Definitions
- the invention relates to a two-roll crusher with rotatably mounted in a crusher housing, motor-driven counter-rotating rollers whose
- Central longitudinal axes are directed parallel to each other, wherein crushing teeth are arranged on the mantle of the rollers, which protrude beyond the lateral surfaces, wherein each between the free end of each tooth of a roller and the opposite shell of the other roller, a small gap is formed, wherein the crushing teeth in Circumferential direction of the rollers are arranged in rows and each row of crushing teeth of the first roller of a row of crushing teeth of the second roller is axially adjacent.
- Such two-roll crushers are known in the art and find particular in the field of
- Rollers are usually parallel to each other and aligned horizontally.
- the direction of rotation of the two rollers is in opposite directions and in such a way that the usually fed above the nip crushing material is retracted by rotation of the rollers in the nip and through the
- the main aim of all these two-roll crushers is to crush the rough feed as effectively as possible and to convert it into smaller, uniformly distributed grain fractions.
- the output material should thereby be able to be produced as economically as possible and at the same time a high quality, i. the best possible, for each
- the crushing ratio is also a
- the feed material can vary, for example, in size and the crushing can be done during the crushing process without breaking the crushed material to the target grain size.
- known two-roll crushers are the
- Two-roll crushers are one on each roll
- teeth are responsible for the crushing of smaller feed material.
- Two-roll crusher to be arranged one behind the other to obtain the desired target grain size.
- Two-roll crushers is about 1: 3 to 1: 4. Furthermore, it is in known solutions with
- Such a two-roll crusher has proven itself, but in this case it is absolutely necessary to carry out the synchronization of the rotational movement of both rolls in order to avoid a collision between the tooth and the cavity or tooth and the lateral surface of the other roll.
- the present invention has the object
- the invention proposes that are arranged on the mantle of the roller Brech leopard myselfn with different tooth height, wherein the distance between the lateral surfaces of the rollers is slightly larger than the height of the lowest height
- each crushing tooth having teeth, each crushing tooth with
- Shredding ratios of far greater than 1: 4 can be achieved.
- the rollers can be driven in opposite directions by a motor without synchronization, so that a synchronization gear, which on the one hand high costs and on the other hand requires increased maintenance can be dispensed with. Furthermore, it is possible, if desired or if necessary, for example, for cleaning purposes, the rollers in different
- rollers As a result, in particular an increased cleaning effect is given. It is also possible, the rollers
- the invention proposes that on the
- each row of teeth of a roller engages in an oppositely on the other roller circumferentially formed groove, wherein the distances between the free end of each tooth and groove bottom of this groove are the same size or similar.
- each row of teeth is a first roller
- Diameter the possibility to dip in front of the tooth in the depression, then pulled by the tooth in the gap between the tooth and groove and there to be crushed to the target grain size.
- teeth interconnecting increased tooth back can especially with teeth with teeth with teeth with teeth with teeth with teeth with teeth with teeth with teeth
- the legs of the circumferential groove to the free outer side are formed diverging, the tooth shape of the teeth having a greater height is adapted to the groove shape of this groove, that the distance between legs of the groove and
- Tooth side wall is the same size or the same size as the distance between the free end of each tooth and groove bottom.
- Shaft teeth have a rupture-tooth-like shape or have crusher teeth, and the wave troughs form the grooves, wherein during the opposite rotation of the rollers in each case a rupture-like wave tip or formed on a shaft tip crushing tooth of a roller dives into a trough of the other roller, wherein the distance gap between
- Segments is formed, which are individually solvable and fastened on or on the roller.
- FIG. 1 shows a first exemplary embodiment of a device according to the invention
- Figure is a perspective view of a
- Crusher roller pair in the working position
- Figure 3 is a segment of a
- Crusher roller mantle
- Figure 5 shows the section AA of Figure 4.
- FIG. 6 shows the section BB from FIG. 4
- FIG. 7 shows the section CC from FIG. 4
- crusher rolls are 1,2 or
- Crusher roller pairs 1,2 of a two-roll crusher shown.
- these crusher roller pairs 1,2 are rotatably mounted in a crusher housing of a two-roll crusher and thereby driven in opposite directions by a motor.
- the central longitudinal axes of the rollers 1,2 are directed parallel to each other and on the shell 3 of the rollers 1,2 Brechzähne 4 are arranged.
- the crushing teeth 4 project in each case over the lateral surfaces 3. In each case, a small clearance gap is formed between the free end of each tooth 4 of a roller 1,2 and the opposite shell 3 of the other roller 1,2.
- the crushing teeth 4 are in the circumferential direction of the rollers 1,2 in rows on the jacket third
- crushing tooth rows 4 with different tooth height are arranged on the casing 3 of the roller 1.2.
- the distance of the lateral surfaces 3 of the rollers 1.2 is slightly larger than the height of the lowest height teeth 4.
- Each crushing tooth 4 with greater height than the lowest height is on the lateral surface 3 of the other roller 1.2 opposite a circumferential groove 5 arranged.
- the distance between the groove bottom of this groove 5 and the free end of each tooth 4 with greater than the lowest tooth height is equal to or equal to the distance between the lateral surface 3 of a roller 1.2 and the lowest height tooth 4 of the other roller. 1 ; 2.
- teeth 4 are the distances to the parts of the
- Two-roll crusher can be a particularly tall one
- Shredding ratio of supplied Good namely far higher than 1: 4 can be achieved.
- the rotation of the counter-rotating rollers 1,2 takes place without the control of a transmission as
- each roller 1,2 Brech leopard Holn 4 arranged with different tooth height.
- each row of teeth 4 of a roller 1,2 engages in one
- Embodiment is between two greater than the lowest height having teeth 4 a row of teeth 4 each have a raised tooth back. 6
- connecting back 6 is in the embodiment of the invention shown in Figures 4 bi 7
- the raised tooth back 6 thus engages in the region of the groove 5 and closes it or crushes there befindliches grain with a larger than the target grain size to the target grain size
- Rolls 1,2 is arranged immediately in front of the tooth 4, allows an improved intake behavior of supplied Good with a particularly large diameter, so that this can be crushed in only one crushing process to the target grain size.
- the legs of the circumferential groove 5 are formed diverging toward the free outside.
- respective tooth side wall is the same size or the same size as the distance between the free end of each
- Tooth 4 and groove bottom This also achieves a particularly uniform target particle size while at the same time achieving high work output.
- this form has proven to be particularly wear-resistant and thus durable.
- the lateral surfaces 3 of both rollers 1, 2 can also have a wave-shaped surface. This show the wave tips
- Wave tips are crushing teeth 4 arranged.
- Wave troughs are each formed by the grooves 5.
- a respective break-tooth-like shaft tip or a breaking tooth 4 of a shaft tip of a roller 1, 2 enters a trough of the other roller 1, 2.
- the distance gap between the shaft tip or crusher tooth 4 and wave trough formed at a shaft tip is in each case the same size or similar, so that a particularly uniform target particle size is achieved during comminution.
- the lateral surface 3 of each roller 1, 2 can be provided with crushing teeth 4 and grooves 5 or
- each roller 1,2 respectively be formed several segments 8.
- the segments 8 are individually solvable and neither fastened on or on the roller 1,2, while forming the lateral surface 3, arranged. This makes it possible for rolls 1,2 the only slight damage or small
