Belt conveyors are moving and carrying belts that ride on pulleys or rollers (two or more) that rotate around the belts and build a pull effect to drive the materials from one place to another. Today, they have become an indispensable tool in any material handling industry.
They are also called conveyor belts. Their main aim is to carry any material or especially large materials in less time and without any workforce.
Belt conveyors are used across many industries. Each industry uses different types of belt conveyors according to their specs and requirements. With the help of belt conveyors, materials or goods move from the beginning to the end in bulk while maintaining the quality.
Just think of the hours of the workforce we would be blowing if we won’t have belt conveyors. In a nutshell, belt conveyors are the tried-and-true choices because of their ease and reliability. Let’s find out about its applications in depth.
- Belt conveyors are widely used in many industries. They make our work accessible by moving all sorts of bulk materials throughout their processes and thus reducing our operational time and costs.
- You will easily find belt conveyors at an airport. They are placed for organizing, loading, and unloading the luggage efficiently. They are a fusion of conveyor belts and advanced baggage handling systems.
- In the pharma industry, transportation of cardboard boxes full of medical supplies throughout the entire process of packaging and distribution is carried out by belt conveyors.
- Belt conveyors are also widespread among the logistics and warehouse industries to make sure items precisely sail around the system.
- Another use of belt conveyors is handling raw materials like food grains, molding sand, molding-cores, or moving them from place to place. They can be carried over tilts or bends with the help of belt conveyors.
- In mining and power plants, large amounts of material like coal, ores, and minerals are transported through tunnels, roads, and slopes on conveyor belts.
- In the food industry, products go through most of the processes on a conveyor belt. Items can be spread, sliced, powdered, cooked, or even branded — everything while riding on the belt.
- Belt conveyors are not merely used in large industries for carrying heavy materials. You might also have grabbed your food from a bowl or one of your plates in a fancy restaurant through such belt conveyors systems.
- Belt conveyors can also be seen in public places when we are moving our groceries to the cash counter in a supermarket, or the escalators while shopping in a mall, or moving skiers up to a slope, etc.
How does it work?
A belt conveyor is just a thick, broad, and durable belt attached to the conveyor in a loop form. The belt is fixed with two or more pulleys, rotors, or drums powered by motors.
The looped part is known as the conveyor belt and is usually made up of several layers of materials as per the use. The first layer gives formation to the belt, and the second layer helps in the transportation of the materials.
When the motor runs, the pulleys, rotors or drums turn. This turning causes the conveyor to start spinning in a single direction due to its friction with the belt.
If the belt conveyors are to be used at places where usually large or bulky objects are carried for a long-distance or duration, rollers are installed on the sides for support. They hold objects in position and keep the belt from weakening.
Following are the principle components of belt conveyors
- Drive Mechanism
- Loading & Discharging Devices
The belt is the most crucial part of the belt conveyors used to carry the load. It is made of several layers: a top cover, a carcass, and a bottom cover. The carcass provides strength and shape. The material of the layer is chosen as per the working requirement. They are usually available in different materials like rubber, polymer, etc.
Idlers are very much essential in the conveying process. They allow the conveyor belts to bear more load and move smoothly. Rollers hold up the belt and rotate the conveyor preventing the belt from sagging, stretching, or failing due to the pressure. Idlers vary from the length, diameter, and types to suit the belt’s width, the speed of the system, and the weight they need to carry.
There are two main types of conveyor idlers: carrying idlers and return idlers. Carrying idlers support the belt that moves the material, while return idlers support the empty belt.
The drive mechanism is the part that keeps the belt in its particular loop while moving the objects. Their speed is adjustable. The capacity of the motor ensures the speed level of the device.
A pulley in a belt conveyor system is a tool that changes the direction of the belt in a conveyor system, turns and imposes tension on the belt.
Commonly, pulleys are set at the ends of the conveyor. Latest pulleys are made of rolled shells, end disks, shaft, hub and locking assemblies.
- Drive/Head Pulley – Used for driving a conveyor belt. They are usually installed in outer bearings and operated by an external drive source.
- Idler Pulley – Used in a non-drive position designed to rotate smoothly and driven by the belt.
- Take-up Pulley – Used for eliminating slack and providing tension to a conveyor belt. They are well-known in conveyors of longer lengths.
- Return/Tail Pulley – Used for redirecting a conveyor belt back to the drive pulley. Tail pulleys can use internal bearings or be put at external bearings and are placed at the end of the conveyor belt. They generally serve the purpose of a Take-Up pulley on conveyors of shorter lengths.
- Snub Pulley – Used for increasing belt wrap around a drive pulley for improving traction.
- Bend Pulley – Used for redirecting the belt and producing belt tension where bends occur in the conveyor system.
There is an arrangement for the loading & unloading purposes in a belt conveyor system, which is called a chute. It is used to load the material & also collect the goods at the system’s outlet.
