Double Brush Aerator

Rotary Brush AeratorThe States Rotary Brush Aerator provides high speed aeration of molding sand for automatic molding machine, tight flask, squeezer, floor molding and other molding operations. It is especially beneficial for aerating prepard sand that has become packed during transport in a bucket elevator. The States Rotary Brush Aerator is a completely self-contained unit that’s designed and sized to easily fit on existing or new 18”, 24”, and 30” flat belt conveyors. Other sizes are available on request to meet ant requirement.

The complete assembly consists of the brush assembly, V-belt drive with TEFC motor, heavy steel frame and housing, belting support plates and asjustable support mountings. The aerator brush is extremely long wearing and consists of States’ exclusive hardened annealed spring steel sprigs that are secured in cast hubs to form a high density brush assembly. High speed rotation of the brush imparts severe shearing and cutting action to the sand for maximum mixing, uniformity and flowability. To increase sand cutting life, the brush assembly is mounted on an adjustable frame which can be lowered as the sprigs wear. The aerator brush assembly is designed for the easy replacement of the sprigs, if necessary. A rubber curtain at the inlet and discharge openings contains the sand and minimizes dust and moisture loss. A simple V-belt and 1200 RPM TEFC motor is included for the unit ans requires very little maintenance. Electrical controls consist of a stater with push buttons mounted in a NEMA-12 dust tight enclosure. The aerator housing is constructed of heavy plate steel and angles for continuous duty operation. Exposed surfaces are protected with primer and then painted with one coat of machinery enamel.
