With the vigorous development of modern aquaculture as well as feed market, the needs for feed high quality are getting higher as well as higher. For pellet feed generated by poultry feed production machine, pellet length is an extremely crucial quality examination index.

Cool as well as consistent pellet feed not only fulfills the sales requirements of feed makers, however additionally meets the actual breeding needs of individuals. Pellets that are as well long, as well brief or unequal are not conducive to pet feeding. In actual manufacturing, the length of the pellets generated by the poultry feed production machine is normally required to be 2 to 3 times the diameter of the pellets.

For instance, granules with a size of 3 mm are generally generated with a size of 6 to 9 mm. Naturally, according to real user needs as well as various feed ranges, the length requirements are not necessarily within this range.

Consequently, in order to produce feed pellets that meet the needs or as close as feasible to the requirements, we will go over some elements that influence the pellet length of the poultry feed pellet making machine as well as discover the equivalent control methods to make it beneficial to the manufacturing needs, which is essential for feed suppliers significance. Based upon years of experience in poultry feed granulator style and field debugging, we will certainly discuss this issue from the following facets.

1. Specifications affecting the poultry feed production machine itself:

The output of the poultry feed production machine is Q (kg/h), the inner size of the ring die is D (mm), the efficient width of the ring die is W (mm), the direct rate of the ring die is V (m/s), and the rotational rate of the ring die is n (r/ minutes), the ring die aperture is d (mm), the ring die opening rate is m, the number of openings is n (pieces), and also the granulation size is L (mm),.

For the above formula, it is not difficult to assess the variables influencing the pellet size L of the poultry feed manufacturing machine:.

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

It can be seen from the formula that the pellet size L is symmetrical to the result Q. With various other specifications constant, the greater the yield, the longer the pellet, or else the much shorter the pellet. Consequently, readjusting the output of the poultry feed pelletizer to meet certain pellet length demands is a feasible option. In real feed manufacturing, feed suppliers do the exact same, occasionally compromising big amounts of outcome to meet pellet length needs. This issue will be discussed 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 vice versa symmetrical to the ring die direct speed V or the ring die straight speed n. When https://presspelletmachine.com feeding speed, that is, the output Q, remains continuous, the faster the ring die rate, the shorter the instantaneously extruded pellets, as well as vice versa. For different dimensions of poultry feed pelletizers, the rotational rate of the ring die differs greatly.

Generally, the rotating rate of the small poultry feed making machine is high, as well as the revolving speed of the huge poultry feed production machine is reduced, however the direct rate of the ring die is managed within an ideal variety, typically between 6m/s ~ 9m/s, to meet the demands of granulation.


When the linear rate of the ring die is small, the quality of the pellets is high, but the pellets may be longer than called for, and also the line rate is too small, which will influence the outcome; when the linear speed of the ring die is high, although it is beneficial to boost the outcome, the pellets may be much shorter than the demands, as well as the top quality of the pellets It will become worse, which calls for the feed maker to pick its own ring die line speed according to various feed selections, and understand it by transforming 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 impact on the length L along with the variety of openings N, that is, the dimension of the ring die opening proportion, due to the fact that the opening proportion as well as the square of the ring die size D as well as the number of openings N is proportional to the item of. The larger the porosity of the ring die, the shorter the pellets, as well as 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 price of regarding 25%, and a ring die has an opening rate of concerning 38%.

Normally talking, the bigger the pore size, the greater the open porosity. In real production, especially when creating 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 rate of the ring die when the aperture is tiny. Among the services is to compromise part of the return, or to accomplish by increasing the line rate of the ring die. Additionally, changing the cutter is talked about listed below.

( 4) Impact of ring die internal diameter, efficient width and pellet thickness.

For the poultry feed production machine, the internal size D of the ring die and the reliable width W of the ring die are fixed criteria, which usually do not transform, and it is hard for individuals to change them, so they will not be reviewed here. The pellet thickness is related to the raw product for granulation as well as also to the compression proportion of the ring die.

The greater the compression ratio, the stronger and denser the pellets will be. However, for general products, the pellet density is not really various, so the pellet thickness is not the main influencing parameter, so it will not be discussed excessive below. Simply put, for fish feed pellet machine , the bigger the pellet density, the shorter the pellet size.

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

Poultry feed production machines are powered by electricity, but oftentimes oil drive has ended up being necessary. As all of us understand, the equipment functions quick and also depends completely on the power belt, and oil is particularly vital as the power supply of the tools.

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


( 1) The producer of the total set of equipment with a result of 5 tons of concentrate suggests that you check the main shaft and blades of the poultry feed pellet machine initially to make sure that there is no product deposit in the gap.

( 2) The supplier of the tiny poultry feed manufacturing machine advises that the customer needs to carefully clean the filter display in the oil filter.

( 3) Eliminate the oil block of the poultry feed manufacturing machine. Typically, the device of choice is: an effective hollow tube of a specific length, primarily used to clean the contaminations packed right into the oil opening.

( 4) We often claim that in addition to inspecting the above issues, we should also examine whether there is oil leak at the refueling component. If the oil leak is particularly severe, it will definitely result in no oil supply. The option to this problem is to include an oil liner.
