Fitzpatrick Roller Compaction

Contained Chilsonator System

Fine powders can be processed into densified sheets in the Chilsonator® by the use of mechanical pressure exerted on two counter rotating compaction rolls. The densified sheets can then be granulated to any desired mesh size.

The basic concept, as illustrated in Figure 1, is to force fine powders between two counter rotating rolls. As the volume decreases through the region of maximum pressure, the material is formed into a solid compact or sheet.

Some of the factors controlling the compaction process are roll surface, diameter, peripheral speed, separating force or pressure capabilities, feed screw design and basic compaction characteristics of the material being processed.
