Pellet Mill Ring Die
Application: Ring die for pellet machine in poultry feed, livestock feed, aqua feed, bio-mass pellet machine, etc. We could offer you OEM high chrome steel ring die, Such as for CPM, Matador, Muyang, Paladin, Promill, Buhler, Zhengchang, Mabrik, Matador, Sogem, Andritz Sprout, Yemmak, etc. pellet mill with different specification. Features of our ring die: 1. Made 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. 3. Ring die can be produced up to 300mm-1500mm in diameter and 500mm in height. 4. In ring die processing, full automatic control, one-time molding for die hole, high smoothness. Advantages: 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. Features of our production process: 1. Material refining technology,fewer impurities, high purity, largely reducing harmful elements content (such as elements S,P ), thus comprehensive mechanical performance of material is raised. 2. Through roll forging, material is processed and strengthened and material fibre is complete and uniform, which increases integrated mechanical performance of material. 3. FDSP Company has the world advanced forging equipment and technology,electronic data processing systems and perfect quality control system. 4. Ring die blank,generally chromiumalloy roll forgings, some factories use 45 ordinary carbon steel. 5. Hardness of blank must be controlled, ranging from HB170 to HB220. If the hardness is too high, the drill is easy to break and happens with die hole when drilling. If hardness is too low, the surfacefinish of die hole will be not good. 6. In order to control blank inner material uniformity, every blank must be carried out with fault detection, which can avoid defects such as flaw, pore-free,crackle and inclusions etc. 7. After machining and heat treatment process, hardness of ring die can be up to HRC 52-58 (inner diameter less than 350mm), HRC50-56 (inner diameter more than 350mm), more wearable and anti-corrosion. 8. In order to control hardness uniformity of ring die after heat treatment, we choose more than three points in each part of trisection of peripheral direction to test hardness and take average. The difference of hardness value between each part should not be higher than HRC4. 9. According to the principle of metal material science combined with gas quenching and C, Cr, Mn, Ni, V elements content is optimized, forming the standard of ring die. Relationship between die hole structure and pelleting: Straight hole and release stepped hole is suitable for compound feed processing External conical hole suitable for the processing of high-fibre feed like de-fat chaff Internal conical hole and compression-type stepped hole applicable for the process of herbage powder feed of light proportion We should try to avoid using release stepped hole(pressure-relief vent) Because discharing is not easy for holes in the rows of the edge of ring die, pressure-relief vent is designed there.
