Why Does a Heat-Resistant Conveyor Belt Outlive a Regular Belt in Mining?

 

Hot lime, coke, fly ash, and others are some of the materials that are regularly conveyed in mining.

Do you know what they have in common? Their temperature.

These high-temperature materials are enough to make your regular conveyor belt age rapidly or break down suddenly.

In this case, what can you do? You have to choose a conveyor belt that can outlive such regular belts with its properties and durability. You should go for a heat resistant conveyor belt. Why? Check below!

Heat Resistant Conveyor Belt: 6 Reasons Why It Outlives a Regular Belt in Mining

Composition

A heat-resistant conveyor belt is made of synthetic polymers or rubber compounds having high temperature resistance. These compounds are formulated to remain unaffected by exposure to extremely high temperatures.

A heatguard conveyor belt can endure temperatures up to 125 degrees to 150 degrees for lumps. Besides, it can endure temperatures from 100 degrees to 125 degrees for fines.

Flexibility

Being made of thermally stable compounds or polymers, a heat resistant conveyor belt has adequate flexibility. There are other plastizers as well as processing additives that ensure its flexibility.

Hence, unlike a regular rubber belt, it does not swell. Besides, the heat resistant conveyor belt has adequate thickness. This thickness ensures flexibility and remains durable while handling materials at high temperatures.

Adhesion

The heat resistant conveyor belt has excellent bonding strength. As a result, it ensures that there is no separation from the cores, covers, or reinforcement. Unlike other rubber belt types, this conveyor belt can consistently perform under high stress. Due to better bonding strength, it does not breakdown and cause material spillage.

Wear-resistance

The heat resistant conveyor belt has resistance against abrasion. Materials such as coal, foundry sand, and others are abrasive in nature. Thus, it can scrape the surfaces of a regular belt and cause cracks, fading of color, and you can see different signs of damage.

This will hamper the condition of your belt and reduce its lifespan. Unlike other rubber belt types, this conveyor belt does not readily wear or tear while handling abrasive materials.

Slow Aging

A regular conveyor rubber belt ages rapidly with exposure to high temperatures. It starts to lose its color and hampers the overall properties. Meanwhile, a heat resistant conveyor belt has slow aging. It does not deform, fade, or damage in high temperatures of the industries.

Mechanical Strength

The heat resistant conveyor belt has superior physical properties. Its minimum value of tensile strength is 15 MPa, and elongation at break is 450%. As a result, unlike a regular rubber belt, it can endure physical stress without breaking down.

he heat resistant conveyor belt has a higher load bearing capacity. Hence, the heatguard conveyor belt is capable of transporting heavy materials from one place to another.

To sum up,

A heat resistant conveyor belt has suitable resistance against high temperatures, abrasion, and others. It maintains its flexibility and does not rapidly age in high temperatures.

In addition, unlike a regular rubber belt, it has high mechanical strength. Owing to its properties, the conveyor belt heat resistant and has high durability and offers a long service life.

Here are some FAQs you might be interested in!

1. What are the other types of conveyor belts other than an HR Grade conveyor belt?

Ans: The other types of conveyor belts with respect to the type of materials they are handling. These include oil-resistant, abrasion-resistant, fire-resistant, chemical-resistant, and others. However, there are other types with respect to the load capacity. These include conveyor belts for light, medium, and heavy weights.

2. How can you reduce material spillage from a high temperature conveyor belt?

Ans: You can use skirtboard rubber to seal the edges of the high-temperature conveyor belts. This will help you keep the materials intact. Besides, you also have to ensure that you regulate its speed. You also have to make sure that the conveyor belt has adequate tensioning and proper alignment to avoid slippage that can cause material spillage.

3. How is using high temperature conveyor belts better than manual material handling?

Ans: These conveyor belts can carry high temperature materials. On the other hand, manual handling can be risky. Any loss of balance can cause severe injuries after the high temperature materials fall. The belts automate the material handling process. Unlike manual material handling, it does not consume much time. As a result, this increases the overall efficiency of the industrial operations and decreases downtime costs.
