NIEMANN presented the KREIS-BASKET-MILL®-RS for the first time to the professional visitors on this year’s European Coatings Show. The new machine variant in the delivery programme of the family business belongs to the category of the basket mills and is especially suitable for the production of pigment pastes, industrial coatings, flexo printing inks and other products, which are difficult to grind. Managing Director Frank Niemann is proud to bring an immersion mill with annular gap technology as first manufacturer at all on the market.

After the successful test phase the first series machine KBM-RS 411 with 45 kW driving power and a container volume of 800 litres was presented on the occasion of the ECS.

The KREIS-BASKET-MILL®-RS offers all possibilities of a classic basket mill and extends these with the advantages of the annual gap technology, with which the finest grinding up to nanoscale is possible. Due to the low grinding chamber volume, up to 60% less grinding media are required. The grinding media movement is made by a rotor with pins, whereby an extremely high energy density can be achieved in the annular gap. The optimised ratio between the cooling surface and the grinding chamber also has a positive effect on the process times during the production of products, which are difficult to grind.
