With wood pellet machine in France of modern-day aquaculture and feed industry, the needs for feed quality are getting greater as well as higher. For pellet feed produced by poultry feed production machine, pellet length is an extremely crucial high quality evaluation index.

Neat and also consistent pellet feed not just satisfies the sales requirements of feed manufacturers, but also meets the real reproducing requirements of users. Pellets that are as well long, too brief or unequal are not for pet feeding. In real manufacturing, the size of the pellets created by the poultry feed manufacturing machine is generally required to be 2 to 3 times the size of the pellets.

For instance, granules with a size of 3 mm are normally created with a length of 6 to 9 mm. Of course, according to real customer requirements and also various feed selections, the length requirements are not necessarily within this range.

Consequently, in order to produce feed pellets that fulfill the demands or as close as possible to the requirements, we will certainly go over some factors that affect the pellet size of the poultry feed pellet making machine and also find the equivalent control approaches to make it beneficial to the production needs, which is very important for feed suppliers significance. Based on years of experience in poultry feed granulator layout and area debugging, we will certainly review this issue from the following facets.

1. Criteria impacting the poultry feed manufacturing machine itself:

The result of the poultry feed manufacturing machine is Q (kg/h), the inner diameter of the ring die is D (mm), the efficient width of the ring die is W (mm), the straight speed of the ring die is V (m/s), and the rotational speed of the ring die is n (r/ minutes), the ring die aperture is d (mm), the ring die opening up price is m, the number of openings is n (items), and also the granulation size is L (mm),.

For the above formula, it is uncomplicated to evaluate the aspects influencing the pellet length 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 size L is symmetrical to the outcome Q. With various other parameters consistent, the greater the return, the longer the pellet, otherwise the shorter the pellet. Consequently, readjusting the result of the poultry feed pelletizer to satisfy specific pellet length requirements is a possible alternative. In actual feed manufacturing, feed suppliers do the very same, often sacrificing large amounts of outcome to satisfy pellet size demands. This concern will be pointed out in the complying with discussion.

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


It can be seen from the formula that the pellet length L is vice versa proportional to the ring die linear rate V or the ring die linear rate n. When the feeding rate, that is, the outcome Q, remains constant, the quicker the ring die speed, the shorter the instantly extruded pellets, and vice versa. For different dimensions of poultry feed pelletizers, the rotational speed of the ring die varies substantially.

Generally, the rotating rate of the small poultry feed making machine is high, and the rotating rate of the big poultry feed manufacturing machine is reduced, yet the straight speed of the ring die is controlled within a suitable array, generally between 6m/s ~ 9m/s, to satisfy the requirements of granulation.


When the direct speed of the ring die is little, the top quality of the pellets is high, however the pellets may be longer than required, as well as the line speed is too small, which will certainly impact the result; when the linear rate of the ring die is high, although it is beneficial to boost the output, the pellets may be shorter than the requirements, and also the quality of the pellets It will worsen, which needs the feed supplier to choose its own ring die line speed according to different feed varieties, as well as recognize it by transforming the transmission ratio of the poultry feed production machine transmission system.

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

The ring die aperture D has no straight result on the pellet size L, it has a result on the size L together with the variety of openings N, that is, the size of the ring die opening up proportion, since the opening proportion and the square of the ring die diameter D and 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 vice versa, the longer the pellets. The aperture ratio of the ring die corresponds to different ring die apertures. As an example, a ring die has an opening price of regarding 25%, and also a ring die has an opening price of concerning 38%.

Normally talking, the larger the pore size, the higher the open porosity. In actual production, especially when creating small-diameter pellets, such as 1.8 mm shrimp, some users grumble that the pellets are too long, which is caused by the relatively reduced opening price of the ring die when the aperture is little. One of the options is to compromise part of the yield, or to attain by increasing the line rate of the ring die. In addition, adjusting the cutter is reviewed listed below.

( 4) Influence of ring die inner diameter, reliable size as well as pellet density.

For the poultry feed production machine, the internal diameter D of the ring die as well as the effective width W of the ring die are taken care of parameters, which usually do not transform, and it is difficult for individuals to transform them, so they will certainly not be gone over below. The pellet thickness is connected to the raw product for granulation as well as also to the compression proportion of the ring die.

The greater the compression proportion, the stronger as well as denser the pellets will certainly be. However, for basic products, the pellet density is not extremely various, so the pellet density is not the main affecting criterion, so it will not be gone over too much below. In short, for the same granulation raw material, the larger the pellet thickness, the much shorter the pellet size.

2. Exactly how to fix the oil-free phenomenon in the production process of the poultry feed pellet making machine?

Poultry feed production machines are powered by electricity, yet in most cases oil drive has become necessary. As most of us know, the tools works quickly as well as depends totally on the power belt, and oil is particularly essential as the power supply of the devices.

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

( 1) The maker of the total set of equipment with an outcome of 5 lots of concentrate recommends that you check the primary shaft and blades of the poultry feed pellet machine initially to make sure that there is no material residue in the void.

( 2) The maker of the tiny poultry feed production machine advises that the customer needs to very carefully clean the filter screen in the oil filter.

( 3) Eliminate the oil block of the poultry feed production machine. Generally, the device of choice is: an effective hollow tube of a specific length, mainly utilized to cleanse the pollutants packed right into the oil hole.

( 4) We typically claim that in addition to examining the above matters, we must additionally check whether there is oil leak at the refueling part. If the oil leakage is particularly serious, it will most definitely bring about no oil supply. The option to this problem is to add an oil lining.
