How does the physical appearance of polymer particles affect their applications?

Previously, during an internship at a chemical plant, I noticed that their polypropylene particles were all spherical in shape. Now, however, the polycaprolactam particles produced by our company are cut into oblate cylindrical shapes using a pelletizer. I wonder what considerations there are regarding their physical appearance. How are spherical particles made? Which is easier to produce: sliced particles or spherical ones? Thank you very much
It is determined by the granulation equipment; the size and shape of the pellets are related to the type of equipment used. Additionally, it should also meet the requirements of downstream post-processing equipment.
