From understanding how they function to knowing the names of their components, having the right conveyor belt information can come in handy for someone who is looking to replace or repair a belt.
Conveyors can be complex, and so can the terminology that comes with them. In this blog, we will provide you with conveyor belt terminology and definitions to help navigate the industry.
Conveyor Glossary
We have broken our conveyor glossary into 5 parts of basic conveyor belt terminology, including industries, types of conveyor belts, types of pulleys, types of idlers, and types of drives.
#1 Common Industry Types
The first part of our conveyor glossary covers specific types of conveyor belts used in a variety of industries.
High-Temperature Industrial
Conveyor belts play a major role in industrial manufacturing processes and therefore need to be able to function in high-temperature conditions. High-temperature industrial belts have characteristics that allow them to withstand temperatures ranging from 1,000 ℉ to 2,300 ℉. Learn how to choose the right belt for high-temperature industrial manufacturing environments.
Food Processing
The food processing industry also uses conveyor belts for a variety of purposes. These belts are made from a variety of materials depending on the application. Choose the best food processing belt for your application.
Packaging/Material Handling
A packaging and material handling conveyor belt is designed to assist with product packaging such as placing finished products in containers, adding labels, or preparing products for shipping. They provide a safe method of moving materials without the need for employees to carry the items. If you need help choosing the right belt for the packaging/material handling industry, Wire-Mesh experts are here for you.
#2 Belt Types
This section of our conveyor glossary covers specific belt types based on weave and components.
Balanced Weave
This weave is one of the most common and versatile types featuring a series of left and right-hand wire mesh spirals joined by a connecting or crimped rod. Check out our guide if you need help knowing how to measure a balanced weave belt.
Compounded Balanced Weave
A balanced weave comprised of left and right-handed spirals compounded together. Check out our guide if you need help knowing how to measure a compound balanced weave belt.
Double Balanced Weave
A weave with left and right-hand wire mesh spirals that have two interwoven left-hand spirals and two interwoven right-hand spirals. Check out our guide if you need help knowing how to measure a double-balanced weave belt.
Rod Reinforced
This type of weave resembles a chain link fence featuring a series of interwoven spirals.
Flat Flex
This type of weave offers a lightweight, open area, with the thinnest positive drive wire. Check out our guide if you need help identifying a flat flex belt.
Flat Wire
In this type of weave, conveyor belting is made from carbon or stainless steel strips that are driven by cast or mechanical sprockets.
#3 Rollers
The next section of conveyor belt terminology covers different rollers and roller systems. A roller is an external component that controls the belt’s movement.
Typically, a conveyor system will have at least two rollers, one operating under power and the other idle. However, more complex conveyor systems may have multiple rollers along the frame.
Drive or Head Roller
Coupled with the actuator and electric motor, this component drives the conveyor acting as the pulling force. It can be loaded at the front or rear of the conveyor. The drive pulley is typically the largest in diameter.
Tension Pulley
This is a return pulley used to create tension on the conveyor belt, increasing the force placed on the pulley.
Snub Pulley
These pulleys work with the drive pulley by increasing friction to enlarge the touching areas between the belt and the drive pulley.
Crowned Head Pulley
A pulley that features cylindrical middle and tapered ends to assist the conveyor belt to be driven without wobbling.
Flat Face Pulley
This is a type of pulley on which the face is a straight cylindrical drum.
#4 Idlers
This section of the conveyor glossary talks about idlers, which are non-powered rollers that work to support the belt.
Idler Roller
Employed along the length of the belt to support the belt and the load, these rollers help prevent sagging, align the belt, and clean up any carryback.
Rubber Disk Idler
This idler features rubber disks placed at set distances along the axis of the roller to help break off connected carryback/leftover material as well as reduce material buildup at the bottom of the belt.
Screw Idler Roller
An idler that features helical-like disks (similar to a screw) on the roller and is often used in place of a scrapper to remove carryback.
Trainer Idler
Made to keep the belt running straight, this idler works against mistracking by using a central pivot that swerves the roller back to the center when the belt drifts to one side. These also include two guide rollers which act as guides for the belt.
#5 Types of Drive Units
The final part of our conveyor belt terminology guide covers types of drive units. These are the necessary structural, mechanical, and electrical parts that provide the motive power for a conveyor.
Usually consisting of a motor/reducer, chain, sprockets, guards, mounting base, and hardware. This allows the belt to shift into reverse and handle repeated changes in direction that some conveyor belts require.
Internal Drive
The drive pulley and motor are one assembly (the motor is housed within the pulley).
Center Drive
The drive assembly is located along the center of the conveyor frame. Generally speaking, this drive can be placed anywhere along the conveyor frame, what makes it a center drive is that the motor doesn’t engage either of the end pulleys or rollers.
End Drive
The drive assembly is located at one of the conveyor’s ends. Typically, the drive will be located at the discharge end of the conveyor so that it is pulling the belt or chain over the pulley. Other times the drive is placed at the infeed, where it will be pushing the belt or chain over the drive pulley rather than pulling it.
Remember, this conveyor belt terminology guide is only the beginning. There are many more terms in the industry, but using this will help anyone who is looking to have the necessary conveyor belt information they need before repairing or replacing a belt of their own.
