How does poultry feed production machine affect pellets size?

Author : Horne Ottesen | Published On : 24 Feb 2026

With the strenuous development of modern-day tank farming and feed sector, the demands for feed quality are getting higher and greater. For pellet feed created by poultry feed production machine, pellet size is an extremely vital quality examination index.

Cool and also consistent pellet feed not only satisfies the sales demands of feed makers, however additionally satisfies the actual breeding requirements of users. Pellets that are too long, as well short or unequal are not conducive to pet feeding. In actual manufacturing, the size of the pellets created by the poultry feed production machine is generally called for to be 2 to 3 times the size of the pellets.

For example, granules with a size of 3 mm are normally generated with a length of 6 to 9 mm. Certainly, according to real individual needs and various feed ranges, the length demands are not always within this range.

For that reason, in order to generate feed pellets that fulfill the demands or as close as feasible to the requirements, we will certainly talk about some aspects that affect the pellet length of the poultry feed pellet making machine and also discover the equivalent control approaches to make it beneficial to the manufacturing requires, which is necessary for feed makers importance. Based upon years of experience in poultry feed granulator layout as well as field debugging, we will certainly review this issue from the following aspects.

1. Criteria influencing the poultry feed production machine itself:

The output of the poultry feed production machine is Q (kg/h), the internal diameter of the ring die is D (mm), the efficient size of the ring die is W (mm), the straight rate of the ring die is V (m/s), as well as the rotational speed of the ring die is n (r/ minutes), the ring die aperture is d (mm), the ring die opening up rate is m, the variety of openings is n (items), and the granulation size is L (mm),.

For the above formula, it is simple to evaluate the variables influencing the pellet size L of the poultry feed production machine:.

( 1) The impact of the result of the poultry feed manufacturing machine.

It can be seen from the formula that the pellet length L is symmetrical to the output Q. With other criteria continuous, the greater the return, the longer the pellet, otherwise the shorter the pellet. Therefore, readjusting the outcome of the poultry feed pelletizer to satisfy specific pellet size demands is a feasible alternative. In actual feed production, feed manufacturers do the very same, sometimes giving up large quantities of output to fulfill pellet length demands. This issue will be mentioned in the complying with conversation.

( 2) Influence of ring die line speed or rotational speed.

It can be seen from the formula that the pellet size L is inversely proportional to the ring die direct rate V or the ring die linear velocity n. When the feeding rate, that is, the output Q, remains consistent, the quicker the ring die rate, the much shorter the immediately extruded pellets, and the other way around. For different sizes of poultry feed pelletizers, the rotational rate of the ring die differs significantly.

Normally, the revolving rate of the small poultry feed making machine is high, as well as the revolving rate of the large poultry feed manufacturing machine is low, but the direct speed of the ring die is regulated within an ideal array, normally between 6m/s ~ 9m/s, to fulfill the needs of granulation.


When Richi Pellet Machine of the ring die is small, the high quality of the pellets is high, yet the pellets may be longer than needed, and also the line rate is as well little, which will certainly influence the outcome; when the direct speed of the ring die is high, although it is beneficial to improve the output, the pellets may be much shorter than the needs, and also the top quality of the pellets It will certainly become worse, which needs the feed producer to choose its very own ring die line rate according to various feed selections, and realize it by changing the transmission ratio of the poultry feed production machine transmission system.

( 3) Impact of ring die aperture as well as porosity.

The ring die aperture D has no straight impact on the pellet size L, it has an effect on the length L together with the number of openings N, that is, the size of the ring die opening up proportion, because the opening ratio and also the square of the ring die diameter D as well as the variety of openings N is proportional to the product of. The larger the porosity of the ring die, the much shorter the pellets, and also vice versa, the longer the pellets. The aperture proportion of the ring die represents different ring die apertures. As an example, a ring die has an opening rate of concerning 25%, and a ring die has an opening rate of concerning 38%.

Usually talking, the larger the pore size, the higher the open porosity. In actual manufacturing, particularly when creating small-diameter pellets, such as 1.8 mm shrimp, some users complain that the pellets are as well long, which is triggered by the fairly reduced opening price of the ring die when the aperture is tiny. One of the services is to sacrifice part of the return, or to attain by enhancing the line rate of the ring die. Furthermore, adjusting the cutter is reviewed below.

( 4) Influence of ring die inner size, reliable width and pellet thickness.

For the poultry feed production machine, the internal size D of the ring die and the effective size W of the ring die are dealt with parameters, which usually do not alter, as well as it is challenging for customers to change them, so they will certainly not be discussed right here. The pellet thickness is associated with the raw product for granulation as well as likewise to the compression ratio of the ring die.

The higher the compression proportion, the firmer and denser the pellets will be. However, for general items, the pellet thickness is not very various, so the pellet thickness is not the main affecting specification, so it will certainly not be discussed way too much here. In short, for the exact same granulation basic material, the larger the pellet thickness, the much shorter the pellet length.

2. How to address the oil-free phenomenon in the production process of the poultry feed pellet making machine?

Poultry feed manufacturing machines are powered by electricity, but in many cases oil drive has ended up being vital. As all of us know, the equipment works quickly and depends totally on the power belt, and oil is specifically essential as the power supply of the devices.

Address the issue of no oil in the poultry feed manufacturing machine:.

( 1) The supplier of the full set of tools with a result of 5 lots of concentrate suggests that you inspect the primary shaft and also rotor of the poultry feed pellet machine initially to make sure that there is no product deposit in the void.

( 2) The supplier of the small poultry feed production machine recommends that the customer needs to thoroughly clean up the filter screen in the oil filter.

( 3) Get rid of the oil block of the poultry feed production machine. Usually, the device of selection is: a reliable hollow tube of a certain length, generally used to cleanse the pollutants packed right into the oil hole.


( 4) We usually say that along with examining the above matters, we need to additionally inspect whether there is oil leak at the refueling part. If the oil leakage is especially severe, it will most definitely cause no oil supply. The service to this issue is to add an oil liner.
