Presentation of a basket mill with annular gap technology for fine grinding up to nanoscale. 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.
Structural expansion 6: New offices and a canteen
Construction of a office building with modern workplaces. A canteen for all employees will follow.

Structural expansion 3: Construction of new offices
Construciton of new offices and the characteristic blue main entrance . The new climatic offices are epquipped with modern furnitures and computers.
Presentation of the new construction series KREIS-BASKET-MILL® on the occasion of the MECS 2005. High performance mill for fine grinding in batch production! Batch sizes of 2 - 2000 litres useful volume.
Structural expansion 2: New production hall
Building of a further production hall with 3000 m² hall area in order to be able to adapt the production capacity to the increased demand again. This is so far the biggest expanison since the construction of the current company building from 1982 till 1983.
Dispatch of the 3000th KREIS-DISSOLVER® after 40 years.
Development of the latest construction series called "Large-scale dissolver" KDV 2000 - Production and dispatch of the largest KREIS-DISSOLVER® ever manufactured.
Double Suction Disc
NIEMANN was granted the patent for the new development "Double Suction Disc ". This innovation guarantees reduced wetting times and improved dispersion results - another milestone in the history of the constant and successful development of the KREIS-DISSOLVER®!EURO-Patent-Nr. 0896834.
Frank Niemann entered the company
1998 Frank Niemann became the managing shareholder of the company.
Structural expansion 1: Growing production area
Building of a new factory with a production area of approx. 3000 m² in order to meet the increasing demand both at home and abroad.
In addition to the above-mentioned patent Gerhard Niemann invented the current-dependent electronic speed control with the possibility of presetting the speed limit, patent no. DE 3221080 C1.
Delivery of the 1000th machine.
NIEMANN granted the licence for production of dissolvers to Netzsch in Selb/Bavaria until 1985.
Speed control depending on viscosity
Gerhard Niemann invented the speed control depending on viscosity for reproducible dispersion qualities, patent no. 1.588.600, which paved the way for the world-wide success of his company.
First paint mixer
The fire in the lacquer factory of his friend caused Gerhard Niemann to manufacture a small "paint mixer" (dissolver) as a favour. This aroused the interest of local lacquer factories and they wanted to use the newly-developed speed adjustment technology by friction-vario gear, too, instead of the manual speed adjustment by handwheel wich was usual until then.
Restructuring of the company: Gerhard Niemann started the development and manufacturing of large-scale incubators for poultry-breeding and the production was changed from timber production to metalworking.
Wilhelm Höcker founded the today's company as a cabinetmaker's workshop, which was continued by his son-in-law, WILHELM NIEMANN.
