Simpson Technologies (Deutschland) GmbH

In small to medium-sized sand systems or difficult mixing applications, versatility is critical. The Mix-Muller has been carefully designed and proportioned to achieve maximum performance, versatility and energy efficiency in these types of applications.

Description
Medium-speed, high-intensity, muller-type mixer for batch operation.

Application
Small- to medium-sized sand preparation systems, and the most difficult mixing applications.

Features

• Adaptive tooling
• Energy efficiency
• Larger batch and longer available cycle
• Rugged design

As foundry sand preparation and molding plants become increasingly high-speed and quality-oriented, the control of return sand temperature is essential. the Simpson Multi-Cooler is specifically designed to provide the mixer group with sand that is cooled to temperatures that allow optimal mulling, premixed to eliminate return sand variations and with a moisture content controlled within tight tolerances. The result is optimal mulling and high-quality, profitable castings.

Description
Continuous sand cooler and pre-conditioning system operating on the principle of evaporative cooling.

Application
Sand systems with return sand temperature above 49°C and/or wide variations in return sand properties.

Features

• Pre-mixing with back-blending and controlled retention
• High-efficiency cooling to below 49°C or 10°C over ambient
• Discharge moisture of 2.0% +/-0.2%

In medium- to large-sized sand systems, higher volumes of throughput demand greater productivity from the sand preparation plant. The Speedmullor® is carefully designed and proportioned to achieve maximum mixing performance and energy efficiency while still providing some versatility in applications typical to these sizes of sand systems.

Description
High-speed, high-intensity, muller-type mixer for batch operation.

Application
Medium- to large-sized sand preparation systems that still require some versatility in throughput or product.

Features

• The original Beardsley & Piper Speedmullor
• High productivity
• Smaller batch and shorter cycle times
• Secondary cooling
