Abstract
Description
Technical Field
[0001] This utility model relates to the field of pig feed production technology, specifically a crushing roller screen for preventing clumping of pig feed powder and oil. Background Technology
[0002] In the modern pig feed production process, in order to meet the nutritional needs of pigs at different growth stages, feed often needs to add ingredients such as oil to improve energy density and palatability. However, after powder and oil are mixed, oil clumps of different sizes are easily formed. These oil clumps not only destroy the uniformity of feed nutrients, but may also block feed delivery pipes, affect pelleting effect, and reduce production efficiency and product quality.
[0003] Currently, the commonly used anti-agglomeration methods in the industry are mainly mechanical stirring and vibrating screening. Mechanical stirring uses high-speed rotating stirring blades to impact and shear the material, but the dispersing effect is limited for highly viscous oil clumps, and prolonged stirring may lead to the loss of heat-sensitive nutrients in the feed. Vibrating screening uses screen vibration to separate agglomerated materials, but existing screens are inconvenient to install and disassemble, and cannot be easily cleaned, affecting the screening effect. Existing crushing devices use crushing rollers and crushing teeth to crush materials, but the distance between the crushing teeth and crushing rollers is fixed, which cannot adapt to materials with different degrees of agglomeration, affecting the uniformity of the feed, and it is impossible to control the amount of material entering the screening device after crushing, affecting the screening effect. Therefore, it is necessary to design a crushing roller screen for preventing agglomeration of oil clumps in pig feed powder to solve the above problems. Utility Model Content

[0040] In actual operation, when this device is used during feed production, and when it is necessary to crush and screen the oil clumps formed after mixing powder and oil, the oil clumps are first fed into the top of the crushing box 212, and the collection device is placed at the bottom of the feed pipe 225. The crushing roller 2192 and the crushing teeth 216 mesh with each other.
