Customized Patterned Conveyor Belt for Efficient Bulk Material Handling
YUFENG Patterned Conveyor Belt, also known as chevron or herringbone conveyor belt, is a rubber conveyor belt designed with molded patterns on the working surface to improve grip during inclined material conveying. It consists of an EP or NN fabric carcass, rubber cover and integrated raised pattern layer, which are bonded through high-temperature vulcanization.
Compared with smooth conveyor belts, the patterned surface increases friction between the belt and conveyed material, helping reduce material sliding and rollback on inclined conveying lines. Different pattern structures, heights and carcass configurations can be selected according to conveying angle, material size, belt width and working environment.
YUFENG produces patterned belts with virgin rubber and high-strength EP/NN fabric carcasses. The product range covers general wear-resistant, flame-retardant, high-temperature, oil-resistant and low-temperature models for quarry, mining, cement, aggregate, logistics and other bulk material conveying applications.
What Are the Main Types?
Patterned conveyor belts are mainly classified according to the molded surface structure. Different patterns provide different levels of grip, cleaning performance and suitability for conveying angles.
Closed Chevron Belt
The closed chevron pattern provides a continuous raised surface with strong material-gripping performance. It is suitable for conveying lump ore, stone, aggregate and other bulk materials on steep inclined sections, with conveying angles of up to approximately 40° depending on material characteristics and conveyor design.
Open V Belt
The open V-shaped pattern provides moderate anti-slip performance while leaving more space between raised sections for material discharge and cleaning. It is suitable for grain, sand and small granular materials on conveying lines with approximately 15°–30° inclination.
Dotted Rough Belt
The dotted surface consists of small raised rubber points that provide gentle friction without creating excessive material retention. It is mainly used for cartons, bags, packaged goods and grain handling on low-angle conveying lines below approximately 15°.
Diamond Cross Belt
The diamond cross pattern provides balanced surface friction and lateral material stability. Its relatively open structure also facilitates surface cleaning, making it suitable for logistics sorting, light industrial products and finished goods conveying.
How Does Pattern Selection Affect Conveyor Performance?
The main selection factors are conveying angle, material characteristics, pattern height and required surface friction. A higher or more continuous pattern generally provides stronger grip, while an open or low-profile pattern can offer easier cleaning and lower material retention.
| Pattern Type | Core Characteristic | Applicable Working Condition |
|---|---|---|
| Closed Chevron | High grip and strong material retention | Lump ore, stone and aggregate steep conveying |
| Open V Pattern | Moderate anti-slip performance and easier discharge | Grain, sand and granular materials |
| Dotted Rough Pattern | Light friction and relatively easy cleaning | Cartons, bags and packaged goods |
| Diamond Cross Pattern | Balanced friction and lateral stability | Logistics and light industrial products |

Flame Retardant Anti-Static Patterned Belt
This type uses flame-retardant and conductive rubber compounds for underground conveying applications where fire and static electricity are safety concerns. Models for coal mine applications can be manufactured according to applicable MT/T668 requirements.
High Temperature Resistant Patterned Belt
High-temperature patterned belts use heat-resistant rubber compounds for conveying hot materials such as cement clinker and steel slag. YUFENG configurations can be specified for material temperatures below approximately 180°C according to the actual conveying conditions.
Oil Resistant Patterned Belt
Oil-resistant models use NBR-based cover rubber to reduce swelling and cracking caused by mineral oil, lubricants and other oil-containing materials. They are suitable for chemical plants, oil-related material handling and industrial production environments.
Low Temperature Resistant Patterned Belt
Low-temperature formulations maintain rubber flexibility in cold outdoor environments. They can be specified for applications requiring operation down to approximately -40°C, including open-pit mining and winter bulk material transportation.
Dotted Rough Pattern Logistics Belt
The low-profile dotted surface provides controlled friction for cartons, grain bags and packaged products. It is suitable for warehouse sorting and logistics conveying where excessive surface pattern height is unnecessary.
What Customization Options Are Available?

YUFENG can provide closed chevron, open V, dotted, diamond cross and other molded surface configurations according to the conveyor application.
Pattern Height
Pattern height can be selected according to conveying angle, material size and required grip. Standard options include 6 mm, 16 mm, 25 mm and 32 mm, with customized dimensions available for specific equipment.
Fabric Carcass
EP polyester fabric provides low elongation and stable dimensional performance, while NN nylon fabric offers greater flexibility and impact resistance. The appropriate carcass can be selected according to conveyor length, loading conditions and pulley diameter.
Functional Rubber Compound
The cover rubber can be modified for flame retardancy, oil resistance, high-temperature resistance, low-temperature flexibility and other operating requirements.
Bottom Surface Configuration
The bottom surface can be supplied with a smooth fabric-backed structure or rubber-backed structure according to the conveyor frame, idler arrangement and installation requirements.
How Is YUFENG Patterned Belt Manufactured?
Fabric Carcass Preparation
High-tenacity EP polyester-nylon canvas or NN nylon fabric is selected according to the required tensile grade. Fabric layers are controlled for uniform warp and weft density to maintain consistent belt tension.
Rubber Compound Preparation
Virgin natural rubber, NBR or other functional rubber compounds are selected according to the working environment. The compound is formulated to provide the required wear, adhesion, temperature or chemical resistance.
Pattern Molding and Vulcanization
The patterned working surface and belt body are integrated through high-temperature vulcanization. This structure avoids the separate adhesive bonding used by some low-quality patterned belts and reduces the risk of pattern peeling during repeated bending.
Factory Quality Inspection
Fabric and rubber materials are sampled for tensile, elongation and adhesion performance before production. Finished belts are inspected for carcass performance, cover rubber properties and pattern bonding before shipment.
What Raw Materials Does YUFENG Use?
Tensile Carcass
YUFENG uses high-tenacity EP polyester-nylon canvas or NN nylon fabric with controlled warp and weft density to provide stable tensile performance.
Pattern Cover Rubber
Virgin natural rubber, NBR and functional synthetic rubber can be selected according to wear, oil, temperature and safety requirements.
Bonding Skim Rubber
High-adhesion skim rubber is used between fabric layers and rubber compounds to improve interlayer bonding and reduce the risk of delamination under continuous loading.
Raw Material Inspection
Each batch of fabric and rubber materials undergoes factory laboratory sampling for tensile strength, elongation and adhesion before entering the vulcanization process. Materials that fail internal requirements are not released for production.
