Because of their poor physical properties, virtually all dry, powder-like raw materials can only be granulated by means of roller compaction with mechanical force without binding agent and with only slight thermal stress.

The powder feed to the press rollers is normally carried out by means of a feed screw, which compared with rotating rollers must be sealed both on the powder side as well as at the roller faces.

The roller gap seal
There are in principle two options: The most frequently-used seals are so-called static slit diaphragms or check plates. There is also the option of sealing the roller gap with a ring shoulder roll, also called a dynamic slit diaphragm, dam-ring, or DP roller.
