Sand Preparation

Pre-conditions sand, to lower and reduce variability in sand temperatures. The result - optimal mulling and high-quality, profitable castings.

Energy efficient mulling for the highest quality prepared sand. Providing better consistency and control.

The best features of high-intensity batch mixers in a single design — the mixing performance and energy efficiency of mulling with the productivity of a high-speed, high-intensity mixer.

Delivers high-volume, consistent molding sand with exceptional efficiency — helping foundries achieve greater output with lower installation and operating costs.

Our advanced muller options are designed to deliver optimal sand conditioning through intense shearing, blending, and clay activation.

Real-time control with full traceability and trend visibility—eliminating the guesswork from your sand system.

Designed to be used and integrated together with a Simpson Hartley Compactability Controller and relies on the controller for automatic operation.

Designed to provide continuous dosing of dry materials (primarily bentonite clay) to a continuous cooler or continuous muller in a fully automated system.

Engineered to meet each foundry’s needs with varying height ranges, bucket sizes, pully head sizes, and capacities.

Designed to provide continuous screening of foundry return sand in a green sand system.

With its conveyor-mounted design, the Aerator easily integrates into existing systems.

With decades of experience, Simpson provides Project Engineering Solution options from our German Engineering Office.
