With the vigorous advancement of modern-day tank farming as well as feed market, the needs for feed top quality are getting higher and also greater. For pellet feed generated by poultry feed production machine, pellet length is a very crucial high quality assessment index.

Neat as well as constant pellet feed not only fulfills the sales requirements of feed manufacturers, yet additionally meets the real reproducing needs of individuals. Pellets that are too long, too brief or unequal are not for animal feeding. In actual production, the length of the pellets created by the poultry feed production machine is generally required to be 2 to 3 times the diameter of the pellets.

As an example, granules with a diameter of 3 mm are generally generated with a length of 6 to 9 mm. Certainly, according to actual individual requirements and also various feed varieties, the size requirements are not necessarily within this range.

Consequently, in order to create feed pellets that meet the requirements or as close as possible to the needs, we will certainly talk about some factors that influence the pellet size of the poultry feed pellet making machine as well as discover the matching control methods to make it beneficial to the manufacturing needs, which is essential for feed producers importance. Based upon years of experience in poultry feed granulator layout and field debugging, we will review this issue from the adhering to elements.

1. Specifications influencing the poultry feed manufacturing machine itself:

The output of the poultry feed production machine is Q (kg/h), the inner size of the ring die is D (mm), the effective size of the ring die is W (mm), the linear rate of the ring die is V (m/s), and the rotational rate of the ring die is n (r/ minutes), the ring die aperture is d (mm), the ring die opening rate is m, the number of openings is n (items), and also the granulation length is L (mm),.

For the above formula, it is easy to assess the elements affecting the pellet length L of the poultry feed manufacturing machine:.

( 1) The influence of the result of the poultry feed production machine.

It can be seen from the formula that the pellet size L is symmetrical to the result Q. With other specifications constant, the higher the yield, the longer the pellet, otherwise the shorter the pellet. For that reason, adjusting the result of the poultry feed pelletizer to fulfill details pellet size demands is a possible alternative. In actual feed manufacturing, feed manufacturers do the exact same, often giving up big quantities of outcome to fulfill pellet size requirements. This concern will be pointed out in the adhering to conversation.

( 2) Impact of ring die line rate or rotational speed.

It can be seen from the formula that the pellet size L is vice versa symmetrical to the ring die straight speed V or the ring die linear speed n. When the feeding rate, that is, the result Q, continues to be consistent, the much faster the ring die speed, the shorter the instantaneously extruded pellets, and the other way around. For https://pelletmachinemanufacturer.com of poultry feed pelletizers, the rotational rate of the ring die differs greatly.

Normally, the revolving rate of the little poultry feed making machine is high, as well as the rotating rate of the large poultry feed production machine is reduced, however the linear speed of the ring die is controlled within an appropriate array, usually in between 6m/s ~ 9m/s, to meet the requirements of granulation.


When the direct rate of the ring die is small, the top quality of the pellets is high, yet the pellets may be longer than required, as well as the line rate is as well tiny, which will impact the outcome; when the straight speed of the ring die is high, although it is beneficial to improve the result, the pellets may be shorter than the requirements, and also the quality of the pellets It will certainly become worse, which calls for the feed producer to pick its very own ring die line speed according to different feed selections, and realize it by changing the transmission proportion of the poultry feed production machine transmission system.

( 3) Influence of ring die aperture and porosity.

The ring die aperture D has no direct effect on the pellet size L, it has an effect on the size L along with the number of openings N, that is, the size of the ring die opening up ratio, due to the fact that the opening ratio as well as the square of the ring die size D as well as the variety of openings N is symmetrical to the product of. The larger the porosity of the ring die, the much shorter the pellets, and also the other way around, the longer the pellets. The aperture ratio of the ring die represents various ring die apertures. For example, a ring die has an opening price of regarding 25%, and a ring die has an opening rate of concerning 38%.

Generally talking, the larger the pore dimension, the greater the open porosity. In actual manufacturing, particularly when generating small-diameter pellets, such as 1.8 mm shrimp, some individuals complain that the pellets are also long, which is caused by the relatively low opening rate of the ring die when the aperture is tiny. One of the options is to give up part of the return, or to achieve by raising the line speed of the ring die. Additionally, changing the cutter is discussed below.

( 4) Impact of ring die internal size, effective size and pellet thickness.

For the poultry feed manufacturing machine, the inner diameter D of the ring die and the reliable size W of the ring die are dealt with parameters, which normally do not change, and it is difficult for users to alter them, so they will certainly not be gone over right here. The pellet density is related to the raw material for granulation and additionally to the compression proportion of the ring die.

The greater the compression proportion, the stronger and denser the pellets will be. Nevertheless, for basic items, the pellet thickness is not very different, so the pellet density is not the main influencing criterion, so it will not be discussed way too much here. In other words, for the very same granulation raw material, the larger the pellet thickness, the shorter the pellet size.

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

Poultry feed production machines are powered by electrical energy, however oftentimes oil drive has actually ended up being essential. As most of us understand, the equipment works quickly and depends totally on the power belt, and oil is particularly important as the power supply of the equipment.


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

( 1) The supplier of the total collection of equipment with an outcome of 5 tons of concentrate recommends that you examine the major shaft and also blades of the poultry feed pellet machine initially to make sure that there is no product residue in the void.

( 2) The supplier of the small poultry feed manufacturing machine recommends that the customer requires to meticulously clean up the filter display in the oil filter.

( 3) Get rid of the oil block of the poultry feed manufacturing machine. Usually, the device of choice is: an effective hollow tube of a specific size, mostly made use of to clean up the impurities packed into the oil hole.

( 4) We often say that in addition to examining the above matters, we need to also check whether there is oil leakage at the refueling component. If the oil leakage is specifically severe, it will definitely result in no oil supply. The option to this problem is to include an oil liner.
