• The urethane (cold box) process is very susceptible to clay and if not removed will reduce bench life and strength.

The Tinker Omega Sinto solution

• Avoid the Traditional process combining pneumatic scrubbing with thermal processing.
• High capital expenditure running and maintenance cost.
• The application of USR secondary attrition system to remove greensand additives for reuse
• Remove Active and Dead Clay
• Reduced capital cost
• Reduced maintenance and running cost
