A VERTICAL SOIL CRUSHING-ENERGY METER

angle 0, a crushing energy is applied to the soil aggregate between the plates. Part of Fj must be used to overcome gravitational forces generated by the aggregate and plate mass in addition to crushing the aggregate. In contrast, the force normal to the vertical plate on pivot b, F2, reacts only to force caused by crushing action on the aggregate.

Crusher - Wikipedia

Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other. The earliest crushers were hand-held ...
