What is a Roller Conveyor?
A roller conveyor is a material handling system that transports goods from one point to another using a series of cylindrical rollers mounted on a frame. The rollers are typically placed at equal intervals along the conveyor’s length, allowing items to move smoothly across the surface. Depending on the design, roller conveyors can be powered or gravity-operated.
Types of Roller Conveyors
1. Gravity Roller Conveyor
Gravity roller conveyor systems use gravity force to move items. They are often used in workplace applications where goods must be moved down a slope. A gravity roller conveyor requires no external power source, as the movement of the goods relies solely on the effect of gravity on weighted items. They are suitable for transporting goods short distances.
2. Powered Roller Conveyor
Each roller is powered by a motor, belt, or chain, allowing for the controlled movement of items from one place to another. A powered roller conveyor is suitable for more complex applications requiring precise control over speed and direction. This roller conveyor type can handle heavier loads travelling longer distances and can be integrated easily with automated systems.
Key Features of Roller Conveyors
- Versatility: Roller conveyors can handle various items, including boxes, pallets, and trays, making them suitable for many industries.
- Scalability: They can be configured in various lengths and widths, and additional features like curves and junctions can be added to enhance their material handling abilities.
- Durability: Roller conveyors are often made from robust materials like steel, and they are built to withstand heavy loads and harsh conditions.
What is a Belt Conveyor?
A belt conveyor system is a type of material handling equipment that uses a continuous belt to transport goods or materials from one location to another. The belt, typically made of rubber, fabric, or metal, is looped around two or more pulleys. One of these pulleys is usually powered by a motor, causing the belt to move, and the other pulleys, known as idlers, help to support the belt and maintain tension.
Types of Belt Conveyors
1. Flat Belt Conveyor
The most common type of belt conveyor system uses a flat belt to transport items over a flat surface. Flat belt conveyors are suitable for light to medium loads across assembly lines for packaging purposes or the transportation of goods.
2. Inclined/Declined Belt Conveyor
This type of conveyor belt is designed to move goods between different heights, meaning it can be set at an incline or decline where items need to be transported from one level to another. It can withstand various loads and is useful in warehouses and factories with multiple floors.

Roller vs. Belt Conveyor Uses
Choosing between a roller conveyor system and a belt conveyor system depends on your application’s specific needs, including the type of materials being handled, the required speed, the environment, and the level of control needed over the movement of items.
When Should I Use a Roller Conveyor?
1. Accumulation Needs
Roller conveyors, mainly accumulation conveyors, are suitable when items need to be queued up or accumulated at specific points along the conveyor without goods ever coming into contact with each other. This is common in packaging, sorting, and assembly processes.
2. Transportation of Flat and Sturdy Items
Roller conveyors are ideal for transporting items with a flat and rigid bottom, such as boxes, crates, and pallets. The items must be big and stable enough to move smoothly over the rollers without falling between each roller.
3. Heavy Loads
Roller conveyors are more suitable for moving heavy or bulky items, such as machinery parts, steel containers, or large pallets, because they can support substantial weights.
4. Human Ease of Interaction
Roller conveyors are more accessible for operators to manage. Due to a lower coefficient of friction than a conveyor belt system, they can swiftly push, pull, rotate, or remove products.
When Should I Use a Belt Conveyor System?
1. Items with Irregular or Small Bottoms
Belt conveyors are ideal for transporting items with irregular, soft, or small bottoms that wouldn’t move well on rollers, such as bags, packages, loose items, or fragile goods.
2. Steady & Controlled Movement
When items need to be transported at a constant speed without any gaps between them, a belt conveyor provides a continuous, smooth surface that ensures steady movement. This is particularly important in assembly lines and food processing.
3. Transporting Goods over Inclines and Declines
Belt conveyors are better suited for moving items up or down inclines. The continuous surface prevents items from slipping, especially when equipped with cleats or other gripping features.
4. Long Distance Transportation
Belt conveyors are more efficient for transporting materials over longer distances, particularly when a continuous, uninterrupted flow of materials is needed.

Roller Conveyor vs. Belt Conveyor FAQs
Yes, both systems can be integrated within the same facility. For example, a belt conveyor might transport items to a certain point, and then a roller conveyor can take over for sorting or accumulation.
How do maintenance requirements compare between the two conveyor systems?
Roller conveyors generally require less maintenance than belt conveyors, especially in rugged environments. Belt conveyors, however, need regular inspection for belt wear, tensioning, and cleaning, particularly in applications involving food or bulk materials.
Which conveyor system is better for high-speed operations?
Belt conveyors are typically better for high-speed operations because they provide a continuous surface that can move items quickly and steadily. Roller conveyors are more suitable for slower speeds, especially when accumulation is needed.
Can either conveyor system be customised for specific needs?
Both systems are highly customisable. Roller conveyors can be adapted with curves, merges, and different types of rollers, while belt conveyors can be customised with various belt materials, cleats, and sidewalls to handle specific materials or operating conditions.
