Green sand reclamation line is a vortex centrifugal mechanical regeneration device. The old sand falls on the regeneration disk rotating at a high speed through the quantitative device, and is thrown to the surrounding wear-resistant rings under the action of centrifugal force. After being removed, the regenerated sand falls between the wear-resistant ring and the regeneration disk. At the same time, the fan on the same axis as the regeneration disk blasts upward, forming a strong air flow to boil the falling sand, air separation, debonding film and dust To obtain recycled sand that meets the process requirements. After the old sand treatment, the content of dead clay is low, the amount of new sand added is small, the mixed sand has high wet compression strength, and good fluidity and permeability.
The advantages of this line:
After the used clay wet sand is properly sand-treated, most of it can be recycled. ②The casting sand mold has a short period and high efficiency. ③ The mixed sand mold can be used for a long time. ④ After the sand mold is solid, it can still tolerate a small amount of deformation without damage, which is very beneficial to the draft and the lower core.
