Küttner and Savelli | Good reasons for good sand
The fluctuation of molding properties is still the biggest cause of casting defects, as most preparation plants still follow the general standard without taking into account the specific needs of each application.
A particularly even sand can be achieved if test
- the model data are available at the mixer and the recipe is adapted preventively to the product data;
- the model data are available at the shake-out and the burned components are added early in a premixer.
Essential features of the sand preparation:
- Mixer or fluidized bed cooler with the respective advantages during homogenization or cooling
- Premixer for balancing bentonite, carbon and filter dust losses with strongly fluctuating, core-intensive casting program
- Intensive mixer with control of the green sand properties via compactibility and compressive strength
- Return sand moisture measurement and prepared sand tester with integrated calibration routines
- Belt systems and bucket elevators in foundry-like design
- Material balance
- Complete green sand preparartion plants with central control
- Sand coolers, sieves and mixers as single machines
- Moisture measuring instruments and material testers
- Spare and wear parts service
- Company support and advice
Küttner and Savelli have the entire portfolio of foundry machines for sand processing and use this jointly.
