· Crushed stone, also called aggregate, refers to medium and coarse grain size material which is produced by man-made machinery and techniques rather than occurring naturally, such as in a riverbed or canyon. Crushed aggregate, often known as rock aggregate, is a crushed stone product that is mined. Larger stones are crushed in

Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.

Aggregate, is a broad word that describes a “granular material used in construction” (granular meaning particles that do not stick together). Typically, aggregate material is extracted from quarry sites using heavy machinery, and crushed to produce varying sizes. This can be filtered out by size to be used in various applications that we
