Hollow shaft repair of mining ball mill: the low stress advantage of Daokedao laser cladding vs traditional welding
Date:2025-11-06 14:01     Source:daokedao     Browse:7

The hollow shaft of the mining ball mill bears huge loads and impacts from grinding media. Traditional electric welding repair requires a large amount of heat input, and the shaft body is prone to stress cracks. During operation, crack propagation can cause the shaft body to fracture, and the service life after repair is only 1-2 months.

The Daokedao laser cladding equipment adopts low stress cladding technology, with a heat input of only 1/8 of that of electric welding, no stress cracks in the shaft body, and a 50% increase in fatigue strength. Using high toughness wear-resistant alloy powder, the transition between the cladding layer and the substrate is smooth, and the impact resistance is excellent.

The service life of the repaired hollow shaft has been extended to 8-10 months, and the failure rate of the ball mill has been reduced by 90%. After adopting this technology, a mining enterprise has reduced equipment downtime losses by more than 800000 yuan per year, ensuring the efficiency of ore grinding.
