With the energetic development of modern aquaculture as well as feed market, the requirements for feed quality are getting higher as well as greater. For pellet feed created by poultry feed manufacturing machine, pellet length is a really important high quality assessment index.

Neat and also consistent pellet feed not just fulfills the sales needs of feed producers, however additionally satisfies the actual breeding requirements of users. Pellets that are also long, as well short or irregular are not for pet feeding. In real manufacturing, the size of the pellets generated by the poultry feed production machine is usually needed to be 2 to 3 times the diameter of the pellets.

As an example, granules with a size of 3 mm are normally produced with a length of 6 to 9 mm. Certainly, according to actual customer requirements as well as different feed selections, the length requirements are not necessarily within this range.

As a result, in order to generate feed pellets that meet the requirements or as close as feasible to the requirements, we will certainly review some aspects that influence the pellet length of the poultry feed pellet making machine and also discover the equivalent control techniques to make it beneficial to the production requires, which is important for feed producers relevance. Based upon years of experience in poultry feed granulator style and also field debugging, we will certainly review this issue from the complying with facets.

1. Specifications impacting the poultry feed manufacturing machine itself:

The outcome of the poultry feed manufacturing machine is Q (kg/h), the internal size of the ring die is D (mm), the reliable size of the ring die is W (mm), the linear 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 rate is m, the variety of openings is n (pieces), and also the granulation size is L (mm),.

For the above formula, it is not difficult to analyze the factors affecting the pellet length L of the poultry feed manufacturing machine:.

( 1) The influence 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 parameters constant, the greater the yield, the longer the pellet, otherwise the shorter the pellet. Consequently, readjusting the output of the poultry feed pelletizer to fulfill certain pellet size requirements is a feasible option. In real feed manufacturing, feed manufacturers do the exact same, occasionally giving up huge quantities of output to fulfill pellet length requirements. This problem will be pointed out in the complying with 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 symmetrical to the ring die direct speed V or the ring die straight speed n. When the feeding rate, that is, the output Q, stays continuous, the much faster the ring die speed, the shorter the instantaneously extruded pellets, and also vice versa. For various dimensions of poultry feed pelletizers, the rotational rate of the ring die varies considerably.

Usually, the revolving rate of the small poultry feed making machine is high, and also the rotating rate of the huge poultry feed manufacturing machine is reduced, but the straight speed of the ring die is regulated within an ideal range, usually in between 6m/s ~ 9m/s, to fulfill the requirements of granulation.


When the straight speed of the ring die is tiny, the top quality of the pellets is high, but the pellets may be longer than required, and also the line speed is too little, which will certainly impact the result; when the direct rate of the ring die is high, although it is beneficial to improve the output, the pellets might be shorter than the demands, and also the quality of the pellets It will become worse, which requires the feed producer to choose its very own ring die line speed according to different feed varieties, and also recognize it by transforming the transmission ratio of the poultry feed production machine transmission system.

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

The ring die aperture D has no straight effect on the pellet length L, it has an impact 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 ratio as well as the square of the ring die diameter 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 also the other way around, the longer the pellets. The aperture ratio of the ring die represents various ring die apertures. As an example, a ring die has an opening price of concerning 25%, and also a ring die has an opening rate of regarding 38%.

Generally talking, the larger the pore size, the higher the open porosity. In pellet mill in Egypt , especially when generating small-diameter pellets, such as 1.8 mm shrimp, some individuals grumble that the pellets are also long, which is caused by the fairly low opening price of the ring die when the aperture is little. Among the options is to give up part of the yield, or to attain by boosting the line speed of the ring die. In addition, changing the cutter is discussed below.

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

For the poultry feed manufacturing machine, the internal diameter D of the ring die and also the reliable size W of the ring die are dealt with parameters, which normally do not change, as well as it is hard for individuals to change them, so they will not be discussed here. The pellet density is related to the raw material for granulation and additionally to the compression proportion of the ring die.

The higher the compression ratio, the stronger as well as denser the pellets will be. Nevertheless, for basic products, the pellet thickness is not very various, so the pellet thickness is not the main influencing specification, so it will not be talked about too much below. In short, for the exact same granulation raw material, the bigger the pellet thickness, the shorter the pellet length.

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

Poultry feed manufacturing machines are powered by electrical power, but in a lot of cases oil drive has come to be necessary. As we all recognize, the equipment works fast and also depends completely on the power belt, and oil is specifically important as the power supply of the tools.

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


( 1) The producer of the full set of tools with an outcome of 5 lots of concentrate recommends that you check the main shaft and rotor of the poultry feed pellet machine first to guarantee that there is no product residue in the void.

( pellet mill for sale ) The manufacturer of the little poultry feed production machine recommends that the customer requires to meticulously cleanse the filter screen in the oil filter.

( 3) Get rid of the grease block of the poultry feed production machine. Normally, the device of choice is: an effective hollow tube of a certain size, mainly utilized to clean the impurities stuffed into the oil opening.

( 4) We typically claim that along with examining the above issues, we need to likewise examine whether there is oil leakage at the refueling component. If the oil leak is specifically serious, it will definitely result in no oil supply. The remedy to this issue is to include an oil lining.
