The conveyor belt is tensioned between two or more pulleys; one of which is the drive pulley, powered by the motor. As the motor rotates the drive pulley, it pulls the belt, conveying materials. Flat idler, trough idler, slider bed, and trough slider bed conveyors are belt conveyors.
Belt conveyors are different from roller chain conveyors, which use sprockets to drive heavy-duty roller chains down the frame.
Let’s look at belt conveyors: how they work, their components, and applications.
Conveyor belt systems are complex ensembles of electrical and mechanical components. Here’s how they work.
Motor and drive units generate the conveyor's power by converting electrical energy into mechanical energy. Energy is then sent to the conveyor's drive pulley.
Motors/drives are selected based on:
Speed: based on conveyor pulley diameter and power generation capability.
Drive force: factors in friction, incline angle, and load.
Duty cycle: runtime hours per day determine general versus heavy duty.
Environment: protection from moisture, dust, or extreme temperatures.
Motors and drives come in AC, DC, variable, and constant speeds. They may be external or embedded in the conveyor frame.
Pulleys receive power from the drive to move the belt. They are large cylinders that sit at the head and tail of the conveyor frame. The belt is tensioned between the pulleys. When the motorized pulleys are turned, friction causes the belt to move.
Different conveyor pulleys perform specific functions based on their location:
The head pulley (drive pulley) is the primary pulley that drives the conveyor. It has the largest diameter for maximal contact with the belt.
A tail pulley sits at the other end of the conveyor where materials are being loaded. The tail pulley maintains belt tracking and is sometimes wing-shaped to clear debris from the belt.
A take-up pulley (tension pulley) sits below the conveyor and adjusts the belt to compensate for belt wear and stretch. This prevents slippage and damage. Some common configurations include the horizontal take-up (good for use in limited space), gravity take-up (used with a counter-balanced pulley), and screw take-up (a simple mechanism that uses a threaded rod).
A bend pulley alters the belt’s direction. Bend pulleys feed the belt down to the take-up system.
A snub pulley can be placed on the other side of the head pulley to maximize traction and belt contact. Snub pulleys improve belt power and lift.
A conveyor belt forms the moving surface on which products travel. Conveyor belts come in different sizes, materials, and configurations based on specific application requirements. Here are the primary design considerations:
Belting material: belts can be made with rubber, PVC, fabric, vinyl, steel cord, and other materials.
Covers: heat, fire, oil, chemical, and abrasion-resistant additives and materials can be manufactured into the top and bottom covers for handling destructive materials and withstanding harsh environments.
Dimensions: conveyors are highly specialized. Belts must match the system and be rated for the conveyor’s pulley diameters.
Edge protection: side cover reinforcement prevents ply separation. Sidewalls can also be added to capture materials on steeply inclined conveyors.
Cleats: protrusions can be glued, fastened, or vulcanized to the belt surface to enhance material handling and secure items on inclines and declines.
Integral molding: belts can have features such as cleats molded directly into the cover for enhanced durability.
Industrial conveyor belts are chosen based on the materials and environment they will experience and their function within a conveyor system.
While the belt is tensioned and moved by pulleys, it also requires support to handle the weight of its load. Belt conveyors use two support systems: idlers and slider beds.
Idlers are unpowered cylinders that rotate as the belt runs over them. They effectively distribute weight and minimize belt friction. They can also clear material buildup and prevent belt mistracking.
Slider beds are flat metal sheets that sit beneath the belt. Slide bed conveyors are cheap to buy and easy to maintain. They have few moving parts, so they operate more quietly than other conveyors. They also generate significant friction with the belt so they are best for short distances and precision conveying.
The conveyor frame supports and connects the conveyor components. It also determines the path conveyed materials will take. Frames incorporate material shape, load weight, working environment, and accessory requirements into their design. Frame considerations include:
Drive placement: side or center drives.
Frame type: formed steel channel, aluminum extrusion, or custom.
Coating: powder coatings can prevent environmental damage.
Conveyor frames must withstand intense vibration, tension, and load impacts over years of operation.
Control systems operate the conveyor and synchronize conveyor systems. Here is what they control:
Speed: assembly lines require variable speed drives that can be precisely controlled for conveyor interactions with workers and robots.
Direction: some operations require back-and-forth conveyance.
Automation: controls integrate industrial equipment and conveyors into a coordinated system that operates automatically.
Monitoring: control systems connect with photoelectric sensors, proximity sensors, and scales to monitor operations and provide real-time feedback. Automation allows for control systems to make adjustments as needed.
Safety: e-stops, safety switches, and guard sensors are programmed to shut the conveyor down when activated.
Warehouse management systems: in logistics and sortation, control systems integrate with optical sensors, scales, and other equipment to sort, route, label, and monitor product throughput.
Controls facilitate the safe, smooth operation of conveyor systems.
Trough idler conveyors support the belt with angled idlers, which bend the belt into a U-shape. They are best for long-distance conveyance and the powdery or wet bulk materials handled in the mining industry.

Slider bed conveyors support the belt with a flat metal bed. They are best for shorter transfer functions, lightweight materials, precision conveyance, and noise-sensitive environments. Slider bed conveyors often use PVC or plastic belts to reduce friction with the bed.
