Overview of Modern Conveyor Types and Uses

Industrial conveyor systems encompass a wide range of designs, each tailored to address distinct operational needs; whether transferring bulky cartons in a warehouse environment or transporting fine powders within a food-manufacturing facility, you’ll find a conveyor solution customised for such applications.

Selecting the right system depends on factors such as the type of material being handled, the distance to be covered, and the configuration of your workspace. In the following sections, we delve into the essential elements that drive conveyor operations and examine the technological advances that have revolutionised these systems over the years.

Key Components Common to Conveyor Systems

Most conveyor equipment, regardless of its complexity, shares a few fundamental components. At the heart of many systems is a drive pulley or motor, which provides the power to move materials. This power is transferred to a surface, such as the familiar conveyor belts, which creates the motion needed for transport. The entire assembly is supported by a sturdy frame that holds everything in place.

One of the key benefits of using conveyor systems in manufacturing is the boost in operational efficiency. By automating the movement of goods, you reduce manual labour, increase throughput, and ensure a consistent flow in your production process. This automation is critical for maintaining a competitive edge.

Ultimately, these core components work together to ensure optimal performance. When the drive, surface, and frame are correctly matched to the application, the conveyor system provides a reliable and efficient method for material handling, minimising downtime and maximising productivity.

How Conveyor Technology Has Evolved

Conveyor technology has a surprisingly long history, with early forms like the Archimedes' screw dating back to ancient times. For centuries, most material transport relied on manual handling, which was slow, labour-intensive, and often unsafe. The Industrial Revolution marked a significant turning point, introducing mechanical systems that began automating these processes.

The real transformation has occurred more recently with the rise of widespread automation. Modern conveyor systems are no longer just simple moving belts. They are sophisticated, highly specialised machines integrated directly into production lines. This evolution has led to a wide variety of conveyor types, each optimised for different materials, speeds, and environments.

This specialisation means you must carefully consider how to choose the right conveyor for your specific application. The advanced options available today offer incredible efficiency but require a clear understanding of your operational needs, from the type of material being moved to the layout of your facility.

Belt Conveyors: Features and Industrial Uses

When you picture a conveyor, you are likely thinking of a belt conveyor. As arguably the most common type, it features a simple yet effective design: a continuous belt that rotates around two or more pulleys. One of the pulleys is powered, moving the belt and anything on it forward.

This versatility makes them a popular choice for countless applications, including assembly lines, packaging stations, and sorting centres. We will now look at some typical uses for these systems and compare them to other conveyor types.

Typical Applications for Belt Conveyors

Belt conveyor systems are incredibly versatile, making them suitable for a wide range of industries and tasks. Their ability to handle everything from small parts to bulk materials explains their widespread use. In industries such as food processing, specialised sanitary belts are used to maintain hygiene during product transport. This adaptability is one of their greatest strengths.

Belt conveyors differ from other conveyor types in their applications due to their flexibility. They can be configured in various ways to suit a plant's layout, covering long distances that would be inefficient for other systems. This makes them ideal for large warehouses and

manufacturing facilities.

Common applications include:

• Assembly lines: Moving products from one workstation to the next.

• Bulk material handling: Transporting materials like grain, sand, coal, and ore.

• Warehousing and distribution: Moving boxes and packages for sorting and shipping.

• Incline and decline transport: Moving items between different floors or elevations.

Roller Conveyors: Design, Types, and Uses

A roller conveyor moves items using a series of rollers mounted in a frame. These systems are a staple in warehouses, distribution centres, and production lines where boxes, totes, and pallets need to be transported. Their simple design makes them a cost-effective, reliable solution for many material-handling needs.

There are two main categories: gravity roller conveyors, which use gravity to move items, and powered roller conveyors, which use motors. Let’s explore the differences between these two and the applications where roller conveyors truly shine.

Where Roller Conveyors Excel in Material Handling

Roller conveyors are workhorses in many material handling processes, especially in environments focused on packaging, shipping, and order fulfilment. Their robust design allows them to handle heavier loads than many other types of conveyors, making them perfect for moving pallets, large boxes, and industrial containers. The rollers provide a low-friction surface, ensuring smooth movement.

These systems are also excellent for improving space utilisation. They can be installed as floor-level lines or integrated into multi-level picking modules in large distribution centres. This flexibility allows you to design efficient workflows that make the most of your available square footage.

Roller conveyors are particularly effective in:

• Shipping and receiving docks: For quick loading and unloading of trucks.

• Assembly lines: Transporting larger components between workstations.

• Warehousing: Moving goods from storage areas to packing stations.

  
  

Speciality Conveyors for Bulk and Granular Materials

While belt conveyors are often used for bulk material handling, some situations call for more specialised equipment. When you are working with fine powders, grains, or other granular materials, systems designed specifically for these products offer better containment and control.

Conveyors like screw and pneumatic systems provide enclosed transport, which is crucial for minimising dust and preventing product loss. These speciality conveyors are essential in industries like agriculture, food production, and chemical manufacturing.

Screw Conveyors: Basic Functionality and Advantages

A screw conveyor, also known as an auger, is one of the oldest and most reliable designs for moving bulk goods. The basic functionality is simple: a large, helical screw rotates inside a tube or trough, pushing the material forward. This mechanism provides a consistent, continuous flow, ideal for semi-solid and granular materials such as animal feed, wood chips, and food waste.

One of the main advantages of screw conveyors is their simple design. With few moving parts, they are relatively easy to maintain and clean. This simplicity makes them a cost-effective choice for many applications where material integrity is not the top priority.

However, it is important to match them to the right job. Their rotating action can sometimes cause breakage or compromise blends, and they are less efficient on steep inclines. For specific operational needs involving durable materials, screw conveyors offer a powerful and dependable solution.

Pneumatic and Vibratory Conveyors for Bulk Transport

For moving fine, dry powders, pneumatic conveyors are an excellent choice. These systems use air pressure or a vacuum to fluidise materials and move them through a completely sealed pipeline. This enclosed design is a major benefit, as it significantly reduces dust and prevents contamination, making it ideal for food products like sugar, flour, and starch.

Pneumatic conveying systems are highly flexible and can be routed around existing equipment, but this comes with trade-offs. They are not the most energy-efficient option and require regular filter maintenance. The high velocity can also damage fragile products.

When choosing a conveyor for bulk material handling, pneumatic systems are best suited for powders that need to be transported cleanly over complex routes.

These systems are a great fit for:

• Food products: Transporting ingredients like sugar, flour, and starch.

• Chemicals and minerals: Moving fine powders and sands in a contained environment.

• Plastics: Conveying pellets and powders in manufacturing facilities.

Chain, Slat, and Overhead Conveyor Types and Uses

For particularly heavy or awkward items, a chain conveyor is often the best solution. These systems use a continuous chain to pull products along a production line. The chain runs over sprockets and can be fitted with attachments to handle specific items, such as pallets, industrial containers, or large components.

This robust design makes them indispensable in industries with specific needs for durability and strength. We will explore the common industries that rely on chain conveyors and look at the unique benefits offered by other specialised systems.

Common Industries and Applications for Chain Conveyors

Chain conveyors are built for tough jobs. Their strength and durability make them a go-to solution in industries that handle heavy materials or operate in demanding environments.

One of the most common industries that uses chain conveyors is automotive manufacturing, where they are used to transport car parts, chassis, and even entire vehicles through assembly and painting facilities.

Their ability to handle bulky, oddly shaped items sets them apart from other conveyor types. While a belt conveyor might struggle with a heavy pallet, a chain conveyor is designed for exactly that kind of load. This makes them essential for meeting the operational requirements of heavy industry.

You will often find chain conveyors in:

• The automotive industry: Moving parts through paint and assembly lines.

• The furniture industry: Transporting large wooden components.

• Warehousing and logistics: Moving pallets and large grid boxes.

• The pharmaceutical sector: Handling industrial containers and equipment.

Unique Benefits of Slat and Overhead Conveyor Systems

Beyond common conveyors, other specialised systems offer unique benefits for specific challenges. For example, vertical conveyors such as bucket elevators are designed for maximum space utilisation. By moving bulk materials straight up, they solve elevation challenges without taking up significant floor space, a feat that is difficult for standard belt systems.

Another innovative solution is the tubular cable conveyor. These enclosed systems are perfect for food processing applications where hygiene and gentle handling are critical. The cable-and-disc design moves materials without causing damage and prevents any direct contact with the outside environment, keeping products like coffee, nuts, and breakfast cereals safe from contamination.

Unique benefits of these systems include:

• Vertical transport: Bucket elevators move materials upward, saving valuable floor space.

• Gentle handling: Cable conveyors protect delicate and fragile products from breakage.

• Improved hygiene: Enclosed designs keep materials contained and free from contaminants.
