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.

FORWARD-TILTED CARRIER IDLER with TROIS GUIDE ROLLER

Corrects belt mistracking caused by thrust, preventing belt deviation and material spillage
Reduces material loss, extends equipment life, and stabilizes conveying operation

IMPACT SLIDE

Eliminates gaps between skirt rubber and rollers, reducing dust dispersion
Reduces belt load and cleaning workload, improving workplace safety and efficiency

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

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

Issues in Coal Conveying Lines at Mining Sites

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.
