For different granulation requirements, we need to analyze the actual situation flexibly. It is necessary to select the correct ring mold parameters and operating conditions of the straw granule machine according to the material preparation characteristics and the specific characteristics of each feed manufacturer. In order to produce high quality feed. Let's take a look at the specific content below.
During production, if improperly handled, it may cause the straw granule ring to rupture. According to the experience analysis, the main reasons for such a situation are: 1. The ring of the transmission wheel is worn to cause cracking of the ring mold; 2. The ring of the die is worn or deformed to cause cracking of the ring die; 3. The wear of the transmission key causes the ring die to collide. Cracking; 4, the effect of the iron removal device is deteriorated, so that the ring mold working surface has metal object indentation, which causes the ring mold to crack; 5, the gap between the ring mold and the pressure roller is too small, thus causing the ring mold to crack.
In addition, in the production and processing, there are other situations. For example, after inspection of the finished product, it was found that the feed pellets were curved and many cracks appeared on the outer side. The main reasons for this are: 1. The cutter is too far away from the ring mold, and it is relatively blunt; 2. The powder is too thick; 3. The feed hardness is too low.
Therefore, in this case, we need to move the cutter properly, or replace the cutter. In addition, during the straw particle mechanism, increase the fineness of the pulverization, increase the effective length of the die hole, and add molasses or grease if necessary. . Another situation is the problem of horizontal transverse cracks on the surface of the particles. This is mainly due to the fiber being too long, the quenching time is too short and the humidity is too large.
Therefore, in view of this situation, we need to reasonably control the fineness of the fiber, and according to the operating state of the straw pellet machine, appropriately prolong the quenching and tempering time, and control the temperature of the raw material to reduce the moisture. In this way, the problem of transverse cracks can be effectively reduced, and the particle level of the straw granules is improved.
