FAQs about Troughing Roller
A troughing roller is a key component found in conveyor systems, particularly bulk handling conveyors. It is designed to support and shape the conveyor belt to form a ‘trough’, which helps contain the material being transported. This is achieved through a specially designed roller assembly featuring rollers angled at about 20 to 45 degrees on either side of a flat, center roller. The angles form the shape of a trough, hence the name “troughing roller”.
Idler rollers, also known as conveyor rollers, serve a critical function in conveying systems. They are primarily designed to support and shape the conveyor belt, essentially facilitating the smooth transport of materials. Idler rollers also help reduce the drag and friction generated during the conveyor belt’s operation. Additionally, they play a significant role in maintaining the belt’s alignment, reducing the likelihood of belt wander, and mitigating the damage caused by potential material buildup. Despite their seemingly basic function, idler rollers are integral to maintaining the efficiency and longevity of conveyor systems.
The angle of a troughing idler, also known as the trough angle, typically ranges from 20 to 45 degrees. This angle is created by positioning the side rollers at an incline relative to the flat center roller, forming a ‘trough’ shape. The precise angle used can be adjusted depending on the requirements of the material being transported and the specific conveyor design. A larger angle forms a deeper trough and can help contain more material, but it can also contribute to more belt strain and increased power requirements for the conveyor.
Roller conveyors are differentiated mainly based on their configuration and the type of operation they’re designed for. The three primary types include:
Gravity Roller Conveyors: These are non-powered conveyor systems where products are moved using gravity or manual pushing. They are commonly used for simple applications, such as moving boxes or pallets.
Chain-Driven Roller Conveyors: In these systems, a chain links all rollers together, moving them at the same time. These types are often used for heavy items, like pallets and industrial containers.
Line Shaft Roller Conveyors: These conveyors have a shaft that runs the length of the conveyor. The shaft, powered by a motor, provides the drive for each roller individually through belts and pulleys. They are typically used in packaging and manufacturing for lighter loads.
Each type is designed for different use cases and offers a distinct set of advantages catered to specific operational needs.
