With the strenuous development of modern-day aquaculture and feed market, the demands for feed top quality are obtaining higher and greater. For pellet feed produced by poultry feed production machine, pellet length is an extremely essential quality assessment index.

Cool as well as constant pellet feed not only meets the sales needs of feed makers, yet also meets the real breeding demands of customers. Pellets that are too long, also brief or irregular are not for animal feeding. In real manufacturing, the length of the pellets generated 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 size of 3 mm are typically produced with a length of 6 to 9 mm. Obviously, according to actual customer requirements and various feed selections, the size needs are not necessarily within this range.

Consequently, in order to create feed pellets that satisfy the needs or as close as possible to the needs, we will talk about some aspects that influence the pellet length of the poultry feed pellet making machine and also find the corresponding control techniques to make it beneficial to the production needs, which is necessary for feed manufacturers value. Based upon years of experience in poultry feed granulator style and field debugging, we will discuss this issue from the adhering to aspects.

1. Specifications influencing the poultry feed production machine itself:

The outcome of the poultry feed manufacturing machine is Q (kg/h), the internal diameter of the ring die is D (mm), the effective size of the ring die is W (mm), the straight rate of the ring die is V (m/s), and also the rotational speed of the ring die is n (r/ min), the ring die aperture is d (mm), the ring die opening up rate is m, the variety of openings is n (pieces), as well as the granulation size is L (mm),.

For the above formula, it is uncomplicated to analyze the variables influencing the pellet length L of the poultry feed manufacturing machine:.

( 1) The influence of the outcome of the poultry feed manufacturing machine.

It can be seen from the formula that the pellet length L is symmetrical to the result Q. With various other specifications constant, the higher the yield, the longer the pellet, or else the much shorter the pellet. Therefore, readjusting pellet machine in Brunei of the poultry feed pelletizer to fulfill particular pellet length requirements is a possible option. In actual feed manufacturing, feed manufacturers do the exact same, sometimes sacrificing big quantities of output to meet pellet size demands. This issue will certainly be discussed in the adhering to conversation.

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

It can be seen from the formula that the pellet length L is inversely symmetrical to the ring die linear rate V or the ring die linear velocity n. When the feeding speed, that is, the output Q, continues to be constant, the much faster the ring die rate, the much shorter the instantly extruded pellets, as well as the other way around. For different sizes of poultry feed pelletizers, the rotational rate of the ring die varies substantially.

Usually, the revolving speed of the little poultry feed making machine is high, and the rotating rate of the big poultry feed production machine is low, but the direct rate of the ring die is managed within an ideal variety, usually between 6m/s ~ 9m/s, to satisfy the demands of granulation.


When the linear rate of the ring die is small, the high quality of the pellets is high, but the pellets might be longer than needed, and the line speed is also tiny, which will certainly affect the result; when the straight rate of the ring die is high, although it is beneficial to improve the output, the pellets might be much shorter than the needs, as well as the high quality of the pellets It will worsen, which needs the feed maker to choose its own ring die line speed according to different feed varieties, and also understand it by changing the transmission ratio of the poultry feed manufacturing 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 size L along with the variety of openings N, that is, the dimension of the ring die opening up ratio, because the opening proportion and the square of the ring die size D as well as the number of openings N is symmetrical to the product of. The larger the porosity of the ring die, the much shorter the pellets, and vice versa, the longer the pellets. The aperture ratio of the ring die represents various ring die apertures. For instance, a ring die has an opening price of about 25%, and a ring die has an opening rate of regarding 38%.

Usually talking, the larger the pore size, the higher the open porosity. In actual production, especially when generating small-diameter pellets, such as 1.8 mm shrimp, some users grumble that the pellets are as well long, which is brought on by the fairly low opening price of the ring die when the aperture is small. One of the services is to compromise part of the return, or to achieve by enhancing the line speed of the ring die. In addition, changing the cutter is discussed below.

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

For the poultry feed production machine, the inner diameter D of the ring die and also the reliable size W of the ring die are repaired parameters, which typically do not alter, and it is hard for individuals to change them, so they will not be reviewed right here. The pellet thickness is connected to the raw material for granulation as well as likewise to the compression ratio of the ring die.

The higher the compression proportion, the firmer as well as denser the pellets will be. However, for basic products, the pellet thickness is not very different, so the pellet density is not the main affecting parameter, so it will not be discussed way too much here. In other words, for the same granulation resources, the larger the pellet thickness, the much shorter the pellet size.

2. Exactly 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 electrical power, however in most cases oil drive has actually ended up being vital. As we all know, the tools works quickly and depends completely on the power belt, and also oil is particularly essential as the power supply of the devices.

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

( 1) The maker of the total set of devices with an output of 5 lots of concentrate advises that you examine the main shaft and also blades of the poultry feed pellet machine initially to ensure that there is no material residue in the space.

( 2) The supplier of the small poultry feed production machine advises that the user requires to carefully clean the filter screen in the oil filter.


( 3) Eliminate the grease block of the poultry feed production machine. Generally, the tool of option is: a reliable hollow tube of a particular length, mostly made use of to cleanse the contaminations packed right into the oil hole.

( 4) We frequently claim that in addition to checking the above matters, we should additionally examine whether there is oil leakage at the refueling component. If the oil leak is particularly severe, it will definitely result in no oil supply. The service to this issue is to add an oil lining.
