Belts

Conveyor belts are on the front lines of your conveyor system. They come in scores of varieties, from lightweight to heavy duty, and in a range of surface materials and coverings. With such a vast selection, it’s important to find the right belt—and overall conveying system—for your business needs and industry requirements

A leader in conveyance automation solutions, Dorner offers standard lines and highly customized systems. We’re also one of the few companies of our kind with an in-house belting cell operation. This means we’re able to partner with leading suppliers to offer custom conveyor belts and conveying systems that perform and last. 

Why Dorner Conveyor Belts Stand Out

Dorner conveyor belts stand above the rest compared to the products of other conveyor belt suppliers for a variety of reasons. Our in-house team performs peerless operations including cutting, splicing, v-guiding, testing, and inspecting all of our customer’s conveyors. We also provide industry-leading belt tracking, tensioning methods, and speeds.

We make all of our vacuum conveyor belts in our facilities so we can guarantee optimal perforation pattern quality and part-holding ability. The Dorner team also handles quality assurance to ensure our vacuum conveyors and conveyor systems are reliable and effective, a process that makes us one of the top conveyor belt manufacturers in the world.

With our unique V-guiding techniques, we can achieve superior tracking and accurate product movement with our conveyors. Before the belt is manufactured, we complete V-guiding to improve accuracy and integrity with a seamless belt guide. Other companies in the market apply V-guide after splicing, resulting in lowered accuracy and a higher risk of potential failure points.

In addition to the unrivaled quality of Dorner conveyor belts, our lead times are among the fastest in the industry, ensuring your business’ production line can keep running smoothly.

We have established ourselves as one of the leading conveyor belt manufacturers in the USA and around the world, and the quality of our products consistently demonstrates our commitment to developing innovative, effective conveying solutions.

A Closer Look at Conveyor Belt Types

There are a few overarching categories of conveyor belt construction, including fabric conveyor belts, modular conveyor belts, and flexible chain conveyor belts.

Fabric Conveyor Belts

Flexible fabric belts feature several layers in their construction, including the cover material, strength layer, and pulley side material. They also allow for small pulley diameters, which simplifies product handling and integration tasks. 

Available in a range of materials and weights, fabric conveyor belts can be woven or nonwoven, and they are suitable for a number of applications of varying weight classes. You can utilize fabric belts in different industries, including automation, material handling, and some FDA food processing applications.

Modular Conveyor Belts

With a solid construction that prevents fraying, delamination, and joining, modular plastic conveyor belts are versatile and durable. Modular belts can be customized to suit different widths and lengths, and the open surface area is often ideal for applications like cooling and draining, which is especially useful for sanitary or cleanroom processes.

Because they are easy to clean, sanitize, maintain, and repair, modular belts are great options for applications in many industries, including manufacturing, pharmaceutical, medical, food, bakery, and more. Dorner offers a variety of types of modular conveyors from our 2200 and 3200 Modular Belt Conveyors series

Flexible Chains

Ideal for complex layouts and various environments, flexible chains (or table top chain, in some cases), allows the use of the entire belt width, granting exceptional product handling flexibility. With a knuckle that moves through the center of the conveyor track, flexible chains feature open belt sides, and these conveyors are suitable for a number of applications, including automation, secondary packaging, manufacturing, bottling, and more. You can find flexible conveyor chain options in our FlexMove line, as well as our AquaGard 7100 Series Conveyors.

How to Determine Which Conveyor Belt I Need

Many Dorner conveying solutions allow you to select the proper belting option for your specific needs. In addition to your intended general application use, such as processes you perform and products you manage, you’ll need to consider some other factors when determining which belt you need, such as:

Temperature

Do you need a conveyor belt that can withstand high temperatures? Are you in the market for a cold-use belt? Silicone is a versatile belt material that can endure extreme temperatures and environments, making it suitable for industries like cooking and baking. If you require high temperature conveyor belting, a silicone conveyor belt may be suitable; we are also happy to collaborate with you on a custom solution.

On the other end of the spectrum, polyethylene is well-suited for lower temperatures, making it suitable for pharmaceutical processes or frozen food conveyor belting. 

Abrasion Resistance

If you deal with items that can cause wear and tear on your belts, you should assess the abrasion resistance capacity of the belts you’re considering. Polyurethane and nitrile-butadiene rubber are highly rated for abrasion resistance.

When the products you handle have rough surfaces or edges, they can damage your belts if you choose an insufficient material. For example, the nature of the metalworking industry and other industries that might encounter sharp edges call for a durable belt that can withstand cuts, scrapes and punctures. 

Other Considerations

There are many more considerations to make when purchasing a conveyor belt solution, including:

  • Surface layer material
  • Friction level
  • Static conductive or anti-static
  • Chemical resistant
  • Abrasion- and cut-resistant
  • FDA approval
  • V-guided
  • Color preference

Digging Deeper into Conveyor Belt Construction

Conveyor belts have a lot of options, including surface material and texture, pitch, and hinge design.

Fabric Conveyor Belts

Fabric is a popular conveyor belt material for applications requiring precision, high speeds, or delicacy.

Materials

The previous section listed a few material examples for specific use cases. Here’s a more complete list of surface layer options you’ll find in Dorner systems:

  • Thermoplastic urethane: Typically white, blue green or black in color.
  • Polyester: Typically clear in color.
  • PVC: Typically white, black, green or grey in color.
  • Silicone: Typically white or grey in color.
  • Nylon: Typically clear in color.

Belt Surfaces

Your intended application will help define which surface design is best for you. Examples include:
  • Smooth
  • Waffle
  • Fleece
  • Groove
  • Grip
  • Wave
  • Orb
  • Quadrangular
  • Rough top
  • Longititandle groove

Modular Conveyor Belts

Of the conveyor belt material types, modular belts are the most useful for sanitary or food-safe applications.

Modular Belt Pitch

In modular belt conveyor systems, pitch is the distance between pins. Our 2200 Modular Belt End Drive offers a 0.33-inch micro pitch belt option as well as a 0.6-inch pitch metalworking belt.

Hinge Design

Modular belts come with open and closed hinge options. An open-hinge design is ideal in situations where sanitation is of the utmost importance, as this design makes it easier to spot residue or debris. Open hinge belts also make object removal and cleaning processes much easier.

On the other hand, closed-hinged belts have higher capacities for abrasion resistance and durability than open-hinge belts. 

Modular Belt Surfaces & Materials

Modular belts are available with a variety of surfaces, including flat top, flush grid, raised rib, and more.

Modular belt material options include:

  • Polypropylene: Typically white or gray in color with a medium hardness.
  • Polyethylene: Typically natural in color with a soft hardness.
  • Acetal: Typically white, brown, blue or dark gray in color with a very hard hardness.
  • Nylon: Typically tan or white in color with a very hard, coarse hardness.

Pin materials include:

  • Polypropylene: Higher temperature, medium abrasion.
  • Polyethylene: Low temperature, low abrasion.
  • Acetal: Medium temperature, high abrasion.
  • PBT/Nylon: High temperature and high abrasion. Avoid use with water and other fluids.

Whether it is moving pharmaceutical drugs for bottle filling or delivering fresh globs of cookie dough from prep area to oven, when you see a conveyor belt in action, this work appears almost effortless—magical, even. This brings up the question: How do conveyor belts work? What factors are considered in conveyor belt construction?

First, it’s important to consider that not all conveyor systems have belts. Roller conveyors are commonly used to accumulate items, while belt conveyors are designed to move items of varying size, such as parts or finished products.

Fundamentally, though, conveyor systems run similarly whether rolled, wheeled, or belted. They are generally motor-powered, positioned on a solid frame, and run in a loop to move items from point A to point B. Configuration, such as the frame shape or drive placement, is another aspect of conveyor belt construction.

A conveyor system’s specifications determine its capabilities, such as load capacity and flow rate. For example, the speed of a conveyor system ultimately defines speed capacities. Conveyor belts are rated by per minute, while roller conveyors are measured by linear velocity. This speed, regardless of how it is measured, is what gives conveyors such an advantage over human labor.

Keeping your employees adequately trained and informed reduces downtime and increases workplace safety. Whether as part of your installation or at a later date, our knowledgeable field service staff members are available to lead a variety of training programs for your team. Our conveyor system training services include group and one-on-one sessions that cover use, care and preventative maintenance. We cover topics such as system safety, mechanical troubleshooting, and parts and belt changing.

In addition to on-site conveyor belt training services, your team will have access to our extensive online library of guides, whitepapers, case studies and videos. Finally, the Dorner blog and newsletter often features how-to and other helpful content. 

Dorner offers a comprehensive preventative conveyor belt maintenance program, available in two tiers: labor or parts and labor.
