Belt Conveyor Belt Conveyor | XingQing Machinery

Product Overview

The Belt Conveyor is a continuous conveying equipment that uses the conveyor belt as both the traction and load-carrying component. The drive pulley drives the belt in cyclic motion through friction, and materials placed on the belt move with it, achieving continuous conveying from loading point to discharge point. The TB series is a general-purpose fixed Belt Conveyor with large load capacity and long conveying distance (single unit up to 240m, multiple units in series further). The full series has 7 models (TB-500 to TB-1600), belt width 500-1600mm, belt speed 0.8-3.15 m/s, capacity 40-2300 t/h, incline 0-20°. Widely used for horizontal or inclined conveying of lump, granular and powder bulk materials in mining, metallurgy, coal, port, building materials, power and other industries, and can also be used for piece goods conveying. Simple structure, standardized components, easy maintenance — the most widely used type in bulk material conveying.

Working Principle

Friction Drive

The motor drives the head pulley (drive pulley) through a gearbox. The belt wraps around the drive pulley with a certain pre-tension, and relies on the friction between the pulley and belt to drive the belt in cyclic motion. The tail pulley (bend pulley) is used to change the belt running direction, forming a closed loop.

Idler Support

Upper idlers (trough idlers) support the belt in a trough shape (usually 3 rollers forming 30°-45° trough angle), increasing the load cross-section and preventing material spillage. Lower idlers (flat idlers) support the return section belt. Idler spacing is typically 1-1.5m (carrying section) and 2-3m (return section).

Tensioning and Tracking

The screw take-up device (or gravity take-up) adjusts belt pre-tension to ensure the drive pulley does not slip. Self-aligning idlers and guide rollers automatically correct belt misalignment to keep the belt centered.

Conveying Process

Tail Loading → Trough Idler Support → Drive Drum Friction Drive → Belt Circulation → Head Discharge → Return Section via Bend Pulley

Product Features

High Capacity and Efficiency

The TB-1600 can reach a single-unit capacity of 2300 t/h, far exceeding other conveying equipment types, suitable for large-scale continuous conveying.

Long Conveying Distance

Single unit up to 240m, multiple units in series up to several kilometers, suitable for long-distance material transfer in mines.

Smooth and Reliable Operation

Idlers evenly support the belt for smooth operation with low impact, low failure rate, suitable for 24-hour continuous operation.

Wide Incline Range

Standard incline range 0-20°, both upward and downward conveying possible. Chevron belt can increase incline to 25°.

Standardized Components

Key components like belt, idlers, pulleys, and gearbox follow national standard dimensions for easy procurement and replacement.

Low Maintenance Cost

Daily maintenance only requires lubricating idler bearings and checking belt wear and tension. No complex wearing parts.

Application Fields

Mine Ore Conveying

Primary conveying of ROM ore from mining face to crushing station. Large-width TB series models (TB-1200~TB-1600) meet high-volume conveying needs, replacing mine trucks to reduce costs.

Plant Material Transfer

Material transfer between crushing, grinding, screening, and beneficiation stages. Belt conveyors connect process equipment to form continuous production lines. TB-500~TB-1000 are commonly used in processing plants.

Port Bulk Loading

Conveying and ship loading of iron ore, coal, grain and other bulk cargo from stockyard to wharf. Long-distance high-capacity belt conveyors are core port bulk logistics equipment. TB-1200 and above commonly used.

Coal Yard Transfer

Stockpiling and transfer at coal mines, washing plants, and power plants. Belt conveyors with stacker-reclaimers enable automated yard management. TB-800~TB-1400 are mainstream in coal industry.

Aggregate Conveying

Aggregate conveying between stages in crushing plants, including after primary crushing, secondary crushing, and screening. TB-500~TB-1000 for small-medium lines. TB-1200+ for large mines.

Power Plant Coal Handling

Fuel coal conveying from coal yard to boiler bunker in thermal power plants. Belt conveyors must meet continuous, safe, dust-proof requirements. TB-650~TB-1200 commonly used.

Selection Advice

Belt width determines capacity: TB-500 (40-230 t/h) to TB-1600 (500-2300 t/h). Select based on peak capacity with 20% margin.
Belt speed and material matching: Fine materials (coal powder, cement) can use high speed ≥2.5 m/s; large lump materials (ore, coal) recommend low speed ≤1.6 m/s.
Incline limitation: Standard belt incline ≤18°. For >18°, use chevron/corrugated sidewall belt or tubular belt conveyor.
Length and power calculation: Longer conveyors need more power. For heavy long-distance, use head+tail dual drive or multi-point intermediate drive.
Belt selection: NN nylon core for normal bulk materials; EP polyester or steel cord for large impact materials.
Site conditions: Rain covers and wind protection for outdoor long-distance; cold-resistant belt for severe cold regions; heat-resistant belt for hot materials (>80°C).
