Resin Sand Processing Equipment

ResinSand Processing Equipment

The resin sand processingequipment layout shall be appropriately formulated according to the castingplant layout, technologic property and production requirements. Its processflow is composed of used sand recovery, used sand crushing and regeneration, used sand magneticseparation and screening, used sand air separation andthermoregulation, new sand system, (new) used sandstorage, sand mixing, sand molding, core sand making,etc.

1. Used Sand Recovery
The used sand and scattered sand are conveyed to the sand silo by the conveyor after theirseparation with castings and sand box through the shakeout. The magneticsubstance will be separated by the suspension magnetic separator, belt-typepermanent-magnet separator and other magnetic separation equipment.

2. Used Sand Crushing and Regeneration
The sand lump in the sandlump silo is fed into the crusher evenly and quantificationally through thevibrating feeder, and will be regenerated successively through the roastingfurnace and regenerator after crushing and screening, and finally be conveyedinto the heat sand silo by the conveyor. The magnetic substance will beseparated from the used sand through the magnetic separation equipment. The usedsand will have the preliminary cooling and dedusting through the induction fanand dedusting pipeline.

3. Used Sand Air Separation and Thermoregulation
The hot used sand containingmicro powder is evenly fed by the curtain type distributing device. The micropower is drawn out by air separator. The sand will flow into the sandtemperature regulator and have the heat exchange operation. Finally, thequalified used sand that can reach the required temperature will be conveyedinto the used sand silo by the conveyor.

4. New Sand System
The new green sand will beconveyed into the new sand silo by the conveyor after being dried by the newsand drying system with three return strokes.

5. Sand Mixing, Sand Molding,Core Sand Making
After being matched in a certain ratio, the new and used sand will be mixedaccording to the technical requirements to produce the qualified molding sandthrough the self-hardening sand mixing machine. The qualified sand will then befed into the sand box or core box. After hardening, molding, mold modification,coating and surface drying, the qualified sand will be conveyed to the pouringprocess. After the castings are cooled to the required temperature, thecastings will have the shakeout operation, and the used sand will be recovered.
