Lumb crusher

comminution of resin-bonded lumbs

In the foundry also known as lumb grinder, lump breaker or sand attrition. The vibratory lumb crusher is used for the comminution of resin-bonded lumbs and core break pieces. The drive is driven by two vibration motors. The sand lumbs are crushed by mutual agglomeration. The sand is removed from the trough via the easily exchangeable, perforated chilled-iron plates to the sandbed floor below.
The vibratory lumb crusher is usually used in sand reclamation plants after the shake-out, but also conceivable as stand-alone solutions.
