Conveyor belt pulleys consist of a wheel on an axle or shaft designed to support movement and redirect tension. By using conveyor pulleys, small forces can move large objects, making heavy tasks more manageable.

What Conveyor Pulleys Are Used For

In everyday life, you may have encountered a pulley system in various forms. Using exercise equipment, opening your garage door, or riding an elevator are a few examples of pulley systems that make tasks simpler and more convenient. In industrial settings, the scale of application is much larger.

Conveyor pulleys are commonly utilized in shipping and marine applications, as well as in industrial equipment and heavy machinery. Typically, multiple conveyor pulleys are used to enhance mechanical advantage, thereby reducing the force needed to lift or pull weights. However, using more pulleys can decrease system efficiency due to friction.

A specialized block and tackle system is often employed on sailing vessels and fishing boats, allowing operators to lift heavy loads with little force. For industrial purposes, there are several types of conveyor belt components:

• Timing belt - Features notched teeth that mesh with the corresponding belt’s teeth.
• Flat belt - A smooth belt without notches.
• Round belt - Employed to transmit rotational motion around an axle.
• V-belt - Contains an angled track that aligns with the matching belt.

How Do Conveyor Belts Work?

A conveyor system systematically carries and transports materials, typically in an industrial or controlled environment. Conveyor belts are a tried-and-true energy saver designed to increase efficiency. Let's take a look at how conveyor belts work and why they've stood the test of time.

How a Conveyor Belt Works

Conveyor belts operate using two motorized pulleys that loop over a long stretch of thick, durable material. When the motors in the pulleys run at the same speed and in the same direction, the belt moves between them.

If the objects being transported are particularly heavy or bulky, or if they are moving a long distance, rollers might be installed on the sides of the conveyor belt for added support.

Parts of the Conveyor Belt System

Though there are numerous types of conveyor systems, all share the primary function of transporting materials. Some products may require systems without belts, using only rollers or wheels for flexible movement. However, many conveyor systems utilize a frame equipped with a belt and possibly support rollers to efficiently carry materials.

Every conveyor system comprises three main components: the aluminum profile, the driving unit, and the extremity unit.

The aluminum profile forms the framework, belt, and supports. Generally powered by a motor, conveyor systems may also utilize gravity or manual force to operate. Motorized conveyor belts are ideal for industrial applications due to their reliability and efficiency. The driving unit includes the motor bracket, electrical drive, and counter bearings.

The extremity unit of the conveyor belt system includes pulleys and clamping straps. Depending on specific functions or variations, additional stands or lateral guides may be required, so it is crucial to consider your industry requirements when selecting these optional components. The parts of a new conveyor belt system may include:

• The frame: This is the system’s backbone, holding all the moving components together for safe operation.
• The belt: A long stretch of resilient material responsible for transporting items from one location to another.
• The conveyor belt support: Rollers assist the belt's path and maintain its movement, ensuring stability.
• The driving unit: Motors may operate with variable or constant speed-reduction gears to power the conveyor belt. An effective driving unit ensures smooth operation, reversing, and directional adjustments.
• The pulleys: Strategically placed pulleys govern the belt's movements, managing vital tasks such as driving, redirecting, turning, tensioning, and tracking the belt.
• The clamping straps: Used to secure fixtures in various machines.
• Add-on modules: These additional components reinforce the system; while rollers internally support the belt, external stands and lateral guides support the framework.

Conveyor belts can be manufactured from several materials, including rubber, metal, leather, fabric, and plastic. It is essential to take into account the operating conditions when selecting appropriate materials that provide suitable thickness and strength.

The primary purpose of a conveyor belt is to transport items efficiently from Point A to Point B with minimal effort. The speed, direction, curvature, and size of the conveyor belt can vary based on user requirements. In certain industries, a conveyor belt carries products through manufacturing or packaging processes and back out again.

Conveyor belting generally falls under two categories: lightweight and heavyweight.

Lightweight belting is designed to cater to various material handling needs across diverse industries. This type of belting system maintains a working tension of under 160 pounds per inch of width. The primary types of lightweight conveyor belts include:

• Solid plastic
• Non-woven
• Thermoplastic covered
• Lightweight rubber

Prominent industries using lightweight belting comprise:

• Food processing
• Unit package handling
• Pharmaceutical
• Paper goods

For tougher applications, use heavyweight conveyor belting that maintains a tension of at least 160 pounds per inch of width. Heavy-duty belting systems are essential for applications necessitating continuous movement of bulky, heavy materials. These belts are often coated with PTFE to endure high temperatures.

Top industries utilizing heavyweight belting include:

• Mining
• Manufacturing
• Waste/recycling
• High-temperature food processing

Conveyor Belt Uses and Applications

The diverse lightweight and heavyweight belting applications highlight the versatility across various industries and settings. Regardless of the type, conveyor belt systems significantly enhance efficiency, productivity, and labor management.

Conveyor Belt Uses

A conveyor system serves numerous purposes, such as:

• Rapidly and reliably transporting substantial amounts of material
• Stacking materials at the transportation line's end
• Streamlining transitions from Point A to Point B
• Transporting products vertically or horizontally with a high degree of flexibility

The benefits of implementing a conveyor belt system encompass:

• Reduced labor costs while significantly improving productivity and time efficiency
• Enhanced worker safety by minimizing strain from lifting heavy loads
• Protection of products from potential damage during transportation
• Effortless transfer of goods onto alternative routes
• Simple maintenance for this durable, long-lasting system

Conveyor Belt Applications

Conveyor systems are extensively employed across numerous industries, including aviation, mining, manufacturing, pharmaceuticals, food processing, and beyond.

Airports depend on conveyor belts for efficient processing, sorting, loading, and unloading of passenger luggage. Baggage carousels exemplify the practical use of industrial conveyor belts experienced by most individuals, seamlessly moving luggage from secure loading areas to terminals.

Within the pharmaceutical sector, conveyor belt systems facilitate the transportation of cardboard boxes or pallets filled with medical supplies throughout the packaging and distribution processes. In manufacturing and mining, vast quantities of materials traverse tunnels, roads, and steep slopes on conveyor belts, requiring durable materials and effective support rollers.

In food processing, products are handled throughout their lifecycle on conveyor belts. Items can undergo numerous processes—spreading, stamping, rolling, glazing, frying, slicing, and powdering—while moving on the belt. This implementation dramatically reduces manual labor that would otherwise be spent transferring each food item through every stage of production. Conveyor belts allow high-speed, high-volume transport while ensuring consistent quality.

Each industry has specific requirements dictating the type of conveyor belt utilized. Conveyor belts are essential from shipyards and power plants to bakeries and ice cream manufacturers, revered for their simplicity and reliability.
