This paper presents two methods for indirect regulation of cone crusher product-size distribution: Specific energy consumption (SEC)-based control and ratio control of selected product fractions.
A novel model of cone crushers is presented that can predict the flow and the size distribution of the output as a function of the primary manipulated variables, and simulations of …
The main actuator to maintain the crusher under control is the feed setting. However, nowadays is common to find in many crushing plants variable speed drives driving conveyor belts, this extra degree of freedom provides the opportunity to improve the speed of response of the control system.
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. ...

A brief summary of Fuzzy Logic and Neural Networkprinciples is presented to provide a basis for t,~e introduction of two applications, one in Fuzzy Logic and the other utilising a Fuzzy Neural Network. The applications arepart ofa majorproject aiming to develop a new generation of fully automated control systems for Autocone cone crushers.
This material enters the primary jaw crusher sized at 24-inch minus (all material is 24-inches in diameter or less) and its output is six-inch minus, which in turn feeds a secondary cone crusher to take that material …
Then it is a task of matching the manipulated variable with a single control variable and develop an appropriate control strategy so that a stable process operation can be achieved. ...

Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of production process. In this thesis …
Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation of rock materials. Control systems for cone crusher settings are widely used to compensate for wear and to protect the machines. The eccentric speed in a cone crusher affects the number of compressions the material is exposed to and thus the particle size distribution of the product. …
The importance of accurate measurement and control of the loading level of cone crusher was shown. The review of existing measurement systems was done and their disadvantages were shown. The method of measuring loading level in the crusher based on consumed power of its engine was proposed. The factors were determined on the basis of which the task for loading …
The first two categories consist of variables that are dependent on all MVs and DVs (Evertsson, 2000). These variables can therefore provide an indication of crusher size reduction. On the other hand, the crusher state variables cannot be …
Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation of rock materials, minerals and ores. Systems used for controlling the Closed Side Setting (CSS) on cone crushers, and thereby the size reduction, are widely used to compensate for wear of the manganese crushing liners and to protect the machines from overloads. With a frequency …
The RequestUnloading method call indicates that some hauling machine requests the unloading operation. After successful confirmation, the unloading procedure starts. The ExclusionZone property describes the area that haulage machines, which are to be unloaded, are not allowed to enter when approaching the rock crusher..
