This machine conventional design, in that the swing jaw was made vertical. Later, when the Superior line was developed, a compromise between these two extremes was used in ...
What Are Jaw Crushers and How Do They Work? | Oreflow
The size of a jaw crusher is measured by the top opening of the crushing chamber. For example, a 48" x 42" jaw crusher measures 48" from one crushing jaw to another and is 42" across the width of the two crushers. The primary applications for using jaw crushers are: Crushing different kinds of ore; Reducing building rubble to pieces

THE SINGLE-TOGGLE JAW CRUSHERS. Fig. 3 is a cross section of the single-toggle crusher, as introduced by Mr. G. Dalton of H. R. Marsden & Company in about 1879. It is quite probable that this patent is not the real origin of this mechanism, but it is the earliest example known to the Authors that was developed in practical form.
McLanahan | Sampling Jaw Crushers
Sample Jaw Crushers operate in the same fashion as larger, production-oriented machines — a stationary jaw is oriented opposite a moving jaw to form a crushing chamber with a cross section in the rough shape of the letter "v". The moving jaw closes against a stationary jaw with sufficient force to fracture material, usually rock of some type.

Analysis of the Single Toggle Jaw Crusher Force Transmission
According to Chinese jaw crusher manufacturer's data [ 21 ], the PE 400 by 600 single toggle jaw crusher has 30 kW motor power and an input eccentric shaft speed of 275 rpm or 28.7979 radians per second. Assuming that the input speed is constant, the input torque is found to be 1.0417 kNm.
Cone Crushers (Parts of a Cone Crusher) Explained
Cone Crusher Cross-Section The spring cone crusher design is able to pass uncrushable materials e.g. tramp metal, through the crushing cavity by using springs. The first hydraulic cone crusher was developed in 1948 and this allowed for the opening of the crushing cavity hydraulically, instead of using springs (mechanical actuation).
