The influence of raw materials on the hardness of granule of control granulator

In the pelletizing machine, the various aspects of raw materials will affect the hardness of the particles, including the formula and treatment process of raw materials will make the hardness of the particles change, so when using the pelletizing machine, we need to improve according to needs. Today, let's talk about how raw materials affect the particle hardness of the granulator.

In the grinding process, the crushing size of the raw material is a decisive factor in the hardness of the particle. In general, the finer the particle size of the raw material, the easier the starch is to gelatinize during the granulator conditioning process, the stronger the adhesion in the granular material, the less easy to break, and the greater the hardness. The particle size of the crushing is between 900μm and 300μm, and the particle size of the secondary crushing is between 600μm and 300μm. The particle size distribution of the crushing is conducive to the granulation and appearance quality of the particles, and can ensure the appropriate hardness and low crushing rate of the product.

Through the pretreatment of raw materials, anti-nutritional factors in raw materials can be destroyed, bacteria can be killed, harmful substances can be eliminated, raw materials can be denatured and starch can be fully gelatinized. Gelatinized starch has a significant effect on particle hardness. Because the gelatinization degree of the particle material is large, the hardness of the particle is also large, and the hardness of the particle must be reduced by other methods.

The mixing of raw materials can improve the uniformity of various particle size components, help to maintain the consistency of particle hardness and improve product quality. The water mixing process is a very mature process in some companies. In the production of pellet feed, adding 1% to 4% water in the blender can improve the stability and hardness of pellet feed. But adding water to the blender in a granulator is very dangerous. It is necessary to adjust according to the influencing factors such as raw material moisture and weather changes, ensure that the finished product moisture is within the safe range, and clean the mixer at the end of every day, otherwise there may be mold and oxidation of the finished product.
