Civil Engineering. A contractor operates a rock crusher and stores the material until needed in an adjacent stockpile area. The stockpile area is unpaved, and some of the stockpiled aggregate is contaminated by the sub-grade and cannot be used. The estimated stockpile losses are shown in the Table 1. This equates to a combined loss of 8% each year.

Stockpiling - Angle of Repose for some typical products.
Belt conveyors in reclaim tunnels are the most efficient reclaim device if the material to be reclaimed is free flowing. Bucket wheel reclaimers feeding conveyor systems are limited to high capacity- reclaim or high capacity-sticky material applications. Careful analysis of alternative stockpiling and reclaiming arrangements with ...
Paving the stockpile area would reduce the losses due to contamination to about 2%. The crusher produces 250,000 tons/year at a cost of $1.50/ton. The new paving should last 10 years, and there is no salvage value. The paving will cover 4.56 acres. The previous stockpile losses will serve as sub-grade and base course for the new surfacing.
A 7-cy wheel loader will be used to load a crusher from a quarry stockpile of blasted rock (well blasted) 160 ft away. the rock has a loose unit weight of 2,750 Ib/cy. Estimate the loader production in tons based on a 45-minhour efficiency factor? There are 2 …

A new conceptual mining method called the near-face stockpile (NFS), which combines the in-pit crushing and conveying IPCC system with a pre-crusher stockpile, has recently been proposed for large open pits with sufficient pit bottom width. In the past, stockpiles mainly act as a "buffer" to improve the stability of the production system.
The estimated stockpile losses are shown in the Table 1. This equates to a combined loss of 8% each year. The contractor is considering paving the stockpile area to reduce the loss of material. Paving the stockpile area would reduce the losses due to contamination to about 2%. The crusher produces 250,000 tons/year at a cost of $1.50/ton.
The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.
Pre-crusher stockpiles are designed principally as buffers to decouple the mining and processing operations. They are usually paddock dumped or dumped over a face to form fingers by dumping haul truckloads and reclaimed by front-end loader in an ad hoc manner. In addition, they are often not built and reclaimed to completion but …
