Conveyor Belt

The Most Desirable Ply Composition

Synthetic ply configurations are the most favourable composition for most industrial textile types outside of heavy mining. Combinations of polyester (E) warp threads should be placed in a longitudinal direction and the transverse should be comprised wefts of polyamide (P). The industry refers to this synthetic construction as EP.

At All State Conveyors, we carry a wide range of Polyester/Nylon (EP) conveyor belts, which have been proven to provide a high level of product performance and are equipped with numerous rubber cover compounds and fillers to suit your conveying task.

Steel Cord Belting

ASC can supply steel cord or wire meshed reinforced conveyor belts as shown in the below ContiTech illustration. There are some advantages associated with these belts, for example they are particularly useful for high tension situations where the belt needs to transverse long distances and carry very heavy loads typically associated with mining. The steel wire formation has limited elongation and they have a very good ability to flex and retain its shape.

However, the main disadvantage is the weight of the belt and the amount of energy taken to mechanically dive the system and would typically used in heavy mining.

The Cover Quality Does Not Always Mean A Thicker Cover

The primary purpose of the cover is its ability to resist wear and abrasion and is not necessarily governed by the cover thickness. In some cases, it is necessary to have a thicker cover especially when rock fall is being loaded against the direction of the belts running direction but this is not always the case. The top cover should not typically exceed a3~1 ratio in thickness comparison to the thinner pulley cover, which is not directly affected by the loading of rock aggregate or similar product formations, but the bottom cover must be in some way wear resistant as to travels over the support rollers and drive drum configurations.

Cover Rubber Compounds Characteristics

Covers are formulated with differing natural and formulated compounds to assist various industrial and manufacturing applications. Natural rubber, butadiene and styrenebutadiene are primary polymers used to manufacture various types and grades of industrial belting.

Cover Fabrication

Covers are fabricated to meet the desired application, always with a primary polymer and a broad ranging mixture of modifiers and fillers, which develop the foundation for the conveyor belt cover characteristics.

All State Conveyors offer high quality textile conveyor belts with numerous ‘fit for purpose’ covers made from a variety of rubber compounds combined with various fillers to provide differing protection scenarios such as: heat, fire and electrical resistance: abrasion, cut, and gouging or oil and solvent resistant which are able to suit your conveying needs.

IThe conveyor belt stands as a critical piece of equipment in quarry operations because it determines how well production runs and affects both maintenance expenses and equipment service duration. The selection of conveyor belts by many quarry owners leads to three main problems including excessive wear combined with frequent breakage and severe misalignment. The article details conveyor belt selection for quarries through complete analysis and includes maintenance cost reduction measures alongside production efficiency enhancement methods.

1. Mechanical requirements which must be met by conveyor belts used in quarries form the basis of their performance standards.

The required specification for conveyor belts working in quarries includes these particular attributes:

The transportation of stone materials results in severe wear damage to conveyor belts. Utilities of wear-resistant rubber conveyor belts extend the overall service life of the belts.

The fabric of belts fails easily from bearing sharp or heavy materials within their structure. Conveyor belts must include reinforced tear-resistant layers if you are to select such systems.

The loading points create powerful impacts during operation. Strong EP Polyurethane EP (Polyester) along with NN Nylon and Steel Cord Conveyor Belts should be considered for the application.

Because quarries endure severe environmental exposures it becomes essential to choose conveyor belts that maintain resistance against extreme temperatures and oil exposure while tolerating cold conditions and moisture.

3. Common Conveyor Belt Problems in Quarries and Solutions

(1) Excessive Conveyor Belt Wear – How to Extend Its Lifespan?

✅ Choose high-wear-resistant rubber materials (such as Kilomega's wear-resistant conveyor belts).

✅ The material drop height should be adjusted in order to minimize belt surface impacts.

✅ Sudden impact forces should be absorbed by impact rollers.

(2) The solution involves fixing frequent belt misalignment requires implementation of the following steps.

✅Values for roller and drum positioning should be adjusted to achieve precise installation.

✅ Install automatic belt tracking devices such as self-aligning rollers or tension adjustment systems.

✅Regular inspections of cleaners should occur to prevent material buildup which makes belt alignment suffer.

(3) Belt Tearing – How to Prevent It?

The use of tear-resistant protective layers should be your first step when selecting conveyor belts together with loading-point impact beds that reduce material damage and immediate inspections followed by quick repairs for small belt cracks.

4. Organizations who want long-term benefits should prioritize selecting a trustworthy conveyor belt supplier

The selection of an experienced reliable supplier becomes essential during the purchase of conveyor belts. These factors will guide your selection of the appropriate supplier:

The supplier should hold international quality certifications which include both ISO and CE.

A dependable supplier needs to show worldwide mining or quarry references from their customers.

Following purchase does the supplier offer technical assistance and help with installation along with maintenance support?

The supplier should deliver belts promptly to reduce operational delays.

Conclusion

A suitable conveyor belt selection leads to better quarry manufacturing efficiency and leads to lower operational expenses. The combination of high-wear-resistant and tear-resistant and impact-resistant conveyor belts together with proper maintenance practices results in minimized equipment downtime while increasing operational profitability.
