Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher product. These charts, curves, and tables give the percentages passing or retained on standard size screens for each given setting of the crusher.
The maximum size of particle dropping out of the crusher ( dMAX) will be determined by the maximum distance set at the bottom between the two plates ( LMAX ). The rate at which the crushed particles pass between the jaws would depend on the frequency of reversal of the moving jaw.

Manufacturers tend to use rules of thumb to de-rate crusher capacities for the treatment of highly competent ores that display high Bond crushing work indices (CWi). One such rule is the following: de-rate = (16/CWi)^0.5. However, care is required when using this rule as CWi test methods vary and simplistic approaches do not address all of …
To make sure the crusher is operating effectively and generating the required product size, critical parameters including feed rate, power consumption, and liner wear are routinely monitored.

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.

The dimensions of the crusher's feed opening play a crucial role in determining the machine's capacity. Interestingly, the size of the opening not only dictates the maximum size of the feed material it can accept but also influences the crusher's overall production rate.
Effect of Feed Rock Size Distribution on Crusher Performance. If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher …
McLanahan's Universal Jaw Crusher produces more spec material at a lower cost per ton and ensures continuous crushing action with less abrasive wear.
The primary can produce these sizes at a rate of 150 to 12 000 mtph depending on the feed characteristics of the ore, the crusher setting, crusher size and the connected power to the crusher.
Jaw Crushers typically have a reduction ratio of 6:1, which means a 30" feed will be reduced down to 5" at the smallest size. The product size can be adjusted by opening or closing the gap between the jaw dies at the smallest point. This is referred to as the …

As mentioned, the crushed particle size in sampling applications tends to be on the lower end of a crusher's output size range. When crushers are being used to make crushed product at the lower end of their range, crushing capacities are reduced (i.e. the smaller the crushed product, the lower the available feed rate).
