Are you Under-mixing or Over-mixing your Green Sand? Enter, the Wet Tensile Strength!
In the modern sand plant,muller/ mixer is the heart of the operation, but it is also a bottleneck for energy and throughput. Many foundries rely on historical "rules of thumb" for mixing times (e.g., "90 seconds per batch") without validating if the clay has reached its full potential. This article outlines a practical methodology for using Wet Tensile Strength (WTS) to determine the exact point of bentonite activation, allowing foundries to optimize cycle times.
