A review of modeling and control strategies for cone crushers
The CSS is the most used manipulated variable in cone crusher control strategies. Reducing the CSS leads to more crushing and, thus, a smaller particle size distribution in the product stream. However, this reduction comes at the cost of a smaller The eccentric speed of a cone crusher can be changed by shifting pulleys on the belt drive. This is labour- and time-consuming, and is therefore not done Real-time algorithm for cone crusher control with two variables

The main objective is to investigate the impact of various crushing parameters like feed rate to jaw crusher and eccentric speed of Jaw crusher, closed side setting and throw in cone crusher.The cone crusher was equipped with a Control Techniques Unidrive SP frequency converter, which allowed step less changes of the eccentric speed of the crusher in real-time. The pulleys were configured so that the nominal net frequency, 50 Hz, which then corresponds to 1500 rpm on the motor, would give 952 rpm on the crusher’s drive Real-time algorithm for cone crusher control with two variables

Dynamic modeling and simulation of cone crushing circuits
The cone crusher has two manipulated variables (MVs) that can be arbitrarily changed during operation: closed side setting (CSS) and eccentric speed (ES). The CSS is defined as the shortest distance between crushing liners. Other parameters affecting crusher operation are the stroke length and the crushing cavity geometry.This research involves the optimization of aggregate production using the Taguchi approach to maximize the production rate of Gneiss stone. The L18 orthogonal array has been used to investigate how the CSS, throw, eccentric speed, and particle size affect the products of the cone of the crusher (its cumulative weight fraction).

Cone crusher performance evaluation using DEM simulations
The laboratory crusher is a Morgårdshammar B90 cone crusher that has been equipped with custom machined liners, variable speed drive and a National Instruments data acquisition system. The results provide novel insight regarding the stochastic flow behaviour of particles when exited by the mantle at high frequency.The flow model is important since it describes how the rock material moves through the crusher chamber. Thereby the flow model provides input to the size reduction model. In turn, the size reduction model predicts the size distribution after compressing the rock material. Previously presented flow models have only in a simplified way describedModelling of flow in cone crushers ScienceDirect
