The cone crusher is a modified gyratory crusher. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone Figure 8.2. Power is transmitted from the source to the countershaft to a V-belt or direct drive.
Cone Crushers The cone crusher design concept is an effective and smart way of realizing compressive crushing Why cone crushers Mechanical mineral liberation - mining Aggregate production - quarries Should the crusher be the same
The chief difference between cone and gyratory or jaw crushers is the nearly parallel arrangement of the mantle and the cone at the discharge end in the cone crusher. This is illustrated in Figure 5.2. Reduction ratios in the following ranges are common for cone crushers 61 - 81 for secondaries 41 - 61 for tertiary and quaternary crushing.

We validated the predicted energy consumption during breakage with experimental data from a PYGB1821 cone crusher which was consistent with the measured results. Finally, we provide an explanation of the influence of operating parameters and structural parameters on compressive pressure and displacement as well as energy consumption.
During the sand-making process, the wear of the split cone will affect the dynamic balance of the rotor and the sand-making effect of the crusher. This paper focuses on experiments and simulations with the rotor of a vertical shaft impact crusher. A wear model for predicting the wear value of the split cone is established and its effectiveness is verified. The orthogonal test of svg xmlns ...

Apr 01, 2013 Other parameters affecting crusher operation are the stroke length and the crushing cavity geometry. Both of these can be changed, but not while operating, and are thus constants in this work. Moreover, the cone crusher is subject to a number of DVs Evertsson, 2000, Ruuskanen, 2006, Bearman and Briggs, 1998. These variables are listed in Fig. 3.
Jan 01, 1990 The broken product for each sizeenergy combination is collected and screened to determine a size distribution..Cone crusher performance 109 A key concept in analysing data from the pendulum test, and in constructing breakage functions, is that the product size distributions can be represented by a family of curves with a single parameter, tlo.
Dec 10, 2004 Recall that the values for , m and l for short head cone crushers Eqs. , 3 Results and discussion, , are most often fixed to be 0.2, 0.5 and 2.5, respectively. A higher value for the fines fraction in our case reflects the well-known fact that impact crushers produce more fines than cone or jaw crushers.
Apr 28, 2017 Providing better crusher feed control for the cone crusher through the use of surge piles, hoppers and variable-speed feeding devices such as belt conveyors or vibrating pan feeders can easily increase crusher productivity by a minimum of 10 percent.
