The size reduction process of rocks in cone crushers is one of the most important issues, particularly for the secondary and tertiary stages of crushing operations. In this study, 17 different rock types were considered for the evaluation of their size There are two main cone crusher types (Hydrocone crusher and Symons crusher), of which only the Hydrocone crusher is capable of manipulating CSS during crushing. This is performed by moving a piston supporting the main shaft (and thus the mantle) hydraulically up/down.Size reduction control in cone crushers ScienceDirect

Three main factors are identified to promote the size reduction process occurring in a cone crusher, viz. breakage modes, number of crushing zones and compression ratio. The main factors provide a possibility to a fundamental and detailed understanding of how a cone crusher operates.1. Introduction The cone crusher is widely used in industry. The fundamental working principle of the cone crusher is shown in Fig. 1 where a vertical cross-section of the crusher is considered. The concave, mantle and eccentricity together form the chamber of the cone crusher.Multi-objective planning of cone crusher chamber, output and size reduction

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 multi-objective planning model is applied to optimize the cone crusher chamber geometry, output and size reduction, which provides the basis for developing models of the latest cone crushers. These models also are applied to the crusher manufacturer’s physical prototype.Multi-objective planning of cone crusher chamber, output and size reduction

The novelty and advantage of the model is the description of the inherent potential for the interaction between crusher and rock material. The modular calculation method for prediction of cone crusher performance governs the detailed understanding of how size reduction is achieved in a crusher.The reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30°. The Gyradisc crushers have head diameters from around 900 to 2100 mm. The cone crusher is a modified gyratory crusher.

Cone crusher is a size reduction mechanical equipment which crushes the large sized limestone and dolomite particles by squeezing it between gyrating spindles. Crusher must be mounted on a frame to be coupled with the motor drive. A base frame is designed in such a way that it acts as a platform for motor and cone crusher.Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.Types of Crushers: What You Need to Know Machinery

The minimum distance between the mantle and concave is defined as the closed side setting (CSS) of the cone crusher. The CSS is easily changed online in a large variety of commercial crushers; different principles of CSS adjustment are described in (Quist, 2017).The maximum distance between the mantle and concave, on the other Choke feeding a cone crusher, whereby a head of material is maintained in the chamber, provides rock-on-rock breakage (Evertsson, 2000).
