Challenge: The underground environment is humid and full of dust. Metal idlers are prone to corrosion and wear, and traditional drums require frequent maintenance.
Solution: Use polymer idlers (with strong corrosion resistance and 5-7 times enhanced wear resistance) and explosion-proof electric drums (in compliance with the MT/T 990 standard).
Case: A certain coal mine uses a YTH-type electric drum (with a power of 75kW and a diameter of 500mm) to drive the convey, and cooperates with diamond-patterned rubber-coated idlers to achieve a 20° inclination conveyance. This reduces the downtime for maintenance by 40% and lowers the energy consumption by 18%.
