Core sand mixers
The KLANN core sand mixers are compact batch mixers, which are available in various sizes. They can be emptied by tilting the mixer bin and allowing the core sand to flow out. This avoids the use of flaps or sliders that are prone to failure. The placement of the mixing tool at the base and the shape of the mixer bin ensure the thorough blending of the binder-sand mixture at the lowest energy use.
The mixers are provided with volumetric and gravimetric dosage units.
Core sand regeneration systems
To save unnecessary core breakage disposal costs, KLANN developed a compact core sand regeneration system, which return core breakages or core chips in various stages of preparation to reusable raw sand. After breaking up the core sand conglomerate, coarse impurities are sieved and particulates are separated with an air stream. The prepared sand, which can be estimated at approx. 5 - 10% of the total quantity, is reintroduced to the mixer in small doses with the new sand.
