Understanding Belt Strength Ratings and Conveyor Requirements

Each belt is classified by its strength, which denotes the maximum pulling force it can withstand. In the United States, belt strength is measured in Pounds per Inch of Width (PIW), reflecting the tension it can handle. Elsewhere, belts are rated by their ultimate breaking strength in metric units such as newtons per millimeter (N/mm) or kilonewtons per meter (kN/m). This strength rating depends on the belt's carcass reinforcement and the type and number of materials in its fabric plies, or in the case of steel-cable belts, the size of the cables. Notably, the top and bottom covers of the belt contribute minimally to its strength or tension rating.

The belt's strength, whether carcass tension rating or ultimate breaking strength, signifies the force it can endure. Exceeding this capacity with heavier loads, tension from takeup weights, or increased incline could lead to serious issues, potentially causing the belt to break. A higher-rated tension necessitates careful consideration of the belt's compatibility with the conveyor structure and its rolling components.

Each conveyor structure requires a belt with a specific tension rating, determined by factors such as:

• Length of the structure
• Conveyor incline angle
• Desired capacity
• Belt width
• Drag and inertia of rolling components

You need a conveyor belt that is cost-effective, long-lasting, innovative, and of course, that gets the job done. The question is, what kind of belt can accomplish all these things for your particular application? To answer this, we first turn the questions to you.

Choosing the right belt for your conveyor system can be determined by three factors: Purpose, Temperature, and Strength.

MIPR starts by asking what kind of product are you conveying?

Your product&#;s properties will significantly impact selecting the belt that makes the best use of your time and money. If you&#;re conveying bacon, which is deliciously fatty but corrodes rubber over time, we will select a different belt than conveying lumber which might have high impact or friction.

What compound should we select to make the conveyor belt successful for your particular use?

• To decide on a material, we have to consider the operating temperature, the need for incline, the size of your head and tail pulley, and any other resistance factors related to your product.

• Let&#;s go back to our examples in the first question. To account for the fattiness of bacon, we need a highly oil-resistant material. We might choose Nitrile for this belt. In a conveying wood system, we may consider an SBR belt for its excellent wear protection.

• Similarly, a factory that freezes vegetables will have different needs than a bakery operation. A Cam-Grid metal mesh belt, for example, offers protection against both high and low temperatures.

• We will also think about whether your product is traveling up or down at an incline. In these situations, we may suggest a cleated or chevron belt to keep your products in place as they travel through the system.

• Knowing your head and tail pulley&#;s size will determine the maximum and minimum thickness of the belt needed.

There are many complex factors to consider when choosing your belting system. We&#;re here to make sure you get the optimum belt for your operation. MIPR offers hundreds of belts to choose from, ranging in size, weight, material, and style. Explore our many belt offerings at miprcorp.com
