Product Description
Metal Conveyor Belting:
Offered Metal Conveyor Belts are accessible in both polyester-nylon and nylon carcass. These belts can be composed by using grade M-24, grade N-17, grade HR, grade SHR and grade FR rubber material. In addition, offered belts are composed with uniquely mixed synthetic compounds that deliver ideal resistance to animal and vegetable oils alongside mineral. Moreover, our Conveyor Belts are intended to notify the least ensured complete thickness tensile power and various synthetic textile reinforcing piles. A nylon or polyester fabric is deployed in our belts that offer mechanically a high impact abuse and a low strength resistance.
Key Features:
- Highly oppose effect add accidental damage
- The integrated fabric has the least elongation
- Have superior adhesion construction
- Safe to fatigue against belt flexing
Dunlop Starfelx conveyor belting is available in both-all Nylon (NN) and Polyester-Nylon (EP) carcass and can be manufactured with the following cover rubber grades.
Grade M-24: Compounded from premium quality natural rubber to provide excellent resistance to cutting, gouging, tear and wear, and conforms to the maximum abrasion loss value specified for grade M in DIN 22102 of 1970 & IS: 1891 (Part-I) latest.
Grade N-17: Compounded rubber with improved flex life for moderately abrasive material conforming to the maximum abrasion loss value specified from Grade N in DIN 22102 of 1970 & IS: 1891 (Part-I) latest.
Grade HR: Specially compounded rubber capable of withstanding thermal degradation for prolonged periods and recommended for handling materials like alumina, ash, clinker, foundry sand etc. at temperatures above 65oC and up to 120oC for fines and 140oC for coarse materials, & IS: 1891 (Part-I) latest.
Grade SHR: Thoroughly proven in the field this grade has been specially formulated, using selected synthetic and natural rubber, to provide superior heat and abrasion resistance and is recommended for handling material like foundry sand, clinker, coke wharf, coke breeze and sinter having temperature over 65oC and up to 180oC for coarse and 160oC for fines.
Grade FR: The growing demand for fire resistant rubber conveyor belting was first catered to by Dunlop with grade of cover rubber. Our technologists have developed FR belting to meet any of the two following standards.
The Canadian Bureau of Mines(CBM)
Specification- Certification service for underground mining and equipment and materials, EMR, Canada- ERP/MRL-80-21 (TR) of september 1980 and
The canadian standards association specification (CSA) no. CAN/CSA-M422-M87 of 1987-Type C
Dunlop is among the few manufacturers worldwide to have received certification (No. 836) from the canadian centre for mineral and energy technology for conformation to type C of the CSA specifications including Drum Friction, Anstisatic and Flame Test requirements.
Grade OR: This cover grade with specially blended synthetic compounds is designed to give the best possible resistance to mineral, vegetable and animal oils.

SPECIALITY OF FABRIC USED IN CONVEYOR BELT
Polyester /Nylon Fabric (EP) Conveyor Belt
The construction of fabric used in this belt is polyester in wrap an nylon in Weft , which provides technically a low stretch and high impact abuse resistance .
Special Feature :
Resistance to compact : Polyester Belt greatly resist impact add accidental damage [up to ] over the impact resistance of cotton & viscous rayon belts depending upon the number of pipes .
Low Elongation : The belt with polyester Fabric has lower elongation than the belt using nylon fabric .
Resilliency for Supporting Loads: The polyester fabric beam construction and superior adhesion combine to ensure maximum resistance to fatigue from flexing of the belt carrying full loads and deep trough idlers.
Complete Moisture & Mildew Protection: The fabric permits higher adhesion of carcass. More Resistance to moisture and mildew protection than other fabric.
Nylon / Nylon Fabric (NN) Conveyor Belt
The Nylon / Nylon Conveyor belting offers maximum impact and damage resistance from carrying material .It is reasonably flexible and when used and when used as a carcass material for belt , quite suitable for transportng a variety of material such as Ore , Crushed Stones , Grains, Sand etc...
Special Features:
Exceptional shock & impact resistance : Nylon/ Nylon Fabric belt greatly resist impact and accidential da, mage depending upon the number of piles used in the belts .
Excellent Troughability & Flexibility : The polyester fabric beam construction and superior adhesion combine to ensure maximum resistance to fatigue from flexing of the belt carrying full loads and deep trough idlers.
Greater Resistance to water and Mildew : The fabric permits higher adhesion of carcass. More Resistance to moisture and mildew protection than other fabric.
Beside these , Nylon Fabric provides superior Fastner Holding ability and it's light weight enables usage of less motor power

|
7 |
Bowed belt |
For new belt this condition should disappear during break-in; in rare cases belt must be straightened or replaced; check storage & handling of belt rolls |
|
8 |
Off centre loading or poor loading |
djust chute to place load on center of belt discharge material in direction of belt travel at or near belt speed |
|
9 |
Slippage of belt pulley |
Increase tension through screw take-up add counter weight; lag drive pulley; increase arc of contact |
|
10 |
Material slippage and build-up |
Improve loading & transfer condition; install cleaning device; improve maintenance |
|
11 |
Bolt heads protruding above lagging |
Tighten bolts; replace lagging; use vulcanized on lagging |
|
12 |
Tension too high |
Increase speed; same tonnage; reduce friction with better maintenance; replace damage idlers; decrease tension by increasing arc of contact or go to lagged pulley; reduced CWT to minimum amount |
|
13 |
Skirt board improperly adjusted or wrong material |
Adjust skirt board supports to minimum 25 mm between metal & belt with gap increasing in the direction of belt travel; use skirt board rubber (not old belt) |
|
14 |
Belt spanking down under load impact |
Install cushion idlers |
|
15 |
Material hanging up in or under chute |
Improve loading to reduce spillage; install buffer; widen chute |
|
16 |
Impact of material on belt |
Reduce impact by improving chute design; install impact idlers |
|
17 |
Material trapped between belt & pulley |
Install plows or scrapers on return run ahead of tail pulley |
|
18 |
Belt edges folding up on structures |
Same corrections as for 1, 2, 3; install limit switches; provide more clearance |
|
19 |
Dirty, stuck or misaligned return rolls |
Remove accumulations; install cleaning devices; use self-cleaning return rolls; improve maintenance & lubrication; cover quality too low; replace belt with heavier cover gauge or higher quality rubber |
|
20 |

Decrease idler spacing in curve; increase curve radius |
|
27 |
Excessive forward tilt of trough rolls |
Reduce forward tilt of idlers to no more than 2 from vertical |
|
28 |
Excess gap between idler rolls |
Replace with heavier rolls |
