Ceramic Pigments

Many decorative paints and glazes are used to refine the surface of ceramic products such as earthenware, stoneware and porcelain. In addition to frits, the basic components of the paints and glazes are primarily special pigments. 

These ceramic paints are usually inorganic compounds, mostly oxides, silicates, aluminates and metal borates. One can distinguish between underglaze colors, inglaze colors (as in-glaze and high-fire paint), and onglaze colors (enamel, enamel paint). Common ceramic colors are chrome green, cobalt blue, iron red, vanadium-zircon stains and zinc paint. 
In contrast to the crystalline, porous base material, this type of surface decoration produces a glass-like, cohesive surface layer. 
Ceramic pigments are usually finely ground in alcohol as the solvent in order to prevent oxidation and, with it, a reduction in quality. This places high demands on the design of the machines and the materials used to build them.

s-Jet® Steam Jet Mill

The s-Jet® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d50 0.2 µm) can now be achieved with fluidized bed jet mills. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet® System uses superheated steam as its milling gas.

CGS Fluidized Bed Jet Mill

The combination of an air jet mill and a dynamic air classifier represent fine dry grinding in perfection. The highest of final finenesses with an exact maximum particle size limitation become reproducible. The development of the new e-Jet® and s-Jet® grinding methods constantly yields new, interesting areas of application, both economically and technically. Applicable for finenesses from 1 to 70 µm (d97).

Machine sizes available for grinding air volumes from approx. 50 to 12,000 Nm³/h.

ConJet® High-Density Bed Jet Mill

The ConJet® high-density bed jet mill is a spiral jet mill combined with a patented dynamic air classifier. This classifier enables the ConJet® to achieve highest finenesses independent of the product load, and therefore also highest throughput rates. Applicable for finenesses from 2.5 to 70 µm (d97).

Machine sizes available for grinding air volumes from approx. 50 to 2,400 Nm³/h.

s-Jet® 25 Laboratory-Scale-Steam Jet Mill

The s-Jet® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d50 0.2 µm) can now be achieved with fluidized bed jet mills. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet® System uses superheated steam as its milling gas.

CGS 10 and CGS 16 Fluidized Bed Jet Mills
