The purpose of this article is to present a novel mathematical-physical model for the design of a new conical-shaped centrifugal rotor for vertical shaft impact crushers (VSI's) to reduce energy consumption. Many models of flat disced centrifugal rotors have been developed, however, these models do not use mathematical-physical relations to …
The model has been tested with an industrial-scale crusher geometry, to which the simulation results presented in this paper apply. A framework has been developed for modular-based fundamental modelling, where each module has been developed separately and tested before being used in a full simulation.
Closed Circuit is defi ned as a combination of a crusher and one or more screens were all or parts of the material will pass the crusher. Over sized material will then be re-circulated to somewhere before the crusher and thereby fed to the crusher again to be re-crushed. Parts of the rock material will thereby pass the crusher more then once.

The purpose of the Rock Crusher model is to visualize ALL the work required to go from "concept to cash," not just the work of coding. Often the work required to learn precisely what to build is invisible and therefore unmanaged. A Crusher is a backlog item (or Rock, in this metaphor), that makes learning "precisely what to build" ...

A large primary crusher is, naturally, more expensive than a smaller one. Therefore, the investment cost calculations for primary crushers are compared together against the total costs of primary stages, including quarry face clearing, blasting, and drilling costs. In many cases, dump trucks transport the rock to a stationary primary crusher.
