading limestone in a regenerating oven using such device
    Patent number: 8360709
    Abstract: A selective dispensing device (1) is disclosed for limestone in vats (5a, 5b) of a regenerating oven adapted to arrange limestone with greater sizes next to an external wall (7a, 7b) of the vats (5a, 5b) and limestone with smaller sizes next to an internal wall (8a, 8b) of the vats (5a, 5b), comprising at least one mobile bulkhead (11) connected to a drive shaft (13) rotating around a rotation axis (X), such rotation being driven by an actuator system and the mobile bulkhead (11) being able to rotate around the rotation axis X to be alternatively inclined by a first angle (?) and by a second angle (?) with respect to reference plane (Z).
