Equations of Motion – The Physics Hypertextbook
Make velocity squared the subject and we're done. v 2 = v 0 2 + 2a(s − s 0) [3]. This is the third equation of motion.Once again, the symbol s 0 [ess nought] is the initial position and s is the position some time t later. If you prefer, you may write the equation using ∆s — the change in position, displacement, or distance as the situation merits.. v 2 = v 0 2 + 2a∆s [3]

Assessing the energy efficiency of a jaw crusher
Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.

Jaw Crusher Explained
For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.

Jaw Crushers
The overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.

What Are Jaw Crushers and How Do They Work? | Oreflow
Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.

Crusher Reduction Ratio
Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.
