20 mm 10 mm 4.8 mm Fine Flaky aggregate are the aggregates whose least dimension is less than 3/5th of its mean dimension i.e. the mean dimension of an aggregate passing through 40 mm sieve and retained on 20 mm sieve is 40+20/2 = 30 mm. Now if the least dimension is less than18 mm (3/5 x 30 = 18 mm) then the aggregate is flaky.

Crushers, screens and dust-collection fans all contribute to high noise levels. Air-cooled lubrication systems are not only noisy, but often leak oil. Well-balanced, choke-fed crushers, dust-enclosed screens and dust collector fans with silencers can keep noise levels under control. Recirculating water can be used to cool crusher lubrication

Crusher run is a blended mix of coarse aggregate and fine aggregate. The combination of both crushed stone and stone dust creates a low void content (the amount of space or air between the pieces of rock in a mix) that is valuable in concrete construction for its compaction ability and drainage characteristics.
