Pellet geometry and pellet uniformity both within a batch as well as between batches have a decisive effect on the feed behavior in an extruder. This must be kept in mind in particular when processing pellets on a laboratory scale, since the screws usually have shallow flights.
Collin® pelletizers are characterized by their high precision and reproducible pellets. The ability to adjust blade clearance precisely and observe processing easily are especially noteworthy features.

The basic version is a system with a drive for a pre-defined pellet length of about 3 mm.

Type CSG 171/2

Two independently controlled drives permit infinite adjustment of pellet length from 1 to 5 mm.

This die-face pelletizer employs an eccentric cutting system on a mobile base, permitting fast relocation from one machine to the next.

The unit is optionally available with water cooling, air cooling or a vibrating chute
