Abstract
The available description of mechanics of crushing process in double toggle Blake crushers, presented in literature and applied in practice, in general, is an approximated description which usually needs verification. Wide experimental studies were carried out at a modern test stand including model crusher of Blake type, measuring and control-register system. The results enabled to formulate new approach to mechanics of crushing processes, mainly focused on: load distribution in working space, friction conditions in working space, crushing energy and verification of energy hypotheses, deformation of toggle mechanism components. The results obtained in the studies formulate the base for theoretical analysis of the mechanics of the process.
Dotychczasowy opis mechaniki procesu kruszenia w kruszarkach dwurozporowych, przedstawiany w literaturze i wykorzystywany w praktyce, jest na ogół opisem przybliżonym. Obszerne badania wykonane na nowoczesnym stanowisku badawczym zweryfikowały dotychczasowe poglądy na tę mechanikę.
