Nov 01, 1998· In these cases ultra fine grinding is needed as final processing. Ultra fine grinding is a unit operation process where particles are ground to a fineness where 8t)% of the particles are smaller than 1-10 i~n. Mills often used for ultra fine grinding are the attrition mill and the jet mill [1,2].

The Contraplex is a fine impact mill with two driven pin discs. In counter-rotating mode, much higher relative speeds are possible than with the UPZ fine impact mill with only one driven pin disc. The highest relative speed develops at the outermost pin rows and can be up to 240 m/s. The fineness can be adjusted by altering the pin disc speeds.

The Operating Principal P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.
