Reclamation of sand is an important step in reducing material and disposal costs in a foundry. Utilizing General Kinematics proven VIBRA-MILL® attrition mill, foundries can successfully reclaim sand to 20 mesh with original grain size distribution and corresponding reduction in L.O.I. With proper addition of new sand, reclaimed material is clean and ready for new mold production without further attrition.

The VIBRA-MILL® can be fed in a steady controlled rate from a vibrating feeder or conveyor, belt conveyor, or by intermittent batches from front end loader, floor sweeper, etc., providing the batch does not exceed the volume of the VIBRA-MILL® tub.

The controlled vibration of the VIBRA-MILL® is applied so that the sand is subjected to agitation, tumbling, abrading, and grinding, and this combined action reduces the sand lumps to original grain size and distribution. During the course of the lump reduction, the fine sand grains move toward the rear of the tub where, when reduced to a specific size, they pass through a primary scalping screen and then across a secondary screen for final sizing. Provision for air separation of “fines” is incorporated into this secondary screen.

Foreign material such as sprue, core rods, and other items which will not pass through the primary screen are automatically purged for the mill during a “reject unloading cycle”. During this cycle, the direction of motion is reversed so that unwanted material discharges out the front of the mill through an air operated discharge gate.

GK’s VIBRA-MILL® is available in various configurations depending on your application. For more information about our family of VIBRA-MILL®S, click one of the links below:
