Cleaning machine for the metallurgical industry DUCTA-SPRUE®

for foundry applicationsrotary drum

The DUCTA-SPRUE® Rotary Sprue Drum combines innovative patented rotary technology with GK’s proven vibratory material transfer equipment to give you a long-lasting, easy to maintain solution for processing sprue, gates, and core butts. Users report that the direct savings resulting from the cleaning of gates, risers. runners, flash, fins, run-outs and other sprue, before charging them into a melting furnace, has repaid the cost of the General Kinematic DUCTA-SPRUE® Sprue Mill and all accessory feeding and handling equipment in under one year. Charging cleaned sprue into a cupola reduces the required additives in some cases from 4% to less than 1%. This results in substantial savings in coke consumption, faster melting, less slag to handle, reduced deterioration of cupola linings, and easier cupola control. Cores from the shakeout / knockout can be processed with the sprue, releasing rods, gaggers, arbors and wires for picking. OPERATION Material can be loaded into the DUCTA-SPRUE® rotary mill in a variety of ways. Once inside, the material is subject to a tumbling action which removes the sand from the metal and breaks up large core lumps. The sand passes out through slots in the shell while the cleaned metal parts are discharged from the end of the barrel. Air is vented from the screen section, using air drawn in from the inlet and outlet of the barrel to prevent the escape of dust into the foundry. With the aggressive tumbling action, sprue will break at the weak areas, providing smaller material for charging.
