The purpose of this article is to obtain a comprehensive mathematical description of the kinematics of a double-toggle jaw crusher. The driving mechanism of the crusher is modeled as a planar six bar linkage. Two closed position vector loops that characterize the configuration of the mechanism are used to derive expressions for the angular position, velocity and acceleration of the moveable jaw. Dimensional data of a typical double-toggle jaw crusher are used in the derived mathematical expressions to demonstrate their application. Moreover, starting with the equation for the angular velocity ratio of the moveable jaw, with respect to the input crank, an expression for the ideal mechanical advantage of the crusher is derived. The expressions derived in this paper provide the foundation for further investigations into the mechanics and the design of the double-toggle jaw crusher.

“…His research led him to the conclusion that the forces exerted in the crushing chamber throughout the process of crushing vary depending on the region of the jaw involved. Deriving the position, velocity, and acceleration equations of any given point of the jaw crusher was of interest to Oduori et al [6]. The researchers reached the conclusion that the toggle plate configuration of the single toggle jaw crusher could be represented in a planar kinematic model as a consequence of their investigations.…”

The design and development of a new generation high crushing capacity jaw crusher, developed for the first time in Turkey and whose Closed Side Settings (CSS) may be automatically adjusted hydraulically, were investigated in this study. The calculations for the crusher developed for this purpose were included in the paper. The design modifications made to expand the crusher's jaw stroke from 27 mm to 40 mm were documented, and the capacity increase resulting from this was theoretically calculated and proven by a wide range of field tests conducted after the jaw crusher was manufactured. Field testing and their findings were also thoroughly covered in the paper. The forces on the crusher jaw and bearings, the crusher body geometry and crusher material (via fatigue analysis), and the dynamic performance of the system (via vibration analysis of the carrier system) were examined as the outcome of the FEM (Finite Element Method) and DEM (Discrete Element Method) analyses performed after the theoretical calculations. With improvements made based on the findings gained, the theoretical and practical harmony of the created jaw crusher system was realized. Field testing has proven that the adjustment procedure takes no more than 3 minutes and requires no human participation. As a result of this research, a patent application for the created automation algorithm was filed.
