DUCTA-SPRUE® Rotary Sprue Cleaner / Consolidator

The DUCTA-SPRUE® Rotary Sprue Cleaner / Consolidator utilizes GK’s innovative patented rotary technology to give you a long-lasting, easy-to-maintain solution for processing sprue, gates, and core butts.

The DUCTA-SPRUE® Sprue Mill thoroughly cleans gates, risers, runners, flash, fins, run outs, and other sprues before charging them into melting furnaces.  Reclaiming core and green sand from the incoming material results in a cleaned sprue returned as a charge material reducing slag, improving density, and shortening melting times.

Operation

Once loaded inside, the material is subject to a tumbling action which reduces residual sand lumps and cores, and liberates the sand for removal via the perforated liner package. The sand is carried between the liner wall and the drum body, allowing the cleaned metal parts to discharge from the end of the barrel. Air is vented from a cover above the discharge section to prevent the escape of dust into the foundry. With the aggressive tumbling action, castings can be liberating from the gating, with further consolidation of the gating resulting in a denser material for charging.

Standard and Custom Sizes

General Kinematics offers standard and custom-sized DUCTA-SPRUE® rotary drums. Units include GK’s easy-to-replace LOCK-TITE™ wear-resistant liner system, which is designed to lift and tumble material while screening loose fines. The drum tires are forged steel, supported on forged trunnion rollers. Thrust rollers and standard drive equipment are included with all models.
