Sand Preparation

Specializing in the field of molding sand preparation and control, Simpson builds on more than 110 years of experience providing innovative, integrated technologies with uniquely effective performance to the world's metal casting industry. 

By continuously developing a full range of proven, integrated sand preparation and control technologies, Simpson can benefit any size or type of foundry by providing a complete solution from a single source that best:

  • Provides consistently high-quality sand preparation system performance with minimal process variation.
  • Minimizes the total cost of operation in terms of supervision, energy, raw materials and maintenance.
  • Minimizes the total capital cost to acquire and install the equipment.

These benefits create value for a foundry by enabling it to produce molding sand which maximizes the potential of their casting plant to produce high value, high profit metal castings. 

Simpson Hartley Compactability Controller

Hartley Online Control System

Inline automated sand testing; sends signals to muller to reduce variation in green sand.
Simpson Speedmullor

Simpson Speedmullor

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.
Simpson Multi-Cooler

Simpson Multi-Cooler

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

Simpson Mix-Muller

Energy efficient mulling for the highest quality prepared sand. Providing better consistency and control.
Simpson Multi-Mull

Simpson Multi-Mull

This technology produces larger volumes of molding sand at a lower cost of installation and operation than any other mixer in the world.
Simpson Hartley Dosing System

Hartley Dosing

Designed to be used and integrated together with Hartley Model 2502-L1 or 2552-B1 Compactability Controller and relies on the controller for automatic operation.
BFS Dosing

BFS Dosing

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

Rotary Polygon Screens

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

Bucket Elevator

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

Over Belt Aerators

Due to the design of a conveyor mounting, the Aerator can be integrated into an existing system without any problems.
Project Engineering

Project Engineering Solutions

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