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;
Read MoreCrushing 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.
Read MoreJun 01, 2018 Crushing is at the heart of every aggregate operation. Put simply, crushing aggregate is the process of “making little ones out of big ones.” Mark Krause, managing director of North America for McLanahan Corp. , recently explained the basics of crushing

Read MoreCrushing is a science. The theory of crushing allows to describe the processes that occur in various types of crushers and calculate their main parameters for manufacturers — engine power, productivity, and the crushing forces. ... It is a time-consuming and expensive operation, used only in special cases, for example, when detecting ...
Read Morecrushing 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.

Read MoreThe 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 ...
