We spend a lot of time on-site with new and potential customers, understanding their operations and solving their problems. Recently our product support team visited a glass recycling plant and surveyed issues they were experiencing with conveyor belts stretching over a relatively short period of time. A stretched conveyor belt results in a lack of proper tension and this in turn causes material spillage at the head drum, the hopper becoming filled up and the material not being conveyed.

The result is a safety hazard in the workplace with material spillage on the floor and inefficient operation with lots of downtimes to unclog the hopper. The customer was also incurring additional costs due to a shortened belt lifespan and needing to purchase a replacement conveyor belt more frequently.
On inspection, our Product Support team quickly identified the problem and was able to specify a Smiley Monroe EP Multi-ply belt for the recycling plant. Smiley Monroe EP Multi-ply belts have a fabric carcass in the conveyor belt (Polyester as the warp and Polyamide as the weft). From years of experience, Smiley Monroe believes that EP is the superior carcass material and delivers the best possible characteristics for belt conveying in several bulk material handling industries including recycling. EP multi-ply belts suffer negligible elongation compared to other carcass materials on the market as well as delivering the following advantages:
· High strength in proportion to weight
· High resistance to impact
· Great flexibility
· Excellent troughability
· Not susceptible to humidity and micro-organisms
The EP Fabric carcass is combined with a wide range of top and bottom cover thicknesses and specifications - all designed for maximum belt wear life and conveying efficiency.
Ply in rubber conveyor belts refers to the layers of fabric that are embedded within the rubber to provide reinforcement and strength. These fabric layers, typically made of synthetic materials like polyester or nylon, play a crucial role in the durability and performance of the conveyor belt. Here are some of the key uses and benefits of ply in rubber conveyor belts:
The primary purpose of ply in conveyor belts is to provide tensile strength. The multiple layers of fabric help the belt withstand the tension and pressure exerted during conveying, especially when handling heavy loads or over long distances.
Ply reinforces the rubber, allowing the conveyor belt to carry heavy and bulky materials without stretching or breaking. It ensures that the belt can support the load and distribute it evenly across the width of the belt.

Ply layers enhance the tear resistance of the conveyor belt, making it less likely to be damaged or compromised when subjected to sharp or abrasive materials.
Ply helps in absorbing impact loads, preventing damage to the belt and reducing the risk of punctures or cuts.
While providing strength, the ply layers also allow the conveyor belt to flex and adapt to various pulley diameters and conveyor configurations without deformation.
Ply minimizes the elongation of the belt under load, ensuring that the belt maintains its proper length and tracking.
The reinforcement provided by ply extends the life of the conveyor belt, reducing the need for frequent replacements and maintenance.
Conveyor belts with multiple ply layers are suitable for applications that demand higher strength and durability. They are often used in mining, agriculture, and heavy industries.
For lighter-duty applications, single-ply conveyor belts with a single layer of fabric may be used. These are cost-effective and provide flexibility for specific applications.
The choice of fabric material and the number of ply layers can be tailored to meet the requirements of different industries, materials, and environments. For instance, belts used in the food industry may have specific fabric requirements to meet hygiene standards.
Depending on the fabric material used, ply can enhance the conveyor belt’s resistance to temperature extremes and exposure to certain chemicals.
When maintenance or repairs are required, understanding the ply structure of the belt helps technicians determine the appropriate solutions for issues like belt tracking or splice repairs.
In summary, ply in rubber conveyor belts is crucial for providing the necessary strength, durability, and resilience needed for various industrial applications. The choice of the number of ply layers, fabric material, and belt design depends on the specific requirements of the application and the materials being conveyed.
