What is the High Angle Belt Conveyor

The high angle belt conveyor represents a significant advancement in the field of material handling and transportation. These conveyors are specifically designed to operate at steep inclines, surpassing the capabilities of traditional conveyor systems.

Definition and Structural Overview

  • Definition: High angle belt conveyors are conveying systems that facilitate the transportation of materials at steep angles, typically beyond 20 degrees. They are engineered to handle a variety of materials, from bulk solids to smaller items, efficiently and safely.
  • Structural Components: These conveyors consist of two main components – the conveyor belt and a cover belt. Both belts move in endless paths and are supported by an array of idler rolls. The idler rolls are strategically placed to direct the belts upwards and downwards, accommodating the steep angle of operation.

Operational Mechanism

  • Unique Design for Steep Angles: Unlike traditional flat belt conveyors, high angle conveyors use a specialized design that allows them to operate effectively at steep inclines. This design includes features like sidewalls and cleated belts to prevent material spillage.
  • Material Handling Capacity: High angle belt conveyors are capable of handling a wide range of materials, from fine particles to large bulk solids. Their design ensures that materials are securely transported up steep inclines without backsliding or spillage.

Traditional Conveyor Systems

FAQs about High Angle Belt Conveyor

What is a high angle conveyor?

A high angle conveyor is a type of conveyor system that is designed to transport materials at steep angles, typically upward. These conveyors are capable of handling materials at angles that are much steeper than the conventional conveyor systems, often up to 90 degrees. High angle conveyors are used in situations where space is limited or when the material needs to be elevated to a significant height. They are commonly used in mining, construction, and other industries where efficient vertical transport of materials is required.

What is the maximum angle for a belt conveyor?

The maximum angle for a traditional flat belt conveyor typically ranges up to about 20 degrees. However, this can vary depending on the material being transported and the type of conveyor belt used. For materials that are more prone to sliding or rolling back, the maximum angle might be less. Specialized conveyor systems, like high angle or steep angle conveyors, can handle steeper inclines, sometimes up to 90 degrees, using specific belt designs and additional holding mechanisms.

What is the angle of belt conveyor incline?

The angle of belt conveyor incline refers to the degree of slope at which the conveyor system is set to transport materials. This angle can vary widely depending on the application and the type of material being moved. For standard belt conveyors, the incline angle typically ranges up to 20 degrees. For applications requiring steeper inclines, specialized conveyor systems with unique designs are used.

What is steep angle conveyor?

A steep angle conveyor is a specialized type of conveyor designed to transport materials at steep inclines, typically greater than 20 degrees. These conveyors are engineered to handle steep inclinations, where standard conveyors would not be effective. Steep angle conveyors often feature unique design elements like sidewalls, cleated belts, or specific belt materials to maintain the material’s position on the belt and prevent slippage or rollback. They are commonly used in applications where space is limited or where materials need to be elevated quickly over a short horizontal distance.
