A high angle conveyor can be defined as any conveyor that transports material along a slope exceeding the dynamic stability angle of the transported material. The application of conveyors in this mine study recognises the cost savings in material haulage that a high angle conveyor has in a total system. High Angle Conveyor Principles

BELT CONVEYORS FOR BULK MATERIALS 1. INTRODUCTION: Belt conveyors consist of two powered pulleys with a continuous loop of belting material used to convey products. Belt conveyors are the most economical powered conveyor and are typically used for conveying products over long distances, at high speeds, or for incline/decline applications.

Until the 1970s, ore haulage was commonly carried out by rail haulage systems, which were then mostly superseded by technological progress in the form of trucks and conveyor belts. Trucks can be used very selectively, breakdowns involving single units can easily be accommodated, and the cost of service and maintenance of DC-electric locomotives ...

The major development, apart from self-advancing supports, allowing high production longwalls to evolve was the Armoured Face Conveyor or AFC which was originally developed in Germany and was frequently (less so nowadays) referred to as a Panzer conveyor. Essentially an AFC is a one-sided trough scraper conveyor, the second side of the ...

Apr 01, 2017 Mechanical haulage in metal mines is of four general types: (1) Locomotive, (2) scraper or slusher, (3) rope, and (4) belt conveyor. Locomotives for underground use are powered by electric, compressed-air, or, rarely, gasoline motors. Diesel locomotives have been used extensively in Europe, but have not been adopted in the United States.
