The Shakeout Deck Attrition Mill Unit not only acts as a shakeout deck, but also includes an integral attrition mill section. The output of this unit is grain size and ready for cooling and classification.
The terms “Sand Reclamation”, “Shakeout Deck”, and “Attrition Mill” are related to foundry processes where used sand from molds or cores is cleaned, reconditioned, and reused in casting operations.
Sand Reclamation
Purpose:
Sand reclamation is the process of recovering and reconditioning spent foundry sand for reuse. This helps reduce the environmental impact of waste disposal and lowers the cost of purchasing new sand.
Methods:
Mechanical Reclamation: Removes impurities by grinding, scrubbing, or shaking the sand.
Shakeout Deck Attrition Mill
Purpose:
A shakeout deck attrition mill is used to separate casting molds from the sand after the casting process. iIt used to further refine and clean reclaimed sand. It breaks down sand agglomerates and removes binders or debris.
How It Works:
The casting along with the sand is placed on the vibratory shakeout deck.
Vibrations loosen the sand from the casting.
Sand falls through perforated screens for further reclamation.
The sand is subjected to mechanical friction, typically using rotating paddles or blades.
The friction strips coatings or residual binders from the sand grains, improving their reusability.
Shakeout Deck Attrition Mill Advantages
- No pit required (less clean-up).
- Low level loading for better ergonomics and productivity.
- Balanced motor system for weight distribution.
- Reduces sand from lumps to grain size in a single unit.
- Easy access to vibrator motors.
- Heavy tramp metal is removed through side access door.
- Self cleaning screens.
Shakeout Deck Attriton Mill Features
- Compact design allows for easy installation.
- Easy accessibility for cleaning.
- Linear vibratory motion minimizes spill sand.
- Low level shakeout height enables discharge of molds from roller conveyor or vibratory trough conveyor, feed belt, etc.
- Heavy-duty construction for long production life.
- Modular design for easy maintenance.
