Product Details

CPM pellet press die characteristics 
1.Advanced, automatic ring die processing technology: Full automatic CNC ring die drilling machine and vacuum heat treatment technology ensure the quality and working life of ring dies.
2.Rich ring die processing experience ensures the depth and opening ratio of the hole of ring die which can satisfy different requirements of poultry, livestock and aqua feed, thus improves the pelleting efficiency.
3.The surface of ring die is of good smoothness, high hardness, and the completed pellets are of good shape and neat appearance.
4.Quick discharge, high output and the production efficiency of the same size are much higher than ring dies of other brands.
5.Different types and hole diameters can be processed.

CPM pellet press die customization:
We (FDSP) can manufacture the pellet ring dies of different materials, types and hole diameters which are suitable for all top brand pelletizers, such as ANDRITZ, CPM, BUHLER, ZHENGCHANG, MUYANG, SHENDE etc.
Please offer the drawing and specifications of ring dies if you need.


Dies-steel mould
Our dies are manufactured in the following steels:
· X46Cr13 (i.e."stainless" steel or "chrome-steel") 
· 20MnCr5 (i.e."alloy" steel)
· 18NiCrMo5 (i.e. similar to 20MnCr·5 but with a higher alloy content).
The X46Cr13 steel dies are vacuum / through hardened. The heat treatment achieves 53-55HRc hardness on the surface and in the core. The high chrome content makes it corrosion resistant. Although it costs more than a normal alloy, X46Cr13 is by far the most common material used through out the feed milling industry.


Pellet press dies

Dies made in 20MnCr5 and18 NiCrMo5 steel, on the other hand, are case hardened to obtain 60-62HRc hardness for approximately 0.8-1.2mm. Under the case hardened layer the steel remains malleable and therefore less brinle. The dies made of this steel are more resistant for pelleting extremely difficult fibre-rich products such as beet pulp, alfalfa, straw and hay.

Dies-perfect drilling

FDSP dies have an extremely precise and regular perforation: the "honey comb" layout of the holes is faultless.

Deep hole via gun drill drilling: ring die holes array evenly, uniform wall thickness between holes, to ensure ring die works successfully in pellet mill with smooth surface of pellet. It is important to upgrade smooth and polish level of ring die holes in order to decrease temperature difference, lower energy consumption, raise capacity, and reduce loss of nutrition FDSP reach international advanced level relate to hardness of ring die, evenness and smoothness of holes.
