Pellet Mill Vs. Extrusion of Fish Feeds. The process of pelletization happens inside a pellet mill. It involves creating pelleted feeds by compression of raw material, which is in powder form. This compaction happens in the presence of some moisture, temperature and pressure. Pelletized feeds are dense and heavy and thus they sink.
