Document Type and Number:
Japanese Patent JP2002538413
Kind Code:
A
Abstract:
The invention concerns a method comprising a step which consists in passing the powder through a unit for reducing (24) the average size of the powder particles, bringing about a modification in the general appearance of the spectrum of the particles, step whereby are retained in the reduction unit so-called coarse particles whereof the size is greater than a predetermined size, or critical size, while so-called fine particles whereof the size is less than said critical size are allowed to pass through. The size of the coarse particles is continuously reduced (in 44) in the reduction unit so as to form particles with a size less than the critical size, or reduced particles, and the reduced particles are distributed in the free flow of fine particles. The method eliminates the problems of clogging, contamination and recycling.
