Ep Conveyor Belt Carcass Construction Impacts The Belt Tension Ratings:
Carcass
The internal reinforcements and fabric plies provide the mechanical strength to the belt. Made up of fabrics like polyester, nylon, and cotton.
Number of Plies
More plies provide higher tensile strength to resist tension forces. Tension rating increases with more plies. 2-ply is around 400 PIW. 6-ply reaches 1200 PIW.
Ply Adhesion
Rubber coating properly bonded to fabric carcass ensures the plies work together. Poor adhesion weakens the belt strength.
Ply Thickness
Thinner but stronger fabrics allow more plies to be stacked in the same belt thickness. Increases strength without sacrificing flexibility.
Ply Orientation
Multi-ply belts with cross-oriented 0° and 90° plies provide good lateral and longitudinal stiffness. Helps under load.
Ply Material
Polyester provides the highest tensile rating per ply. Aramid fabrics offer very high strength-to-weight ratio.
Skim Coats
Skim rubber coats applied between plies help reduce internal ply friction and shear. Improves belt flexibility.
Breaker Strips
Rubber-coated fabric strips layered between plies to improve impact and flex fatigue resistance in the belt.
Belt Gauge
Total carcass thickness specified in 1/16 inch increments. More plies increase the gauge and tension rating.
Edge Sewing
The sewn fabric along belt edges helps reinforce and prevent ply separation and lifting under load.
The carcass construction and design directly influence the belt’s tension strength, capacity, and overall durability in a conveyor system.
Technical Specifications:
A ep conveyor belt is made of a blend of polyester/nylon fabric consisting of polyamide for weft and polyester for warp which makes it strong and flexible. Rubber skim coats ensure adhesion and load support, with top and bottom cover compounds for maximum protection.
Ep conveyor belts are widely used in material handling systems in manufacturing – cement, aggregate, stone crusher plant, mining, coal, and power steel industries for transporting heavy or bulky materials. They are durable, heat-resistant, and have excellent tear and abrasion resistance.

Key Ratings And Specifications For Rubber Conveyor Belting Related to Plies:
Number of Plies
Layered fabric reinforcements inside the belt carcass. More plies increase strength and load capacity. Common ply ratings are 2, 3, 4, 5.
Ply Type
Polyester and nylon are common ep conveyor belt ply fabrics. Polyester provides greater strength while nylon offers flexibility.
Ply Strength
Measured in tension strength per ply. Rubber belts typically have 400-500 lbs per ply per inch of belt width.
Overall Belt Strength
Determined by multiplying ply rating by number of plies. A 3-ply belt with 400 lb/ply/in rating has 1,200 lbs per inch belt strength.
Tension Rating
Maximum tension force the belting can withstand repeatedly without damage. Depends on number of plies.
Load Support
More plies spread load stresses over larger area providing better load support and lengthening belt life.
Flexibility
Belts with fewer plies generally trough and flex easier around pulleys. Multi-ply belts tend to be stiffer.
Fastener Suitability
A number of plies impacts splice strength and fastener grip. Thicker belts need heavy-duty fasteners.
Carcass Gauge
Ply fabric thickness. Thinner gauge fabrics allow more plies in the same belt thickness.
EP conveyor belt Applications
Coal mining
EP conveyor belts are used to transport coal in underground mines.
Construction
M24 conveyor belts are used to transport building materials.
Cement production
Heavy-duty conveyor belts are used to transport cement and other raw materials in cement plants.
Features of EP/Nylon Conveyor Belt
High Tensile Strength
The tensile strength of EP conveyor belt is generally between 800-2500 N/mm. The higher the tensile strength, the more resistant the belt is to tearing and
abrasion.
Abrasion & Wear Resistance
They are also resistant to wear, which helps them to last for a long time. EP conveyor belts can handle a wide range of temperatures, from up to 200°C, and can be used in high-temperature environments.
Low Elongation
Lakhotia ep conveyor belts are praised for their superior strength, performance and reliability. They are highly resistant to abrasive materials and able to withstand in heavy loads
