The working principle of the feed pellet machine;
The working principle of the feed pellet machine mainly includes the following steps:
1. Feeding: The mixed and crushed feed raw materials are fed into the pellet mill.
2. Pressing: The raw materials are pressed into uniform particles in the granulator, and the mold orifice plate is cut.
3. Forming: Add an appropriate amount of water to promote the formation of pellets, and adjust the parameters of the pellet machine to adapt to different feed ingredients and requirements.
The resulting pellet feed density increases and is easy to transport and store, providing high-quality feed for the animals.

Debugging process
First of all, it is necessary to understand and master the performance and operation process of the pellet feeder.
Before commissioning, the operation of specific equipment should be checked one by one, to understand the crushing particle size of the pulverizer that matches the die hole of the granulator used, the particle size of the raw material should be fine, but not too fine, preferably coarse, medium and fine, and the ideal particle size distribution is recommended as follows: A. The particle size is more than 3.35mm≤1%, B, the particle size is more than 2.0mm≤5%, C, the particle size is more than 1.0mm≥<> about 20%, D, the particle size is more than 0.5mm, about 30%, E, The particle size below 0.25mm shall not be less than 20%, and the particle size F and the particle size above 0.25mm shall be about 24%.
Before commissioning, the warehouse should be cleaned to remove sundries such as stones and welding slag left during the installation process;
Before commissioning, check whether the steam pipeline system used has good pressure reduction function and drainage function to ensure that the quenching and tempering steam required for granulation is dry and saturated, and ensure that there is always 0.058-0.4MPa steam behind the pressure reducing valve;
Before starting the granulator, the distance between the pressure roller and the ring die should be adjusted, generally when the ring die rotates, the pressure roller does not seem to rotate (that is, the distance between the pressure roller and the ring die is 0.1~0.4MM), the distance between the ring die and the pressure roll can not be adjusted too small, resulting in direct friction, which will not only accelerate the wear of the ring die and the pressure roller, but also reduce the unit output in the production process.
When starting the granulation equipment, the feed amount should not reach the maximum value instantaneously, before the feed amount reaches the ideal value (that is, the motor current value is 85~95% of the rated current value during normal production), a little steam should be added at the same time, and a little steam should be added at the same time.
Prevention and corrective measures for undesirable phenomena
The particles have axial crack or radial crack phenomenon, high crushing rate and low yield, the reason for this phenomenon is that the quenching temperature cannot be reached, and the material maturity is poor, so the quenching and tempering temperature should be increased to increase the amount of steam during quenching and tempering; It could also be that the tool is far away and blunt, making the particles shortened or torn instead of being cut off;
The length of the particles is different, and the distance of the cutting knife should be adjusted or the deflection and scraping position of the material should be adjusted;
The surface of the particles is smooth, but the hardness is too high, which may be due to the large compression ratio of the ring die, and the compression ratio of the ring die should be reduced;
The surface of the particles is not very smooth and the crushing rate is high, which may be due to the small compression ratio of the ring die, and the compression hole should be expanded. Ring die pressing;
When the particle water content is high, the output is low, and the machine is often blocked, it may be that the pressure reducing valve can not play the role of pressure reduction or the trap can not play the role of hydrophobicity, the pressure reducing valve should be adjusted so that the steam pressure entering the regulator reaches 0.1-0.4MPa, and the trap can play the role of hydrophobic. The quenching and tempering temperature can also be increased accordingly, because the increase in temperature is conducive to the improvement of the maturity of the material, and the moisture content of the material increases by about 1% for every 11 °C increase in the general temperature;
The tension of the two motor belts should be adjusted so that the tension is as consistent as possible.
Processing technology of feed pellets
Feed granulation: The raw materials are pressed into pellets of different diameters by the feed pellet machine, which can improve the palatability of the feed and reduce dust.
Granulation: After crushing and mixing, different raw materials are pressed into granules by mechanical conditioning machine and granulator. The specific particle size depends on the size of the ring die of the pellet mill.
Pellet quality control: Pelletization is a complex process that requires adequate conditioning, cooling and storage to control pellet quality, avoid mildew and ensure feed safety.
Process flow: Different products and habits can have different process combinations, generally speaking, the cleaning and decontamination section is located in the front, and the granulation section is located in the rear. In addition, there are two different combinations of crushing, batching and mixing sections.
The above is the processing process and related precautions of feed pellet machine.
What is the maximum compression ratio of the feed ring mold:
What is the maximum compression ratio of the feed ring die? or what is the correct compression ratio of the ring die? In fact, there is no fixed standard for the compression ratio of the pressure roller ring die, because the compression ratio of the ring die needs to be related to the die hole, diameter, production variety, etc. It is recommended to start with raw materials, fish feed can be used 12-11:1, pig and poultry pellet feed can be used 10:1 compression ratio. In addition, the compression ratio of high-grain compound feed is recommended to be between 8-12.5, the compression ratio of heat-sensitive feed and urea feed is recommended to be between 5-8, the compression ratio of concentrated feed with high natural protein content is recommended to be between 5-11, and the compression ratio of dairy cow compound feed is recommended to be between 7~15. Considering the pore size of the ring die, some feed manufacturers have specially analyzed it as a record: the recommended ring die pore size is 3.0 for mouse feed, and the compression ratio is about 1:12, and the recommended ring die pore size for chicken feed is 3.0, and the compression ratio is about 1:10-1:13. Other reference values: The compression ratio of the ring die with a bore diameter of 3mm is about 12-12.5, while the ring die with a bore diameter of 3.5mm is 13 and the bore diameter of 4mm is 14. Of course, according to the production formula of varieties with higher fiber content, the compression ratio of the ring die should be relatively small, and the compression ratio of the roughage ring die is recommended to be about 8:1. Livestock and poultry breeds, growth stages and pressing raw materials are different, select the best ring die compression ratio, and ensure that the effective length of the die hole is lifted downward, increase the thickness of the ring die, and open the pressure reducing hole.

Horizontal ring die granulator structure diagram:
The horizontal ring die granulator is to put the mold vertically, from top to bottom, and then turn 90 degrees into the pelletizing mold. The feed is a self-sliding feed, which is suitable for materials with heavy gravity and good fluidity. Rated capacity: 2-3 tons/hour, applicable hole diameter: 6-12mm, machine size: 3348*2390*2485mm, motor power: 160kW (220 horsepower). The horizontal granulator has reasonable structure, large weight, large floor area, high price, long life, which is 3 times that of the vertical granulator, high efficiency, high output per hour, low maintenance cost, and low frequency of replacement of wearing parts.
Key points of daily maintenance of horizontal ring die granulator
Frequently remove residual material from the cavity of the ring die
Before each production, the oil injection marks on the eccentric shafts of the two pressure rollers are filled with lubricating oil
Always check whether the gap between the pressure roller and the inner wall of the ring die is in a normal state
Check the tightness of the triangle tape and adjust it in time
When the main machine of the horizontal ring die pellet machine suddenly stops, it is recommended to check the fuse, remove the material in the ring die cavity, and reduce the feed amount accordingly.
These factors have an impact on the pellet hardness of compound feed:
Crushing process: the finer the particle size of the raw material crushing, the easier it is for the starch to gelatinize during the quenching and tempering process, and the less easy it is for the particles to be broken, so the hardness is greater.
Extrusion and puffing process of raw materials: After puffing, the degree of gelatinization of starch is larger, so the hardness of granular particles is also larger.
Mixing, adding water and oil injection process of raw materials: mixing and adding water is conducive to improving the stability and hardness of pellets in pellet feed.
Steam quenching and tempering process: steam quality and quenching and tempering time directly affect the quenching and tempering effect, the longer the quenching and tempering time, the greater the particle hardness.
Granulation mold: Technical parameters such as pore size and compression ratio of the ring die of the granulator will significantly affect the hardness of the granules.
Post-curing and post-spraying processes: Post-curing and post-spraying processes can improve the hardness of the particles.
Drying and cooling process: The cooling time and method of the pellets, as well as the drying and cooling treatment processes, will all have an impact on the hardness of the pellets.
The above are several factors that affect the hardness of compound feed pellets. As research continues to deepen, more influencing factors may be discovered in the future.
The following are the general requirements for some common feed pellet parameter indicators:
Ash content: generally less than 1%-3%.
Moisture content: generally less than 10%-12%.
Calorific value: generally required to be greater than 4000-4500kcal/kg.
Density: generally required to be greater than 600-700 kg/cubic meter.
Compressive strength: generally required to be greater than 98-100Mpa.
Particle size: generally required between 6-10 mm.
