The distribution of comminution product can be modelled as a bimodal distribution, ... In Fig. 1 a cross-section of a cone crusher is shown, the path of the rock is drawn as a zigzag pattern where the horizontal line describes the free fall movement when a section of the chamber is opening due to the eccentric motion of the inner mantle. When ...

An improved approach is presented to model the product particle size distribution resulting from grinding in high-pressure roll crusher with the aim to be used in standard high-pressure grinding rolls (HPGR). This approach uses different breakage distribution function parameter values for a single particle compression condition and a bed compression condition. …

The distribution of comminution product can be modelled as a bimodal distribution, (Bengtsson and Evertsson, 2008). It can be shown by analysing measured data from breakage tests or from samples taken at surveys that the frequency distribution contains a region of fines and coarser products.

(a) The number of crusher reduction stages. (b) Number of crushing machines and their connected power. (c) Circuit loadings. (d) Screen requirements. (e) Size distribution of plant output. This methodology will give more accurate results than designs using standardized capacity tables and product size distribution curves.

This fine product particle size distribution information is tracked and allows prediction of the crusher product below the sizes included explicitly in the model. Pre-processing, data analysis and visualisation for the simulations shown is performed in software developed using Workspace which is a Software Workflow System (SWS) [89] .
