Conveyor belts are not a new thing and have been in use for decades. They help transport materials, even abrasive ones, efficiently. Interestingly, different types of conveyor belts are available. Among these, mining conveyor belts are popular. This article covers important features for a mining conveyor belt system.
Although mining conveyor belts are widely used, people still have a limited understanding of them. That’s why they get confused when choosing a mining conveyor belt system. Therefore, learning the key features of a mining conveyor belt system is important. In this article, I will discuss various properties and features of mining conveyor belts. Let’s get started.
What is a Mining Conveyor Belt and What Makes it Unique?
Before I discuss features, let’s first understand the basics of mining conveyor belts.
Mining conveyor belts are heavy-duty and designed to withstand harsh use. These conveyor belts are used to transport abrasive materials. These include coal, ore, and minerals. Their belt is so strong and rugged that it can easily withstand abrasive materials. Additionally, these conveyor belts have a higher load capacity, which sets them apart.
In the past, trucks were commonly used at mining sites to transport mined materials off-site. Those trucks used to consume more fuel. Additionally, loading and unloading abrasive materials onto these trucks was difficult. That’s why mining companies shifted to conveyor belts. Remember, mining conveyor belts are not the same as conventional belts.
Instead, they are designed differently and made to withstand harsh loads and abrasive materials. The belts of this conveyor system are made with three layers. Manufacturers add steel wire braid reinforcement in the middle layers. These braids or reinforcements make these mining conveyor belts very durable and strong. As a result, they can easily transport abrasive materials.
Additionally, the frames of these conveyor belts are made from strong materials. These include stainless steel, aluminum, and so on. These make the belt systems very rugged and able to withstand harsh conditions without rusting. Other materials of both mining and regular conveyor belts are the same. These include rollers, pulleys, control systems, and so on.
Questi heavy-duty conveyor belts come with strong motors. However, these motors are energy-efficient, a significant advantage. So, a mining conveyor belt can transport materials for a long time with minimal electricity. Ruggedness and speed are some prominent properties of these mining conveyor belts.
Features for a Mining Conveyor Belt System
As I mentioned above, mining conveyor belts differ from conventional ones. Why? That’s because mining conveyor belts are made with specific properties in mind. This ensures these belts perform better in transporting abrasive materials. In the section below, I will discuss the properties and features of mining conveyor belts. Knowing these features is essential, especially if you’re going to buy a mining conveyor belt.
1- High Load Capacity & Tensile Strength
In mining operations, hundreds of tons of mined materials are exported outside the mining site. That’s why the mining conveyor belt must be able to withstand high loads. The higher load capacity ensures the belt performs efficiently even when loaded beyond its normal capacity. Additionally, mining conveyor belts generally have higher tensile strength. This is very useful, as it ensures belts remain in good condition despite being subjected to pulling forces. This prevents the mining belt from cracking unexpectedly when subjected to sudden forces or impact.
2- Easy Maintenance & Safety Features
Mining sites generally don’t have advanced workshops nearby, right? The mining conveyor belts are made very simple. They consist of simple components such as pulleys, rollers, and so on. Additionally, removing and replacing these components is generally easier and less confusing. Mechanics can easily disassemble them if they face any issues.
Additionally, mining belts are very safe due to their advanced safety features. These include an emergency stop button, a fire detection system, modern sensors, and more. These safety features ensure that mining conveyor belts detect issues first. If the issue is not resolved, they may stop before causing any hazardous issues for workers.
3- Wear & Abrasion Resistance (Durability)
The mining conveyor belts are typically very strong. They don’t wear out quickly despite transporting harsh or abrasive materials. The reason is that manufacturers use steel wire reinforcement in the middle layer of these belts. Regular conveyor belts are often cut or damaged when carrying harsh materials. Due to better construction, the mining conveyor belt remains in good condition. This means the mining conveyor belts are more durable than conventional conveyor belts.
4- Impact & Tear Resistance
All the mining conveyor belts are designed to resist both impacts and tears. Impact resistance refers to the ability to absorb sudden shocks. These conveyor belts have multi-layer constructions. Their middle reinforced layer plays a key role in making mining conveyor belts resistant to both impact and tears. In mining sites, falling rocks are common on the belts. That’s why manufacturers always make these belts resistant to sudden shocks. As a result, the mining conveyor absorbs the impact force.
5- Energy efficiency & Fast Speed
Mining conveyor belts must be energy-efficient and fast in operation. If they are slow or consume more power, they can make mining operations very costly. That’s why manufacturers use energy-efficient electric motors for these belts. These motors consume less energy but offer fast speed. Additionally, they also prefer low-resistance rollers and lightweight belts. This further improves the operational speed of mining conveyor belts. Remember, fast-speed conveyor belts help transport ore, coal, and other materials quickly. This can improve the productivity of the whole mining site.
6- Heat, Cold & Fire Resistance
Mining conveyor belts can get exposed to a wide range of temperatures (both low and high). Therefore, they are made to withstand both extreme temperatures. Additionally, they offer decent fire resistance, which is a significant advantage. Manufacturers add different components to make these belts. These compounds make the conveyor belts flexible.
Additionally, these compounds ensure that belts do not get stiff when exposed to low temperatures. This prevents cracking of conveyor belts. As a result, mining companies continue to use these conveyor belts in extreme conditions with ease.
7- Long Distancing Material Conveying Capacity & Incline
Miners dig deeper into the rocks to extract different minerals, coal, ores, and so on. These materials are then transported out through conveyor belts. Therefore, mining conveyor belts are powerful enough to transport materials over long distances. In fact, they can transport material over a kilometer.
During this transport, these belts maintain a consistent speed. As you know, mining sites generally have uneven and rough terrain. At some points, the conveyor belt may need to transport the material either upwards or downwards. Therefore, mining conveyor belts must be inclined. This ensures the effective transportation of the mined materials over slopes.
8- Oil, Chemical & Moisture Resistance
Mining sites have everything – oil, fuel, chemicals, and moisture. No one can control these aspects in mining operations. Oil leakage from vehicles, such as trucks, is one of the most common issues at these sites. That’s why mining conveyor belts must be resistant to oil, chemicals, and moisture. If not, the belts may swell when exposed to either oil or harsh chemicals. Additionally, consistent exposure to moisture can cause the belt to slip. A belt with no oil or chemical protection should not be used on mining sites.
9- Corrosion Resistance & Long Life
As you know, the body or frame of conveyor belts is made of metal. However, manufacturers generally use premium metals to make the frame or body of these mining conveyor belts. The best example of a corrosion-resistant material used in making frames is stainless steel. As a result, the mining conveyor belts become very strong and corrosion-resistant. Remember, this corrosion resistance makes the conveyor belts last longer. Even when exposed to chemicals, mining conveyor belts still offer a longer service life.
10- Automation & Auto Discharge System
Mining conveyor belts generally have excellent automation. This makes the working of these belt systems more efficient and automated. Remember, the level of automation of mining conveyor belts depends on their prices. High-priced mining conveyor belts are highly automated, and vice versa.
Some mining conveyor belts even come with programmable logic controllers. These features help control and monitor the working of these belts. Additionally, these conveyor belts also have an auto-discharge system. They will discharge the loaded material at a specific (designated) location automatically. There is no need for intensive labor to remove loaded material from the mining conveyor belts.
Conclusione
As discussed above, mining conveyor belts are very durable and robust. That’s because they are utilized in extreme conditions with harsh loads. If they are weaker, they will deteriorate quickly even during the transportation of materials. From the frame to components and belts, everything is designed for high durability.
That’s why the price of mining conveyor belts is higher than that of regular conveyor belts. There are certain features that you get in almost every mining conveyor belt. In this article, I have discussed the features and properties of mining conveyor belts. You must consider these features when purchasing a belt for mining purposes.
