The moveable jaw connected to the shaft is, therefore, starts to move and exhibit a reciprocating motion. The moveable jaw moves approximately 250-400 times per minute. The material inserted between the two jaws of the jaw crusher is, therefore, subjected to a significant amount of compression force.
The complex motion jaw crusher is a concrete application of four-bar mechanism, so the transmission angle decide the efficiency of the jaw crusher. If the transmission angle is small, the efficiency of jaw crusher will be poor. So the transmission angle should be constrained to ensure the efficiency of crusher.

Jaw Crusher Parameters Stroke (LT) Minimum and maximum movability of the lower end of the jaw. This is equal to the OSS minus the CSS. R: Size reduction ratio The ratio of the gape width to the near side jaw opening. This ratio may vary from 1/3 to 1/9, but is generally 1/3 for primary crushers and 1/4 for secondary crushers. θ: Nip angle
Analysis of the single toggle jaw crusher kinematics. May 05, 2015 – This paper aims to obtain equations that can be used to describe the motion of any given point in the swing jaw of a single toggle jaw crusher., – The swing jaw drive mechanism of a single toggle jaw crusher is modelled as a planar crank and rocker mechanism with the swing jaw as the coupler link.
The swing jaw undergoes two types of motion: one is a swing motion toward the opposite chamber side (called a stationary jaw die due to the action of a toggle plate), and the second is a vertical movement due to the rotation of the eccentric. These combined motions compress and push the material through the crushing chamber at a predetermined size.
It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4-ft by 8-ft screen would be acceptable. The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft. The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft.
equation for the mechanism, equations of the position, velocity and acceleration of any given point in the swing jaw are obtained. Application of the kinematical equations that were obtained is demonstrated using the dimensional data of a practical single toggle jaw crusher. Thus, Findings: a description of the kinematics of any given point

This form works out volume of one motion of the jaw, multiplies by RPM then multiplies again by 60 to give volume/hour. This looks better, but it still doesn't work. Example, C80 jaw crusher, 2″ CSS: Q = 0.8* (0.05+0.025)*0.025*cot (10°)*1.75*350*60 = 111 m³/h (I have to guess the throw, the catalogue doesn't say)
