Press Release

KLEIN Anlagenbau AG develops and manufactures pneumatic conveying systems, core sand preparation systems and used sand reclamation systems as well as peripheral foundry equipment.

Foundry Equipment made by KLEIN

Almost five decades of experience in international plant engineering make KLEIN Anlagenbau AG the competent partner in the area of pneumatic conveying systems, core sand preparation, sand reclamation and peripheral foundry equipment. The business activities of KLEIN range from consultation to project planning and execution; engineering services, manufacture, installation and start-up as well as training of operating staff and after-sales services complement this profile.

For modern core production KLEIN offers complete systems with the main component, the unique core sand mixer STATORMIX. Thanks to the special design of this mixer with its horizontal shaft and the two-chamber mixing principle, most homogeneous core sand mixtures are achieved in short mixing times. This does in particular apply to the preparation of inorganic sand-binder mixtures, consisting of liquid and powdery components. The preparation of inorganic mixtures in a STATORMIX has proven that considerably less binder is consumed to achieve bending strengthes comparable to those achieved with conventional mixers.

Remarkable features are the tightness of the mixer closure and very short mixing cycles, contributing to avoid moisture loss of the mixed batch. The core sand mixer STATORMIX is equipped with an integrated cleaning system by means of which the mixer interior can be kept clean very well. With three different mixer sizes capacity demands of up to 9 t/h can be met. More than 400 core sand preparation systems with STATORMIX are operated worldwide.

During GIFA 2015 KLEIN will present a complete core sand preparation plant for inorganic binders, including a sand conditioner for cooling/heating and dedusting the sand, additive tanks with disaggregation unit and dosing screw, a pneumatic conveyor for additives, a weighing system for the recipe ingredients, a binder dosing system and a core sand distribution system.

The energy-saving pneumatic conveyor SP-HL was especially conceived for the transport of granular bulk material such as foundry sands. Visitors to KLEIN's booth in hall 16/C11 will see a tandem conveyor SP-HL in action, where two conveyors feed sand into one conveying pipe. With tandem installations like that conveying capacities of more than 20 t/h can be achieved. More than 1000 SP-HL conveyors are operated worldwide. Remarkable features of the SP-HL are its high performance with energy savings of about 40 % compared to conventional conveyors, its gentle transport that saves the grain structure of the sand as well as the minimal wear of the conveying pipes and last but not least its small space requirements.

In addition to the exhibited conveying system for foundry sand, KLEIN also supplies pneumatic conveyors for all other materials handled in a foundry such as bentonite, carbon dust, filter dust, different additives etc.
