Sand Slinger

sand slinger

[′san ‚sliŋ·ər]
(mechanical engineering)
A machine which delivers sand to and fills molds at high speed by centrifugal force.

Sand Slinger

 

a machine designed to feed and compact molding sand in a casting mold. The basic working part of the sand slinger is the sand-slinging head, a housing that contains a rotor with a blade. The molding sand is fed by conveyor to the blade, which rotates at 1,500 rpm, and the somewhat compacted lump of sand is thrown onto the surface of the casting pattern. The molding sand is compacted in layers during consecutive movements of the head.

Sand slingers may be stationary or movable. The latter moves along a track that has flasks along the sides. Sand slingers have capacities of 5–50 m3/hr.
