During the operation of jaw crusher, some problems may arise, such as blockage of inlet and outlet, looseness of jaw plate and spring, damage of bearing due to excessive temperature or aging, which will lead to the failure of jaw crusher to work normally. The rolling bearing is an important part of the crusher [16]. After using crusher, bearing ...
Besides being an important item for the machine's performance, the jaw crusher's jaws are responsible for front frame and swing jaw protection. Wear generally causes loss in production due to increased crushing angle, loss of tooth profile, reduction of the CSS to compensate the possible lamellar effect, etc.
Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam (1923) proposed a method for calculating capacities using a …

Jaw Crusher: Uses a reciprocating jaw to compress and crush material against a stationary plate: Primary crushing stage, handles large, abrasive materials: Up to 1,500 mm: 50-300 mm: Moderate to high: Simple design, reliable, handles abrasive materials: Limited reduction ratio, lower capacity compared to gyratory crushers: Cone Crusher
In this study, an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have been mainly property specific.
