Common Faults and Troubleshooting Methods for Belt Conveyors

ATHENS, Ala. - May 26, 2025 - PRLog -- Belt conveyors, as a core component of bulk material transport, are widely used in industries such as mining, ports, metallurgy, and chemicals. However, due to long-term operation or improper maintenance, belt conveyors are prone to several common faults.

Belt Deviation During Operation

Misalignment of Drive Pulley or Tensioning Pulley

Fault Manifestation:

The belt continuously deviates to one side during operation, reducing transport efficiency and potentially causing safety hazards.

Solution:

1. Adjust the position of the drive pulley's bearings to align it parallel to the conveyor belt.
2. If the belt drifts to the right, tighten the right tension screw; if it drifts to the left, tighten the left screw.

Misaligned Rollers or Uneven Belt Joints

Fault Manifestation:

The belt's deviation aligns with the roller axis deviation, causing unstable operation.

Solution:

1. Check the roller bracket position and recalibrate it to ensure perpendicular alignment with the conveyor's centerline.-https://zoomry-ind.com/Conveyor-Rollers/
2. For uneven belt joints, disassemble and reconnect the belt, ensuring the joint is straight.

Improper Loading Position or Frame Placement

Fault Manifestation:

Material piles up on one side of the belt, causing off-center operation.

Solution:

1. Ensure materials are loaded evenly at the center of the belt.
2. Adjust the conveyor frame to maintain a level position and avoid uneven stress.

Belt Slippage and Solutions

Insufficient Belt Tension

Fault Manifestation:

The belt cannot drive effectively during operation, leading to slippage or stalling.

Solution:

1. Adjust the tensioning device to increase the belt's tensile force.

Smooth Pulley Surface or Stiff Bearings

Fault Manifestation:

Insufficient friction between the pulley and the belt, causing slippage.

Solution:

1. Clean the pulley surface or apply a layer of adhesive material to enhance friction.
2. Dismantle the bearings, lubricate them, or replace damaged bearings.

Improper Pulley Bearing Installation

Fault Manifestation:

The pulley fails to rotate normally, affecting the belt's driving performance.

Solution:

1. Check the bearing installation position to ensure alignment with the pulley's centerline.

Roller Stoppage and Solutions

Belt Not in Contact with Rollers

Fault Manifestation:

The rollers fail to rotate, causing the belt to sag or deviate.

Solution:

1. Adjust the roller installation position to ensure proper contact between the belt and the rollers.
