Stone Conveyor Belt

Stone Conveyor Belt from SHUNNAI is specially developed for stone processing lines requiring strong grip, wear resistance and stable operation in harsh environments. Through optimized PVC compounds, high-strength polyester reinforcement and special surface patterns, SHUNNAI provides reliable conveying solutions for marble, granite, tile, wood and other hard materials.

Instead of using standard industrial belts for every application, SHUNNAI evaluates working conditions including moisture, load weight, conveying speed and material characteristics to design suitable belt structures for different stone processing equipment.

Challenges in Stone Processing

Stone factories usually operate in environments with high humidity, heavy dust and continuous mechanical stress. The conveyor belt is not only responsible for transportation but also affects production efficiency, material safety and maintenance frequency.

Wet Environment Stability

Water cooling and polishing processes are common in stone production. Water mixed with stone powder can reduce friction between the belt and transported materials, causing stone slabs to shift or slide during conveying.

SHUNNAI designs surface patterns with enhanced friction capability to improve grip performance under wet conditions. The bidirectional staggered tooth structure helps maintain stable transportation even when water spray and slurry are present.

Heavy Material Support

Marble, granite and other stone materials create high impact loads during transportation. Repeated loading can cause ordinary belts to stretch, deform or lose tracking accuracy.

SHUNNAI uses multi-layer reinforcement structures combining industrial polyester fabric and durable PVC compounds. The reinforced carcass improves tensile strength and lateral stability, allowing the belt to maintain shape during long-term heavy-duty operation.

Stone Surface Protection

Finished stone products often require clean surfaces without scratches or impact marks. A rough or unsuitable belt surface may affect the appearance quality of polished stone slabs.

SHUNNAI provides different surface structures according to material requirements. The belt surface can be optimized for marble, granite, ceramic tiles and other products where stable conveying and surface protection are both important.

Performance in Wet Processing Lines

Wet grinding and polishing are among the most demanding applications in the stone industry. Conveyor belts must resist water exposure while maintaining friction performance and structural stability.

Anti-slip Structure

SHUNNAI adopts a bidirectional inverted triangular sawtooth pattern to improve contact force between belt and material. Compared with smooth surfaces, this structure provides stronger grip when transporting stone under wet conditions.

The special pattern design helps reduce material movement during inclined conveying and improves production consistency.

Water Resistance

Long-term exposure to cooling water may cause some belt materials to soften, swell or separate internally. SHUNNAI uses modified PVC formulations designed for wet processing environments.

Through water resistance testing, the belt maintains surface integrity without blistering, softening or edge delamination after continuous spray exposure.

Load Handling Capability

Stone materials are much heavier than many ordinary industrial products, requiring conveyor belts with sufficient tensile strength and structural support.

SHUNNAI stone belts use reinforced fabric layers to improve load carrying capability. The multi-layer structure helps distribute stress during transportation, reducing deformation and improving running stability.

For different equipment requirements, SHUNNAI can customize belt thickness, width, surface pattern and reinforcement structure according to customer production conditions.

Production Line Verification

Six-Month Stone Factory Test

To verify performance under real working conditions, SHUNNAI conducted continuous application testing in marble polishing workshops, granite cutting lines and tile production environments. The test covered high humidity, stone dust accumulation and heavy material transportation scenarios.

Test period: 6 consecutive months

Application environments: Marble polishing, granite cutting and ceramic tile conveying lines

Average conveying load: 15-30 kg/m²

The test results showed that stable friction performance, water resistance and lateral stability are key factors affecting stone production efficiency. These factors were used as important references during the design and manufacturing process of SHUNNAI belts.

Wear Resistance Test

Stone processing creates continuous abrasion because stone powder and sharp edges repeatedly contact the conveyor surface. A belt with insufficient wear resistance may quickly develop surface peeling, reducing production efficiency and increasing replacement frequency.

During grinding line testing, SHUNNAI belts maintained surface integrity after continuous operation. The reinforced wear layer and high-strength fabric structure reduced damage caused by repeated friction.

Compared with ordinary PVC belts, SHUNNAI designs the surface layer thickness and material formula according to stone processing conditions, helping extend service life in abrasive environments.

Tracking Stability Test

Belt deviation is a common problem in long stone conveying systems. When the belt moves sideways, stone slabs may shift, creating safety risks and affecting production rhythm.

SHUNNAI uses high-modulus polyester reinforcement layers to improve lateral rigidity. The stable structure reduces belt deformation and helps maintain alignment during continuous operation.

Application Experience

Marble Polishing Line

A marble processing plant in Fujian previously experienced frequent belt slipping during wet grinding operations. Operators needed to adjust the conveyor system several times every day because stone slabs moved during transportation.

After adopting SHUNNAI's solution with a high-friction surface structure, the production line maintained more stable conveying performance under water spray conditions. After more than six months of operation, the belt surface remained in good condition and maintenance frequency was reduced.

Granite Cutting Line

A granite processing company in Shandong required a belt capable of handling heavy stone materials and maintaining accurate tracking during angled conveying.

SHUNNAI customized the belt structure according to load requirements and equipment conditions. The reinforced carcass improved running stability, while the special surface design helped reduce material movement during transportation.

Tile Manufacturing Line

A ceramic tile manufacturer in Guangdong operated in a high humidity and high dust environment. Previous belts suffered from short service life and frequent splice problems.

After replacing the belt with SHUNNAI's water-resistant and wear-resistant solution, the production line achieved longer continuous operation with reduced maintenance requirements.
