3.2 Working conditions
(1) Requirements for material grinding
For aquafeed with an extruder, the mixing homogeneity and ground particle size of feed mash
should be guaranteed. For aquafeed produced by different die holes, the requirements to the
granularity of feed mash are different. The minimum requirement of raw material is shown in Table
3-2:
