With the energetic development of modern tank farming as well as feed industry, the needs for feed quality are obtaining higher as well as higher. For pellet feed generated by poultry feed production machine, pellet length is an extremely vital top quality assessment index.

Cool as well as constant pellet feed not only satisfies the sales needs of feed manufacturers, however additionally satisfies the real breeding demands of customers. Pellets that are also long, as well brief or uneven are not conducive to pet feeding. In actual manufacturing, the length of the pellets generated by the poultry feed manufacturing machine is usually required to be 2 to 3 times the size of the pellets.

As an example, granules with a diameter of 3 mm are usually generated with a size of 6 to 9 mm. Naturally, according to real individual demands as well as different feed varieties, the size demands are not necessarily within this array.

As a result, in order to generate feed pellets that meet the requirements or as close as possible to the requirements, we will go over some elements that affect the pellet size of the poultry feed pellet making machine and locate the corresponding control methods to make it beneficial to the manufacturing needs, which is essential for feed suppliers significance. Based on years of experience in poultry feed granulator layout as well as field debugging, we will discuss this issue from the adhering to aspects.

1. Criteria influencing the poultry feed production machine itself:

The result of the poultry feed manufacturing machine is Q (kg/h), the inner size of the ring die is D (mm), the effective width of the ring die is W (mm), the straight speed of the ring die is V (m/s), and also the rotational rate 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), as well as 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 production machine:.

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

It can be seen from the formula that the pellet length L is proportional to the result Q. With other specifications consistent, the higher the return, the longer the pellet, otherwise the shorter the pellet. For that reason, changing the output of the poultry feed pelletizer to meet specific pellet size demands is a feasible alternative. In real feed production, feed producers do the same, in some cases sacrificing huge quantities of outcome to fulfill pellet length requirements. This problem will be mentioned in the adhering to discussion.

( 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 straight rate V or the ring die straight speed n. When the feeding speed, that is, the outcome Q, continues to be consistent, the faster the ring die rate, the shorter the instantly extruded pellets, and vice versa. For different sizes of poultry feed pelletizers, the rotational rate of the ring die varies considerably.

Usually, the turning speed of the tiny poultry feed making machine is high, as well as the rotating speed of the huge poultry feed manufacturing machine is reduced, however the direct speed of the ring die is regulated within an appropriate variety, typically in between 6m/s ~ 9m/s, to meet the requirements of granulation.


When the linear rate of the ring die is little, the quality of the pellets is high, yet the pellets might be longer than needed, and also the line speed is as well tiny, which will affect the output; when the linear rate of the ring die is high, although it is beneficial to boost the output, the pellets may be much shorter than the requirements, and also the quality of the pellets It will certainly worsen, which needs the feed supplier to select its own ring die line speed according to different feed selections, as well as understand it by altering the transmission proportion of the poultry feed manufacturing machine transmission system.

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

The ring die aperture D has no direct result on the pellet size L, it has an effect on the length L together with the variety 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 and also the number of openings N is symmetrical to the item of. The larger the porosity of the ring die, the shorter the pellets, and also vice versa, the longer the pellets. The aperture ratio of the ring die represents different ring die apertures. For example, a ring die has an opening rate of about 25%, as well as a ring die has an opening price of concerning 38%.

Generally speaking, the bigger the pore dimension, the higher the open porosity. In actual manufacturing, specifically when generating small-diameter pellets, such as 1.8 mm shrimp, some individuals grumble that the pellets are as well long, which is triggered by the fairly low opening rate of the ring die when the aperture is little. Among the remedies is to compromise part of the yield, or to accomplish by boosting the line rate of the ring die. Additionally, readjusting the cutter is reviewed below.

( 4) Influence of ring die internal diameter, effective size and also pellet density.


For the poultry feed manufacturing machine, the internal size D of the ring die and also the efficient size W of the ring die are repaired parameters, which usually do not transform, and it is not easy for users to transform them, so they will not be talked about here. The pellet thickness is related to the raw material for granulation as well as also to the compression ratio of the ring die.

The greater the compression ratio, the firmer and denser the pellets will be. However, for general products, the pellet thickness is not extremely different, so the pellet density is not the main affecting parameter, so it will not be discussed excessive below. Basically, for the same granulation resources, the larger the pellet density, the shorter the pellet size.

2. Just how to solve her comment is here -free phenomenon in the manufacturing procedure of the poultry feed pellet making machine?

Poultry feed production machines are powered by electrical power, but in a lot of cases oil drive has actually become vital. As all of us understand, the equipment functions fast as well as depends totally on the power belt, as well as oil is especially essential as the power supply of the devices.

Resolve the problem of no oil in the poultry feed manufacturing machine:.

( 1) The producer of the complete set of equipment with an output of 5 tons of concentrate recommends that you check the major shaft and blades of the poultry feed pellet machine first to make sure that there is no material residue in the space.

( 2) The maker of the little poultry feed production machine recommends that the individual requires to thoroughly clean up the filter screen in the oil filter.

( 3) Get rid of the grease block of the poultry feed manufacturing machine. Usually, the device of choice is: an efficient hollow tube of a particular length, mainly made use of to cleanse the contaminations packed right into the oil hole.

( 4) We usually claim that in addition to inspecting the above issues, we ought to likewise inspect whether there is oil leakage at the refueling component. If the oil leakage is specifically serious, it will most definitely result in no oil supply. The solution to this problem is to include an oil lining.
