In the Thermal Reslin Sand Reclaiming Process there is no possiblity to use sand to produce any cores. It will increase the oolitic percentage and a subsequent increase of acid demand. With a high acid demand it will result in a high absorption of resin in cores production. “Good Regenerated Sand” - Silica Content: Minimum 96%-97%
- Fines (any particle with diameter <106 μm): Less than 1%
- L.O.I. (in average): 0.05%
- Mixture Bench Life: 1.5 hour
- Cores Lab. Resistance (Compression) as it is: 85 kg/cm²
- Cores Lab. Resistance (Compression) coated: 115 kg/cm²
In the Mechanical-Thermal-Mechanical Reclaiming Process there are no issues with using regenerated sand to produce complicated cores. But it will reduce oolitic valuess to less than 1.5% with it operating at 24 tons/hour. And the core resistance will be similar to new sand. The differences between the Thermal-Mechanical Process and the Mechnical-Thermal-Mechanical process is that the Thermal-Mechnical Process has 97% of silica instead of 98.5% silica. There is also a 78% efficiency rate instead of 60% in which there is less quantity of new sand required. And finally there is a 5 to 10% less core resistance to the Thermal-Mechnical Process. |
