6 Core Categories of Belt Conveyor Parts

A complete belt conveyor system relies on coordinated operation of multiple belt conveyor parts. Each component undertakes independent structural and functional responsibilities, and minor mismatches will trigger overall system failures. In industrial bulk material handling, standardized part configuration is the core premise of high-efficiency and low-consumption operation.

Conveyor Belt: The Core Carrying Component

The conveyor belt is the most critical and consumable belt conveyor part, responsible for direct material bearing and linear transportation. Its material, thickness, and structural layer design determine load capacity, wear resistance, and service life.

Main Belt Types & Core Properties

Ordinary Rubber Belt

Adopts multi-layer canvas core with rubber covering on both sides, featuring moderate tensile strength and cost performance. Suitable for ordinary bulk materials such as grain, sand, and gravel under normal temperature conditions. It supports long-distance horizontal and low-inclination conveying, with stable daily operation and low replacement cost.

Heavy-Duty Anti-Tear Rubber Belt

Equipped with steel wire rope core or reinforced fiber layer, it greatly improves tensile resistance and anti-tear performance. It can withstand sharp material impact and heavy load pressure, suitable for high-intensity working conditions such as mining, cement plants, and quarry transportation.

PVC/PU Light-Duty Belt

Lightweight and environmentally friendly, with smooth surface and no material adhesion. Food-grade PU materials meet sanitary production standards, widely used in food processing, electronic assembly, and pharmaceutical conveying lines. It features low noise, oil resistance, and easy cleaning.

Belt Parameter Performance Comparison

For industrial long-term operation, Haihui recommends matching belt performance with material abrasiveness and working temperature to avoid frequent replacement and reduce overall operational costs.

Conveyor Rollers & Idlers: Support & Stabilization Parts

Rollers and idlers are the most numerous basic belt conveyor parts, undertaking the dual functions of supporting the belt and materials and reducing operating friction. Their operating flexibility directly affects belt stability and energy consumption.

Main Roller Classification & Functions

Flat Support Roller

Single cylindrical structure, mainly used for flat belt conveying lines. It provides uniform horizontal support, ensures smooth belt operation, and is suitable for packaged goods and small-batch bulk material transportation. Features simple structure, low failure rate, and convenient maintenance.

Trough Roller Group

Composed of 3 or 5 combined rollers, forming a U-shaped trough structure. It gathers bulk materials centrally, effectively preventing material spillage, and improves single-line conveying capacity by 30%–50%. It is the core matching part for heavy-duty trough belt conveyors.

Impact Roller

Adopts rubber buffer structure, installed at the material feeding point. It buffers the impact force generated by material falling, protects the belt from piercing and abrasion, and greatly extends belt service life. It is an essential wear-resistant part for high-drop feeding scenarios.

Return Roller

Installed at the bottom return section of the belt, supporting the empty belt operation. It keeps the belt running flat and avoids sagging and deviation caused by excessive belt gravity.

Core Roller Performance Standards

Qualified industrial rollers adopt precision steel pipe processing, with strict roundness tolerance within ±0.1mm. The internal bearing is sealed and dust-proof, ensuring flexible rotation after 20,000+ hours of continuous operation. Haihui optimizes roller surface anti-rust treatment and bearing sealing structure, adapting to dusty and humid industrial environments.

Drive & Driven Pulleys: Power Transmission Parts

Pulleys are the key power transmission belt conveyor parts, divided into drive pulleys and driven pulleys. They convert motor power into belt circulating traction to realize continuous material conveying.

Drive Pulley

Connected with the drive motor and reducer, it is the power source of the entire conveyor system. The surface is treated with rubber coating or anti-slip texture to increase friction with the belt, preventing slipping during heavy-load operation. High-power pulleys adopt thickened steel plate welding, with strong pressure resistance and stable torque output.

Driven Pulley & Bend Pulley

The driven pulley follows the belt for passive operation, cooperating with the drive pulley to form a closed circulation loop. The bend pulley is used for belt direction conversion, adapting to complex line layout and turning conveying needs.

Pulley Matching Key Points

Pulley diameter must match belt thickness and tensile strength; too small a diameter will cause excessive belt bending and accelerated aging. Industrial standards show that standardized pulley matching can reduce belt fatigue wear by more than 35%.

Drive System Assembly: Power Support Parts

The drive system is the power core of belt conveyor parts, composed of motor, reducer, coupling, and brake device. It determines the conveying speed, load capacity, and operation safety of the equipment.

Motor & Reducer

The motor provides basic power, and the reducer adjusts torque and speed to match heavy-load conveying demands. Low-speed and high-torque configuration ensures stable start-up and no stall under full-load conditions.

Brake & Backstop Device

The brake device realizes emergency shutdown and fixed-point stop; the backstop device effectively prevents material backflow and belt sliding of inclined conveyors, eliminating safety hazards caused by power failure and sudden shutdown.

Tensioning & Correction Parts: Stability Adjustment Components

Tensioning and correction parts are auxiliary functional belt conveyor parts, used to adjust belt tension and correct running deviation, ensuring long-term stable operation of the system.

Tensioning Device

Divided into screw tensioning, heavy hammer tensioning, and electric tensioning. It compensates belt elongation caused by long-term operation, maintains constant belt tightness, and avoids slipping and deviation caused by insufficient tension.

Deviation Correction Device

Automatic and manual correction structures adjust roller and pulley angles in real time, correcting belt deviation during operation. It reduces belt edge wear and material scattering, greatly lowering failure rates.

Cleaning & Sealing Accessories: Anti-Wear Auxiliary Parts

Cleaning and sealing accessories are easily overlooked but essential belt conveyor parts, effectively reducing component wear and environmental pollution.

Belt Cleaner

Installed at the head and tail of the conveyor, including primary and secondary scrapers. It cleans residual materials on the belt surface to prevent hard particles from entering the roller and pulley gap, avoiding equipment jamming and belt abrasion.

Skirt Board & Sealing Strip

Installed on both sides of the feeding section, sealing gaps between the belt and the frame. It prevents material spillage and dust leakage, meeting environmental protection production standards while reducing material waste.
