The granulator is used to develop the wet powder into the desired particles, and also to crush the dry material into the desired particles. The application in our production and life is more and more extensive. For users who encounter a decrease in the output of the particle machine during the production process, there are actually many factors that affect the production output of the particle machine. The following is a brief introduction to the impact of the particle machine. The main factors of production.
1. material factors
1. Material volume mass
Generally speaking, the greater the volume and mass of the material, the higher the granulation yield. When selecting raw materials, in addition to considering the nutritional needs, the bulk density of the material should also be considered.
2. Material moisture
If the moisture content of the material is too high, the amount of steam added during granulation will be reduced, which will affect the increase of the granulation temperature, thereby affecting the yield and quality of the granules.
3. Material granularity
Fine particle size, large specific surface area, fast steam absorption, conducive to moisture adjustment, high granulation yield. However, the particle size is too fine, the particles are brittle, affecting the quality of the particles; and the particle size is too large, it will increase the wear of the pressure mold and the pressure roller, increase the energy consumption, and reduce the output.
2. material components
1. Protein
The protein content of the material is high, the plasticity of the material after heating is large, the viscosity is increased, and the granulation yield is high.
2. Grease
Adding a small amount of grease is beneficial to reduce the wear of machine parts, and make the particles easily pass through the die hole, and increase the granulation output.
3. Crude fiber
Appropriate crude fiber content is conducive to the bonding of granules, reducing the pulverization rate of granules and increasing the granulation yield.
4. Starch
Cereal starch content is high, easy to granulate under high temperature and high moisture, and the yield is also high.
3. operational factors
1. Water conditioning
After quenching and tempering, it is advisable to hold the material into a ball and disperse it after release. The material is easy to slip between the inner wall of the ring die and the pressure roller, and even the pellets cannot be pressed, thus reducing the pelletizing output.
2. The friction coefficient between the material and the roller and the mold
When the friction coefficient between the material and the inner surface of the pressure roller and the ring mold is small, the material is easy to slip, thus reducing the output. When the friction coefficient between the material and the inner wall of the die hole is too large, it will cause the material to be out of the die hole and reduce the granulation output.
3. Cooling
Pellet feed cooling is not sufficient, the particles are loose, and the powder increases after being lifted by the hoist. The powder is screened and then refluxed for granulation, thereby reducing the granulation yield.
