The granulation mechanism has fast particle size and good effect. The special filter screen is designed and carefully sieved. The friction filter rod can crush the sieved solid particles and is widely used in the pharmaceutical, chemical and food industries. This machine can replace the swinging pellet machine and is a new generation of pellet equipment. In the production of granulating machine pellets, there are sometimes particulate materials with abnormal appearance. For less experienced or new feed manufacturers, sometimes the problem is not found. In the following, the reasons and improvement methods of the seven common abnormally-produced granular materials are introduced to everyone for comparison and reference in feed production.
1. The pellets are bent and show many cracks on one side.
This phenomenon is usually produced when the pellets leave the ring mold. In production, when the position of the cutter is adjusted far from the surface of the ring mold and the edge is blunt, the particles are broken or torn by the cutter instead of being cut when being extruded from the die hole. There are many cracks on one side and the other side. Such pellets tend to break from these cracks as they enter the cooler for cooling or transportation, resulting in excess pellets produced.
Improvement method:
a) increase the compression force of the ring mold on the feed, that is, increase the compression ratio of the ring mold, thereby increasing the density and hardness value of the ;
b) crush the feed ingredients to a finer size. If molasses or fat is added, the uniformity of molasses or fat should be improved and the amount added should be controlled to increase the compactness of the pellets and prevent the feed from becoming soft.
c) adjust the distance of the cutter from the surface of the ring mold. Usually, the distance from the outer edge of the cutter to the outer surface of the ring mold is not greater than the diameter of the feed pellets produced, or the sharper cutting Blade can be replaced. For small diameter pellets, it can also be used. Thin blade and make the thin blade close to the surface of the ring mold;
d) The use of a bonding granulation aid helps to improve the bonding force inside the particles.
