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.
When used in concrete, aggregate must be skid and abrasion-resistant due to the risk of abrasion in heavy-duty pavements. Different minerals used in the aggregate means that the concrete can wear or polish can occur at different rates. Harder aggregate can be used in highly abrasive conditions to prevent wear and tear.
Primary crushers are first in a typical size reduction operation. Primaries like our Mega-Slam™ horizontal shaft impactor are commonly used in the aggregates industry to handle large feed sizes.
