Feed pellets need to go through a series of processes from raw materials to pellets, which involve many sections, and many sections require a lot of feed machinery. For example, the mixing section requires the addition of a mixer, and the granulator in our granulation section plays an important role. Next, we will analyze it in order.
1. Finished product inspection screen-cleaning of powder before granulation;
2. To be granulated bin + buffer bucket;
3. Feeder (single and double screw, full and half pitch, frequency conversion speed regulation);
4. Conditioner (low speed 125 rpm/min, high speed 125-500 rpm) (also used for variable frequency speed regulation); single-shaft blades, double-shaft blades (DDC), (jacket insulation type, thermal armor type) )
5. Granulator;
Ring die (compression ratio 1:5-22)
The quality of the ring die largely determines the pellet quality and pelletizing cost
6. Cooler: The temperature of the pellets leaving the pelletizer is generally above 80℃, and the moisture
The content is 14-18%, in order to facilitate storage, it must be cooled and dried. Generally, it needs to be cooled to
Not higher than room temperature 5℃. (Depends on effective cooling time and air volume, etc.)
7. Crusher: used in the production of crushed particles, generally used for fry and fry feed;
8. Grading sieve: sieve out the powder and large impurities in the cooled product
(According to the particle size, the screen size is reasonably equipped, and the three-layer screen is preferably equipped when selecting the equipment. The output reserve is large and the screening effect is good!)
