Belt testing services

Belt samples tests

The conveyor belt is the most expensive single component in a conveyor system. RWE moves some 1000 Million metric tons of bulk material over an average distance of 11km by belt conveyor each year from open pit mines. This measure makes RWE the World’s biggest operator of conveyors.

To identify the most durable and economic conveyor belts, RWE has established sophisticated methods for belt testing. These tests far exceed the requirements for belt sample tests according to DIN, ISO and US-Standard. Among the standardised rubber and steel cord tests, RWE laboratories conduct extensive tests of belt properties required for heavy duty mining.

Such testing comprises the following activities:

  • a differential pressure air penetration to check if steel cables are totally penetrated by rubberto be able to eliminate early corrosion inside and along the steel cords
  • specialised bending tests in a salty atmosphere to check the durability of the cables as well as the bonding system between steel cables and core rubber
  • bonding tests between steel cord and rubber after aging the belt samples to check the ability to make reliable splicing, even after years of service

RWE has developed a continuous field measurement system which is in operation at a mine site. This system is used to monitor the energy efficiency and life of conveyor belts of various suppliers.

In a RWE collaboration with the University of Hanover, a test rig has been developed to evaluate the energy efficiency of conveyor belt materials. Such testing is vital to avoid early belt failures
