Ring hammer crushers are widely utilized in coal handling systems of coal-fired power plants to crush raw coal to the particle size required by coal mills. The ring hammers, liners, and crushing chambers are subjected to continuous high-speed impact and abrasive wear from coal and interbedded rocks, making them prone to wear, fracture, and reduced efficiency. Manufacturing liners with wear-resistant plates and applying high-alloy hardfacing to consumable parts like ring hammers can significantly enhance impact and wear resistance, thereby extending component service life.

For worn ring hammers, remanufacturing and repair processes can be applied to restore their original dimensions. This reduces spare parts consumption and equipment downtime, while improving the overall operational reliability of the crushing system.
