1. Select high-quality wood pellet machine ring die materials Wear-resistant material: alloy steel (such as Cr12MoV, H13) of the ring die is preferred to improve the resistance to wear
Reasonable compression ratio: Select the compression ratio of the ring die according to the characteristics of the raw material (hardness, fiber content) to avoid excessive wear due to unreasonable design.
2. Standardize the operation process
Raw material pretreatment:
Ensure that the raw material is dry (water content is controlled at 10%-15%), and too high humidity will increase the friction resistance of the wood pellet machine ring die.
Remove metal, sand and other hard impurities in the raw material to prevent scratching the inner wall of the ring die.
Uniform feed: Avoid excessive or intermittent feed, reduce ring die wear caused by overload or idling.
Control temperature:
Excessive ring die temperature during operation will lead to metal softening and accelerated wear. Idling cooling is required before shutdown to avoid sudden cooling and heating.

3.Daily maintenance and maintenance
Regular cleaning:
Clean the residual material in the ring die hole immediately after shutdown to prevent hardening and clogging (especially for oily or viscous raw materials)
Use a soft brush or compressed air to clean and avoid metal tools scratching the ring die surface.
Lubrication protection:
Apply a food-grade lubricant or rust inhibitor (such as silicone oil) to the surface of the wood pellet machine ring die to reduce friction and prevent rust.
Wear check:
Regularly measure the ring die aperture, if the hole wall wear exceeds 0.2-0.3mm or the discharge particles are not uniform, it needs to be replaced in time.
4. Adjust running parameters
Matching power: Adjust motor power and roll pressure according to ring die specifications to avoid ring die deformation due to excessive pressure.
Control output: To avoid long-term overload operation, it is recommended to stop cooling inspection every 8 hours of operation.
5. Precautions
Equipment matching: Ensure that the ring die and roll size match to avoid improper clearance accelerated wear.
Preventive maintenance: Establish a regular maintenance plan, record the use time and wear of the wood pellet machine ring die.
Through the above measures, the ring die life can usually be extended by 30%-50%, greatly reducing production costs. The specific operations must be adjusted based on the device model and the manufacturer's suggestions.
