Regeneration instead of disposal

For more than 20 years, sand regenerated plants have been sold under the name of KGT. After the take-over by Webac, this know-how was successfully developed further, and today it offers foundries an economically and ecologically sound option for re-using foundry sand multiple times. Circulating foundry sand means a reduction in the requirement for new sand, in auxiliaries, and in the amount of spent sand for disposal.

The effectiveness of sand regeneration depends on how precisely the plant concept is tuned to the prevailing circumstances. Factors such as sand quantity, composition of the sand, binder systems used, and thermal stress to the sand are basic information which has to be taken into account in designing the plant. We supply not only individual regeneration plant components, but also complete self-contained systems.

The modern control systems guarantee completely automatic operation of the regeneration plants, with automatic recording of all relevant process data. This is important for quality control. The controls systems not only ensure largely intervention-free operation, but also a consistently good quality of regenerated material.
