ASC Conveyor Repairs
Is your conveyor belt worn or damaged and in need of repair? All State Conveyors highly skilled belt technicians will have the repair solutions, whether utilising mechanical fastener systems or vulcanisation methods for your damaged conveyor belt caused by gouging, slicing and cutting.
Conveyor Belt Damages
Conveyor belts are prone to various recurring damage to their covers, fabrics and carcasses. Depending on what the belt is being used for, it is important to firstly choose the best compounds, belt surface and or profile which is ‘fit for purpose’ to increase the life of your conveyor belt. This will assist to reduce the rate, type and size of damage to the belt. You should also consider pulley lagging to further protect your belt.
Heavy duty conveyed materials such as rock may cause rips, tears, cuts, gouges and scoring to your belt covers. The carcass may also be prone to prematurely being fatigued and punctured which will result in future problems. The belts themselves may also fracture and fray at the edges resulting in the narrowing of the belting with the eventual delamination or tearing of the conveyor belt.
Types of Conveyor Belt Abrasion
There are several major of types of wear and abrasion that result from material being conveyed across most industries but particularly those in the mining and quarrying sectors. These conveyors need to transport sharp heavy rock and mineral products, whose surfaces naturally gouge and slice the surface of the conveyor belt. Slurry, sand, aggregate and rubble can be just as abrasive and cause an even deletion of the belt cover by constantly scouring the surface.
In general, there are two types of abrasion occurring in belt applications.
- The most common type of wear is found with coarse particles that cause a grinding action by the belt cover being continuously in motion causing the carry surface to be rubbed and scoured. This happens readily because the belt surface is flat and even. Sharp abrasive particles being conveyed are notorious for wearing the surface and service of the belt. Basalt and similar rock types are very abrasive. This continuous grinding associated with this type of conveyor transportation causes major wear and tear by the coarse particles that are constantly moving over rollers and sliding through incline conveyor angles.
- When the conveyor system is loaded from a chute or adverse height or angle, the rock fall creates abrasion with the continuous impact of sharp and piecing rock types or other processing materials that are feeding onto the belt cover. Once the product settles on the conveyor, they will shift and roll, causing further gouging and slicing to the belt surface. The severity of the impact will also depend on what kind of product is being conveyed.
ASC Conveyor Belt Repair Options
All State Conveyors offers belt repair, spare parts and bonding applications for both the short and long-term. We look to manage your down-time and offer repairs without having to do a change out where ever possible, with hot or cold repair techniques to the belt and longer-term solutions through re-clipping and hot and cold vulcanised splices we offer a complete range of options.
Quick Repair: Repair Bands and Patches (Short Term Solutions)
Repair bands are supplied as fabric reinforced or non-reinforced bands. These range from 30mm to 400mm wide and as standard 10m rolls. They come with CN backing and are cold bonded using our recommended ContiSecur® two part adhesives. Bands and patches may be considered a short to medium term (in a few cases a long term) measure for repairing cover damage and tears that often occur. They are devised to either sustain the belt until longer-term work can be completed to get rid of the immediate damage or to delay belt replacement.
Serious Repair: Belt Splicing (Longer Term Solutions)
When the damage is too great and in order to save the existing belt, the affected section is removed and is squared off in the undamaged section at either end of the sectionalised belt. Once this is completed the damaged section is discarded and a new section is spliced in by utilising hot or cold vulcanising or if this is not suitable, a mechanical fastener. If you prefer mechanical splicing, ASC recommends covering the mechanical splice with a repair band. We believe, however, that vulcanising gives a better lasting result.
How Bad is Your Belt Abrasion Issue?
If your conveyor belt just needs repairing we are able to overhaul and repair the belt covers, splices and fabric carcasses.
