Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher. The equation proposed by Hersam includes a number of constants that are only qualitatively related to the machine and material characteristics.
For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.

The output product of a jaw crusher was studied by Olaleye, 2010, Mu et al., 2013 in terms of how it varies with ore body strength as well as using Discrete Element Modelling (DEM) techniques. A useful and trustworthy model requires an understanding of the modelling approach and the involved physics.
A jaw crusher, like that of the Table below, is set with an open circuit (no recirculation) at 2 in. to produce 60 tons per hour (tph) of crushed limestone aggregate. (a) How much of the output will pass a 1½-in. screen (i.e., minus 1½-in. material), and (b) how much of the material—percentage and tonnage—will pass the 1½-in. screen and ...

The rates are based on theoretical calculations that have been verified by practical measurements. Deviations from the average throughput rate are dependent on: material, grain size, composi
1. Introduction. Currently, in the primary crushing stage, commonly used crushers include jaw crushers and gyratory crushers. Recently, FL (2022) has introduced an eccentric roll crusher, which has gained favor in the crushing industry due to its high efficiency and energy-saving advantages. They are widely used for primary …
In a jaw crusher, the material is crushed between two plates: a static plate and a moving plate. Compression is applied by the moving plate, and the material becomes crushed. The size reduction obtained by a jaw crusher is form conditioned crushing due …
used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. The first stage of size reduction of hard and large lumps of run-of-mine (ROM) ore is to crush and reduce their size. Large scale crushing operations are generally performed by mechanically operated equipment like jaw crushers, gyratory crusher and roll crushers.
With a lab-scale jaw crusher as a test case, ... It refers to the quantity of materials processed or the quality of output materials within a given time frame. However, there is currently limited research on eccentric roller crushers, and the calculation method for productivity is unclear, failing to consider the motion characteristics between ...
