Chinese and English names

English:Ring Die Made of 20CrMnTi Alloy Steel（Model 560 Pellet Mill）

Chinese:560 Special for pellet machine 20CrMnTi Alloy steel ring die material:20CrMnTi Alloy carburizing steel adapting equipment:560 Series ring die pellet machines (common to feed pellet machines and biomass wood pellet machines)

2. Core advantages of materials (20CrMnTi Detailed explanation of alloy steel)

High strength + High toughness combined with ordinary carbon steel ring die has high hardness but is easy to crack, while pure toughness steel has poor wear resistance;20CrMnTi Chromium-manganese-titanium alloy steel has undergone carburizing and quenching heat treatment. The surface layer has high hardness and wear resistance, and the matrix core has strong toughness. It is not easy to break or collapse when it withstands continuous extrusion impact during production, which greatly reduces the risk of mold explosion and shutdown.

The wear-resistant service life is doubled. The chromium and manganese alloy elements inside the steel improve the wear resistance. For materials containing impurities such as sawdust, straw, and mixed feed, the loss rate of the inner wall of the die hole is much lower than that of ordinary materials. 45# Steel and ordinary alloy steel ring dies have longer replacement cycles for long-term continuous production.

It is temperature-resistant and fatigue-resistant, and is suitable for continuous mass production of pellet machines that are exposed to high-temperature extrusion environments for long periods of time. This material is not easy to soften and deform under high temperatures.twenty four The continuous extrusion of the production line for hours is not prone to oval die holes or grooves on the inner wall, and the particle molding consistency is stable.

High machining accuracy, smooth material discharging, precision CNC drilling after one-piece forging and forming, the inner wall of the die hole is smooth and burr-free, the material extrusion resistance is small, and it is not easy to block the mold; after carburizing treatment, the inner wall is not easy to adhere to agglomerated raw materials, making cleaning and maintenance easier.

3. Product functions and applicable scenarios

core role

The ring die is the core molding accessory of the pellet machine. It cooperates with the pressure roller to extrude the powdery and crushed materials into uniform cylindrical particles, which directly determines the particle forming rate, finished product hardness and discharge speed.

Adaptable materials

Livestock feed: pig, chicken, cattle, sheep, fish and shrimp compound feed, pasture feed

Biomass fuel: wood chips, bamboo powder, straw, rice husk, palm shell pellets

Others: organic fertilizer granules, mushroom culture media granules, etc.

Adapt to equipment working conditions

560 Horizontal ring-die pellet machine is suitable for continuous mass production of small and medium-sized feed mills, biomass fuel processing plants, and organic fertilizer production lines.

4. Customized support

Hole diameter customization: can be processed according to finished product requirements 2.0mm/3mm/4mm/6mm/8mm/10mm/12mm Various die hole diameters;

Customized compression ratio: Adjust the compression ratio of the ring die according to the material characteristics (low compression ratio for feed, high compression ratio for biomass fuel) to solve the problems of loose particles, difficulty in molding, and slow discharge;

Size customization: can be customized according to the original factory 560 The standard size of the equipment is reproduced, and the inner diameter, width, and installation positioning holes can also be adjusted according to the modified equipment;

Process customization: supports deep hole polishing, double-layer enhanced heat treatment, and reinforced ring molds specifically for materials with high impurities and high hardness.

5. Advantages of use

Higher production efficiency. The mold holes are smooth and wear-resistant, and the discharging resistance is small. The hourly production capacity is increased under the same motor power. It is not easy to block the mold and reduces frequent shutdowns and unblocking time;

The quality of the finished particles is stable, the mold hole is not easy to deform in the long term, the output particles are uniform in length and firmness, and there is no excessive broken powder or hollow particles, which improves the appearance of the finished product;

The overall cost of use is lower. Although the purchase price is higher than that of ordinary carbon steel ring molds, the wear resistance life is improved. 50% The above can reduce frequent purchasing, disassembly, assembly and replacement labor costs, which is suitable for twenty four hourly continuous production plant;

High disassembly and assembly matching and strict benchmarking 560 The original installation dimensions of the pellet machine, positioning holes, flange thickness, and inner and outer diameters are accurately adapted. No grinding or modification is required, and the machine can be used after replacement.

6. Daily maintenance and replacement tips

Regular inspection: daily observation of die hole wear, inner wall grooves, and ring die surface cracks; if there are many sand and gravel impurities in the material, it is recommended to clean the die hole daily;

Maintenance method: Before stopping the machine, transport a small amount of oil raw material to lubricate the mold holes to prevent the material from drying out and clogging the mold; if the machine is shut down for a long time, all mold holes need to be cleaned and anti-rust oil applied;

Replacement standards: When deep grooves appear on the inner wall of the die hole, a large amount of particles are crushed, production capacity drops significantly, or fine cracks appear in the ring die, it is recommended to replace it immediately to prevent the ring die from bursting during production and damaging the pressure roller and main machine.
