The large angle belt conveyor is a type of continuous conveying equipment featuring a corrugated sidewall and cross-cleat structure. Its primary distinction from conventional belt conveyors lies in the addition of flexible, corrugated vertical sidewalls and cross-cleats to the conveyor belt; these form a series of continuous "box-like" compartments, enabling the transport of materials at steep angles or even vertically.
The traction and load-bearing component of a large angle belt conveyor is a continuous rubber conveyor belt featuring corrugated sidewalls and transverse cleats. This belt loops around the drive pulley and bend pulley located at either end of the conveyor frame, forming a closed circuit.
Its working principle is as follows:
Drive Mechanism: The drive unit rotates the drive pulley; the friction between the pulley and the conveyor belt propels the belt along a predetermined path.
Material Loading: The corrugated sidewalls and transverse cleats form "box-like compartments" on the base belt; material fed from the loading chute enters these compartments.
Vertical Lifting: Material within the compartments rises along with the conveyor belt. During the ascent, material above the surface level may tend to slide back due to gravity, but material below this level remains stationary relative to the compartment, allowing it to rise steadily with the belt.
Discharge: Upon reaching the head section, the material is discharged through the discharge outlet under the combined influence of centrifugal force and gravity.
To optimize loading and discharge conditions, steep-angle belt conveyors typically employ a “Z-shaped” configuration, consisting of an upper horizontal section, a lower horizontal section, and an inclined section. The lower horizontal section handles material intake, while the upper section handles discharge; these sections are connected by convex and concave curved frame segments to ensure a smooth transition for the conveyor belt.
The most prominent advantage of large angle belt conveyors is their ability to operate at angles ranging from 0° to 90°. In contrast, standard flat-belt conveyors are typically limited to an inclination of around 18°;. This capability allows for steep-angle or even vertical lifting within a confined space, significantly reducing the required footprint.
Compared to other conveying equipment, large angle belt conveyors offer a conveying capacity that is 1.5 to 2 times higher.
Compared to traditional multi-stage conveyor configurations, the overall length of the equipment can be reduced by more than 50%.
The basic components of large angle belt conveyors are identical to those of standard belt conveyors, ensuring excellent component versatility and interchangeability.
The equipment operates reliably with low noise levels and requires minimal maintenance.
It should be noted that large angle belt conveyors do have certain limitations. The service life of corrugated sidewall rubber belts is generally shorter than that of standard flat rubber belts. Additionally, the presence of sidewalls and cleats increases running resistance, necessitating a higher-power drive motor. Maintenance is also slightly more complex than for flat belts, requiring professional attention for issues such as sidewall delamination or cleat damage.
With its unique capability for large angle conveying, compact structural design, and broad adaptability, the large angle belt conveyor has become indispensable core equipment in the field of bulk material handling. Whether used for inclined haulage in coal mines, ore hoisting in mining operations, or cement clinker transport in the building materials industry, this equipment consistently demonstrates its irreplaceable value. To fully realize the conveyor's performance potential and ensure the reliable operation of the production line, it is essential to thoroughly understand its working principles, accurately grasp its technical parameters, and strictly adhere to installation specifications during selection and operation.
