Shakeout Systems & Casting Handling:
Where Casting Meets Reclamation

A shakeout system (Ausleerstation) is the station at the end of the cooling conveyor where the cooled casting is separated from the used moulding sand that surrounded it. Three architectures cover most of the foundry world: a vibrating shakeout grid (Ausleerrost) that shakes the mould until sand falls through the grate and the casting stays on top; a rotary drum shakeout that tumbles the mould until sand breaks free; and, for delicate castings, a pneumatic shakeout that uses air pulses instead of mechanical shaking. In every case the output is the same: a clean casting moving onward to the cleaning line, and separated sand moving onward to reclamation.

Shakeout is deceptively critical. Undersized shakeout is the most common bottleneck in an otherwise well-engineered line, backing up moulds on the cooling conveyor and stalling the whole foundry. Oversized shakeout wastes capital. Axmann sizes the shakeout based on real mould geometry, cooling temperature at shakeout entry, required sand-to-casting separation quality, and the intake capacity of the downstream reclamation plant. The shakeout station also integrates magnetic separation for tramp iron, primary lump breaking, and a dust-capture hood that prevents silica escape at the noisiest point in the foundry. Casting handling conveyors move the freed casting to the next stage, cooling, pouring and casting handling operate as one integrated system.
