Polyurethan Rotor flotation cell

Flotation is a physico-chemical separation process that is used in mining to separate fine-grained solids (e.g. calcium carbonate). The solid is stirred in a mixture of water and various chemical additives, rises and can be extracted.

In the flotation process, wear parts such as the rotor or stator are subject to high mechanical and chemical loads. This is exactly where the very good mechanical and chemical properties of polyurethane come into play. Compared to rubber linings, our polyurethane coatings have a significantly longer service life and thus significantly reduce operating costs.

Because we develop polyurethane recipes ourselves, we can specifically cater to your process with the polyurethane system (MDI, TDI, ether, ester, polycarbonate) that promises the longest service life.
