Definitions
- the invention relates to a wear-resistant roller for use in High-pressure roller presses for crushing granular material, with one Large number of welded on the roller surface at a distance from each other and outwardly protruding stud bolts between them Form pockets to hold compressed fine-grained material.
- brittle ground material is placed in the roller gap, through the two rotatably mounted counter-rotating rollers are separated from each other, drawn in and there a pressure comminution subject.
- the so-called material bed comminution in the roll gap is also known a high-pressure roller press, in which the individual particles of the ground material drawn into the roller gap by friction in a bed, d. H. in a compressed one between the two roller surfaces Mutual filling of material when using extremely high pressure be crushed. It is understood that the roller surfaces of one exposed to extremely high loads and wear are.
- the welding the stud bolt can be simpler in terms of production technology Be carried out with the help of a so-called stud welding gun, which lifts the bolt from the workpiece via a lifting magnet, whereby a Arc arises, which melts the bolt end and the base material, after which the bolt is pressed into the molten pool.
- the stud bolts without welding filler by melting the butt surfaces and pressing connected.
- the welding of such prefabricated stud bolts is only possible with a weldable bolt material. Therefore, the service life of such stud bolts is used in the extraordinary highly stressed roller surfaces of material bed crushing roller presses limited. To increase the bolt strength is also have been proposed (DE-A-41 32 474 Fig.
- the nub bolts into matching blind holes in the roller body to press in, weld in, solder in, screw in, shrink in or firmly anchored in the roller body with another connection technology It can also be difficult to use the stud bolts in the event of wear from their blind holes and removed by new bolts replace.
- the invention is based, for high-pressure roller presses the task Pressure crushing of granular material wear-resistant rollers with for the autogenous Wear protection of suitable surface armor with stud bolts to create a high even when exposed to high pressure loads Have service life.
- Characteristic of the rolls according to the invention for use in High pressure roller presses for crushing granular good is that on the roller surface two-piece stud bolts are welded, whereby the stud bolts each from a radially inner with the roller surface well weldable bolt part and from the inner bolt part protective covering radially outer harder bolt part assembled are, which the latter consists of a hard material and integrally with the radially inner bolt part is connected.
- the radially outer bolt part can with advantage of hard metal and / or ceramic material and / or Hard welding materials exist, and it has a hardness of more than 52 HRC (Hardness test according to Rockwell C), especially greater than 58 HRC. That very hard material of the radially outer bolt part increases at the grid-armored material bed crushing roller press roller according to the invention their service life.
- the radially outer stud part can be friction-welded to the radially inner stud part or arc welding bonded be.
- the radially outer bolt part can also be made by powder metallurgy and integrally sintered onto the radially inner bolt part.
- the radially outer bolt part and the radially inner bolt part is a prefabricated unit that is then weld well to the roller surface using the radially inner bolt part leaves. Manufacturing steps such as drilling, pressing in stud bolts in holes etc. are in the surface armor according to the invention avoided.
- 1 shows a prefabricated cylindrical two-piece studded pin, before this for the surface armoring of the material bed crushing high-pressure roller press roller 2 is used.
- 2 there is the press roll from a roll base (10), with which the outer Circumferential area forming roller jacket (11) releasably connected (tensioned) is on the surface (12) of a variety of spaced 1 arranged two-part bolt of FIG. 1 is welded.
- the metallic roller shell (11) can be made of a self-contained Bandage ring consist or of individual with the roller base body (10) releasably braced segments.
- the two-piece studs can also directly on a roller body (without roller shell) be welded on.
- the prefabricated stud bolts each consist of one radially inner (lower) weldable to the roller surface (12) Bolt part (13) and from a radially inner bolt part (13) protecting covering radially outer harder bolt part (14), the latter from Hard materials exist and are integral with the radially inner pin part (13) connected is.
- the radially outer bolt part (14) can be made of hard metal and / or Ceramic material exist or z. B. also made by powder metallurgy and sintered onto the radially inner bolt part (13).
- connection technique For cohesive Connection of the radially outer bolt part (14) with the radial inner bolt part (13) can be used as a connection technique, the friction pressure welding with rotation of at least one of the stud bodies, the arc welding, can also be used in plasma arcs etc.
- the Partition surface (15) between the lower bolt part (13) and the upper bolt part (14) does not have to be parallel to the radially outer surface of the bolt lie, but it can e.g. B. similar to the lower surface (16) of the lower Bolt part (13) be conical.
- the two-part Studs of Fig. 1 are advantageously in the stud welding process welded onto the roller surface (12).
- the lifting magnet in the welding gun then lifts the two-part Studs from the roller surface (12), by means of a Drawn arc creates an arc that is the lower end of the radially inner one (lower) bolt part (13) and the roller surface (12) locally melts.
- the lifting mechanism of the stud welding gun is automatic switched off and the two-part pin by means of spring pressure the liquid weld pool is pressed, creating a homogeneous solid connection between the roller surface (12) and the stud bolt arises, which the latter due to the protective radially outer bolt part (14) larger Hardness has a long service life.
- the hard material of the radially outer Bolt part (14) has a hardness of more than 52 HRC (Hardness test according to Rockwell C), especially greater than 58 HRC.
- the height of the radially outwardly projecting from the roller surface (12) Bolt is approximately greater than 5 mm, e.g. B. 8 to 10 mm, with a bolt diameter from Z. B. 15 mm.
- Adjacent studs are like this close distance from each other by z. B. welded smaller than about 40 mm, that the spaces or pockets formed between the bolts in Area of the roller surface (12) are so narrow that in the material bed shredding operation the press roller these spaces or pockets (17) between the bolts with one and the same and pressed through Fine bed crushing resulted in fine-grained but highly compressed Are well filled in, which during the roller revolutions in these Bags remain, d. H.
