The automatic distance adjustment of the pan grinder impellers to the die surface allows the material friction process (with heat factor) for compaction to be shifted to the pan grinder chamber instead of in the die bores and enables changes in the quality of the pellets during operation. This friction shift enables significant tool savings by eliminating the need for adapted die thicknesses for a fixed pellet quality. With the automatic distance adjustment, a pelletizing process can be carried out that produces a homogeneous final pellet from different input pellets, which is important for the pellet and pellet quality. The frictional conditions make it possible to break down composite materials in a way that would otherwise be difficult. The latter process is mainly used with short die holes of 10 – 16 mm.
