Rock Crushing Theory and Formula using Kick Rittinger's Law

Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: “The work done in crushing is proportional to the surface exposed by the operation;

Crushing Principle and Theory – Large Capacity double ...

Crushing Principle and Theory. Material crushing is a long-standing topic. Crushing is quite complicated. It is not only related to the nature of the material being crushed (homogeneity, hardness, density, viscosity, block shape and moisture content), but also to the selected mechanical equipment.

A New Approach to Crushing 3-Manifold Triangulations

crushing operation will always reduce the size of a triangu-lation, it might alter its topology, and so it requires a careful theoretical analysis for the settings in which it is used. The aim of this paper is to make the crushing operation more accessible to practitioners, and easier to generalise to new settings.

A New Approach to Crushing 3-Manifold Triangulations

The crushing operation of Jaco and Rubinstein is a powerful technique in algorithmic 3-manifold topology: it enabled the first practical implementations of 3-sphere recognition and prime decomposition of orientable manifolds, and it plays a prominent role in state-of-the-art algorithms for unknot recognition and testing for essential surfaces. Although the crushing operation will always reduce ...
