Product Definition & Power Transmission Function

Core Power Transmission Component

YUFENG Drive Pulley is installed at the head section of belt conveyor systems and functions as the primary power transmission component. It transfers mechanical power from the motor and reducer to the conveyor belt, generating the traction required for continuous material transportation. Compared with ordinary support idlers, the product directly handles the belt tension and torque generated by the conveying system, making structural strength, surface traction and fatigue resistance critical performance factors.

Heavy-Duty Design for Continuous Conveying

YUFENG develops and manufactures heavy-duty drive pulleys for long-hour bulk material handling applications. The pulley structure combines integrated welding with stress-relief annealing to improve dimensional stability and reduce the risk of shell deformation during extended operation. This design is suitable for demanding conveyor systems transporting bulk materials under high-load conditions.

Stable Traction Under Difficult Conditions

The product can be configured for both fabric and steel cord conveyor belts. Its surface lagging options provide reliable friction between the pulley and belt, helping maintain stable power transmission under dusty, humid and muddy operating conditions while reducing belt slip and unnecessary traction loss.

Raw Material & Manufacturing Craft

Reinforced Pulley Shell

The pulley shell is manufactured from Q235 seamless carbon steel pipe with wall thicknesses from 6 mm to 16 mm according to the required load rating. Circumferential seams are processed using submerged arc automatic welding, followed by furnace stress-relief annealing to reduce residual welding stress and improve long-term structural stability.

Forged Transmission Shaft

The transmission shaft uses forged 45 medium carbon steel and undergoes rough turning, quenching and tempering, ultrasonic flaw detection, precision grinding and finish machining. This multi-stage process provides the shaft with the strength and dimensional accuracy required to withstand continuous torque, bending loads and full-load conveyor operation.

Customized Lagging Options

YUFENG offers hot-vulcanized integral rubber lagging and cold-bonded replaceable rubber lagging. Natural-synthetic blended rubber with Shore A 65–75 hardness is available in smooth, herringbone and diamond surface patterns. For extremely wet mining environments, ceramic lagging can also be customized to provide higher traction and improved resistance to slippage.

Heavy-Duty Bearing & Sealing System

Heavy-duty double-sealed spherical roller bearings are combined with a multi-channel labyrinth sealing structure to help protect the bearing chamber from coal dust, mineral powder and rainwater. This configuration supports reliable rotation and helps extend the lubrication and maintenance interval of the drive pulley.

Five-Stage Factory Inspection

Every YUFENG Drive Pulley undergoes key inspection procedures before shipment, including ultrasonic welding inspection, transmission shaft flaw detection, static balance calibration, rubber lagging peel-strength testing and full-load rotational aging testing. These controls help verify structural integrity, surface bonding quality and operational stability for demanding conveyor applications.

Field Test Data & Performance Comparison

Long-Term Heavy-Duty Operation Verification

YUFENG conducted 8-month continuous field tracking tests in open-pit coal mines and coastal port conveying projects, comparing YUFENG Drive Pulley with conventional market pulleys under the same heavy-load operating conditions. The test results verified significant improvements in traction stability, structural durability and maintenance performance.

Reliable Anti-Slip Performance

Under damp mineral powder conditions, YUFENG diamond rubber lagging product maintains a friction coefficient above 0.45, while ordinary smooth steel pulleys may drop below 0.2 and experience frequent belt slipping. The enhanced traction performance helps reduce conveying interruptions and improves overall production efficiency.

High Structural Stability Under Continuous Load

After 30,000 hours of full-load operation, the shaft deflection of YUFENG Drive Pulley remains controlled within 0.12 mm. Compared with thin-shell pulleys that are more prone to bending deformation, the reinforced shell and shaft structure effectively reduce belt tracking problems and uneven belt edge wear.

Extended Lagging Durability

The hot-vulcanized rubber lagging structure maintains excellent bonding strength and surface integrity after long-term mine operation, resisting peeling and cracking caused by repeated friction and heavy loading. This reduces replacement frequency and lowers maintenance costs compared with ordinary lagging solutions.

Reduced Maintenance Requirements

With heavy-duty sealing protection and optimized bearing configuration, YUFENG Drive Pulley requires only periodic lubrication and routine inspection under normal working conditions. The improved contamination protection design helps reduce bearing failures caused by dust, moisture and mineral particles.

Solving Common Conveyor Drive Problems

The optimized shell thickness, reinforced shaft design and multi-layer sealing system directly address major operating issues including belt slipping, pulley deformation, lagging damage and bearing contamination failures, providing more stable power transmission for heavy bulk conveying systems.

Real Industrial Project Application Cases

Southeast Asian Open-Pit Coal Mine Conveying Project

A medium-long distance fixed conveyor system transporting approximately 12,000 tons of raw coal per day adopted YUFENG herringbone lagging Drive Pulley. The operating environment involved high humidity, heavy coal dust and frequent large material impact.

Verified Long-Term Mining Performance

After 26 months of continuous operation, the pulley shell remained free from deformation, rubber lagging showed no abnormal peeling, and the bearing chambers maintained good cleanliness without dust penetration. According to customer operation records, belt slipping incidents were reduced from 8–12 times per month to less than once every two months, significantly reducing maintenance labor and spare parts costs.

European Coastal Port Bulk Handling System

A European port terminal installed YUFENG diamond bidirectional lagging Drive Pulley on reversible conveyor systems transporting iron ore and gravel. To adapt to frequent rain and salt fog exposure, the customized ceramic composite lagging configuration provided stable traction during continuous bidirectional conveying.

Continuous Port Operation Performance

Operational records showed that the pulley supported approximately 20 hours of daily running with stable traction performance throughout different seasons, helping maintain efficient loading and unloading operations without belt slipping interruptions.

Wide Industrial Application Range

Beyond mining and port applications, YUFENG product is widely used in metallurgy plants, cement raw material conveying systems, thermal power coal supply lines and aggregate transportation projects. It is suitable for handling coal, iron ore, limestone, gravel and mineral powder materials under heavy-duty conveying conditions.
