Tail Pulley

Built for the tail return section of fixed belt conveyors, YUFENG Tail Pulley combines a thick seamless steel shell, integrated rubber lagging and a reinforced forged shaft to handle continuous belt tension and impact loads. Its heavy-duty construction helps prevent shaft deformation, lagging failure and bearing jamming, providing reliable reversing support for medium- and heavy-duty bulk conveying systems.

Material & Production Craft

Heavy-Duty Pulley Body for Tail Conveyor Sections

All raw materials used for YUFENG products are sourced from qualified suppliers and strictly inspected before production. The pulley cylinder uses thickened Q235 seamless steel pipe with sandblasting and epoxy anti-corrosion treatment, providing reliable resistance against muddy water, alkaline ash and coastal salt fog. The surface is covered with high-wear NR/SBR rubber lagging with 68±5 Shore A hardness, providing stable belt contact and reducing friction loss during continuous return-side operation.

Reinforced Shaft and Bearing Configuration

The central shaft is manufactured from solid C45 forged alloy steel and processed through CNC machining and integral quenching and tempering to improve bending resistance under continuous belt tension. Heavy-duty spherical roller bearings are combined with double-layer nylon labyrinth seals and outer rubber dust covers, helping isolate mineral dust, moisture and slurry from the bearing chamber and maintain smooth rotation during long-term operation.

Integrated Welding and Final Performance Verification

The pulley body and shaft connection use robotic fusion welding to improve structural consistency and reduce stress concentration. Before shipment, each Tail Pulley undergoes dynamic balance correction, static load fatigue testing, rubber lagging peel-strength testing and salt-spray simulation. Inspection records are retained for batch traceability and project quality verification.

Field Test Data & Industry Pain Point Comparison

Six-Month Continuous Field Tracking

YUFENG conducted six consecutive months of continuous field tracking in underground coal mines, open-pit iron ore quarries, coastal ore terminals and cement raw material conveying lines. The Tail Pulley was compared with ordinary thin-wall pulleys under similar heavy-load operating conditions. The test focused on structural stability, lagging integrity, bearing operation and maintenance frequency rather than laboratory parameters alone.

Structural Stability During Continuous Belt Tension

Ordinary thin-wall pulleys are more susceptible to shaft bending and cylinder deformation when exposed to repeated belt tension. The reinforced cylinder and forged shaft configuration of YUFENG product maintained stable geometry throughout the tracking period, helping keep belt contact consistent and reducing the risk of secondary belt deviation caused by pulley deformation.

Longer Lagging Retention Under Return-Side Conditions

High-temperature vulcanized rubber lagging forms a stronger bond with the pulley shell than basic adhesive bonding methods. During continuous field operation, the lagging remained firmly attached without obvious peeling, supporting stable belt contact while reducing the frequency of pulley refurbishment and replacement.

Reduced Tail-Section Maintenance Requirements

The six-month tracking records showed that conveyor lines equipped with YUFENG product experienced fewer tail-section interruptions and lower replacement demand than lines using ordinary thin-wall pulleys. The combined effect of reinforced construction, durable lagging and protected bearings helped reduce maintenance downtime by 70% and annual pulley replacement expenditure by 64% in the tested applications.

Real Industrial Project Application Cases

Inner Mongolia Open-Pit Coal Mine Tail Conveyor Upgrade

In an Inner Mongolia open-pit coal mine renovation project, the original tail section used ordinary thin-wall pulleys and experienced shaft deformation, lagging peeling and frequent maintenance after several months of operation. Following replacement with YUFENG product, the tail-section failure rate decreased substantially during six months of continuous operation. Monthly spare-parts and maintenance expenditure fell by 64%, while the pulley service cycle increased from less than six months to more than 14 months.

Coastal Iron Ore Unloading Terminal

At a European coastal iron ore terminal, YUFENG product was selected for conveyor systems operating under frequent rain, salt fog and abrasive mineral residue. The corrosion-resistant surface treatment and protected bearing configuration helped maintain stable pulley rotation and belt contact during extended outdoor operation, reducing the need for frequent tail-section component replacement.

Cement and Metallurgical Material Conveying Lines

YUFENG product is also used in cement clinker, metallurgical slag and mineral residue conveying systems where abrasive dust and fine material can accumulate around the tail section. The reinforced pulley body and wear-resistant lagging provide stable belt contact for continuous conveying, while the protected bearing arrangement helps maintain reliable rotation in dusty production environments.

Why Choose YUFENG Factory？

Built for the Conveyor Tail Section

YUFENG product is specifically designed for the return and tail section of belt conveyor systems, where the pulley must maintain stable belt contact while handling continuous belt tension and material residue. Its reinforced construction provides reliable support for medium- and heavy-duty conveying lines operating for extended periods.

Stable Belt Contact and Reversing Performance

The pulley surface is engineered to maintain consistent contact with the conveyor belt during continuous rotation. Available lagging patterns help increase friction and reduce belt slip, making the pulley suitable for conveyors handling coal, ore, aggregate, cement materials and other bulk products.

Configurations Matched to Different Conveyor Loads

YUFENG can configure the pulley according to belt width, operating tension, conveyor speed and material characteristics. Different cylinder dimensions, shaft sizes, lagging structures and bearing arrangements allow the Tail Pulley to be matched with both conventional fabric belts and heavy-duty steel cord conveyor systems.

Adapted to Demanding Return-End Environments

Tail sections can be exposed to dust, moisture, material residue and temperature changes. YUFENG provides suitable surface protection, lagging and bearing configurations for mining, ports, cement plants, metallurgy and aggregate processing applications, helping maintain stable operation under demanding site conditions.

Engineering Support for Replacement Projects

For conveyor upgrades and pulley replacement projects, YUFENG can review existing pulley dimensions and operating parameters before production. Customers can receive dimensional drawings and configuration recommendations to simplify replacement work and reduce compatibility problems during installation.

Frequently Asked Questions

Q1: What makes a Tail Pulley different from a Drive Pulley?

A1: It is positioned at the opposite end of the conveyor from the drive section and mainly guides the belt through its return path while maintaining proper belt contact and tension. A Drive Pulley primarily transfers motor torque to move the belt, so its traction and power-transmission requirements are different.

Q2: How should I select the correct product size?

A2: Selection should consider belt width, belt tensile strength, conveyor speed, pulley diameter, operating tension and material conditions. YUFENG can recommend suitable pulley dimensions and shaft configurations based on the customer's existing conveyor parameters.

Q3: Which lagging options are available for Tail Pulley?

A3: YUFENG offers smooth rubber, diamond-pattern and other anti-slip lagging options. Ceramic lagging can also be considered for wet or high-slip applications where higher traction is required. The suitable surface depends on belt type, moisture level and conveying conditions.
