What factors are affected by the production of pellet machine?
The granulating machine is used to develop a wet powder into the desired granules, and it is also possible to pulverize the dry granules to the desired granules. In our production and life, the application is more and more extensive. For the user to encounter the decrease of the output of the pellet machine in the production process, there are many factors affecting the production and production of the pelletizer. Here is a brief introduction to the production of the pelletizer. The main factor.
First, the material factor
1. Material volume quality
In general, the larger the volumetric 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 materials should also be considered.
2. Material moisture
The moisture content of the material is too high, which reduces the amount of steam added during granulation and affects the granulation temperature, thereby affecting the yield and quality of the granules.
3. Material granularity
It has fine particle size, large specific surface area and fast vapor absorption, which is beneficial to water regulation and high granulation yield. However, if the particle size is too fine, the particles are brittle and affect the quality of the particles; and if the particle size is too large, the wear of the stamper and the press roll is increased, the energy consumption is increased, and the yield is lowered.
Second, the material components
The material has high protein content. After heating, the material has high plasticity, increased viscosity and high granulation yield.
The addition of a small amount of grease helps to reduce the wear of machine parts and allows the particles to pass through the die holes, increasing the granulation yield.
3. Crude fiber
Appropriate crude fiber content is beneficial to the bonding of the granules, reducing the pulverization rate of the granules and increasing the granulation yield.
The cereal starch content is high, and it is easy to granulate under high temperature and high moisture, and the yield is also high.
Third, the operating factors
After the materials have been tempered, they should be held in groups and loosened. The material is easy to slip between the inner wall of the ring mold and the pressure roller, and even the pellets are not pressed, thereby reducing the granulation yield.
2. Coefficient of friction between material and roll and die
When the material and the pressure roller and the inner surface of the ring mold have a small coefficient of friction, the material is easy to slip, thereby reducing the yield. When the friction coefficient between the material and the inner wall of the die hole is too large, the material will not be pressed out of the die hole, and the granulation yield is reduced.
The pellet feed is not sufficiently cooled, the particles are loose, and the powder is increased after being lifted by the hoist. The powder is sieved and refluxed to reduce the granulation yield.
