Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.Ability to work harden while crushing, which extends its wear life dramatically. • •u Liners work hardens by compressive forces and at any given time the work hardened face is only about 2-3mm. • • The speed at which the liner work hardens increases as the percentage manganese content increases so12-14 work hardens slowest 20-24.
