Substantiation of parameters and efficiency of sandwich belt high angle conveyors for deep open pit mines

The article focuses on substantiation of such parameters heavy-duty sandwich belt high angle conveyors as the width to ensure operation without spillage load, and hugging pressure with regard its dependence length conveyor. It is noted that incorrect estimation these can lead redistribution forces between conveying belts increasing load applied belt. economic efficiency considered in comparison traditional conveyors. shown cost a conveyor jumps height hoist. operating costs increase almost linearly an hoisting very slightly depend angle.
