Polyurethane rubber is exclusively used as lining in free-fall mixers. It gives a much lighter mixer, less burnt concrete and longer life compared to ordinary black wear rubber.

The polyurethane rubber is completely insensitive to, for example, mold oil, which means that our sealing ring has a much longer service life than the equivalent in ordinary rubber.
The three-column lining has a 3 mm perforated plate cast in 1.5 mm from the bottom of the plates, to ensure installation and to prevent concrete from being able to work its way behind the lining.
