Influence Factors Of The Pellet Making Machine Production Efficiency

As a professional animal feed machinery manufacturer, our product structure and price are reasonable. This article will introduce the influence factors of the pellet making machine production efficiency in detail.

Influence Factors Of The Pellet Making Machine Production Efficiency

Feed machinery’s mainframe consists of feeding, mixing, pelletization, transmission, and lubrication systems. Due to the process arrangement and operation technology of the feed pellet machine, many feed mills have failed to meet the expected design requirements. And the surface of the pellet is not smooth, the hardness is low, easy to break, high powder rate and so on. The main reasons that affect the production efficiency of the feed pellet mill during the pelletization process are as follows:


1. Raw material factor. The raw material factors directly affect the effect of pelletization. The materials with higher starch content are easily gelatinized by steam. After quenching and tempering, these raw materials have certain viscosity, which is beneficial to the formation of granules. For raw materials with high crude fiber content, a certain amount of oil added, and the friction between the material and the die can reduce during pelletization. This is beneficial to the material passing through the die, and the appearance of the pellets is smooth after forming. Generally, the added amount is about 1%. The added amount is too high, which is easy to cause the pellets to lose. If more fat needed, it can consider to spray after pelletization and is particularly suitable for producing high-energy feed. The pellet size of the pulverized material determines the surface area of the feed composition. The finer the particle size, the larger the surface area, and the materials faster absorbed the moisture in the steam. Which is beneficial to the quenching and tempering of the material.

2. Material Flow Control. In order to make the feed pellet mill work at full load without interruption, the material flow entering the pellet making machine must meet the pelletization needs. And the feed structure should effectively eliminate the intermittent phenomenon of the feed due to agglomeration. Many feed mills are busy looking for the cause of the feed pellet mill when the machine production efficiency is not normal and neglect the incoming factors. In fact, many times the unstable flow of the incoming material caused the production efficiency.

3. Production operations. Correctly control the gap between the pressure roller and the die. The roll gap is too small, the stamper and the press roll easily worn, and the noise is large. If the gap is too large, it will affect the material extrusion. After the various parts of the pellet making machine adjusted, the mechanism can open. First open the feed pellet machine, conditioner, feeder, at this time the feeder should in a small feeding state. In order to prevent the internal debris from entering the die, the external discharge door on the operation door should open, and the waste material in the cleaning machine should mix. After the impurities are clean, the material can introduce into the stamper. To be cautious, the hand should hold the handle of the discharge door outside the machine, first let some of the material enter the die, and then observe whether there are pellets out of the mold, and pay attention to the current change. If the pellets can produce normally, the current is relatively stable, the fluctuation range is not large, and the rated current not reached, then the material flow rate can increase and the amount of steam can increase at the same time.


4. Die mold. Whether the material can squeeze through the die during the granulation process depends on the amount of pressure and friction, that can generate in the die hole. This is related to the coefficient of friction between the material, the wall of the die, the moisture content, the pellet size of the material, the temperature, the buffering time of the plastically deformable part of the material, and the compressibility of the material. These characteristics closely related to the hole depth and the pore diameter of the die. Generally speaking, the compression ratio of the die mold is small, the effective length of the die hole is short.

The material formed the pressure in the die hole is small, and the ring die easily extruded. Therefore, the yield is high, but the produced pellet is...
