The head pulley/sprocket is the primary drive component located at the discharge end. It transmits rotational force from the motor to the belt or chain, moving buckets upward for material discharge. It controls speed and direction of the conveying system.
Common materials include carbon steel, stainless steel, and cast iron. The choice depends on the application, such as corrosion resistance or strength requirements. Material grades like Q235B to Q345B (per GB/T 700) may be specified for heavy-duty use.
Selection involves matching parameters such as pulley diameter, face width, bore diameter, and maximum belt speed to your system's requirements. Consider load capacity, surface hardness for abrasive materials, and operating temperature. Always verify model-specific values with the manufacturer.
Regular inspection for surface wear, radial runout, and temperature rise is recommended. Ensure proper belt/chain tension and alignment. Replace worn components to prevent failure. Follow manufacturer guidelines for lubrication and servicing.
