The Sides of the Crusher. A cone crusher has two sides: an open side and a closed side. As the material crushes, the particles that are small enough to fit through the open side fall through the space between the mantle and the concave. As the mantle gyrates, it creates a narrow point and a wide point.

The specific sources tested at Barstow included (1) a 16- by 5-ft flat vibrating screening operation, (2) a short-head crusher, and (3) a conveyor transfer point. The

Implementation Challenges of Environmental Guidelines in ...

Implementation Challenges of Environmental Guidelines in the Stone Crusher Industry. Fugitive emissions, though a substantial contributor to air pollution of the area, have always been overlooked while preparing action plans to combat air pollution. Stone crushers are identified as one such sector with high potential for fugitive dust emissions.

AP-42 Section 11.19.2 Crushed Stone Processing and ...

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.
