There is an endless number of types and uses for conveyor belts. All of the varieties serve the purpose of transporting materials and goods along a continuously moving path. Though motorized conveyor belts are the traditional form of a conveying system, there are systems that use rollers without a motor to move materials.

Chapter Two - Types of Conveyor Belts

The range and uses of conveyor belts cover several industrial settings and applications. The efficiency of conveyor belt systems assists in improving productivity, saves on labor costs, and decreases lead times. Conveyor belts move large quantities of goods quickly and reliably for transport, further assembly, or storage.

The principal reasons so many conveyor systems are in use are the savings in labor costs, efficient movement of goods, and their ability to keep products and materials from damage. They provide the best possible service at the lowest possible cost.

Types of Conveyor Belts

Roller Bed Conveyor Belt

The surface of a roller bed conveyor belt is a set of rollers that match the weight and speed required by the product. The length of the roller bed conveyor belt determines the number of rollers to be used.

A roller bed conveyor belt is designed for applications where materials are loaded by gravity. They are an ideal solution for conditions where materials have to be moved over long distances since they are designed to reduce friction.

Chapter Three - How Conveyor Belts Work

As essential as conveyor belts are to the efficiency of various industrial operations, it is easy to summarize their operation. In essence, a conveyor belt is a very large wide belt that is similar to a huge rubber band affixed to rollers in the shape of a loop connected to rotors powered by a motor. The loop in the design is the conveyor belt, which is made of various types of sturdy and durable materials.

(Video) How the braking system works? Types of brake disc (Car Part 4) ABS

The design of the belt provides structure and traction for the movement of goods and material.

How Conveyor Belts Work

Motor

The motor on a conveyor belt turns the rotors that move the conveyor belt. There is a sufficient amount of friction between the belt and the rotor for the belt to stick to the rotor. The turning motion of the rotors causes one side of the belt to move in one direction, while the other side moves in the opposite direction. The different motions produce the movement of the conveyor belt.

Chapter Four - How Conveyor Belts are Made

Regardless of the material used to produce a conveyor belt, all types are designed to move products, materials, supplies, and components efficiently and smoothly from one point to another. The design of the belt determines the products and industries the belt is best suited to serve.

Though there is a long list of materials used to make conveyor belts, all varieties fall into five categories: metal, plastic, rubber, fabric, and leather. There are subgroups and variations within each category that produce the many varieties.

How Conveyor Belts are Made

Plastic Conveyor Belt

Plastic conveyor belts are lightweight and temperature resistant belts that are made of thermoplastics such as polyurethane, polyester, polyvinyl chloride, silicone, and polyethylene. To allow for bending, curving, and incline or decline motion, plastic conveyor belts have interlocking segments that give them the flexibility to move in any direction. Interlocked plastic conveyor belts are an alternative to metal and fabric belts.

Metal Conveyor Belt

Woven metal or plate conveyor belts are extremely strong, durable, rigid, and flat. They do not change shape, stretch, or deform over time. Metal conveyor belts run in a straight line without curves, turns, or variations in their path. They are made from stainless steel, aluminum, or carbon steel and have exceptional longevity.

Rubber Conveyor Belt

Rubber has been a conveyor belt material for many years and is one of the more durable choices due to its abrasion resistance. The types of rubber used for conveyor belts include neoprene, nitrile, and styrene butadiene, all of which are reinforced with cloth fabric.

The durability of rubber makes it ideal for harsh conditions where abrasion resistance and impact absorption are necessary. The cloth reinforcement prevents the rubber from stretching and deforming.

What Is It? How Does It Work? Types, Parts (24)

Fabric Conveyor Belt

Fabric conveyor belts are a cost effective choice for short conveying systems with lower capacity. The belt is made of several layers of synthetic fabrics that are specially treated to prevent elongation and have lengthwise polyester threads with crosswise polyamide threads. The combination of the two thread patterns provides an exceptional tensile strength to weight ratio and flexibility as well as resistance to impact and chemicals.

Various grades of rubber are used as cover materials to meet the needs of a variety of conveying applications. Rubber cover grades are added to fabric conveyor belts to make the belts resistant to fire, heat, and wear.

The types of fabric conveyor belts are:

  • Nylon - durable, heat resistant, impact resistant, and will not mildew.
  • Polyester - has all the features of nylon but is less expensive and operates more quietly.
  • Kevlar - flame retardant, impact resistant, made of thick fibers, and runs faster and longer than other fabrics.
  • Natural - made of woven cotton and wool.

Chapter Five - Uses for Conveyor Belts

Conveyor belts can be found in any industry that requires the movement of materials or supplies from one position in the facility to another position. In small manufacturing businesses, it may not be necessary to have a conveying system since parts and components can be moved using a hand cart. Larger more complex facilities require an automated system for efficiency, saving of time, and productivity.

(Video) 1950 Chevy Pickup Truck - Part 5: E-Level Sensors

The varieties and uses for conveyor belts range between small conveyors used to move jewelry and precious stones to gigantic conveyors that remove rocks, coal, and stones. When there is a need for the rapid and economical movement of materials, it is likely that a belt conveying system will be used.

Uses for Conveyor Belts

The various uses of conveyor belts can be broken into the categories of general and bulk material handling, food processing, and manufacturing and assembly operations.

Bulk Materials

Bulk conveyor belts are used to handle very fine and granular materials as well as large lumped sized materials. Cement, sand, and gravel are moved and loaded using belt conveyors. In the mining industry, coal, minerals, rocks, and stones need to be removed from mine shafts and open pit mines to get to the raw materials. Belt conveyors of varying lengths are extended into the operations to remove minerals and refuse.

Ship Loading and Unloading

Mobility is a crucial factor regarding the loading and unloading of ships. In the loading process, a belt conveying system unloads trucks and moves materials into the hold of a ship. For unloading, the process is reversed, and materials are moved from the ship and conveyed to trucks. Due to the unique nature of shipping and the different types of ships, loading and unloading belt conveyors are able to adjust to the height of the ship by telescoping.

Line Automated Assembly

Assembly operations have a series of conveyors that are custom designed to fit the needs of the operation. As more and more assembly operations are using robotics and automated processes, belt conveying systems are being rapidly developed to meet the many computerized innovations and operational demands.

The varieties of belt conveyors used for automated assembly lines include chain, slider, hinged, plastic belt, and pallet. The increasing demand for rapid and efficient material movement has necessitated the creation of new and unique belt conveyor configurations.

Luggage Transport

Belt conveyors are a necessary part of all airport operations in order to provide fast and efficient movement of packages, cargo, and luggage. For a belt conveying system to be successfully integrated into airport material handling, it must be able to meet the needs of all other handling and checking systems.

The specifications for airport belt conveyor systems include reliability, silent operation, appealing appearance, safety, and ease of maintenance. Every airport belt conveyor system is tailored and designed to meet the specific requirements of the airport‘s layout such as angles, flow rate, and one or two way operation.
