How to solve the problem of different particle sizes produced by the feed pellet machine
Feed pellets of varying lengths affect the overall appearance of the feed, and can also result in insufficient feed utilization by the animal, resulting in a waste of feed pellets produced by different particle sizes .
Uneven distribution of materials in the granulation chamber at the same time;
2 The feeding amount of the granulator is not uniform, and the quenching and tempering effect fluctuates greatly;
3 die roll gap is inconsistent;
4 pressure roller wear is inconsistent;
5 The wear amount of the ring guide port is inconsistent along the axial direction or there are more holes blocked on the ring die;
6 along the axial direction of the ring mold, the discharge speed at both ends is less than the intermediate speed.
7 When designing the ring die, the pressure reduction hole is too large compared with the effective hole, and some particles are broken in the pressure reduction hole; the ring die of small particle size is particularly prone to unevenness of the particle length due to the length of the pressure reduction hole.
8 The position or angle of the cutter is not reasonable.
The particle size produced by the feed pellet machine is not improved.
1 Adjust the length, width or angle of the fabric scraper.
2 When the production is just started and the production is finished, the feeding amount is small and uneven, which leads to the short length of the particles, and if it is required to be high, it must be taken out. In the production process, the feed volume and steam quenching should be kept stable. The number of cutters to be input should be matched with the output. If necessary, the yield should be sacrificed to obtain a suitable pellet length.
3 Adjust the pressure roller adjustment screw to make the gap of each die roll consistent.
4 The new ring mold should be equipped with a new pressure roller. The wear amount of each pressure roller in use should be consistent; if the axial wear of the pressure roller and the ring mold is inconsistent, the high place should be polished if necessary.
5 Repair the guide port of the ring die; clean it in time, and block the hole on the ring die.
6 When designing the ring die, along the axial direction of the ring die, the compression ratio of the three rows of holes at both ends can be 1 to 2 mm smaller than the middle (depending on the formulation and particle size).
