The counterflow cooler is an essential device in the feed pelleting process, designed to rapidly cool down hot and moist pellets to near-ambient temperature. By applying the counterflow principle, cool air moves opposite to the direction of pellet flow, ensuring uniform cooling while preventing surface cracking or internal re-moistening.

The vibrating screener, also known as the plane rotary sifter, is a high-efficiency screening and grading machine widely used in feed, grain, food, and chemical industries.

The feed pellet crusher is an essential machine in the pelleting section of feed mills. It is designed to crush large pellets into medium or small sizes to meet the feeding requirements of poultry, livestock, and aquatic animals at different growth stages.
