Suppress Belt Misalignment and Lift-Up for Stable Operation and Improved Maintainability

Conveyor mistracking and belt lift-off are suppressed, improving stable operation and maintainability.

Issues in Coal Conveying Lines at Power Plants

Belt lift-off at angle change points and forced suppression with wheels, leading to frequent belt damage and mistracking
Belt mistracking before the tail pulley, resulting in reduced conveying stability
Frequent conveyor stops for mistracking correction, causing lower work efficiency and safety

*These issues caused not only conveying troubles but also increased operational costs due to frequent shutdowns and maintenance.

Belt Lift-Off Prevention at Angle Change Points

GATE-TYPTE CARRIER IDLERs installed at angle change points, belt lift-off and the resulting mistracking are simultaneously suppressed. Unlike conventional methods that forcibly press the belt down with wheels, the integrated hold-down roller and guide roller design minimizes belt damage while ensuring stable belt travel.

Belt Mistracking Correction Before the Tail Pulley

A-TYPE HOLDDOWN RETURN IDLER (3 rollers type) installed before the tail pulley correct belt mistracking, preventing the mistracking belt from running onto the pulley. This improves belt centering and overall line balance.

Real-Time Adjustment for Safe and Efficient Operation

By introducing HANDLE-TYPE MANUAL

BELT-ALINING RETURN IDLER, adjustments that previously required stopping the conveyor can now be performed in real time during operation, significantly enhancing operator safety and work efficiency.

Prevent Belt Mistracking and Spillage for Stable Operation and Cleaner Worksite

Issues in Coal Conveying Lines at Steel Plants

Belt Mistracking Caused by Uneven Loading

Belt mistracking occurred due to uneven loading.
This led to material spillage and material loss.
Dust around the conveyor worsened, affecting the work environment.
Prolonged mistracking accelerated wear on belts and rollers, increasing equipment failure risk.

Spillage at the Chute Section

Spillage occurred through the gap between the skirt rubber and rollers.
Frequent cleaning was required.
Dust dispersion negatively affected the work environment.

Frequent Coal Adhesion on Belt

Coal frequently adheres to the belt underside due to material characteristics.
Detached coal falls (spillages）when passing over return rollers, accumulating below the conveyor.
Wet or fine coal increases adhesion, worsening the work environment and increasing cleaning workload.

Safety Risks During Cleaning

Detached coal may accumulate in areas with poor footing or near moving parts.
Cleaning in these locations poses safety hazards to operators.
