All types of idler rollers use high-quality idler-specific steel pipes, stamped bearing seats, and cold-drawn shafts. The stamped bearing seats are welded to the idler roller body using carbon dioxide gas shielded welding. Reliable dust-proof and rain-proof sealing measures must be provided at both ends of the roller, and lubrication is carried out using lithium-based grease.

All conveyor belts are equipped with dual cleaners, H-type and P-type, using polyurethane scraper blades. High molecular polyurethane scraper gap cleaners are installed at the tail and vertical tensioning device of each conveyor belt. The cleaners are equipped with pressure automatic adjustment control devices to ensure that the blade maintains proper pressure against the belt at all times, maintaining good contact with the belt to effectively remove materials adhering to the belt.

Belt conveyors must meet the requirements for long-term continuous operation. Startup, operation, and shutdown should be smooth and safely reliable. All belt conveyors are designed for full-load starting and braking. During continuous full-load operation, when the voltage is within 10% of the rated value, or the frequency varies within ±5% of the rated frequency, or both the voltage and frequency change simultaneously, but the absolute value of their combined variation does not exceed 10%, the belt conveyor should be able to start smoothly without damaging the equipment, with the full-load current not exceeding the rated current. When operating under design conditions, the rated capacity of the motor of the belt conveyor shall be not less than 120% of the power required for the maximum operating condition of the driven equipment.
