Challenge: There is a large impact from the coal flow and serious noise pollution.
Solution: Use wear-resistant ceramic drums (with a hardness of HRC 85) and low-noise idlers.
Case: The coal conveying line of a certain power plant uses a YTH-type electric drum (with a power of 90kW) and cooperates with polymer idlers. The annual maintenance cost is reduced from 1.2 million yuan to 400,000 yuan, and the noise is reduced from 85dB to 72dB.
