In biomass pellet machine ring die, alloy steel is usually more durable ‌. The following is a specific comparison of various materials:
‌1. Alloy steel ring die:
Features: alloy steel has high hardness and wear resistance, can withstand high temperature and high pressure.
Service life: alloy steel ring die in normal use, generally can work for about 1000 hours, strong durability.
Application scenario: suitable for the production of long-term high-frequency use of the ring die, especially for the occasion of high wear resistance and hardness requirements.
‌2. Carbon steel ring die:
Characteristics: carbon steel strength and hardness are relatively high, but wear resistance and corrosion resistance is poor, easy to be eroded by moisture and chemical substances.
Disadvantages: require frequent maintenance and replacement, so in the service life may not be as good as alloy steel.
‌3. Stainless steel ring die:
Characteristics: Stainless steel has excellent corrosion resistance and high temperature resistance, but the wear resistance and toughness are slightly insufficient.
Application scenario: It is more suitable for occasions that require corrosive environment, and may not be the best choice in terms of wear resistance.
‌4.Other materials:
Such as alloy cast iron, ceramics, cemented carbide, etc., these materials may also be used as materials for pellet machine ring die in some specific occasions, but they have advantages and disadvantages, and are not necessarily the most durable choice.
In summary, alloy steel ring dies are generally considered to be the more durable choice in biomass pellet machine ring dies because of their high hardness, wear resistance and ability to withstand high temperature and pressure.
