For extreme fineness requirements Particle Size Reduction Services include the use of air micronisers or batch ball mills with ceramic liners and media for iron free grinding in both wet and dry states.
Wet grinding can be followed by filtering and tray drying to produce dry powders after dissagglomeration.
All the Contract Particle Reduction Services can be followed by further in house facilities which include blending with dry or liquid additives followed by packaging to suit individual requirements in small packs through to one tonne big bags.
With a well equipped laboratory all the usual particle characterisation tests can be carried out included Particle Size Analysis with Malvern Mastersizer.
