Conveyor belts are subject to longitudinal through cuts due to unwanted foreign material like sharp boulders, steel chute liners, iron objects like tooth points etc. Sometimes, edges of the belt gets damaged due to swaying of conveyor or other reasons. This can cause further damage to the steelcords and can be resolved by repairing the edges.
Types Of Repairs
Conveyor belts are scrapped because of the following reasons-
A total savings to the tune of approx. 60% to 65% can be achieved by using reconditioned / repaired belts instead of new belts on account of lower capital investment, lower inventory costs & lower interest costs.

Waidhan group impact pads are designed for loading points of conveyor belts, where a combination of high energy absorption and low friction is needed. Due to ease of installation, these impact pads replace the conveyor rollers, which eventually break or seize and act like a brake. They provide greater belt support area thereby increasing impact absorption and reducing impact on the belt.
The top cover is made of an UHMWPE (ultra high molecular weight polyethylene), which gives these impact pads a very low friction and high we are resistant top surface. The middle portion is of high-quality rubber having high resilience, which acts as a shock absorber at the loading zones of conveyors. These impact pads are manufactured with an aluminium T-type fixing system for easy installation.
Support Frame :
Support frames are designed to suit a wide range of applications for impact pad. These heavy duty/sturdy pads are fixed over an equally robust heavy duty bolted type adjustable support frame to absorb high impact load.

Impact of rocks and other heavy materials can greatly reduce the lifetime of feed hoppers. Our wear products have been providing heavy duty wear protection in the mining industry since years. These wear products not only protect against wear but also serve as impact-dampers and prevent any damage to hoppers.
Feed hoppers are exposed to heavy stress due to continuous operation of crushing, cutting, abrasion and impact of rocks and other particles. The wear strength and elasticity of rubber generate valuable benefits during the entire working cycle. Industrial activities unavoidably result in wear. Wear costs money, often lots of money. That's why it pays to tackle wear with wear resistant rubber and cut costs in nearly every application from discharge and storage chutes, to hoppers.
Plain steel backed wear rubber plates are excellent wear lining for truck boxes, feeders, chutes, hoppers, bins, and other applications subject to wear and noise. It can easily be installed with a wide range of secure and reliable fastening methods.

OTR tyre wheel chocks are wedges placed closely against HENN wheel to prevent accidental movement. Our OTR tyre wheel chocks come in 5 sizes starting from small tippers upto 240T dump trucks. They are durable, light weight and at the same time sturdy.
OTR tyre inflation cage is manufactured and supplied as per OTR Tyre sizes being handled by the customer at mining site. OTR tyre inflation cage is used for safely inflating the tyres in HENN workshop.
The group has 3 established workshops (Singrauli, Korba and Dhanbad) to retread tipper and light OTR tyres right from 7.00X16 upto 17.50X25 tyres (both radials and bias) by precure process. All the 3 workshops are geared to perform repairs from 16 inch tyres upto 57 inch tyres.
Precure or cold retreading involves vulcanisation without a mould at a temperature of 120 °C. The tyre is put together using a pre-vulcanised tread liner and non vulcanized bonding gum layer. The bond between the carcass, the bonding gum and the precured tread is created in an autoclave.
We manufacture our own retreading materials (precure tread rubber, vulcanising cement and bonding gum).Our precured tread is manufactured by using best raw materials under very high curing pressure resulting into higher mileage with longer tread life. Waidhan group, being the largest OTR tyre retreader in the country uses its own formulated tread compounds which has set new industry bench marks in India in terms of reliability and mileage for retreaded tyres. This has been achieved through unparalled experience of35 years and continuous research and development activities.
The precured tread is tailor made and formulated to suit the application and conditions for which the tyre has to be used. Each and every batch of retreading material which is being manufactured undergoes a strict quality check which ensures consistent quality and standardisation.
