With the energetic advancement of modern aquaculture and also feed market, the demands for feed quality are obtaining higher and higher. For pellet feed created by poultry feed manufacturing machine, pellet size is a really important high quality assessment index.

Cool and also regular pellet feed not just satisfies the sales needs of feed producers, but likewise fulfills the actual reproducing requirements of customers. Pellets that are as well long, as well short or uneven are not for animal feeding. In actual production, the length 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 instance, granules with a diameter of 3 mm are typically generated with a size of 6 to 9 mm. Of course, according to actual customer demands as well as different feed selections, the size requirements are not necessarily within this range.

For that reason, in order to generate feed pellets that satisfy the needs or as close as possible to the demands, we will certainly talk about some aspects that impact the pellet length of the poultry feed pellet making machine and discover the corresponding control techniques to make it beneficial to the production needs, which is important for feed producers value. Based on years of experience in poultry feed granulator style as well as field debugging, we will discuss this issue from the adhering to facets.

1. Criteria influencing the poultry feed production machine itself:

The outcome of the poultry feed manufacturing 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 direct rate of the ring die is V (m/s), and also 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 number of openings is n (items), and the granulation size is L (mm),.

For the above formula, it is uncomplicated to evaluate the elements impacting the pellet size L of the poultry feed production machine:.

( 1) The impact of the outcome of the poultry feed production machine.

It can be seen from the formula that the pellet length L is symmetrical to the result Q. With other specifications consistent, the higher the yield, the longer the pellet, otherwise the shorter the pellet. Therefore, changing the outcome of the poultry feed pelletizer to fulfill details pellet size demands is a feasible option. In actual feed manufacturing, feed producers do the very same, in some cases giving up big quantities of output to meet pellet length demands. This concern will certainly be stated in the complying with conversation.


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

It can be seen from the formula that the pellet size L is inversely proportional to the ring die direct velocity V or the ring die direct speed n. When the feeding rate, that is, the output Q, continues to be constant, the much faster the ring die speed, the much shorter the instantaneously extruded pellets, as well as the other way around. For different dimensions of poultry feed pelletizers, the rotational rate of the ring die differs significantly.

Generally, the revolving speed of the small poultry feed making machine is high, as well as the rotating speed of the huge poultry feed manufacturing machine is low, however the direct speed of the ring die is controlled within a suitable array, normally between 6m/s ~ 9m/s, to satisfy the demands of granulation.


When the linear speed of the ring die is little, the top quality of the pellets is high, however the pellets may be longer than called for, and the line speed is too little, which will affect the outcome; when the linear speed of the ring die is high, although it is beneficial to enhance the outcome, the pellets might be shorter than the requirements, as well as the high quality of the pellets It will certainly become worse, which needs the feed supplier to pick its very own ring die line rate according to different feed varieties, as well as realize it by changing the transmission proportion of the poultry feed production machine transmission system.

( 3) Impact of ring die aperture and also porosity.

The ring die aperture D has no direct effect on the pellet length L, it has an effect on the length L along with the variety of openings N, that is, the size of the ring die opening up ratio, due to the fact that the opening proportion and also the square of the ring die diameter D and the number of openings N is proportional 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 rate of regarding 25%, and also a ring die has an opening rate of about 38%.

Generally speaking, the larger the pore size, the higher the open porosity. In actual production, specifically when generating small-diameter pellets, such as 1.8 mm shrimp, some individuals whine that the pellets are too long, which is triggered by the reasonably reduced opening rate of the ring die when the aperture is little. Among the services is to compromise part of the return, or to accomplish by enhancing the line speed of the ring die. Additionally, readjusting the cutter is reviewed below.

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

For the poultry feed production machine, the inner size D of the ring die as well as the effective size W of the ring die are taken care of criteria, which typically do not change, as well as it is not easy for individuals to transform them, so they will certainly not be reviewed below. The pellet thickness is related to the raw product for granulation as well as likewise to the compression proportion of the ring die.

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

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

Poultry feed manufacturing machines are powered by power, but oftentimes oil drive has ended up being crucial. As most of us understand, the tools functions quick and depends completely on the power belt, and oil is especially vital as the power supply of the tools.

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

( 1) The producer of the total collection of tools with a result of 5 tons of concentrate suggests that you examine the primary shaft and blades of the poultry feed pellet machine first to ensure that there is no material deposit in the gap.

( 2) The manufacturer of the tiny poultry feed manufacturing machine suggests that the individual needs to thoroughly cleanse the filter screen in the oil filter.

( 3) Get rid of the oil block of the poultry feed manufacturing machine. Usually, wood pellet machine in Comoros of selection is: an efficient hollow tube of a specific length, mainly used to clean the pollutants packed into the oil opening.

( 4) We often claim that along with checking the above issues, we ought to additionally examine whether there is oil leakage at the refueling part. If the oil leakage is especially severe, it will absolutely lead to no oil supply. The solution to this issue is to add an oil liner.
