Crushing Plant Design and Layout Considerations

The life of the mine is a key element in the design of any crushing plant. Short-term mine lives (three to eight years) require a very careful approach to design, layout and construction. Since the crushing plant’s structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize ...
