Conveyor belt specification type panoramic comparison table: from the selection code to the industry attack

I. Specification Model Core Parameters Full Deconstruction

​Conveyor belt specification system is essentially a coding system for material mechanics and environmental resistanceThe naming rules are directly related to load limits and serviceability:

1. ​Width codeB300-B3200 (unit mm), of which more than B2000 is ultra-wideband type, dedicated to port bulk terminal, coal yard annual throughput of more than 10 million tonnes of projects.
2. ​intensity marking::
   • ​textile coreEP100-EP600 (polyester), NN100-NN600 (nylon), the number indicates the number of fibres per inch, EP400 can carry 45kg/m material impact.
   • ​steel core: ST630-ST6300, ST2500 corresponds to a longitudinal tensile strength of 2500N/mm, supporting the lifting of kilometre-deep shafts in mines.
3. ​Overlay adhesive code::
   • ​thicknessesFor example, (6+3) means top glue 6mm/bottom glue 3mm, heat-resistant type needs to be ≥(4.5+2.0).
   • ​Function levelL (general-purpose), H (wear-resistant), D (flame retardant), mandatory use of class D in underground coal mines

​personal insightThe current selection of the existence of the "cult of strength" misunderstanding - a coking plant blindly selected ST3500 conveyor belt, but due to the neglect of heat-resistant grade (T3 level) led to cover rubber cracking, life plummeted 60%.The essence of specification matching is the triangular balance of strength, elasticity, and environmental tolerance.

II. Material Structure Classification and Performance Matrix

Comparison of Skeleton Material Evolutionary Routes

Critical values for weathering resistance of overlay adhesives

• ​Heat-resistantT3 grade (150°C) requires EPDM rubber, with a lifespan improvement of 300% over styrene-butadiene rubber in hot coke conveying.
• ​Oil Resistant: When the content of nitrile rubber＞32%, the volume change of diesel soaking for 7 days＜5%
• ​food grade: FDA standards require migration of ≤10mg/dm², silicone cover layer becomes the new trend

Precision Scenario Special Requirements

​food factory: White PU tape thickness 0.8-1.2mm, Ra roughness ≤ 0.4μm anti-bacterial plaque adhesion
​Lithium battery workshop: Antistatic tape with surface resistance of 10⁶-10⁸Ω, eliminating the risk of discharge of electrode material


V. Special scenario attack programme
The Ripple Revolution in Large Incline Conveying

​herringboneInclination angle ≤ 40 °, pattern height 10 mm, conveying gangue bulk material without sliding
​fan-shaped pattern: Inclination angle ≤ 60 °, dynamic gripping force lifting 200%, alternative bucket elevator


​real time dataHuaxin Cement Plant adopts 45° fan pattern conveyor belt, which saves 37% energy and reduces maintenance cost by 55% compared with the original belt system.

Intelligent anti-tear system specifications

​Pre-embedded coil: Pitch 50mm x 50mm, breakage instantaneous trigger shutdown (response <0.1s)
​steel reinforcement: Warp wire diameter 0.6mm, 8 times higher puncture resistance


VI. Future direction of specification upgrading
Composite Reinforcement Breakthrough

​Carbon aramid hybrid belt cores: Strength/weight ratio up to 3 times that of wire rope, extended dynamic bending life 400%
​Nano Ceramic Coating: Heat resistance threshold exceeds 400°C, covering adhesive thickness can be thinned 40%

Evolution of green specification standards

​Bio-based polyurethane: Castor Oil Extract Covered Gum, Carbon Emission Reduction 76%
​Biodegradable SkeletonPLA fibre core natural decomposition rate >90%, solving the pollution of discarded belts


​Exclusive foresight: Conveyor belt specifications to be added by 2028digital twin encoding--Record full life cycle stress data through implanted RFID chips to enable preventive replacement decisions. Tests at a head miner showed that the technology reduced unplanned downtime by 701 TP3T and reduced spare parts inventory by 451 TP3T.


Ask yourself the core question.
​Q: NN200 is the same strength as EP200, how to choose?​

​Intrinsic differences in deformation control::

Nylon (NN) wet elongation is as high as 4%, the conveyor belt is easy to slip in the rainy season;
Polyester (EP) Dimensional Stability Enhancement in Hot and Humid Environments 80% for coastal high humidity ports;
​cost law: EP is 1.6 times more expensive than NN, but has a lower life cycle cost of 30% for long distance transport.


​Q: Is it compliant for food conveyor belts to have a cover rubber thickness of less than 3.0mm?​

​Groundbreaking new standards::

​New ultra-thin PU belt: FDA special approval of 0.8mm thickness (traditional minimum 3.0mm), due to molecular crosslinking density enhancement of 300%;
​verification condition: Need to pass 100,000 times of dynamic flexing test without cracking, migrant detection ≤ 0.5mg/dm²;
​application scenarioBakery cooling line has been widely used, energy saving 27% and eliminate the bacterial film breeding.


​Q: Can the ST1000 conveyor belt replace the PVG1000S?​

​The red line of underground safety cannot be crossed::

​Flame Retardant Differences: PVG1000S passes the roller friction test (surface temperature rise ≤ 325°C), ST belts do not have this certification;
​electrostatic build-up: PVG surface resistance ≤3×10⁸Ω, necessary for coal mine gas environment;
​The case for cost: Illegal use of ST belts in a mine led to static ignition of gas, resulting in a direct loss of over $200 million.
