1、 Structure:

1. Covering glue: upper covering glue+lower covering glue

The purpose of covering adhesive is to protect the fabric core from wear, impact, water, and other harmful effects. There are ordinary and special types of covering adhesive according to different usage situations. Special types can meet special requirements such as wear resistance, oil resistance, heat resistance, flame retardancy, acid and alkali resistance.

2. Skeleton layer: Polyester fabric (polyester+polyamide), nylon (nylon+nylon), cotton canvas (cotton thread+cotton thread) The fabric core of the belt maintains the tension of the belt and supports the strength of the structure, almost bearing all loads during operation.

3. Core adhesive: It has good fabric adhesion, making the canvas tightly bonded together. It increases the bending life of the belt and makes the connection between the fabric layers more elastic, so that the fabric layers will not separate during the operation of the belt.

2、 Advantages:

Excellent rubber adhesion, impact resistance, low elongation, high modulus, good flexibility, and good groove forming ability

Suitable for material transportation under long-distance, high load, and high-speed conditions

3、 Application:

1. Cement plant, concrete mixing plant

2. Quarry and sand quarry

Conveyor belting comprises two essential components: the inside carcass and the outer covers. The carcass serves as the belt's core structural element, tasked with supporting the load of cargo conveyed on the conveyor. Its primary function is to transmit the tension required to lift and move the loaded belt, while also absorbing the impact energy generated as material is loaded onto the belt. If the carcass fails to manage this initial impact energy, regardless of the belt-support system used, premature belt failure can occur. The carcass must be adequate to allow proper splicing techniques and strong enough to handle the forces that occur in starting, moving, and stopping the loaded belt. The carcass also provides the stability necessary for proper support between idlers and for maintaining alignment.

Most carcasses consist of one or more plies of woven fabric, although heavy-duty belting may integrate parallel steel cables to replace some or all of the fabric layers. Carcass fabrics typically feature yarns woven in specific patterns: warp yarns, running lengthwise parallel to the conveyor and bearing tension; and weft yarns, positioned transversely to enhance impact resistance, mechanical fastening, load support, and overall fabric stability.

Historically, conveyor belts utilized cotton yarns for textile reinforcement, often incorporating a breaker fabric between the cover and the carcass to improve cover adhesion and resistance to wear.

During the s and s, there was a shift in carcass reinforcement materials, with modern conveyor belts predominantly utilizing synthetic fabrics such as nylon, polyester, or their blends. These materials offer superior strength, adhesion, resistance to wear and abuse, fastener holding capacity, and extended flex life compared to traditional natural fabrics. In some specialized applications, fabrics incorporating aramid fibers are employed, providing exceptional strength, minimal elongation, and heat resistance. However, breaker fabrics are seldom used with these synthetic fabrics due to limited additional benefits.
