Geometric analysis of cone crusher liner shape
For the cone eccentric angle of 1.73 degrees and a vertical cone offset of V = 0.0305 this gives a closed side setting (CSS) of 8.6 mm and an open side setting (OSS) for the crusher of 93 mm. The eccentric throw is then 84 mm. The vertical location of the One possible and straightforward future industrial application of process data and machine learning techniques is the calculation of the optimum CSS and A review of modeling and control strategies for cone crushers

The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesn’t stay in the center of the chamber it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a1. Introduction. Cone crushers are the most widely used type of crusher in the minerals and aggregate industries, given their robustness, ability to deal with rocks with a wide range of abrasiveness, good energy efficiency as well as good control of product size [1].Creating a new cone crusher design, selecting a crusher model from a particular Simulating a laboratory-scale cone crusher in DEM using

Cone Crusher Basics Porter Group
The starting point to understanding how cone crushers work and how they can make your mine or quarry more productive. The following article covers the basics of cone crushing, including chamber structure, open-side, and closed-side settings, eccentric throw, and more.The maximum feed size is approximately 8 0% of the feed opening. The open side setting is measured when the crusher is at rest. The setting is measured either top to top, or bottom to top, depending on the tooth profile of the jaw dies. The closed side setting can be calculated by deducting the stroke from the OSS.Crusher Close Side Settings 911 Metallurgist

The importance of the right mantle and concave — SRP
To get the best out of your cone crushers, you need to balance three important factors the feed, the eccentric throw, and the closed side setting (CSS). Feed. Before you can start to optimize your crushing chamber, you must have an accurate measure of the raw materials entering the chamber. Screening and classifying your feed is, of courseThe Workspectra for the equipment modelled in this paper is in the range of 180 RPM and 450 RPM in eccentric speed and a CSS setting from 50 to and compression crushing is the mainstream crushing mode, such as jaw crushers and cone crushers (Johansson et al., 2017; Wills and Napier-Munn, 2007); where the material failure is A fundamental model of an industrial-scale jaw crusher

Cone Crusher Operating Variables 911 Metallurgist
Figures 1 through 3 indicate the effect of head angle and eccentric for horsepower consumption versus closed side setting. Figures 4 through 6 show the effects of the same variables on crusher capacity. Regardless of head angle, eccentric throw, or speed, the closed side setting had the greatest effect on capacity and horsepower.An example of the effect that crusher setting has on the product gradation is as follows: If the target crusher setting is 3/8 in. (10 mm) but the setting is not checked and it wears open to 1/2 in. (13 mm), then the end result is a 15 percent decrease in the minus 3/8-in. (10 mm) material size. This is a substantial decrease in productivity.Maximize your cone crusher productivity Pit & Quarry

The influence of liner condition on cone crusher performance
The Whiten steady-state crusher model form has been used to develop a quantitative model of 7-foot cone crushers, based on sampling surveys of production machines. By incorporating liner age (wear) and liner length as variables in the regression equations for the classification parameters, it has been possible to infer the influence of Cone crushers have a static outer mantle (concave) and precession of an inner mantle mounted on the main shaft.

McLanahan CMB Cone Crushers
Below are suggested speed guidelines for CMB Cone Crushers: Low speed: Secondary applications, after a Jaw Crusher. Medium speed: Gravel applications with coarse feed. Standard speed: Tertiary applications (0 x 1/2”) High speed: Sand applications (4m or less) Speed ranges: Smaller head diameters (48” or smaller): 750-1,200 rpm.Cone crushers are commonly used in secondary and tertiary crushing stages in comminution circuits. A multitude of factors and variables influence the performance in terms of throughput capacity, size reduction, power draw and wear.
