Brief Introduction Of Ring Die

Ring die is the key part of Ring Die Pellet Mill in the large scale pellet plant to produce animal feed, wood pellets, poultry feed,livestock feed,aqua feed, bio-mass pellet and other granules.

The quality of ring die plays an important role in making high quality pellets and high output,also can save much maintenance cost for pellet manufacturers.

LiangYou is a reliable ring die manufacturer who can supply you top quality ring dies .We can customized design for various brand of pellet mill, such as: CPM, Matador ,Muyang, Paladin, Promill, Buhler, Zhengchang, Mabrik, Matador, Sogem, Andritz Sprout, Yemmak, etc.We can also make as per customers' drawing.


  1. The specialized steel forge process provide high quality steel forges.

  2. With the 15years experience, the dies made by advanced special-purpose gundrill, ensuring precise size of die holes.

  3. The specialized key heat-treating process is carried out by advanced heat-treating equipment such as vacuum furnace.

  4. The professional design and marketing experience guarantee shape and depth of die ,hole and hole-opening rate, which can meet the different requirements of poultry and livestock feed and aqua feed.Thus greatly improve the quality and high efficiency of pelleting.

  5. Perfect sales and after-sales service meet requirement of user. 

Production process: 

1.Precision Machining--CNC 

machining center CNC machining center assure high dimensional accuracy,geometric tolerance and surface roughness.

2.Hole Machining--Germany gun drill 

Good quality gun drill equipment, tools and drilling hole software: 

1.Die hole position high accuracy, up to 15 seconds per circle. High accuracy of position ensures both high dimensional accuracy and uniformity of materials and uniformity in die wearing and forces of radial direction and peripheral direction.

2.High rotating speed and imported tools and cooling liquid ensures process conditions as drilling required.Thanks to such conditions, the processed die hole features small roughness, Ra 0.8 and smoothness, which can ensure pelleting output, quality and debugging convenience.

3.The application of drilling hole software is favorable to increase porosity of ring die and optimize its way of aperture and therefore pelleting output, quality and service life of die is guaranteed.

3.Vacuum Hardening

American vacuum furnace:High vacuum degree, no oxidation reaction in ring die surface, ensuring original smoothness of die hole inner surface ,has long service life and high quality.High cooling speed ensures more even distribution of carbide hardenability and uniformity of ring die.
