Rotary Separator / Sprue Mills High rotary tumble action crushes core butts and cleans the sand off gates, runners, and sprue. Melting efficiency is increased with clean and condensed melting stock. The sand is recovered and slag handling and disposal costs are greatly reduced as well. The machine eliminates shot blasting of the melt returns and can process large mold/core lumps. Additional savings include the elimination of the cleaning room bottleneck as well as the need for expensive jaw crushers. DIDION Rotary Separator / Sprue Mills require less energy, less maintenance on shot blast equipment, and install easily. By keeping the sand in the sand system, the machines also significantly reduce clean up costs and keep one's foundry much cleaner.
