Embodiment Construction

[0024] figure 1 A roll crusher 1 according to an exemplary embodiment of the invention is shown. The roll crusher 1 has two substantially parallel rolls 2 arranged to rotate in opposite directions towards each other and separated by a gap. Each roller 2 has a first end 3 and a second end 4 . The roll crusher 1 comprises a flange 5 attached to the first end 3 and the second end 4 of one of the two rolls 2 of the roll crusher 1 . The flange 5 extends radially of the roll 2 and has a height H beyond the outer surface 6 of the roll sufficient to extend across a gap substantially along the nip angle α of the roll crusher 1 . The height H is sufficient to extend across the gap substantially along the nip angle α of the roll crusher 1 when the gap is set to the maximum operating gap. The flange 5 is flat and helps to keep the material to be crushed on the outer surface 6 of the roll. That is to say, due to the presence of the flange 5 material is prevented from falling on the edg...

Abstract

The invention relates to a roller crusher (1) having two generally parallel rollers (2) arranged to rotate in opposite directions, towards each other,and separated by a gap, each roller (2) having a first end (3) and a second end (4). The roller crusher (1) comprises a flange (5) attached to at least one of said ends (3, 4) of one of said rollers (2). The flange (5) extending in a radial direction of said roller (2), and has a height (H) above an outer surface (6) of said roller (2) which is sufficient to extend across said gap substantially along a nip angle (alpha) of said roller crusher (1).

Description

technical field [0001] The invention relates to a roll crusher having two substantially parallel rolls arranged to rotate in opposite directions towards each other and separated by a gap, each roll having a first end and a second end department. Background technique [0002] When crushing or grinding rock, ore, cement clinker, and other hard materials, a roll crusher may be used having two generally parallel rolls rotating in opposite directions towards each other and separated by a gap. The material to be crushed is fed into the gap by gravity or choke-fed. A type of roll crusher is known as a high pressure grinding roll or high pressure roll crusher. This roll crusher uses a crushing technique known as intergranular crushing. Here, the material to be crushed or crushed is crushed not only by the crushing surface of the roller, but also by the particles in the material to be crushed, so it is named intergranular crushing. [0003] An example of a high pressure grinding ...
