A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the ...

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.
hammers and screen bars, it is practical for crushing the less abrasive materials such as pure limestone and coal. Attrition crushing is most useful in the following circumstances: • when material is friable or not too abrasive • when a closed-circuit system is not desirable to control top size Shear Shear consists of a trimming or cleaving
