Aramid Conveyor Belt

For bulk material plants cutting operating costs, our aramid conveyor belt with aramid fibre carcass suits heavy duty transport in mines, ports and steel mills.
Lighter than steel cord belts by about 30% at equal strength, it reduces drive power. Its low rolling resistance back rubber cuts indentation rolling resistance. Both features deliver around 10% power saving for the whole conveyor system.

Product Overview

For bulk material facilities aiming to lower running costs, heavy belt weight and high power consumption are key headaches for plant managers. Our aramid conveyor belt features an aramid fibre reinforcing carcass embedded in rubber. It serves continuous heavy duty transport for mines, port yards, steel mills and chemical plants.

Built around real world energy efficiency instead of strength alone, it achieves energy savings via two core designs. For one thing, aramid fibre cuts belt weight significantly. With equal tensile strength, it is around 30 % lighter than steel cord belts, reducing drive power needs and saving roughly 10 % electricity. Besides, low rolling resistance rubber on the non carrying side lowers indentation rolling resistance against idlers. Combined, these two designs generate clear energy savings for your full conveyor system.

 

Key Features & Benefits

High Tensile Strength with Low Elongation

Aramid fibre reaches 3.6 GPa tensile strength, 5 6 times stronger than high grade steel. It offers 20% higher breaking strength than steel cord belts, with low 2.5% 4.5% breaking elongation, far better than polyester or nylon belts.

For long distance high volume conveying, low stretch cuts frequent re tension work and downtime. Our DPP series only has 0.5% elongation at 10% rated load for stable continuous operation.

Light Weight Build Delivers Proven Energy Savings

At 1.44 g/cm³, aramid is 1/5 the density of steel. Belts are 30 40% lighter than equal strength steel cord belts, lowering loads on motors, idlers and pulleys.

System power consumption drops 10 20%. For 24/7 operations, significant annual electricity savings are achieved, depending on belt length and runtime.

High Temperature Resistance & Flame Retardant Options

Aramid fibre decomposes above 500 °C and runs continuously up to 300 °C, perfect for hot coke, slag and high temp ore transport.

Our Kᵃ flame retardant cover meets safety standards with ≥30% oxygen index, fit for underground coal mines and fire risk zones.

Good Corrosion Resistance & Impact Resistant Carcass

Unlike rust prone steel cords, aramid fibre resists moisture, acid and alkali, preventing internal strength loss in harsh environments.

Its tight straight warp straight weave carcass disperses impact force against heavy lumps, resisting punctures and reducing unplanned repairs. Choose H/D grade rubber for sharp ore and rock.

Improved Flexibility & Trough ability

Around 30% thinner than traditional heavy duty belts, aramid belts fit idlers closely and support smaller drive pulleys (down from 630 mm to 500 mm) for new builds or retrofits.

At 25° incline, field results show 23.8% higher conveying efficiency and 21.9% lower energy use for steep angle bulk handling.

Long Service Life, Low Cost Routine Maintenance

Field proven service life hits 4 6 years: 2 3 times fabric core belts and over 1.5 times steel cord belts.

Only visual checks for rubber wear, edge and joint damage are required; no rust inspection for inner carcass. Maintenance costs reduce by over 60%. Match cover rubber grade to your material abrasion for longer service life.

FAQ

Q1: How does aramid conveyor belt stack up against steel cord belt on total project cost?

A: Per metre purchase cost for aramid belt is higher up front. That said, many operators see good returns over time. You get lower motor load, reduced electricity bills, fewer production stops, longer service cycles and much less maintenance work. For lines running non stop, total cost of ownership often works out more favourable long term.

Q2: Can I swap my existing steel cord belt for aramid without changing equipment?

A: Direct replacement works in most installations. Thanks to better flexibility and smaller minimum pulley size, aramid belts fit most existing idler and pulley layouts. Even so, send over your conveyor parameters: pulley dimensions, belt width, tension requirements and inclination angle. Our team will review before you place an order. Special working conditions might need minor adjustments to hardware.

Q3: Which cover rubber grade fits my material?

A: H grade is for highly abrasive, sharp lump materials. D grade is the popular all round choice for mine and port heavy duty work. L grade works well for low abrasion bulk goods. Select Kᵃ grade if you need flame retardant and anti static performance for underground sites.

Q4: Is flame retardant aramid conveyor belt okay for underground coal mine operation?

A: Yes. Our Kᵃ cover flame retardant variant passes relevant safety approvals with oxygen index ≥30%. It satisfies flame resistant and anti static requirements for underground coal mine conveying. Make sure you mention underground operating conditions in your enquiry so we configure the right rubber compound.

Q5: What continuous temperature can the aramid belt cope with?

A: Standard specification handles continuous material temperature up to 300 °C. Short term peak contact temperature can go higher. Still, prolonged exposure above 300 °C speeds up ageing of outer rubber covers. Tell us your actual material temperature range and we will match a suitable cover rubber formulation.

Sidewall Conveyor Belt Sagging Solutions QBF rubber Free Zone Base Belt Design Extends Service Life by 30%

Sidewall Conveyor Belt Sagging Solutions: QBF rubber Free Zone Base Belt Design Extends Service Life by 30%

Sep 18, 2026

According to industry statistics, up to 80% of sidewall conveyor belt failures occur due to rigidity loss–induced sagging during operation. QBF rubberaddresses this root cause with an innovative “free zone ” base belt design, significantly extending the service life of sidewall conveyor belts. What Is Belt Sagging and Why Does It Shorten Belt Life? Under heavy load, especially on the return run, the base belt often sags due to insufficient transverse rigidity. This sagging triggers a chain of serious issues: Stress concentration – Sagging causes abnormal flexing at the sidewall root as it passes over the drum, concentrating stress in a localized area. Fatigue cracking – Repeated flexing leads to fatigue cracks at the sidewall root, which can develop into through-wall damage. Baffle detachment – Vibration and deformation from sagging transfer to the baffle connection, accelerating adhesive aging and causing baffle loosening or separation. Once sidewall tearing or baffle detachment occurs, the entire sidewall conveyor belt often fails prematurely. Therefore, solving the sagging problem is the key to extending belt service life. Root Cause of Belt Sagging The core cause of sagging lies in structural deficiencies of traditional base belt designs: Insufficient transverse rigidity – Traditional base belts cannot maintain a flat profile under heavy loads or long-span conditions. Unbuffered stress transfer – The sidewall-to-base belt connection lacks a flexible transition, so abnormal sagging stress directly impacts the sidewall root. Accelerated fatigue accumulation – Repeated flexing at stress concentration points causes cracks to grow from micro to macro levels. Understanding these causes makes it clear: simply increasing sidewall thickness or changing the rubber compound is a temporary fix. The solution must start with the base belt structure. Solution: QBF rubber Free Zone Base Belt Design QBF rubber introduces a “free zone ” base belt design to directly target the root cause of sagging. How the free zone  Works Blocks stress transfer – The free zone  acts as a stress buffer, absorbing and isolating abnormal sagging stress before it reaches the sidewall root. Dissipates flexing energy – The flexible edge allows the base belt to adaptively deform as it passes over the drum, spreading concentrated flexing over a larger area. Protects sidewall and baffles – By mitigating the extra load caused by sagging, the risk of fatigue tearing at the sidewall root is greatly reduced, and the baffle adhesive layer no longer suffers excessive vibration stress. Key Advantages of the free zone  Design Advantage Result sidewall tear resistance Eliminates stress concentration points; fatigue life extended by 2–3 times Baffle detachment risk Smoother operation; significantly slower adhesive aging Overall belt service life Comprehensive service life increased by 30% or more   QBF rubber’s Free Zone Base Belt design achieves a leap from “reacting to sagging consequences” to “eliminating the root cause of sagging.” Summary: Eliminate Sagging at the Source for Longer Sidewall Belt Life The sagging problem in heavy-duty sidewall conveyor belts originates in the base belt structure. QBF rubber’s free zone  design solves this industry pain point by blocking stress transfer, dissipating flexing energy, and protecting both sidewall and baffles. If you are experiencing frequent sagging, sidewall tearing, or baffle detachment with your sidewall conveyor belt, contact QBF rubber for professional technical support and customized solutions.
