4 Ways to Reduce Conveyor Belt Damage

Conveyor belts are both the most important and most expensive conveyor component. According to the Australian Bulk Handling Review, the value of iron ore is currently estimated at $120 USD or $160 AUD per tonne. Therefore, a conveyor capable of moving 5000 tonnes per hour can suffer $800,000 AUD of lost production every hour if a conveyor belt requires replacement due to avoidable damage or wear.

To help you reduce damage to your conveyor belt and the potential costly exercise of a belt replacement, we discuss below four ways to reduce belt damage.

1. Appropriate Belt Type ​​

DYAN Engineering Conveyor Belt Scraper On-site

The type of material and the environment of your conveying will greatly affect the service life of your conveyor belt as the specification of belt will wear more quickly if it isn’t suited to the application.  There are multiple grades of rubber conveyor belting, each of which have special properties that ensure their suitability.

For example, Grade A is an abrasion-resistant rubber belt, which is used to convey rough or abrasive material. If your conveyor requires the use of Grade A, but you instead installed a general-purpose N grade rubber belt you would find that the N grade belt would be more susceptible to wear from the abrasive material. Thus, the service life would be reduced and the belt will require replacement sooner than a Grade A belt.

You can read more about the type of rubber belting and their applications here.

2. Cleaning & Maintenance

DYNA Engineering Conveyor Belt Scraper On-site

Carryback (or material that remains adhered to the underside of the conveyor belt) can cause increased wear on the surface of the belt if it gets stuck to other conveyor components. The wear that carryback causes can be greater if the layer of material is left to thicken or harden over time.

To reduce carryback and the associated wear on the conveyor belt, it’s important to keep the belt as clean as possible during operation. Cleaning of the belt can be effectively achieved with the appropriate belt scraper, v-plows, spray bars and brush cleaners.

3. Impact Protection

DYNA Engineering Idler Rollers On-site

When large and heavy material impacts the conveyor belt, especially at the impact zones, damage can occur to the belt. Impact damage can include tears in the belt or, if the velocity of the impacting material is high enough, the objects can puncture holes in the belt.

Two effective methods of absorbing impact forces is the installation of impact idlers or impact beds, which are particularly important at the loading point and transfer points.

Impact beds are used in place of idlers when the impact force or velocity are especially high. They close the gap inherent in impact idler rollers designs, and thus provide more support to the belt where required which can increase the belt’s service life.

4. Prevention of Mis-tracking

DYNA Engineering DYNA-TRAC Tracking Rollers

The conveyor belt can be prone to mis-tracking for various reasons, examples include worn conveyor pulley and material build up. When the belt mis-tracks, it is prone to damage and additional wear, especially along the edge of the belt where unwanted contact with surrounding structure may occur.

Installation of tracking rollers can be an effective additional of helping to prevent belt mis-tracking and the damage that can consequently occur.

Our DYNA-TRAC® tracking rollers are an ideal option as they are self-aligning and self-adjusting, which ensures the belt maintains central alignment.

Effective Methods to Reduce Impact Damage

Impact damage to conveyor components can occur when bulk material falls from the transfer point into the impact zone below. The transfer points can often be several meters high and the impact can often involve lumps of heavy material being accelerated by gravity.  

Over time, impact zones can become damaged and require repair or replacement. For example, the belt can become worn and disfigured from over-stretching under the pressure of falling material. If the material impacts the belt at a high enough velocity it can pierce the belt and cause holes to form. These impacts can dramatically lessen the service life of your conveyor belt, which can have a costly ramification as belts are one of the most expensive conveyor components.

Impact damage can also occur to other components and structures of the conveyor system, such as the idler frames and rollers. The good news is, there are two effective methods to absorb the force of material impacts and reduce the potential damage to conveyor components.

1. Impact Idler Frames and Rollers

DYNA Engineering Idler Rollers On-site

Impact idler rollers are fitted to specifically designed impact frames which are positioned beneath the conveyor belt at the transfer point as a support system for the belt during operation.

Impact rollers are designed to absorb the impact loads, and for this reason, they are the type of idler roller we recommend using at transfer and loading points. Using impact rollers to absorb impact forces also means that the impact rollers will have a longer service life when compared to standard rollers. This is due to the fact they are designed and made more durable to meet the application.

Our idler rollers are quality assured as they are manufactured from high quality ERW tube, precision pressed bearing housings, quality double sealed bearings, and labyrinth seals.

Check out our idler rollers product page for more information on the different types of rollers we can supply.

2. Impact Beds​

DYNA Engineering Impact Beds

Impact beds are another effective method for reducing the occurrence of impact damage and are used in place of impact frames and rollers. Typically, they are installed under the belt at the impact zones to absorb the impact forces of falling material.

Impact roller sets can have noticeable gaps between the sets but impact beds offer more support as there is no gap along the horizonal plain.

DYNA Engineering Impact Beds

DYNA Impact Beds

Our DYNA-TRAC® impact beds reduce repair and maintenance time and costs in impact zones. They are available as standard, heavy duty and hybrid impact beds. Furthermore, we also offer custom impact beds, which you can discuss with our conveyor specialists.

3 Reasons to Use A DYNAFastFit® Scraper

The DYNAFastFit® scrapers are a conveyor cleaning component most suited to being fitted to the head pulley and below the material flow. Belt scrapers are designed to remove carryback material which sticks to the belt and can cause issues to the conveyor system if not removed.

The DYNAFastFit® scrapers have additional benefits when compared to a standard scraper arrangement, including those discussed below.

Safer and Easier Maintenance

Our DYNAFastFit® scraper range have a unique design feature which enables personnel to perform maintenance from outside of the conveyor chute. The retractable shaft can be easily withdrawn from the chute in one motion, allowing for out-of-chute maintenance.  Additionally, the patented bearing housings have been specially designed for quick and easy removal.

The ability for personnel to perform maintenance on the scrapers from outside of the chute removes the need for them to work in confined spaces, climb into the chute or use scaffolding. Working in these conditions, which the typical scraper requires, can be costly, time-consuming and dangerous for the workers involved.

Therefore, the unique design features of our DYNAFastFit® scrapers allow maintenance to be performed more safely and in a more timely manner, reducing down time and increasing productivity.

DYNAFastFit

Twist Lock Adjuster

Customizable

Our scrapers have a modular design, which allows for parts to be interchangeable between our range of models and types. For your convenience, the spare parts are also common across the entire scraper range.

Typically, traditional scrapers need the entire scraper replaced if the operator wishes to change the blade type. However, our scrapers are mounted on a standard track mounting system, allowing any blade type to be installed without the need to replace the scraper.

We also have a selection of adjusters available for each scraper, including Twist Lock, Pin Lock, Compression Spring, Tension Spring, Air, Water, Oil and Gravity.

The customizable design of our scrapers means they can be adapted to almost any location and style with available designs for primary, secondary, tertiary and reversing scrapers.

The 4 Most Common Conveyor Idlers

Idlers are fitted to different sections of the conveyor belt depending on the purposes of their use. There is a wide variety of idlers available; however, the four most common idlers each have particular benefits. Some of these benefits include impact absorption, support for the carry and return sides of the belt or maintaining correct tracking of the belt. 

DYNA Engineering Plain Trough Idler Roller Set

Trough Idlers​

Trough idlers are the most common type of carry idler, which are typically designed with 3 or 5 idler rollers and are fitted to the carry-side of the conveyor belt. The 5-roll idler offers more uniform cross section, resulting in a greater net carrying capacity. The 3-roll design has a centre idler roll and wing idlers on either side.

The benefit of using a trough idler is that they help to ensure the load-bearing capacity of the conveyor belt is the same along the length of the belt. With a more even distribution of load-bearing, the maximum capacity of material at the loading point won’t fall off of the belt.

DYNA Engineering Plain Flat Conveyor Idler

Flat Return Idlers​

Flat return idlers are the most common idler on the return side of a conveyor with single steel mounted on two drop brackets. Although a one roller design for flat return idlers is the most common, they are also available with two rollers.

The purpose of using a flat return idler is to support the belt from the return side to prevent stretching, sagging and failure of the belt, which increases the service life of the conveyor belt.

Impact Idlers​

Impact idlers are designed for loading areas of the belt, where belt damage is common due to the falling material and consistent impacts. Impact rollers absorb impact forces helping prevent damage to the conveyor belt, idler frame and surrounding structure from occurring. 

The key benefit of using impact idlers is the prevention of damage to the belt as belts are costly to repair and replace. Therefore, they help improve productivity and decrease maintenance costs.

DYNA Engineering Training Return Idler Roller Set

Training Return Idlers​​

Training return idlers detect belt misalignment and correct it, ensuring the belt tracks accurately at the tail end of the conveyor during operations.

If the belt misaligns and rubs against a fixed structure, the head chute or conveyor component, severe damage to the belt can occur as well as damage to anything the belt makes contact with. Therefore, using a training return idler helps to reduce belt damage and the associated repair costs to the belt, structure and components.

DYNA-TRAC® Tracking Rollers​

DYNA Engineering Tracking Roller

An effective alternative to our training return idlers are our DYNA-TRAC® tracking rollers, which are designed to minimize belt mistracking and assist in keeping the conveyor belt aligned and centred.

Our tracking rollers make constant adjustments in the belt alignment as they are self-aligning and self-adjusting with an intuitive steering mechanism. This mechanism streamlines the correct steering response based on the force applied, also helping to prevent over-correction of the belt alignment.

In summary, the four most commonly used types of idlers are trough idlers, flat return idlers, impact idlers and training return idlers.

When and Why Should You Use Ceramic Lagging?

Ceramic lagging is one of the most commonly used types of lagging applied to conveyor pulleys. It is often used in harsh conditions where abrasive material is conveyed because the ceramic is hardier and more durable than rubber lagging.

Ceramic lagging can be applied to the pulley shell as a rubber backed ceramic sheet or strip. In this case, the rubber backing is bonded to the pulley shell. Alternatively, the ceramic tiles can also be bonded directly to the shell without a rubber sheet or strip.

Common Types of Ceramic Lagging

The most common types of ceramic lagging are dimple and smooth finished ceramic. Both of these types of ceramic lagging offer a significant increase in friction and grip to the belt and can reduce belt slippage.

Dimple vs Smooth Ceramic Lagging

DYNA Engineering Conveyor Pulley and Belt On-site

Drive pulleys are usually lagged with dimple ceramic lagging because dimpled ceramic has increased friction and grip to assist in driving the conveyor belt. Non-drive pulleys can be lagged with smooth ceramic; however, this is less common.

Smooth ceramic lagging is generally used on non-drive pulleys as the need for friction is significantly reduced and unwanted friction can cause additional belt wear. The use of dimple ceramic lagging on non-drive pulleys has a high chance of causing scratching and wear to the belt when unwanted friction and slippage occurs.

General Benefits

Ceramic lagging has a greater service life because of its durability and it reduces lagging wear. The amount of coverage of ceramic on the surface of the lagging can be customized depending on the application. The amount of ceramic coverage can also increase or decrease the level of friction and grip.

Kolag Ceramic Lagging

DYNA Engineering Kolag Dimple Ceramic Conveyor Pulley Lagging

Kolag ceramic pulley lagging is one of the rubber backed ceramic lagging options we supply at DYNA Engineering. It is designed with ceramic tiles with a dimple profile which are embedded in rubber strips.

Design Features and Benefits

Dimple Profile for Reduced Belt Slippage

DYNA Engineering Kolag Ceramic Conveyor Pulley Lagging

The ceramic tiles on the Kolag ceramic lagging are designed with a dimple profile to significantly reduce slippage between the belt and drive pulley. The reduction in slippage is due to the rough ceramic face producing up to two times more coefficient of friction than rubber lagging.

With the reduction in belt slippage due to the dimple profile, the Kolag ceramic lagging is especially suitable in wet or muddy conditions where slippage is more of an issue.

Additionally, the reduction in belt slippage achieved by dimple ceramic lagging can result in improved conveyor belt life as consistent belt slippage will cause wear on the belt, regardless of the lagging type.

Wear Resistant

Kolag ceramic lagging has the general benefit of ceramic lagging, which is the improved wear-resistance. The wear-resistant design of ceramic lagging means that it will last longer in harsh conditions before replacement is necessary.

DYNA Engineering Kolag Dimple Ceramic Lagging

Embossed Rubber Lagging Design​

One of the unique design features of Kolag ceramic lagging is the “arrow-boss” design, which is an embossed rubber lagging design. This design feature achieves maximum water shedding benefits and out-performs the conventional rubber lagging in this regard.

On-Site Bonding

In addition to the reduced belt slippage and improved water shedding and wear-resistance, Kolag ceramic lagging comes with a buffed finish or optional bonding layer to enable it to be cold bonded on site.

Different Types of Idler Rollers

DYNA Engineering Conveyor Idler Rollers On-site

Idler rollers, or sometimes simply known as conveyor rollers, are cylindrical-shaped bars that run along and underneath a conveyor belt. There are many different types of idler rollers with varying functions.

Usually, idler rollers aid in the supporting of weight and impact of the materials being transported along the belt. They also assist in the smooth, continuous movement of the material along the belt.

Idler rollers can be self-aligning and assist in maintaining the belt tracking. Depending on the structure and shape of the conveyor belt, the rollers are usually positioned within a metal frame and are known as idler sets.

Customisable Idler Roller Options

Idler rollers can be manufactured to suit almost any conveyor application. Some variables include bearing brand, bearing size, diameter or series, wall thickness, seal type and material type. Different variables can be selected and customised to suit your application’s standards and specifications.

Different idler rollers are used for various processes, and some determining factors could be material type, specific gravity of the material and lump size.

DYNA Engineering Plain Idler Roller

Plain Idler Rollers

Plain rollers are the most common type of idler roller. They are used to support and shape the conveyor belt.

Plain rollers can be fitted to the load side of the belt in trough, tracking and transition frames. Additionally, they can be fitted to the return side of the belt.

Tapered idler roller can be installed on both the load or return side of the belt. They assist with conveyor belt tracking when they are installed in a tracking frame.

Rubber-Coated Idler Rollers​

The name for the rubber-coated idler roller is derived from the rubber that is vulcanised directly to the roller. Rubber-coated idler rollers are tear, impact and friction-resistant and therefore have a higher durability than non-coated idler rollers.

Rubber Disc Idler Rollers​

A rubber disk idler roller has durable rubber discs positioned at regular intervals along the roller. On the two ends of the roller, the rubber discs are bundled together to provide more support for the conveyor belt edge.

The spaced-out positioning of the rubber disks is to separate any carryback (leftover materials adhered to the belt after a scraper has performed its cleaning function). This helps to reduce material build-up on the outside of the roller, a common cause of belt mistracking.

DYNA Engineering Rubber Screw Conveyor Idler Rollers

Rubber Screw Idler Rollers​

Rubber screw idler rollers incorporate an anti-tear rubber coating in a continuous screw pattern along the roller. The screw pattern assists with the removal of material build-up on the belt and helps maintain belt-tracking.

DYNA Engineering Steel Screw Conveyor Idler Rollers

Steel Screw Idler Rollers​

Similar to the rubber screw idler rollers, the steel screw idler rollers have the same continuous screw-patterned coating along the roller. However, its component is steel instead of rubber.

The screw pattern assists with the removal of material build-up on the belt and helps maintain belt-tracking.

Steel screws have a greater scrubbing action than rubber screws, and thus steel screw idler rollers are more effective where carryback is heavy.

An example of where a steel screw idler may be effective is an application where scrapers cannot be used to clean the belt, such as a mobile plant conveyor. At a mobile plant conveyor, fitting a scraper is not possible due to insufficient room. Another example is in a folding conveyor, which may prohibit the fitting of such devices.

DYNA Engineering Idler Rollers

DYNA Engineering design our own idler rollers with lifelong durability in mind. They are manufactured using high quality ERW tube.

Precision pressed bearing housings, quality double-sealed bearings and labyrinth seals all ensure the high standard of DYNA manufactured idlers.
