The handling of particles is a general operation concerning a great number of industries for which a process implies a treatment of matter or material: foods, pharmaceutical, cosmetics, chemical. This represents 60-70% of the processes. The materials can be of any type, mineral, organic. The handling of materials is just a transfer from a place to another one, thanks to different devices by operating under different conditions. This insures the transfer of particles from trucks to a bin or from a bin to the unit where the transformation of particles will occur, for example from mixer to bin, or bin to die where compaction or tabletting will occur, or bin to bags.
