    the steel-cord conveyor belt

    Are there any people out there who have any success experiences with the research of impingement loading on the steel-cord conveyor belt and mechanics analysis of the belt when it is teared .Any and all suggestions will be welcome. If someone knows the information or papers about it ,please tell me where I can find it or e-mail to me!
    Thank You

    Rubber Conveyor Belts

    Tom,

    I suggest you go to the eLibrary on this website and search for your topics.

    You will find several excellent articles written by experts in this field.

    You can then go to a Library to look at the respective journals or you can order the original articles as photocopies.

    Belt Damage @ Transfers

    Tom,

    We have published on the subject of gouging (tear damage) and abrasion damage assessments for belt covers in hard rock and the application of curved chutes. We use Discrete Element Method (DEM) modeling to characterize the belt and chute liner damage.

    Conveyor Dynamics, Inc. (CDI) produced the first world wide application of curved chutes in hard rock for Palabora, South Africa in 1994. Palabora transports primary crushed copper (+200mm) ore up a 16 degree grade and runs at 4.1 m/s over a 1.1km length. We increased the 18 mm top cover belt life from a measured <3 years, using a typical rockbox transfer, to a predicted >20 years using the curved chute concept. The new chute has now been working for over 8 years. The belt has little sign of wear. Liner wear life is on the order of 35-50 million tons between liner replacements. The NPV savings on belt replacement was pulblished to be $3 million for this belt feeder transfer. The chute has passed 60x89 crusher liner plates, shovel teeth, and mine drill bits with no apparent damage to the belt.

    We have successfully applied the concept to Los Pelambres (copper ore) in Chile, East Intercourse Island (iron ore) in Australia, and many others.

    Los Pelambres is a 8700 t/h primary crushed copper ore mine with a 6m/s belt and two shallow angle downhill transfers over 3 flights totaling 12.2 km. It was commissioned in 2000. Design of the belt feeder and mainline transfers were in our scope of supply. The project was in partnership with Krupp Canada.

    East Intercourse Island, a Hamersley Iron ship loading system, transports iron ore at 8000-9000 t/h. The pressure of the ore on the impact idlers, caused large rubber hysteresis heat and melted the idler's rubber impact cover.
