**(III) Storage of Raw Materials**

Feed mills store a wide variety of raw materials. To manage this, they use different types of silos, such as tower silos and room silos. Main raw materials like corn and wheat have good flowability and are typically stored in silos. Auxiliary materials such as bran and soybean meal, which tend to clump, are better suited for room storage to prevent clogging during discharge.
**(4) Cleaning of Raw Materials**

Impurities in feed ingredients can affect product quality, damage equipment, and pose safety risks. Therefore, it is crucial to remove them early in the process. The main cleaning equipment includes screens for removing large debris and magnetic separators for iron impurities. These steps help ensure smooth production and high-quality output.
**(5) Raw Material Crushing**

Crushing is a key step that determines the particle size of the final feed. It can be divided into single-stage, multi-stage, and combined processes. Single-stage crushing is simple but may result in uneven particle size. Multi-stage processes improve uniformity by using multiple sieves and crushers. Combined processes integrate different types of grinding machines for optimal results.
**(6) Ingredient Processing**

There are several ingredient processing methods, including manual addition, volumetric feeding, and scale-based batching. Manual methods are used in small facilities, while larger plants often use automated systems. Volumetric and scale-based methods offer greater accuracy and efficiency, reducing human error and improving consistency.
**(7) Mixing Process**

Mixing can be done in batches or continuously. Batch mixing allows for easy formula changes and less cross-contamination, making it widely used. Continuous mixing offers steady operation but requires careful control to avoid residue buildup and contamination between batches. Most modern facilities use automated systems for better precision and efficiency.
**(8) Pelletizing Process**

1. **Conditioning**: This step adjusts the moisture and temperature of the dry powder to prepare it for pelleting. Steam is commonly used in Chinese feed mills to achieve the right conditions.
2. **Pelletizing**: Two common methods are ring die and flat die granulation. In ring die, material is pressed through holes in a rotating die and cut into pellets. In flat die, the material is evenly distributed and pressed out by a rotating press.
3. **Cooling**: After pelleting, the feed is hot and moist, so it must be cooled to reduce moisture content and prevent spoilage.
4. **Crushing**: Some feed is crushed after pelleting to meet specific size requirements for livestock and poultry.
5. **Sifting**: Finally, the feed is sifted to separate fine particles and ensure uniform pellet size, enhancing overall product quality.
