TNT’s systems are capable of conveying and continuously stacking ore, overburden, or dry tailings in both retreat and advance stacking configurations. Within these systems, the Ramp Portables are designed to operate on an inclined grade up to a 10° slope and move up ramps and over crests. Each of these units has head and tail articulation for accurate transfers of material.
Using TNT equipment to combine in-pit crushing and conveying with advance stacking on a dump or pit backfill allows overburden to be removed from a pit and stacked more economically than with trucks or traditional spreader systems.
A mobile crusher operating in a multiple-bench pit can feed a mobile Horizontal Conveyor with full-length receiving hopper. From here, material can be conveyed via Ramp Portables or via up-bench conveyors (each with Super Portable® technology) out of the pit and onto an overland conveying network. This network would convey the material to the processing plant or to the overburden stacking area.
Identical Super Portable conveyors can be used in the pit for removing shoveled material and in the stacking line for stacking overburden. This minimizes the required spare components and reduces the warehousing needs of mine maintenance.
