P&Q University Lesson 8- Screening : Pit & Quarry

 · Following the primary-crushing stage, screens with two or three decks and different opening sizes separate the aggregate material into different size categories – with conveyors transporting the sized material for further crushing or stockpiling as a saleable product. Usually this screening is accomplished through dry screens.

3 Aggregate Properties

There are aggregate particle voids, and there are voids between aggregate particles. As solid as aggregate may be to the naked eye, most aggregate particles have voids, which are natural pores that are filled with air or water. These voids or pores influence the specific gravity and absorption of the aggregate materials. Figure 3-1.
