Shakeout
The JOEST Shakeout is a high-performance solution for the automated separation of sand lumps and castings in foundry production. Especially in wet casting processes, it ensures reliable and gentle material processing – even under high temperatures and mechanical loads.
Its modular design, robust construction, and precisely adjustable vibration parameters allow optimal adaptation to a wide variety of requirements.
The use of high-quality materials such as manganese steel, individually configurable grate systems, and a low-vibration design ensures maximum operational safety while keeping noise levels low. Combined with automated control systems, energy-efficient drives, and ergonomic maintenance concepts, the shakeout becomes a key component of modern foundry operations.
FUNCTION
After excavation, the still in-tact molds are transferred either directly or via a vibrating feeder to the shakeout. There, targeted vibration breaks up the mold, enabling separation of castings and molding sand.
The sand falls through specially designed grate openings, while the casting is conveyed longitudinally. The micro-throw action of the trough ensures gentle and uniform separation without applying mechanical stress to the casting. The sand is then directed to return or sand reclamation, while the castings move on for further processing.
PRODUCT DETAILS
The JOEST Shakeout is specially designed to withstand the harsh conditions in foundries. The trough body is made of torsion-resistant steel profiles that ensure high stability while providing a vibration-optimized design. All wear-exposed components such as grates, side plates, and crossbeams are designed for maximum service life – e.g. by using wear-resistant manganese steel plates and riveted joints.
The system has a modular design and can be individually adapted in width, length, and grate geometry. Depending on the requirements, different grate types with defined hole shapes are used to ensure clean separation with minimal sand loss. Vibration is generated by frequency-controlled unbalance motors, which – in combination with electronically adjustable vibration angles – allow precise adaptation to the shape and weight of the sand lumps.
Thanks to the integrated process control system, various operating modes can be mapped – from continuous to timed or interval-controlled operation. All components are easily accessible for maintenance and are designed for long-term use under high thermal loads.
