stainless steel ring die for pellet machine

 ♦ 2015 China Feed Industry Expo & Animal Production Promotion was held at Nanjing International Expo Center. the  Expo was organized by National Animal Husbandry Service and China Feed Industry Association.
 ♦ Many international copanies were take part in the exhibition, such as Muyang, DSM, Adisseo, Zhengchang, Buhler  and CP Group.
 ♦ The scope of the exhibition includes feed ingredients, feed and feed additives, animal feed, feed processing  machinery and equipment, animal health products, veterinary drugs, pharmaceutical additives, poultry processing  equipment, and animal husbandry machinery and equipment.

 To make sure the chicken cattle feed machine delivery to you at the best condition,  we adopt the considerate way  to  protect the equipment very well.  We consider our products just as our children. 

 1) How did you define your animal feed pellet machine model as 250 / 320 / 350 /420 / 508,  etc. ?

 The model is defined based on the diameter of the ring die mould.

 For example, mould 250 means that the diameter of the ring die is 250 mm. 

 2) If we only buy one set of cattle feed machine, could we produce feed for different kind of animal and poultry? 

 Yes. of course.  

 What we need to do is just have different size of ring die mould according to the requirement of different animal and  poultry.  and the replacement of the ring die mould is very easy. 

 3) what kind of raw material that the ring die mould is made of?

 There are two kinds of ring die mould in the market. one is made of carbon steel, the other is made of stainless  steel.   the former is cheaper than the latter.

 We adopt stainless steel ring die and press roller sheel in our machine.

 4) Is it possible that we only buy one set of feed pellet machine to produce animal feed? without other equipment?

 Should to say :  Yes, It's possible.

 but you'd better find the proper way to load and mix the raw material.  otherwise, you will have to do such jobs  by hands.

 5) What is the suitable moisture (water content) of the raw material that easy to make feed pellet?

 the ideal moisture range is from 15%  to 18% .

 6) What brand of motors you used in the machine?

 We use Siemens brand motor in our machine. please rest assured about the quality.

 7) what about the power, capacity, size and weight of the poultry feed manufacturing machine? 

 Please refer to the above technical parameter table to get the detail. 

 If you want the details of our smaller size of poultry feed manufacturing machine, please click here.

 8) will you dispatch engineer to install the cattle feed machine (production line)? 

 Yes. we will dispatch engineer to do the service just based on the requirement of customers. 

 9) where is your factory located? how could I get there? 

 Our factory is located in Zhengzhou, Henan, China. It's 30 km far from the airport. we will pick you up at the airport.

 1) What kind of animal or poultry that you will produce feed for? 

 2) What are your main raw material? 

 3) what about the capacity? (how many ton per hour or day or year?)

 4) are you the final user or you will sell the machine to others? 

 1) About the Compression Ratio of the ring die mould.

 define "L" as the effective hole length of the ring die.

 define "D" as the effective hole diameter of the ring die.

 the Compression Ratio = L / D.

 The higher Compression Ratio, the more compact that the animal poultry feed pellet will be, and the pelleting  speed will  be reduced accordingly.

 2)  Ring die failure cause analysis

 Pellet mill machine is the key equipment in poultry and animal feed pellet producing process. The ring die mould is  the heart part of pellet mill machine, and it's one the most easy wearing spare parts as well.

 Since the ring die mould work with friction all the time. the ring die mould will be wearing and finally failure along  with the throughput increasing. the handling capacity is one of the main performance index for the ring die mould.

 theoretically, one set of ring die mould and one pair of press roller could produce 2000 ton and 500 ton  feed pellet.  but in practice, even the poultry and cattle animal feed factory whose management were very well could reach to 1500 ton and 300 ton respectively. and for those poor-management one, the value is only 600 ton / 100 ton.

 After a period of working, the hole inside wall friction losses was increasing,
 A) the diameter of the hole increased, and the diameter of final product animal feed pellet exceed the specified  value.
 B) the scraggly of the hole inside wall get worse, the feed raw material will easy to block, the capacity will  decrease.
 C) the thickness of the hole wall will be reduced, the structural strength will be highly reduced.

 3) A number of reasons cause the ring die friction losses.

 A) the fineness of the chicken poultry cattle animal feed raw material.

 the more fineness of the raw material, the bigger superficial area of the  raw material, and the feed raw material  will more easily to absorb water from the steam, it's propitious to conditioning and forming.
 otherwise, too coarse granular size of the chicken poultry cattle animal feed raw material will increase the friction losses of the ring die.
 Generally, all of the feed raw material partical size should be more than 8 mesh, the proportion of partical that above 25  mesh should not less than 65%.

 for those high coarse fiber feed raw material, we should add some oil to reduce the friction, and the surface of the  final poultry animal feed pellet will look more smooth.

 B) the impurity in the raw material will accelerate the friction losses. hence the raw material cleaning is very  important.

 C) steam could soften the raw material, and make the oil content cell division, the oil in the cell will play a role of  lubrication when pelleting, and the capacity will be increased.

 Normally, the pressure of steam should be 0.2-0.4 MPa.
 for those high protein material, the pressure should be less accordingly.
 for the rich fiber material, the steam pressure should be higher. 

 under the function of steam, the water content in the raw material should be 16%-17%. the temperature should be  78-87 Celsius system.

 D) the space between the press roller and the ring die mould.
 It will speed up the friction if the space is too small. the ideal space is 0.2-0.4 mm.
 the space selection will depend on the diameter of the pellet. smaller diameter, smaller space.
 when we replace the ring die mould with a new one, the space should be set as lower value.
