The importance of the right mantle and concave

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).

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 course, a major part of any crushing operation. You can find out about the range of screens that Sandvik offer here: Stationary screens and feeders.

This measures the pendular movement of the mantle. The greater the eccentric throw, the more the mantle moves away from its axis. Matching the mantle and the eccentric throw is a crucial step to ensuring optimal output and an even wear pattern. You can find out more about eccentric throw and its importance here: What is the eccentric throw?

Once you know your feed size and eccentric throw, you can determine the right closed side setting (CSS) in order to produce the final product you want. In some cases, the CSS and eccentric throw will have to be balanced with each other simultaneously in order to achieve the right output.

Sandvik can help make sure that your cone crushers are operating with the ideal crushing chamber. Throughout our Crushing Chamber Application Guide there are look-up tables that you can use to select the right mantle, for any conceivable scenario. To truly maximize potential, Sandvik also provide computer modeling and analysis to assess the particle size distribution of your feed and determine the optimal crushing chamber setup.
