How many types of large inclination belt cores are there?

Large angle belt conveyor and ordinary belt conveyor is completely different, common trough belt conveyor, to trough rollers, smooth conveyor belt; and large angle belt conveyor conveyor belt, due to the transport characteristics of the problem, for the skirt spacer conveyor belt.
Belt core in fact, whether it is ordinary conveyor belt or corrugated edge spacer conveyor belt, the type of belt core used are the same kinds, mainly presenting different appearance. It should be noted that the skirt and the partition on the skirt partition conveyor belt are not affected by the belt core, and they are all of one type.
As a mining belt conveyor, generally more black rubber conveyor belt, core material used for nylon, canvas, wire rope core more. Its characteristics are wear-resistant, optional corrosion resistance, acid and alkali resistance, high temperature resistance, cold resistance and other special material requirements of the tape.

Tape core mainly has the following types:

1. Fabric core (layered type)

Material: usually made of multi-layer polyester (EP), nylon (NN) or cotton fiber fabrics soaked and glued together.

Features:

Good flexibility, suitable for small and medium inclination (generally need to be used with baffle and spacer).

Lower cost, but the longitudinal tensile strength is weak, not suitable for large inclination angle or heavy load conditions.

Application: suitable for inclination angle ≤ 30 ° occasions, need to be matched with corrugated baffle and cross partition.

2. Steel wire rope core (ST type)

Material: high-strength steel wire rope arranged longitudinally and covered with rubber covering layer.

Features:

Extremely high tensile strength (up to 8000N/mm² or more), suitable for long distance, large inclination angle (up to 60° or more), heavy load transportation.

Lateral flexibility is poor, need special design of baffle and partition structure.

Application: Mining, harbor and other large inclination angle, high intensity conveying scenes.

3. Integral woven core (PVG/PVC)

Material: Integral braided polyester or nylon fiber, covered with PVC or PVG rubber.

Features:

Moisture-proof, good flame-retardant performance (commonly used in coal mine).

Tight structure, strong lateral tear resistance, suitable for dynamic bending conditions.

Application: Inclination angle ≤ 35 ° flame retardant requirements occasions (such as coal mines).

4. Steel mesh core

Material: metal mesh (stainless steel or carbon steel) embedded in rubber.

Features:

High temperature resistance, impact resistance, suitable for conveying sharp or high temperature materials.

Large weight, need to be matched with high-strength drive system.

Application: Metallurgy, cement and other industries, high temperature material conveying at large inclination angle.

5. Composite belt core (mixed structure)

Material: Combined with steel wire rope and fabric layer (e.g. steel wire rope + EP layer).

Features:

Balance longitudinal strength and transverse flexibility, adapt to complex working conditions.

Higher cost and greater design flexibility.

Application: Special needs of large inclination conveying (e.g. both high strength and corrosion resistance).

Selection points

Inclination Requirements: Over 30° usually requires wire rope cores or special edge/spacer designs.

Material characteristics: sharp materials need steel mesh core, corrosive environment need chemical-resistant belt core.

Strength requirements: wire rope core for heavy loads, fabric core for light to medium loads.
Different belt core types need to match the corresponding belt structure (such as baffle, partition, cover rubber, etc.) to realize the function of large inclination conveying. The actual selection should be combined with the working conditions to consult the professional manufacturer.
