A cone crusher is one of many different types of crushers, like impact crushers, jaw crushers, and hammermills, that is used to process and reduce material like aggregates and construction and demolition waste. The cone crusher distinguishes itself from these other crushers by how it operates in processing material.

Finally, the reliability of the optimization model and optimization algorithm of cone crusher is verified by the DEM based on the characteristics of coarse crushing ores.
First, the DEM team succeeded in developing DEM models for most comminution devices, except for the cone crusher. In 2005, the team started to focus on the development of the cone crusher model. After several rounds of brainstorming, the team scientists decided to try a novel approach: the Fast Breakage DEM algorithm.

Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation of rock materi-als. Control systems for cone crusher settings are widely used for compensating for wear and protecting the machines from high pressure. However, these systems focus on the crusher and not the crushed prod-ucts.

The speed control algorithm was tested on a HP300 cone crusher, which was operated in a closed-loop configuration during the late fall of 2007. The crushers were operated in three different modes: a fixed standard speed of 1500 rpm, a speed corresponding to the operator's choice, and a speed determined by the algorithm.
When new mantle and concave liners are installed, the automatic reminder is reset. As the crusher operates, the system tracks production capacities and calculates the liner wear rate. When the cone liners reach the maximum wear point, the system sends a flashing reminder to "Change Cone" on the cone setting meter.
This work presents an extension and validation for a control oriented model of cone crushers. Compared to earlier work, the aspect of energy consumption was added to the model. Validation was ...
A dynamic cone crusher model that describes the output size distribution (size reduction), and the flow was presented in this work. Simulations have showed that the steady-state model behavior is qualitatively consistent with measured crusher behavior, as reported in e.g. (Lee and Evertsson, 2011), in terms of response to changing the ...
Compression cone crusher designs today have evolved from the simple cone crusher first developed in the mid-1920s by Edgar B. , to the modern high performance crushers. Early crushers used springs for tramp iron protection and were manually adjusted. The newer crushers utilize a safer more reliable hydraulic tramp …
This paper describes a novel size reduction control strategy for cone crushers to address this problem. The proposed control strategy is based on self-optimizing control structure (near-maximum performance using constant setpoint) to ensure the desired degree of size reduction in a long-term production.
This work opens with a brief review of the mechanical principles of cone crushers. Then, in the following sections, works available in the cone crusher literature, ranging from 1972 to 2020, are categorized with respect to the model structure and control strategy implementation.
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 converter also the eccentric speed in a cone crusher can be adjusted in real-time in addition to the CSS.
Some works in the cone crusher control literature offer a broader perspective regarding process optimization by contemplating the cone crusher and all the ancillary equipment that comprises a crushing cir-cuit.

A case study is presented that demonstrates the application of the technique to the design of cone crusher liners. New crusher liner profiles resulting from the application of the evolutionary algorithm suggest that significant improvements in the generation of lump product can be obtained.
Cone crushers are very suitable for size reduction and shaping in the downstream of a crushing circuit. They reduce the material in a crushing cavity by continuous compression between a fixed element (bowl liner) and a moving element (mantle). Cone crushers are equipped with a hydraulic setting adjustment system, which allows adjusting the ...
