Sand Collection Grate

The Sand Collection Grate is a critical component of automated shakeout units used in foundry applications. It consists of a rigid, perforated metal structure installed beneath the shakeout deck that allows sand and fine particles to pass through while retaining larger castings. This component facilitates the separation of molding sand from cast metal parts after the casting process, enabling efficient sand reclamation and casting collection. The grate's design ensures uniform distribution of sand flow to collection systems while withstanding continuous mechanical vibration and abrasive wear.

The Sand Collection Grate operates on the principle of size-based separation through perforated openings. During the shakeout process, castings are vibrated on the shakeout deck, causing bonded sand to break apart. The sand particles fall through the grate's openings due to gravity and vibration, while larger castings remain on top. The grate's specific opening size (typically 10-50mm) is designed to match the smallest casting dimensions to prevent product loss while maximizing sand recovery.
