In a method of compaction of a powder (P) by means of nip rollers (2, 3) the powder (P) is transported at a supply speed to the nip rollers (2, 3) and friction between at least one of the nip rollers (2, 3) and the powder (P) at said nip roller (2, 3) is determined. Depending on the friction the rotational speed of at least one of the nip rollers (2, 3) is adjusted. The supply speed of the powder (P) to the nip rollers (2, 3) as well as the distance between the nip rollers (2, 3) are maintained substantially constant. |
