Modelling energy and size distribution in cone crushers ...

2019-8-1  This paper aims to show how the particle size distribution and the energy model is modelled for a Sandvik Hydrocone crusher using the work by Evertsson, 2000, Lindqvist, 2005, see Fig. 1. The paper will also show validation data for a full-scale simulation. In the full-scale model, the energy losses in bearings and transmissions are calculated ...

Gyratory Crusher - an overview ScienceDirect Topics

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are ...
