Rubber conveyor belt

What is a rubber conveyor belt?

Rubber conveyor belt is a continuously moving belt made primarily of rubber or rubber-like material used to transport goods, materials or items from one place to another in a variety of industries. These belts are widely used due to their durability, flexibility and ability to withstand a wide range of loads and environmental conditions. They are usually constructed of a multi-layer structure, including a rubber outer layer for protection and a fabric or steel cord core for strength and stability.

The rubber belt has a smooth surface and moderate friction, which can ensure the smooth movement of materials during transportation, reduce spillage and loss, and is especially suitable for conveying materials in various forms such as granular, blocky and powdery. At the same time, it can realize horizontal, inclined and even vertical transportation, and can flexibly adapt to different sites and process requirements, easily cross obstacles and change the direction of transportation.

What are the classifications of rubber belt conveyors?

Rubber conveyor belts can be categorized into horizontal, inclined, and Z-type conveyor belts based on their application scenarios and structural characteristics. These three types of conveyors are primarily used for transporting materials across flat surfaces or at different heights. Their operating principles, scope of application, and design differences constitute the primary classification of rubber conveyor belt systems. The following is a detailed introduction to these three types:

Horizontal rubber belt conveyors:

Features: Used for horizontal or nearly horizontal (≤10°) material transportation, suitable for long-distance transportation of bulk or piece goods.

Application: Suitable for production lines and assembly lines within factories, as well as scenes where various items need to be transported smoothly and continuously, such as packages, electronic products, food, etc.

Inclined rubber belt conveyors:

Features: The inclination angle is usually 10°~25° (special designs can reach 30°), suitable for climbing conveying, and anti-slip belt surfaces (such as patterned belts, sidewalls or diaphragms) are required to prevent materials from slipping.

Application: Widely used in occasions where materials need to be lifted to different heights or for vertical material transfer during production. The selection of the inclination angle needs to take into account the characteristics of the material to prevent the material from falling back or slipping.

Z-type rubber belt conveyor

Features: Rubber belt conveyor combines the characteristics of horizontal and inclined conveying to form a "Z"-shaped layout (with an inclination of up to 90°), which can effectively lift materials from a lower horizontal plane to a higher horizontal plane and connect them through the inclined section in the middle.

Application: It is suitable for occasions where a large height lifting is required but a long inclined conveyor cannot be used due to site restrictions. It can realize the vertical lifting of materials and the connection of horizontal conveying, and is often used for loading and unloading materials or transferring materials between different floors.

What are the different types of rubber conveyor belts?

Rubber conveyor belts can be classified into single-layer fabric rubber conveyor belts and multi-layer fabric rubber conveyor belts according to the material of the conveyor belt. According to different application scenarios, multi-layer fabric rubber conveyor belts can be divided into heat-resistant, high-temperature resistant, wear-resistant, fire-resistant fabrics, food safety textile rubber conveyor belts, etc.

Single-ply textile rubber conveyor belts

Construction: Excellent resistance to bending fatigue, impact and shock resistance, and excellent grooving properties.

Features: Single-ply carcass provides tension in excess of 2000kN/m. Low elongation allows for short take-up strokes.

Purpose: Single-ply textile rubber conveyor belts are developed to withstand the most demanding conditions and heavy industrial use, conveying large amounts of material.

How does the rubber conveyor belt work?

Loading: The material is placed on the belt at the loading point, and the flow is usually controlled by a hopper or chute.

Transport: The rubber conveyor belt transports the material along its path during movement.

Discharging: At the discharge end, the material is released by gravity (when the rubber conveyor belt bends around the tail pulley) or other equipment.

What is the structure of Rubber conveyor belt？

Rubber conveyor belts are usually composed of the following layers: covering rubber (surface layer), skeleton material (reinforcement layer), bonding layer and edge protection

Covering rubber: It must have the characteristics of wear resistance, impact resistance, corrosion resistance, etc., and is divided into upper covering rubber (thicker) and lower covering rubber (thinner).

Skeleton material: including canvas layer (commonly used polyester, nylon, cotton fiber, etc., to provide tensile strength) and wire rope core (such as long-distance, large-volume transportation).

Adhesive layer: ensures the close bonding of rubber and skeleton material.

Edge protection: Some conveyor belts are designed with tear-resistant edges or sidewall structures.

Rubber Conveyor Belt Accessories

As a complete conveying system, a rubber conveyor belt requires not only the conveyor belt itself but also many key components to work together to ensure stable operation. These components include support and drive components, protective and auxiliary components, and safety and control components.

Idler rollers: These are common components in conveyor belt systems, acting like the "wheels" of the conveyor belt. Rollers are installed on the conveyor frame to support the conveyor belt and the material on it. Depending on their function, they are classified as load rollers (supporting the conveyor belt and material above) and return rollers (supporting the empty conveyor belt below). Their quality and arrangement directly impact the smoothness and service life of the conveyor belt.

Rollers: The rollers are the core components that drive the conveyor belt.

Drive rollers: Driven by an electric motor, they are the power source of the entire system, driving the conveyor belt forward through friction.

Bend rollers: They change the direction of the conveyor belt, for example, at the end of the conveyor belt, allowing it to form a closed loop.

Tensioners: Conveyor belts stretch and deform during operation. The tensioner's function is to adjust the belt tension to maintain the proper tension and prevent slipping and deviation. Common tensioning methods include spiral tensioning and weight tensioning.

Cleaners: Mainly installed at the discharge end of the conveyor belt, they remove residual material from the belt surface. This prevents material from sticking to the conveyor belt and causing contamination or damage, and protects the rollers and idlers from wear. Chutes and Skirts: At the conveyor belt's loading point, the chutes guide the material smoothly onto the conveyor belt, while skirts are installed on both sides of the chutes to prevent material from spilling during loading.

Frame: The "skeleton" of the entire conveyor belt system, supporting all components, including rollers and drums, and ensuring the overall structural stability of the system.
