When choosing a belt conveyor system, one of the most important decisions youll have to make is which belt it should be equipped with. In most cases its the only part of the conveyor thats actually in contact with your parts, product or packaging.
Here are eight important questions to ask when choosing a belt:
What is the coefficient of friction? Belt surfaces range from an extremely low coefficient of friction to a high coefficient of friction. Low friction belts are ideal for accumulation applications or side-entering or -exiting applications where product must slide while the belt continues to move. High friction belts are often found in incline applications up to 15° to ensure positive product movement simply through friction between the product and the belt.
What are the maximum and minimum temperatures? There are two temperatures you should be concerned with: ambient operating temperature and temporary part temperature. Each is important for the long-term function of the belt. Ambient temperatures that are too cold can lead to brittleness and cracking of the belt; temperatures that are too high could lead to belt stretch or delamination at the splice. Short-term part temperature specifications ensure hot parts dont damage the surface of the belt when theyre placed or dropped onto the conveyor.
What color is the belt? Color is most important in inspection applications, whether its automated with cameras or a visual inspection by an operator. Proper color contrast with the product can be vital for spotting defects or impurities. Blue is very common in food applications since its a color that rarely appears naturally in foods, making it easy to spot residue after cleaning.
Is the belt cut resistant? If your product has sharp edges, a cut resistant belt may be necessary to avoid cutting the surface of the belt. These belts typically include a hardened urethane or PVC top surface.
Should I use a sealed edge belt? To reduce particulates in cleanroom environments, a sealed edge belt is typically recommended. These encapsulate the cut edges of the belt to seal in the fibers of the carcass. Without a sealed edge, those fibers may be released as the belt flexes around the pulley.
Does the belt have release properties? In some applications, product may tend to stick to the belt, whether its a sticky confectionery product or glue from a packaging process. A silicone belt helps to ensure the product is released cleanly.
Do I need cleats? Cleated belts are common for applications where parts need to be pushed up an incline or restricted from sliding or rolling down a decline. Theyre also used to maintain product spacing, especially in applications where parts are fed manually by an operator. Cleats are placed at custom intervals based on the customers specifications and are available in a variety of heights for different products and applications.
Whats in stock? All these considerations mean nothing if finding the perfect belt would push the lead time past the date you need the conveyor. With hundreds of potential belt types, it would be impractical for conveyor manufacturers to stock every type. Most manufacturers stock a limited number (at QC Conveyors we stock seven types, which cover about 95% of our conveyor orders) and rely on the belt manufacturers to supply others as needed. This can double or triple the lead time for the conveyor, so its important to know which belts your conveyor manufacturer stocks, especially if you need a conveyor quickly. You may be able to compromise on one of the other requirements to help meet your lead time requirement.

Conveyor systems are the lifeline for many industrial bulk material handling operations and when your conveyor belt is not performing to your expectations anymore, it may be time to review your specifications and look into Fenner Dunlop belting options. When selecting a new belt for your conveyor system, it is important to think about your production goals and how a conveyor belt can help you achieve them. Before committing to a new conveyor belt, be sure to ask the following questions.
Knowing where a belt is made can give you an insight into its quality. For example, imported conveyor belts are often not produced in the same plant every time (even if the local supplier or distributor is the same). Some plants have high production standards and follow a quality management system, while others do not. As a result, consistency of the belt can vary greatly from purchase to purchase. In addition, even belts built in the US often contain finished fabric carcasses shipped from outside of North America, which can deteriorate in overseas shipments via changes in humidity and moisture conditions. Inconsistency in quality and performance can lead to costly downtime and loss of production security.
Our Answer: When you purchase a belt from Fenner Dunlop, we can tell you exactly where it was made because we manufacture our own belts in North America, which allows us to control every step of the vertically integrated production process. All of our fabric belting carcasses are engineered in our state-of-the-art weaving facility in Lavonia, Georgia. Production is then passed on to our conveyor belt manufacturing plants in Port Clinton, Ohio, Toledo, Ohio, and Bracebridge, Ontario. Specialized attention is given to each belting order to ensure that we produce the highest quality conveyor belts that will assist you in reducing operation costs, maximizing uptime and improving revenue.
If you are having issues with constant damage to your belt or are simply not seeing ideal end results, maybe the belt is not suited for your particular bulk material handling application. You wouldnt put a belt without an oil resistant cover on a system that handles grain or wood products and you wouldnt put a light duty belt on a system that could be more susceptible to puncture damage under a primary crusher. This may seem like common sense, but it is easy to feel overwhelmed when making the decision to purchase a new belt.
Our Answer: Fenner Dunlop is proud to serve a variety of markets and we design and manufacture the widest range of conveyor belts in the world. With sales, service, and technical personnel in conjunction with our world-class distribution network stationed throughout the Americas, we can visit your facility to learn more about your production goals and operational challenges.

There are several factors that can influence the upkeep of a conveyor belt, like the type of belt and what it is used for. To ensure maximum performance results from your conveyor belt, it is important to conduct regular assessments of the conveyor system and perform regular mechanical maintenance. Tramp material buildup and failing components can lead to a multitude of serious reliability issues.
