Mechanical Sand Reclamation System
A typical mechanical reclamation system will include the following sequence of components:
Shakeout Deck
Attrition Mill
Elevating Device
Surge Hopper
Magnetic Separator
Agglomerate Screener
Fluid Bed Classifier (Cooling Optional)
Elevating or Pneumatic Transportation Device
Bulk Storage Silo for Mechanically Reclaimed Sand
Dust Collector
Mechanical Reclamation System Offerings
A basic mechanical system includes:
Shakeout Deck / Attrition Mill Combination Unit
Bucket Elevator
Surge Silo/Hopper (suggested)
Classifier without cooling
Control Panel for All Above Items
A basic mechanical reclamation system is a good choice for foundries who:
Shakeout when sand is 250°F or lower
Have throughput requirements not exceeding 6-8 TPH depending on resin system, metal poured, sand:metal ratio, etc.
Do not need to cool their sand prior to leaving the reclamation system
Have few, if any, chills in their molds
Shakeout Deck Attrition Mill Combination units are available in deck sizes of 3', 4', 5', 6', and 7' square. Generally, the maximum mold should be at least 1' smaller than the size of the deck.
Optional Upgrades to basic mechanical systems:
Magnetic Separation
Additional Agglomerate Screeners
Upgrade to a Cooler Classifier to allow sand to be cooled
High Temperature Air Driven Elevators to allow for sand temps above 300-400°F
After the classifier, the sand will generally need directed to a different silo for bulk storage, or back to a daytank for point of use storage. In either case, as there is generally horizontal distance between the classifier and this storage location, a pneumatic transporter is an excellent way to move the sand to its destination.
There are times when a foundry may need a system that has more capability than a basic system. Some examples may be:
Large throughput amounts or very large molds
High temperature of shakeout
The desire for automatic chill removal from the sand stream
Fragile castings that require a modulated shakeout
In these cases, it is very common to change from a shakeout deck/ attrition mill combination unit over to a system that has separate pieces of equipment for shakeout and attrition, as well as often having vibratory lift devices to elevate chunks of sand.
