hopper conveyors required. As soon as we have determined the grasshopper length, we will then size our HIC (Horizontal Index Conveyor) based off of this. The last step would be to determine the cell width and pile height to correctly size the stacker. E&MJ; : What are some of the individual site characteristics you encounter that require additional engineering or customization? Hanson: Weather conditions in any given area will always need to be looked at. Rain, snow and wind cannot be overlooked. The valley fill sites are always more complex than a standard site. One aspect that needs to be looked at thoroughly is the power travel for all the conveyors—the HIC will need to be sized to tow the stack- er and itself up the worst incline. The radi- al travel of the stacker also must be taken into account. E&MJ; : Can prospective heap-leach cus- tomers take advantage of any recent advances in materials, control systems, energy-saving technology or other aspects of conveyor equipment design to improve the efficiency of their operation? Hanson: Our latest advance is an auto level system on our stacker. This technology allows us to keep the stacker level while moving radially on an uneven terrain. This will be very helpful in regard to belt track- ing and with material spillage. Last year, Superior updated its telescop- ing radial stacker automation program, which didn't affect the physical function of the machine but provided a user-friendly screen design featuring enhanced graphics and onscreen buttons to help operators navigate the software more easily, among a list of other improvements aimed at user convenience.
