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.

Heinrich Wagner Sinto offers a fine sand slinger that can transform any quantity of normal molding sand into fine sand and apply it directly onto the pattern surface.
New green sand core equipment, a fine sand slinger and a green sand middle mold system were highlighted at the Heinrich Wagner Sinto booth (Roberts Sinto in the U.S.).
For decades, the vast majority of cores have been machine produced using either a jolt table, shell core, sand slinger or core blower.
A sand slinger uses the downward force of sand, propelled by rotating vanes, to achieve the required level of sand compaction in the corebox.
