Effect of feed grinding granularity on feed quality

The size of the crushed particle size should be determined according to the types of raw materials, the types of animals to be fed, the growth stage and the process requirements. Too coarse and too fine particle sizes have disadvantages and cannot achieve the best production state. Next, Liangyou shares will summarize the impact of crushing particle size on feed quality from the following aspects.

1. The impact of crushing particle size on feed utilization rate

The crushing of the materials improves the palatability of livestock and poultry, and reduces the prolonged collection time caused by chewing when the animal eats, affects the animal's rest, digestion and absorption, increases the energy consumption of feeding, and reduces the utilization rate of feed. Of course, it is not that the finer the material is pulverized, the better. Generally, the pulverized particle size of the material is preferably 0.5-2.0mm, which may vary due to different types of livestock and poultry, feeding stages and raw materials. Because the powder is too fine, the palatability of livestock and poultry will become poor, and the material will stick to the mouth of livestock and poultry and be difficult to swallow. At the same time, too fine powder can easily cause gastric ulcers in livestock and poultry. Moreover, because the crushing is too fine, it will increase the power consumption of feed processing, reduce the output, increase the wear of the crusher and its hammers, screens and other accessories, and reduce their service life.

2. The influence of crushing particle size on the uniformity of feed mixing

The size of the crushed material affects the uniformity of the feed. The smaller the average particle size of the mixed material, the more uniform the particle size, the slower the mixing speed, and the higher the mixing uniformity that can be achieved by mixing, and the less prone to classification phenomenon during subsequent transportation and storage. On the contrary, when several materials with a larger difference in particle size are mixed, the uniformity that can be achieved by the mixing is poor. Therefore, in terms of mixing technology, the crushed particle sizes of various feed materials are required to be small and similar in order to achieve a good mixing effect and ensure product quality.

Third, the impact of crushing particle size on granulation

The crushing particle size of the material has a greater impact on the granulation process and particle quality. The particle size and particle size composition of the same material are different, and the quality of the produced particles will be different. The finer the grain material, the more the starch particles will undergo. After steam preparation, gelatinization can be obtained more fully, and the water content is more uniform. At the same time, fine materials can reduce the wear of the ring die, and can produce smoother and crack-free particles. The particle structure is compact and the pulverization rate is low. However, too fine pulverization will increase the power consumption of pulverization, reduce the output of the pulverizer, and make the As the temperature of the material rises, this kind of material is prone to arching in the warehouse.

If the feed size is too fine or too coarse, it is not good. You should make judgments and adjustments based on your actual situation. Liangyou will share more professional information and provide various old feed factory renovation services. Welcome attention and consultation.
