Defining Crusher Run Gravel. Crusher run gravel, also known as crusher run, crush 'n run, or graded aggregate base (GAB), refers to a type of crushed stone aggregate material that provides foundational support and drainage for infrastructure projects. It typically contains a blend of stone, sand, and fines produced by crushing quarried rock.
Replacement Jaw Plate sets are available. LC-27 2.25x3in Laboratory Jaw Crusher reduces 2in (50mm) aggregate, ore, and rock materials to a product with 80% passing a No. 14 (1.4mm) sieve. Jaw opening easily adjusts down to 1mm minimum to closely control output size. The maximum throughput is approximately 50lb (22kg) per hour at 525rpm.
A certain crusher accepts a feed material having an average size of 1 9 mm and gives a product of 5 mm. The power required to crush 1 5 tonnes per hour is 7. 5 kW.

In either case, the top size of the material ends up typically in the range of 200mm to 350mm, which is good for belt conveyors and fits into most secondary crushers without causing process risks. To achieve this top size, the crusher setting is 200mm or below, depending on the rock characteristics.
Daily inspections below the crusher should be made to ensure no bridging, plugging or foreign material is under the crusher. Feeding for efficiency. Uniform distribution of feed material around the cone crusher inlet is good practice. This allows production of a consistent product as well as efficient, reliable operation of the crusher.
Estimate Jaw Crusher Capacity. Example capacity calculation of a 10″ x 20″ (250 mm x 500 mm): = 2800 x 0.25 x 0.5 x 0.5 x 225 x (1-0.2)/60 = 525 kg/hr = 13 TPD vs 300 to 420 TPD —> I can't make this work! My friend Alex the SAG Mill Expert, says this equation you picked up doesn't look right.
