Crushing Plant Design and Layout Considerations

2016-2-24  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 ...

buried pipe calcstress

In a safe design all these sources of stresses and strains should be considered. Therefore engineers should consider all factors which affect all parts of a buried system including restrained, unrestrained, underground and aboveground parts. Depending of virtual anchor locations, a buried pipe may or may not include a restrained part.
