How are animal feed pellets made

 

 

Many farmers mistakenly believe that feed pellet production is simply "crushing and pressing," but this is far from the truth. From the moment raw materials enter the production line to the formation of a uniformly mixed powder, this series of fundamental processes forms the first line of defense in ensuring feed quality. Negligence in any step can lead to nutritional imbalances and negatively impact animal growth. The initial stages of animal feed pellet production mainly include four core steps: raw material screening, crushing, batching, and mixing, each with strict operational standards.

 

Raw material screening is the primary step in removing impurities and ensuring safety. Whether it's concentrated feed like corn and soybean meal, or roughage like straw and hay, all materials must undergo dual screening using vibrating screens and magnetic separators. The mesh size of the vibrating screen needs to be adjusted according to the type of raw material: 8-10mm mesh for corn and soybean meal to remove stones, soil, and other impurities; and 15-20mm mesh for straw and hay to separate weeds from dead stalks. The magnetic separator is installed after the screening machine, using a strong magnetic field to adsorb metallic foreign objects in the raw materials, preventing damage to the equipment during subsequent crushing stages and preventing metallic impurities from entering the feed and harming animal health. A feed mill in Shandong province once omitted the magnetic separation process, leading to frequent damage to the hammer mill's grinding equipment, increasing monthly maintenance costs by nearly 10,000 yuan, and even resulting in the death of broiler chickens from ingesting metal shavings.

 

The core of the grinding process is controlling the particle size of the raw materials to ensure the full release of nutrients. Different animals have significantly different requirements for raw material particle size. Piglet feed requires corn to be ground to at least 80 mesh, with a particle diameter of less than 0.18 mm, for easy digestion and absorption. The choice of grinding equipment must also match the needs. Claw mills are suitable for concentrates due to their high grinding efficiency and uniform particle size; hammer mills are used for coarse feeds, breaking down coarse fiber structures through high-speed rotating hammers. Particle size must be monitored in real time during grinding, using a standard sieve for testing. If the particle size does not meet the requirements, the sieve aperture or feed speed of the grinder needs to be adjusted.

 

Ingredient batching and mixing are key to achieving nutritional balance. Ingredient batching must be strictly performed according to the feed formula, using an electronic batching scale for precise weighing, with an error controlled within ±0.1%.
