Definitions
- the invention relates to a roller for a high-pressure roller press in particular for comminution of granular material from a roller base and an the outer peripheral region forming roller shell, which is composed of individual segments is that using feather keys and tension screws are attached to the roller body.
- the invention is based, for a high-pressure roller press the task especially for comminution of granular material the roller shell being composed of individual segments is to create rollers, their segment attachment from the work zone / press zone is kept out and their working width is not is more limited by the width of the segments, the Despite their width, segments free from warping with the roller base can be clamped and assembled and exchanged in a simple manner should be.
- the roller body is at least one key for each segment assigned that does not have a rectangular cross section as usual, but the one on at least one of their longitudinal faces has undercut dovetail guide surface with a corresponding dovetail guide surface on the Interacts inside the segment.
- dovetail guide surfaces secure the segments against one Relative movement on the roller body.
- the segments when assembled by moving along a roller surface line parallel to the roll axis direction on the roll base detachably wedged.
- the dovetail guide surfaces obliquely wedge-shaped to the plane through the roller axis.
- the conical dovetail guide surfaces are wedge-like releasably clamp against each other.
- the dovetail key integrally connected to the roller body be and project from it and into a corresponding one dovetail groove built into the inside of each segment intervene, or vice versa the dovetail key be integrally connected to the inside of each segment and project from the inside of the segment and into a corresponding in dovetail groove incorporated into the surface of the roller body intervention.
- the dovetail key and the dovetail groove only on one of its longitudinal faces the obliquely wedge-shaped or conical to the roller surface line have running dovetail guide surface while the dovetail guide surface on the other longitudinal end face of feather key and groove parallel to the roll surface line or can lie to the roller axis.
- the dovetail key can and the dovetail groove too two longitudinal end faces with the dovetail guide surfaces run obliquely wedge-shaped or conical.
- the press roll according to the invention consists of a Roller base body 10, on which a roller shell is arranged, which is composed of individual segments.
- a roller shell On the roller circumference six (or e.g. eight) segments are arranged in full roll width, or - as can be seen in FIGS. 1, 3 and 4 -
- Two segments 11, 12 are arranged side by side in the axial direction be.
- Figure 1 of the front segment 11 is the front Part shown broken away to build and connect of the segments with the roller base body.
- a key is assigned to each segment, so segment 11 the feather key 13 and the segment 12 the feather key 14 the feather keys 13, 14 are integrally connected to the roller base body 10 and they jump off the flattened body surface in front.
- the feather key has on both protruding longitudinal end faces 13, just like the feather key 14, undercut dovetail guide surfaces 15, 16 on which the dovetail key into a corresponding one on the inside of each Segments 11, 12 etc. incorporated dovetail groove.
- the dovetail guide surface 15 is obliquely wedge-shaped to the plane through the roll axis or conical to a roll surface line, where the cone angle ⁇ according to FIG. 4 is approximately> 0 / ⁇ 45 ° can be. In this way it is pushed open at the front the segment 11 clamped like a wedge against the roller base body 10 and is then both in the radial direction and in the circumferential direction firmly fixed. As a mirror image of segment 11, segment 12 becomes Fixed roller body 10. After their fixation remains between the two pushed-on segments 11, 12 a parting line 17th very small width, but not the operation of the roller press disturbs.
- the other dovetail guide surface 16 is parallel to the roll surface line or to the roll axis; but it could also like the dovetail guide surface 15 and mirror image to this are also conical to the roll surface line.
- the dovetail key is on both sides of each segment 13, 14 an expansion screw running parallel to the roll axis direction arranged, i.e. there are two expansion screws 18 per segment, 18a present, these expansion screws through through holes of the segments 11, 12 are passed and the expansion screw head ends 19 and foot ends 20 in recesses on the Sunk end faces of the segments or the roller body are. Therefore, there are no protrusions on the end faces of the rollers Construction parts available, which the lateral sealing of the Roll nip would hinder the operation of the roller press.
- Roller segment attachment is the segment attachment zone in any case kept out of the press zone of the roller press, i.e. kept away from the nip.
