The Mechanics of Crushing: Understanding the Jaw Crusher …
The jaw crusher exerts pressure on the materials that are to be crushed, compressing them between two cones. This action breaks the materials into smaller fragments that are easier for further processing. The jaw crusher's working principle is based on the reciprocatory movement of the fixed and movable jaw plates.

Why does the channel cross-section of a river change downstream?
In the upper course, the river erodes its bed by hydraulic action and abrasion. As the river flows downstream it is joined by tributaries, increasing the volume of water, velocity and therefore its erosive power. This enables it to cut a deeper channel as it flows downstream. Downstream, the channel becomes wider as the gradient […]

However, if the onset of detonation does not occur close to the plate, the precursor shock decouples from the reaction zone and a deflagration results. For the propane–oxygen mixtures, the onset of detonation is found to occur relatively far from the perforated plate at critical conditions.
