winches, bearings, couplings, gearboxes, motors, fluid couplings, and scrapers work in unison to transport materials from Point A to Point B.

One of the more often overlooked parts of a conveyor setup is none other than the belt itself. This pivotal component helps support and transport the product safely to its intended destination.

Read on to learn more about the various types of conveyor belts and the deciding factors you should consider when selecting one for your conveyor system.

WHAT IS A MINING CONVEYOR BELT?

A mining conveyor belt is one of the most essential components of a conveyor system. It transports ore and other materials from the mining site to processing facilities or loading areas. 

Conveyor belts are powered by a motor that runs off electricity or other power sources. 

Depending on the application and several other considerations, the composition of the belt could include a plastic or rubber compound, fabric materials, and steel cables. It&#;s supported by rollers that allow it to safely and efficiently move ore and other materials at a predetermined speed. 

CONVEYOR BELT COMPOSITION

Conventional conveyor belts are comprised of three layers:

• The top layer, or cover, which is what the product rests on during transportation. 
• The middle layer, also known as the carcass, helps support the belt. The carcass tends to be made of either metal or woven fabric. 
• Finally, there&#;s the bottom cover to complete the belt makeup.

WHAT ARE THE DIFFERENT TYPES OF CONVEYOR BELTS?

It&#;s critical to choose the right type of conveyor belt to ensure safe and reliable operation. Using the wrong belt can lead to catastrophic consequences and unplanned downtime.

These are the different types of conveyor belts available:

• Multi-ply&#;Consists of various layers of fabric separated by rubber, which helps deaden impact. Tend to be longer-lasting and are used for underground applications. 
• Straight-warp&#;Ideal for tunneling applications, they&#;re most often used in rock quarries and rock crushers. Impact and tear resistance are the two premiere attributes, which feature yarns and polyamide on both sides. A straight-warp belt can achieve higher troughability at narrower belt widths and higher PIW ratings.
• Steel-cord&#;Steel cables running the entire length of the belt anchor this type of conveyor belt, which is used for underground applications.
• Solid woven belts&#;These are more popular in Europe and Asia and not used often in the U.S.
• Heat-resistant&#;Designed to withstand high temperatures.

CONSIDERATIONS FOR CHOOSING A MINING CONVEYOR BELT

If you&#;re shopping for a mining conveyor belt, you should first decide your tensile strength requirement, cover thickness, and cover type depending on the material being transported and loaded. Also of particular importance is the operating environment in which the conveyor transports material.   

Conveyors that move packaging or light materials in temperature-controlled warehouses won&#;t have the same demands as those transporting heavy products underground in mines and quarries.

This is why the application and environment should be the two top considerations when selecting a mining conveyor belt.

ABOVE OR UNDERGROUND?

The key difference between above-ground and underground mining belts is the materials used in the manufacturing process. A standard surface or above-ground mining conveyor belt is composed of highly flammable petrochemicals. If used in an underground mining application, there&#;s a good chance that the belt can combust and present a severe safety hazard. 

UNDERGROUND

Underground mining belts are made of flame-resistant materials. Special agents, impregnation paste, and rubber components are added during manufacturing to help decrease the friction factor and increase fire resistance.

SURFACE/ABOVE-GROUND

The selection of an above-ground conveyor belt is mainly determined by the properties of the raw materials you&#;re transporting. The levels of humidity, granularity, and abrasion characteristics are all essential factors in this decision. 

For example, highly abrasive materials such as iron ore, metallurgic coke, and quartz will require a much sturdier belt than moderately abrasive materials, such as ash or sand.

NATURE OF MATERIAL TRANSPORTED 

Under ideal conditions, the average lifespan of a mining conveyor belt is anywhere from three to ten years, depending on length, transfer design, etc. The nature of the bulk materials you&#;re transporting can also significantly affect belt lifespan. 

For example, sharp, jagged, abrasive materials can damage the belt much faster. This is why it&#;s important to choose a belt that&#;s specifically designed for your application and is well-supported in the loading zone.

FIREPROOFING

If your mining conveyor operates in an underground environment, it likely has to comply with MSHA Part 14 fire resistance requirements. Make sure you&#;re fully aware of the rules and regulations that can impact the type of belt you select for your conveyor to ensure you&#;re operating at maximum levels of safety, not to mention staying compliant.

SERVICE LIFE

Some belts are made to last longer than others, and certain factors like longevity and durability are important based on the particular type of environment. 

Conveyors running underground or transporting material from mines and quarries pose greater demands on the conveyor belt than a line in a factory transporting empty boxes.

Understand your needs when it comes to durability and ruggedness. Failure to consider this could result in productivity loss and increased downtime.

PULLEY DIAMETER

Depending on the thickness of the belt fabric from top to bottom, there is a manufacturer-recommended pulley diameter that you&#;ll need to consider.

CORROSION-RESISTANCE 

Belts can corrode&#;especially those that incorporate metals into their makeup. While corrosion may not be as much of a worry in a climate-controlled facility, it can pose challenges on underground conveyors where temperatures, UV light, moisture levels, and humidity tend to fluctuate.

BELT WIDTH & LENGTH 

Since all belts aren&#;t made for the same applications, they aren&#;t constructed in similar widths or sizes. 

For example, the belts you see on the conveyor belt systems in grocery store checkouts are much smaller in width and length than the ones you&#;d find underground transporting products from the mine. 

While many belts can be custom-made to fit a desired length and width, it&#;s always best to know your sizing requirements.

TEMPERATURE

The temperature of the materials you&#;re transporting is another vital consideration. For example, rock and ore that come straight from the ground could be as hot as 220°F. While this is not enough to catch the belt on fire, it could potentially cause irreparable damage. 

A belt designed with specific thermal properties can help mitigate damage caused by high-temperature materials.

Conveyor systems in mining can range from simple belt conveyors used to transport ore to complex systems integrating multiple types of conveyors, feeders, and elevating mechanisms. They are utilized in both surface and underground mining operations for the movement of bulk materials such as coal, ore, and overburden, facilitating a continuous and reliable flow of materials.

What are the three types of conveyor?

The three main types of conveyor systems are belt conveyors, roller conveyors, and chain conveyors.
Belt Conveyors are the most common and versatile type, used for transporting materials over short to long distances, either horizontally or at inclines. They consist of a continuous belt that moves over rollers or a flat surface, carrying materials from one point to another.
Roller Conveyors utilize a series of rollers to move goods. They are best suited for handling solid items or containers and are commonly used for sorting, assembling, and loading processes. Roller conveyors can be powered or gravity-operated, depending on the application&#;s needs.
Chain Conveyors are designed to transport heavy loads and are typically used in applications where rugged, durable conveyance solutions are required. They consist of a series of short, interconnected links or chains that move over sprockets, ideal for moving bulky or heavy materials that are unsuitable for belt or roller conveyors.

What is the most common conveyor belt system?

The most common conveyor belt system is the flat belt conveyor. Flat belt conveyors are widely used across various industries due to their simplicity, efficiency, and versatility. They consist of a flat belt that moves over pulleys and rollers, transporting materials from one point to another. Flat belt conveyors can handle a wide range of materials, from small, delicate parts to large, bulky goods. They are easily customizable to fit specific operational requirements, such as speed, load capacity, and the inclusion of sidewalls or cleats to prevent spillage. Their widespread application includes assembly lines, packaging, sorting, and material handling tasks in manufacturing, warehousing, and logistics operations.
