Crushing Plant Design and Layout Considerations

2016-2-24  There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties. These can include the owner’s engineering staff, safety personnel, operations and maintenance personnel, equipment manufacturers, and the engineering consultant. Ideally, the consultant combines his knowledge and experience with an understanding of all parties’ needs, to provide a balanced, workable, safe and economic plant design.

The provisions contained in this guide apply to the following kinds of buried pipe:

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.

Efemçukuru Mine – Underground Crushing Station

Our design entailed an underground crushing chamber with dual ore passes and an associated material handling system. At the top, heavy duty grizzlies and rock breaker arrangements accept the run-of-mine ore from production operations, while discharge chutes at the bottom—complete with Ross Feeders—supply the main vibrating grizzly feeder.

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 ...
