Abstract
A multiple roll crusher is provided for crushing of mineral material, more particularly of coal or oil sand. The multiple roll crusher includes at least three crusher rolls (1, 2, 5 1′, 2′), the rotation axes (R) of which lie in parallel to each other and horizontal or roughly horizontal. All directly neighboring crusher rolls (1, 2, 1′, 2′) have opposite directions of rotation. A connecting line (V) of the rotation axes (R) has at least one kink.

1-20. (canceled)
A multi-roll crusher for the size reduction of mineral material to be crushed, multi-roll crusher comprising:
- three crushing rolls each with crushing or cutting teeth arranged on a circumference of respective said crushing rolls, said crushing rolls having axes of rotation located parallel to one another and extending horizontally or approximately horizontally, each of said crushing rolls having an opposite direction of rotation from a directly adjacent crushing roll of said crushing rolls and a line connecting said axes of rotation has at least one kink.
A multi-roll crusher for the size reduction of mineral material to be crushed, multi-roll crusher comprising:
- a crushing roller arrangement comprising a multiplicity of crushing rolls each with crushing or cutting teeth arranged on a circumference of respective one of said crushing rolls;
- a housing defining walls adjoining said crushing rolls, said crushing rolls having axes of rotation located parallel to one another and extending horizontally or approximately horizontally, each of said crushing rolls having an opposite direction of rotation from a directly adjacent crushing roll to define one of a working gap, in which directly adjacent crushing rolls rotate in a direction drawing material from above the crushing roller arrangement to below the crushing roller arrangement or to define an idle gap in which directly adjacent crushing rolls rotate in a direction against drawing material from above the crushing roller arrangement to below the crushing roller arrangement, said crushing roller arrangement having a line connecting said axes of rotation with at least one portion connecting axes of rotation of directly adjacent crushing rolls being at an angle with respect to horizontal and an adjacent line portion connecting axes of rotation of directly adjacent crushing rolls being at an angle relative to said at least one portion.
