ZOOMRY tail pulleys and bend pulleys are essential belt conveyor components located at the tail end and directional change points of the conveyor system. Unlike the drive/head pulley, the tail pulley is not attached to a driving mechanism — it turns freely with the Conveyor Belt, drawing power from the head end. Manufactured from 16Mn steel with 45#/40Cr shafts under ISO 9001 and CEMA standards, each pulley undergoes rigorous quality control including CNC four-roll rounding and ultrasonic flaw detection to ensure smooth belt tracking and extended service life.

What Are Tail Pulleys and Bend Pulleys?

In a belt conveyor system, tail pulleys and bend pulleys serve critical belt routing and tensioning functions. The tail pulley is positioned at the loading end of the conveyor, where material is fed onto the belt. It returns the belt from the carrying side to the return side and often doubles as a tensioning point to maintain proper belt tension. The bend pulley changes the direction of the belt at various points along the conveyor — commonly at the take-up section or near the drive station to increase wrap angle.

Both pulley types are free-rotating and rely on the drive pulley for power. Their smooth, balanced rotation is essential for preventing belt mistracking, reducing wear on the belt edges, and minimizing energy consumption. ZOOMRY tail and bend pulleys are available with smooth steel shells or rubber-lagged surfaces, in diameters from 200mm to 1,400mm, matching belt widths from 400mm to 2,400mm.

Applications

ZOOMRY tail pulleys and bend pulleys are deployed across a wide range of industries and conveyor configurations:

• Mining & Quarrying — heavy-duty tail and bend pulleys for ore, coal, and mineral handling in abrasive environments with high belt tensions.
• Cement Plants — pulleys designed for limestone, clinker, and raw meal conveying, with optional rubber lagging for dusty conditions.
• Ports & Terminals — corrosion-resistant configurations for coastal and high-humidity bulk material handling.
• Power Plants — reliable tail and bend pulleys for coal handling conveyors requiring low maintenance and high availability.

Our Pulley Advantages

1. The belt conveyor drum/pulley is made from large seamless steel for uniform strength and durability.
2. Flame cutting machines precisely cut the tube to exact specifications.
3. The pulley inner disc is welded with professional welding machines for structural integrity.
4. The shaft sleeve and disc are welded with a positioner to ensure precise alignment.
5. The outside circle is processed with a large drum lathe to guarantee even wall thickness.
6. We select #45 round steel and sleeves to ensure concentricity and reduce eccentric shaft force.
7. An inner bearing enlargement device is equipped to avoid bearing damage from beating during installation.
8. Static balance inspection is performed when the belt speed exceeds 2.5 m/s.
9. We can produce different types and standards of pulleys according to customer requirements.
