The sidewall belt conveyor is a specialized type of belt conveyor designed for conveying bulk materials at large angles and vertically. It finds extensive application in industries such as coal, chemical engineering, cement, grain, biomass, and others, enabling the transportation of various materials.
This conveyor utilizes a belt with corrugated side guards and cross partitions. Its allowable conveying angle can reach up to 45 degrees, making it an ideal solution for large-angle conveying and vertical lifting of materials. This design not only conserves floor space but also reduces equipment investment and construction costs, offering significant comprehensive economic benefits. For instance, if a user needs to lift coal into a silo at a height of 0 meters, using a conventional conveyor with an allowable angle of 16 degrees would require a machine length of 72.6 meters (horizontal length: 8.8 meters). In contrast, employing a 45-degree guard edge conveyor reduces the machine length to 23 meters (horizontal length: 20 meters), while a vertical guard edge conveyor can limit the machine length to within 6 meters. The structure is simple, and all primary components of this series are interchangeable with those of standard belt conveyors, facilitating ease of use and maintenance. Operation of the sidewall belt conveyor is reliable, avoiding common issues such as jamming, chain slipping, or chain脱落 observed in traditional belt conveyors and chain hoists. Additionally, it eliminates bucket slippage and detachment problems often encountered in bucket elevators. Its reliability is comparable to that of general-purpose belt conveyors. The conveyor operates smoothly with low noise levels. Furthermore, this series of products exhibits low energy consumption due to the absence of loading resistance and internal friction during operation, unlike buried plate conveyors. For example, at the lu nan chemical plant, two vertical guard edge conveyors with a conveying height of 19.2 meters and a conveying capacity of 25 tons per square meter were installed. Each has an installed power of only 4.5 kw, significantly lower than the total installed power of 44 kw required by the four original scraper conveyors they replaced.
The sidewall belt conveyor can incorporate horizontal conveying sections of any length at the head and tail, facilitating seamless integration with other equipment. As a continuous conveying device for general-purpose bulk materials, it is widely applicable in industries such as coal, grain, building materials, construction, metallurgy, chemical engineering, and light industry. It can transport various bulk materials with a specific gravity ranging from 0.5 to 2.5 t/m³ within an environmental temperature range of -25°c to +40°c. The maximum conveying angle is 45 degrees, and the largest material size it can handle is 550 mm. When conveying materials with special requirements, specialized corrugated guard edge conveyor belts should be employed.
To achieve optimal receiving and discharging conditions, particularly when the conveying angle exceeds 45 degrees, this series recommends "S" And "Sc" Layout types. These configurations feature a lower horizontal receiving section and an upper horizontal ascending receiving section for the guard edge machine.
The sidewall belt conveyor primarily consists of the head hopper, head frame, head guard cover, drive drum, head cleaner, guard edge, convex section frame, idler, middle frame, middle frame support, upper support, concave section frame, idler, lower support, discharge chute, empty section cleaner, tail frame, tensioning device, and tail frame, among other components. The corrugated guard edge conveyor belt serves dual functions of traction and bearing in the guard edge machine. It comprises a base belt, corrugated guard edges, and cross partitions. The corrugated guard edges are adhered to both sides of the base belt, while the cross partitions are attached at specific intervals between the two sides of the guard edges.
The base belt of the corrugated guard edge conveyor belt shares the same shape as a standard conveyor belt but generally exhibits greater lateral stiffness. This series employs specially manufactured conveyor belts as the base belt, with tensile materials (core layers) available in four types: Cotton canvas, nylon canvas, polyester canvas, and steel wire core. Specifications and technical parameters for the base belt include options for cotton canvas, nylon canvas, and polyester canvas.
