Ultimate Comparison: Jaw Crusher vs Cone Crusher
With more fines and longer, more elongated particles in the mix, jaw crushers often generate a broader variety of particle sizes. A jaw crusher's typical product gradation looks somewhat like this: * Fines (<4.75 mm or 0.19 inches): 20-30% * Medium-sized particles (4.75-19 mm or 0.19-0.75 inches): 30-40%

Primary Jaw Crusher – Everything You Need to Know
A primary jaw crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. It is used in many industries, including mining, construction, and demolition, to crush materials such as rocks, coal, and ores. A primary jaw crusher consists of two plates, one stationary and one movable, which form a V …

Assessing the energy efficiency of a jaw crusher
As an indirect jaw crushing parameter, the choke feeding intensity was also emphasized by Beloglazov and Ikonnikov [40]. As the rock comminution and energy efficiency can be defined as a function of area increment of particles in jaw crusher [41], the production of fines can be diminished by regulating the mf in the crushing chamber.
McLanahan | Best Practices for Feeding Jaw Crushers
5. Provide a well-graded feed. Another best practice for feeding Jaw Crushers is to blend the feed material ahead of the crusher to ensure a well-graded feed. This will produce steady, consistent tons per hour out of the Jaw Crusher. It will also promote inter-particle crushing to break any flat or elongated material.
Discrete element modeling for predicting breakage
PFC3D modeling of rock and jaw crusher. In order to examine the fracture behavior of the rocks and to determine the applied energy in a jaw crusher, a PFC3D model for the jaw crusher was developed. This model is based on single macro-particle simulation in a crusher, and multi-body interactions are ignored. The crushing process …
