had you published this document about Feed Pellet Quality in oher place? then, Should you send me the reference?
Normally we use knifes for making pellet feeds and in my view knifes should be sharp enough to provide you required size of pellets if you are not going to crumble it after die. So its applicable if we have to make crumbs feed and for that I think we can use either worn or sharp knives or pusher as well. What do you suggest for 8mm pellets if not going to be crumbled after ?
Dear Sir, Your case study is excellent and will definitely helpfull to Pellet feed Manufactureres to restucture their knives as per their inputs or to replace knives by Pushers if maize based diet to achieve the better PDI%. Thanks & regards, Dr Jaydip Mulik
Every step during the manufacturing of feed pelleting is important and Author conducted a research on one of the steps during the pelleting process, cutting. This is a very well conducted research but still there is more scope with different formulation and length of pellet in different weather conditions. I commend the author for the quality research and also would like to encourage him to expand the scope of his research.
This article was published two years ago in FeedTech (AllAboutFeed) and last year in AFMA MATRIX. If somebody wants the references I would be more then happy to send it over. You have just to tell me in what reference are you interested and I will send you the one. Since this research was done with pusher 10 and 20 mm from the die surface, all pellets were as uniform as pellets cut with the sharp knife. Differences in length were +/- 2mm for 10mm pellet lenght and for 20mm pellet length a bit more. Here Im giving the point as well: Why do we have to have absolutely uniformed pellets? Is that the chicken that doesnt like non-uniformed pellets or +/- 2mm make a big nutritional difference?! I agree with Mr. Arshaq Ramzee that the scope of this research could of been expanded by different weather conditions.

A clear articles which gives practical idea about the sharp and worn out pellet knife and its effect on pellet quality. Thanks.
Hello, do you have some experience about cost of pellet mill production? I have high energy cost, how to optimize flow production?
Jordache, Please can you explain me better what do you mean by cost of pellet milk production? The production of the machinery or pelleting process itself?
the pellet process inself. Maybe a have a long flow of transport pellet.
Dear Miladinovici, i 've been late to send to you details about my transport lines. I have 5 elevators that transport pellets into bin(silo). i have 7.5kwh*5 elevators, at least 37.50 kwh electric energy. And also an vertical cooler under pellet mill, that have also 15kwh. i try to modify transport line to have low cost. And another problem is that my broken mill fooder( broiler starter, that i broken in smaching, have too much particle (floury appearance 35%), and i have to repelletized mill/feed. Do you now something about smashing feed technology?
hello, please help me to solve a big problem that i have at my factory pellet mill. in process of pelleting mill, at the inventory, rezult that are a lots lack of inventory. i dont have p[rocedures that specifing technological losses. i supose that are loss of moisture at the grinding grain process, cooling pellets, are losses at the grain transport and pellet transport. please help me if you have materials that establish procedures and studying the pellet mill process. Thanks and regards!!!! i want to specify that this damage is not due to theft, because the factory is equipped with cameras surveillance. please help me to discover process problems. Jordache
Dear Jordache, all the established feed producers within the EU must have the HACCP and GMP certified procedures. Certainly, all the companies should shape their procedures according to their own production and menagerial systems. As I can see your issue, the procedures must be established within the cooling systems (air speed control and air temperature) and as you have mentioned transport systems within the production conveying).
Friends, As a normal rule to follow based on the Good Practice of Manufacturing the lenght of any pellet could be about twice the geometric diameter, in other words, if we are processing poultry feed having 4 mm by using a 5/32" perforation pellet die the lenght of that particular pellet feed would be 8 mm, largest pellets will produce more fines and dust due to the fracture of the pellets into the system. Knife blade condition and sharpening are also an important aspects to produce good quality pellets. Thank you. Enrique Diaz, P.E. Sales/Service Process Engineer. R&D Equipment Company Fort Worth, TX
