CS cones, standard solutions

Importance of concave selection

The crushing chamber is mostly determined by the concave (or outer liner) selection. We offer two to three different standard concave choices for each crusher model, and each has a specific application area.

Crusher model

Concaves are specified as extra course (EC), coarse (C) and medium coarse (MC).

Importance of mantle selection

We offer three different standard mantles: A, S and B – and the key differences are the positions of the crushing surface in relation to the contact surface of the head center. Each mantle has a specific application area, so not all mantles are available for all crusher models.

Second lower concave ring

Sandvik offers a second lower concave ring designed to match a half-worn upper concave on our CS840i, CS430 and CS440 models. The crushing chamber nip angle is maintained because the second lower concave has an adjusted profile (which takes into account the half-worn upper concave) and is cast and therefore does not alter the geometry of the crushing chamber.
