Whole-core conveyor belts are not necessarily better when thicker;scientific selection boosts efficient production

The performance of whole-core conveyor belts,which are core components in industrial transport,depends on multiple factors including material,structure,cover layer thickness,and usage environment,rather than just thickness.For example,in short-distance,light-load conveying scenarios,overly thick conveyor belts may become too rigid,causing misalignment or difficulties in splicing.Conversely,in high-impact,high-wear conditions,appropriately increasing the cover layer thickness can significantly extend service life.Therefore,users need to select based on actual material characteristics(such as particle size,corrosiveness),working tension,drum diameter,and other parameters.

Scientific selection should follow three principles:prioritizing safety,scene adaptability,and energy balance.From a safety perspective,in explosion-proof scenarios like coal mines, products certified by MT914-2008 standards for flame retardancy and static electricity prevention must be chosen.Their surface resistance must be≤3×10⁸Ω,and the self-extinguishing time after burning must be≤3 seconds.These indicators are unrelated to thickness but depend on material formulas(e.g., adding flame retardants to PVC cover layers or integrating rubber flame retardant components into PVG composite layers).

Scene adaptability is even more critical.In high-temperature environments(such as metallurgical plants),PVG material should be prioritized,as its rubber composite cover layer can withstand temperatures up to 120°C.Excessive thickness can instead cause cracking due to thermal expansion and contraction.In damp mine shafts,6mm thick PVG belts have better anti-mold properties compared to 10mm thick PVC products because the latter has higher moisture absorption.Additionally,when the conveying angle exceeds 16°,the friction coefficient of PVG belts (0.4-0.5) is higher than that of PVC belts of the same thickness,making thickness increase unnecessary to prevent material sliding.From an energy consumption perspective,every 2mm increase in belt thickness results in a weight increase of about 15% per unit length,raising the load on the drive system.Long-term operation will shorten motor lifespan by over 20%.

Optimizing the selection of whole-core conveyor belts is a key step in enhancing production efficiency.Users should abandon the 'thickness-centric' view and choose the most cost-effective solution through systematic consideration of safety performance, scene adaptability, and energy efficiency.
