Depending on the raw materials used, a wet grinding stage with dry pre-grinding processes can be required for the raw materials prior to the synthesis. The CGS and s-Jet® fluidized bed jet mills can be used for the dry grinding. For the wet grinding, the Zeta®, Neos or Zeta® RS agitator bead mills are used, depending on the required...

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: d 50 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 …

The rare earths, or rare earth elements (REE), are a relatively abundant group of elements consisting of scandium, yttrium, and the 15 elements of the lanthanide series of the periodic table. Scandium (Sc) is the lightest rare earth element. Scandium is present in crustal rocks in amounts greater than lead and precious metals, but it rarely ...

Alumina Balls and Satellites. Union Process is the one source for 90%, 94%, 99.5% and 99.9% alumina media. 90% alumina is available in satellites and rod/cylinders. 94% alumina balls have excellent wear resistance with higher impact strength to save running costs with less contamination. They have great wear rate generally better than 90% or 99 ...

The recovery of Al was increased by mechanically grinding the raw material in a planetary ball mill, and the recovery gradually increased with increases in the grinding time. For example, final Al recoveries of around 8% and 75% were obtained from the 15 min ground and 4 h ground materials, repsectivley.
