Some agricultural crops are often screened in agricultural production, which is the use of the trommel screen. The trommel screen is a good substitute for the traditional manual screening method, which has higher screening efficiency and promotes the progress of agricultural screening operations.
Application in feed processing:
The application of screening technology in feed processing focuses on the cleaning of impurities in raw materials and the classification of raw materials or products according to particle size, including raw material impurity cleaning, pulverizing material grading, powder impurity cleaning before granulation, and granulation products.
Factors affecting screening efficiency during feed processing:
The passage of particles has certain contingency and can only be studied by statistical means. Generally, for cylindrical particles, the rectangular mesh has better pass performance; and for irregular particles with small difference in size in each direction, the pass performance of the circular hole is better. The particle size, water content, friction characteristics, fluidity, etc. of the material are all related to the screening process. The thickness of a suitable layer should be determined by experiment. When the screen angle is small and the amplitude of the screen is large, the layer can be slightly thicker.
The retention ratio on the sieve of the sieve material should be retained and the retention ratio on the sieve that should pass through the sieve material. These two indicators affect the removal effect of impurities and the loss of net raw materials in the cleaning operation, affect the particle size and output of the product in the classification operation, and affect the feasibility of the classification result in the detection.
It can be seen that the performance of trommel screen in agriculture is mainly concentrated in the feed processing industry, and the sieved feed application has a better feeding effect in the animal husbandry. The application of this equipment is gradually spreading widely, and it is believed that the future will have a greater impetus to agriculture.
