Cone Crushers McLanahan

Cone Crusher Applications. A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5

Crusher Reduction Ratio - Mineral Processing Metallurgy

2016-1-12  Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

TECHNICAL NOTES 5 CRUSHERS - mineraltech

2009-7-30  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: 6:1 - 8:1 for secondaries 4:1 - 6:1 for tertiary and quaternary crushing.

What affects cone crusher performance? — SRP

Any fluctuation in pressure means that the optimal force will not be delivered consistently so, of course, crusher performance declines. These are the two main causes of sub-optimal crushing performance, but losses in the reduction ratio can also be caused by selecting the wrong mantle or by having a poor chamber profile or design.

Cone Crusher - an overview ScienceDirect Topics

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.
