Disc Granulation vs. Roller Extrusion Production Lines: Cost Comparison Analysis

Disc granulation production lines use a wet process, rolling materials into pellets within a disc using water or steam. Subsequent drying and cooling equipment is required to remove moisture. Roller extrusion production lines, on the other hand, use a dry process, directly pressing powder into flakes under high pressure, followed by crushing and sieving into granules, completely eliminating the drying and cooling steps. These fundamental differences determine their varying investment costs, operating costs, and product positioning.
