Pellet Die & Ring Die & Mill Die(for Cpm Matador Muyang Paladin Promill Buhler
FDSP can manufacture the 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.
FDSP 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 ring dies
Pellet Diesmade 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 pellet mill dies made of this steel are more resistant for pelleting extremely difficult fibre-rich products such as beet pulp, alfalfa, straw and hay.
FDSP ring 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.
Vacuum heat treatment
1.Suitable hardening temperature of vacuum furnace ensures higher hardness and impact toughness.
2.Suitable drawing temperature ensures no cracks of ring dies and little wear of hole and surface, which improves the workinglife.
3.In same loading, adding backfill air pressure will boost die's cooling and hardness.
4.CNC control technology ensures the stability of ring dies.
Feature of our ring die:
1Made of imported high-carbon high-chromium stainless billet steel,optimization carbon,thus enhancing wearing and corrosion resistance and hardness.
2 It can deal with all kinds of die hole over &1.2mm (&1.2mm included) and compression ratio.
3Ring die can be produced up to 300mm-1500mm in diameter and 500mm in height.
4In ring die processing, full automatic control, one-time molding for die hole, high smoothness.
Frist class forging material,fine heat treatment,advanced 4 shaft gundrill. Material:high chrome steel material, for various famous pellet mill.
