[vc_row][vc_column][vc_column_text]Indirect classification makes use of the different behaviour of particles depending on their grain size or mass, when they are positioned in an airstream (pneumatic classification) or in a liquid flux (hydraulic classification).[\/vc_column_text][\/vc_column][vc_column][vc_column_text]Pneumatic classification<\/strong> consists of carrying out a particle sized cut on a powdered and dry material suspended in a gas set in motion (generally the air) so as to obtain two distinct fractions \u2013 fines and coarse-grained particles. The separation principle is based on the effective (and not real) size of the particles by difference in speed and fall in a gas. This type of classification is carried out on particle sizes generally ranging between 1 and 100 \u00b5m.<\/p>\n

The CTP has air separation equipment functioning at laboratory scale and at pilot scale.[\/vc_column_text]\n
