Precious Metals and Rare Earths

In addition to gold and silver, platinum metals such as mercury and rhenium are also counted among the classical precious metals. At room temperature in air, these elements either do not corrode at all or do so extremely slowly and to a very slight degree. Although the quantities of gold and silver in the Earth's crust are small, their existence has been known since ancient times. This is due to their precious character, their purity and the fact that they can be extracted from ore at a relatively low temperature. Since antiquity these metals have been used to produce jewelry and coins.

Contrary to the name rare earths, elements of this group are found in the Earth's crust even more frequently than some of some precious metals. These elements are termed "rare earths" because they were first discovered in rare minerals and were isolated from them in the form of oxides. The term "earth" is an old chemical term for oxides, i.e. compounds containing oxygen. The chemically-similar elements of the third group of the periodic system (with the exception of actinium) and lanthanides are considered rare earths.


Dry Grinding

Products & Solutions in the field of Dry Grinding
CSM Classifier Mill

The dynamic air classifier integrated into the grinding chamber housing of this fine impact mill manufactures fine particle sizes with a defined maximum particle size limitation. Internal classification of the coarse material results in a more stable and energy efficient process than a mill with an external classification circuit. Applicable for finenesses from 10 to 150 µm (d97).

Machine sizes with drive capacities from 1.5 - 250 kW and air volume of approx. 50 - 26,000 Nm³/h.

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.

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.

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.
