Crushing Plant Design and Layout Considerations

extended a minimum of three belt widths past the load point. Rules for conveyor and load point design should be used for guidance only, with transfers custom-designed to suit a particular project. It goes without saying that clean plants have lower operating costs. Crushers, screens and dust-collection fans all contribute to high noise levels.

Emissions of PM, PM-10, and PM-2.5 occur from a number of operations in stone quarrying and processing. A substantial portion of these emissions consists of heavy particles that may settle out within the plant. As in other operations, crushed stone emission sources may be categorized as either process sources or fugitive dust sources.

Emission points following these process activities such as secondary and tertiary crusher and screen and recirculating conveyors would be controlled by a baghouse collector. Combination systems have higher annualized costs than full wet suppression systems, but less than fully dry systems when water is readily available.

2007 Area Source Emissions Inventory Methodology

To calculate emissions, we reviewed the processes present in permitted facilities. From this, we determined that a typical small operation has 1 crusher, 1 screen, 5 conveyors and 1 acre of stockpiles. It is further assumed that the crusher processes one half of each facility's throughput. For calculation simplicity, the crusher emission
