Comminution by gyratory crusher is the first stage in the size reduction operation in mineral processing. In the copper industry, these machines are widely utilized, and their reliability has become a relevant …
A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher's size is classified by:

Figure 15: Research of Single-Particle Compression Ratio and Prediction of Crushed Products and Wear on the 6-DOF Robotic Crusher
The interest and need for compressive crushing in gyratory, cone and HPGR crushers are increasing since ores become more competent and more difficult to break. Compressive crushing is energy efficient as a consequence of the crushing principle and the imposed stress-state. The stress variations can be described by stress amplitudes and it is a …

This work presents a dynamic model for prediction of flow and output size distribution of cone crushers. The main purpose of the model is for simulation of closed-loop control using the Closed Side Setting (CSS) and the eccentric speed ( ω) as manipulated variables. The idea of modeling crushers as cascaded zones is adopted throughout this …

The possibility to simulate and predict cone crusher performance is of great interest for the development of crushers as well as for the design and optimization of crushing plants.
This first part focuses on demonstrating advanced DEM/breakage prediction in crushers. Predictions for two different types of compression crusher, being a twin roll crusher and a cone crusher, and for one type of impact crusher, specifically a VSI (Vertical Shaft Impactor) are presented.
Traditional models of high pressure grinding rolls (HPGR) crushers rely heavily on survey data to make accurate predictions. In this paper, a consolidation of previous approaches of modeling comminution machines is combined with insights from crusher modeling to develop a time dynamic process model of the HPGR. The crusher …
In this paper the cone crusher, which utilizes this mechanism, is investigated using the discrete element method (DEM) and industrial scale experiments. The purpose of the work is to develop a virtual simulation environment that can be used to gain fundamental understanding regarding internal processes and operational responses.

To investigate how segregation in a cone crusher affects the power draw, a feed with a controlled segregation was created. The chosen method for creating this difference was to use two completely different materials, both by PSD and by composition. Since segregation in itself can depend on many factors, the used materials needed to be …
During the operation of a forage crusher, the common issues usually faced are shorter mean time between failures and low reliability. The hammer rotor, a critical component, is prone to fatigue fracture, hammer wear, violent vibration of the rotor system caused by uneven wear of the hammers, and other issues that reduce the machine's …

Previous investigations on cone crusher performance have been carried out by Evertsson (2000), who developed a method to model flow of rock material and the breakage. Evertsson and Lindqvist (2002) has also done some investigations on the pressure distribution and power draw in cone crushers. An alternative method for wear …

A wear model for cone crushers has been implemented, in order to predict the geometry of a worn crusher. The model was verified through measurements. Adjusting the model for good agreement of wear rate in the lower part of the crushers yields an under-prediction of wear rate in the upper part. According to plant operators and the crusher ...

To calculate the output from a cone crusher, models for size reduction and flow are needed. The interaction between these two models is quite complex as the overall size reduction in a cone crusher is a result of a repeated consecutive comminution process. The flow model is important since it describes how the rock material moves through the …
