Grinding applications in the production of fine powders are often concerned more with the breakdown of pre-existing aggregates than with fracture of solid particles.

Concrete aggregates are composed of geological materials such as gravel, sand and crushed rock. The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. sand). The resulting concrete can be used in its natural state or crushed, according to its use and application.

Concrete has two components; aggregate and paste. Aggregates generally are of two sizes; fine and coarse. Fine aggregates are those with particle sizes smaller than about 5mm, commonly known as sand, which can be natural or manufactured. Coarse aggregates are those with particle sizes greater than about 5mm. Gravel, crushed stone and blast

Aggregate crushing plants are important equipment for aggregate processing. Aggregate commonly is classified into two categories: fine aggregate and coarse aggregate. Fine aggregate is the materials that could pass the No.4 sieve, and most could be retained on a No. 200 sieve. Coarse aggregate is a relatively big materials …
