Leaders in industrial mixing and foundry sand technology



Everything you need to create the highest-quality, precision-blended products

From world-leading intensive mixing technology to optimized solutions for the preparation, reclamation, and testing of foundry sand. Which now also includes equipment digitally enabled with Monitizer’s industry-leading IIoT technology, allowing customers to visualize, analyze and act on performance data to optimize processes.

Robust, energy efficient and cost-effective - our technology goes the distance.

Sand Preparation

  • Multi-Cooler: Pre-conditions sand, to lower and reduce variability in sand temperatures.
  • Mix-Muller: Energy efficient mixing for the highest quality prepared sand.
  • Speedmullor: The mixing performance and energy efficiency of mulling with the productivity of a high-speed, high-intensity mixer.
  • Multi-Mull: Technology that produces larger volumes of molding sand with at a lower cost of installation and operation.
  • Hartley Controller: Inline automated sand testing; sends signals to muller to reduce variation in green sand.

        Sand Reclamation

        • Pro-Claim: Energy efficient sand reclamation that lowers waste and provides significant raw material costs savings.
        • Test your material before making a decision.

        Customer testimonial

        “When we first started we were using 40% reclaimed sand and 60% new sand. Currently we’re using 95% reclaimed and 5% new sand – Foundry Manager
