The impact of the particle size of the feed crusher on its quality
Feed crusher are widely used in the current feed processing industry due to their simple structure and strong adaptability. An important part of the feed processing process to improve feed quality is the crushing process, which can make the feed fully and reasonably utilized.
The Impact of Feed Crushing Granularity on Feed Quality
The feed crusher is widely used in the feed processing industry due to its simple structure and strong adaptability. In the feed processing process, the quality of the crushing process directly affects the overall quality of the feed, and the control of the crushing granularity is particularly important. Crushing granularity not only affects the feed utilization rate but also has a profound impact on mixing uniformity, pellet quality, and other aspects. This article analyzes the specific impact of feed crushing granularity on feed quality from three main aspects.
The Impact of Crushing Granularity on Feed Utilization Rate
The crushing granularity plays a crucial role in the feed utilization rate. For grain-based raw materials such as corn, wheat, and soybeans, their outer shells are hard and not easily digestible. Feeding them directly to animals may prevent the nutrients from being fully released, thus affecting digestion and absorption. Through the crushing process, the tough outer shells are broken, exposing the internal nutrients, which increases the contact surface area of the feed, allowing the digestive juices of animals to better penetrate and digest the feed, thereby improving its digestibility.
If the crushing granularity is finer, the surface of the particles becomes more porous, significantly increasing the contact area between the digestive fluids and the feed. This improves the feed utilization rate. For livestock and poultry, the digestion and absorption of feed largely depend on the particle size and uniformity of the crushing process. Therefore, appropriately adjusting the crushing granularity can not only improve the nutritional value of the feed but also significantly enhance the animals’ performance.
The Impact of Crushing Granularity on Mixing Uniformity
The crushing granularity directly affects the uniformity of the feed mixture. Experiments show that when the average particle size of the mixed material is smaller and the particle size is more uniform, the mixing effect is better. The higher the mixing uniformity, the less likely it is for segregation to occur during transportation and storage. Therefore, to achieve a good mixing effect and produce high-quality feed, it is essential to ensure that the particle size of various raw materials is small and uniform.
If the crushing granularity is larger, the size difference between the particles may be more pronounced, which affects the mixing effect and may even lead to layering. In feed production, to ensure uniform mixing, it is usually necessary to control the crushing granularity of different raw materials within a small and similar range. This approach can effectively improve the mixing effect and ensure feed uniformity. It also helps avoid waste of raw materials and uneven distribution of nutrients.
The Impact of Crushing Granularity on Pelletizing Process and Pellet Quality
The crushing granularity also has a significant impact on the pelletizing process and the final quality of the feed pellets. For the same material, if the particle size and granularity composition differ, the quality of the produced pellets will also vary. When the grain feed is crushed more finely, the starch particles undergo better gelatinization during steam conditioning. This leads to more even moisture distribution. This can also reduce wear on the ring die. As a result, it leads to a more compact pellet structure and significantly reduces the rate of powder generation.
In addition, finer crushing granularity helps in forming more uniform and dense pellet structures during the pelletizing process. This not only ensures the strength and stability of the pellets. It also effectively reduces the powdering rate and material loss. However, excessive fine crushing may lead to increased power consumption, reduced production output, and potential material arching issues. Therefore, in actual production, it is necessary to balance production efficiency with energy consumption while ensuring an appropriate crushing granularity.
Conclusion
In conclusion, feed crushing granularity plays an important role in the feed processing process. It not only affects the feed utilization rate but also directly impacts mixing uniformity and pellet quality. In actual production, it is necessary to reasonably control the crushing granularity according to different feed raw materials, processing requirements, and equipment conditions to achieve the best processing effect and feed quality. Proper crushing granularity can improve feed nutrient absorption, optimize mixing effect, and improve pellet quality. This ensures that livestock and poultry can fully absorb the nutrients in the feed. As a result, it promotes their growth and development, and enhances the economic benefits of the feed.
