Definitions
- the invention relates to a roller press for crushing, compacting or briquetting of material, comprising a press frame, two in the press frame to form a nip juxtaposed rollers and a roller nip arranged above the feed slot through which the material is fed to the nip, wherein the feed chute a or a plurality of vertical or inclined against the vertical oriented shaft walls to form a height over the height at least partially constant or expanding from top to bottom cross-section. wherein the feed chute is provided with a measuring device for determining the filling level of the material in the feed chute,
- Such a roller press is particularly preferably a good bed roller mill, which preferably serves for the comminution of material.
- the invention also includes roller presses or good bed roller mills for compacting or briquetting material.
- the two press rollers are rotatably driven, wherein the two press rollers are driven in opposite directions.
- one of the two rollers is formed as a fixed roller and the other roller as a Loswalze (laterally displaceable) mounted, said movable Loswalze is acted upon by a hydraulic system supported on the press frame.
- two loose rollers or other frame concepts can be realized. The principle according to the invention is independent of this. The material will
- Roller presses preferably, high-bed roller mills
- roller presses are typically operated with a stock for efficient operation. This means that for a continuous and thus trouble-free and economical operation at the desired operating point of the roller press in the feed chute always a sufficient level of the material must be present, so that there is always sufficient material for the entry into the nip available. Because the effective between the rollers nip generally depends on the level of the material in the feed chute, so that the level can have an influence on the throughput of the roller press, which influence decreases with increasing filling level. In practice, therefore, one often strives to ensure a constant level in the feed chute.
- the determination of the filling level with the aid of a measuring device is of practical importance, wherein preferably the conveying means (eg conveyor belts) for filling the feed chute via a suitable control or regulation (eg a speed control of the conveyor belts) can be coupled to a level signal in the feed chute.
- the conveying means eg conveyor belts
- a suitable control or regulation eg a speed control of the conveyor belts
- the invention relates in particular to the processing of material with low flowability, for.
- material with low flowability for.
- As ore-containing material in particular finely ground ores, so-called fine ores.
- a (wet) iron ore concentrate is processed for subsequent pelleting.
- the invention is therefore based on the object to provide a roller press of the type described above, which (even) in the processing of materials with low flowability (especially in wet and sticky feed materials) allows a simple level measurement waiving radiometric methods or other radiation-based methods ,
- the invention teaches in a generic roller press of the type described above, that the measuring device as a gravimetric measuring device for a gravimetric level measurement
- gravimetric fullness measurement means a level measurement on a mechanical basis without radiometric or radiation-based measurements, in which the fill level is determined by measuring the mass or the resulting weight of the material.
- the invention is initially based on the recognition that it is absolutely necessary for certain applications, in particular for the processing of material with low flowability, to work with a feed chute, which does not taper downwards, but either one over the height having constant cross section or preferably a downwardly widening cross section.
- the invention also encompasses embodiments in which the feed chute only has a constant cross-section in certain sections, so that, in particular, feed chutes are also detected which expand in a staircase-like or stepped manner downwards.
- the invention has now recognized that even with such a geometry of the feed chute, in which an adhesion of the feed material to the shaft walls avoided and thus a constant flow of material to be achieved, can be used with a gravimetric level measurement.
- the flow behavior of bulk solids in a shaft leads to stresses in the bulk material and, taking into account the wall friction and the bulk material properties, to wall stresses. Due to the bulk material, horizontal stresses act in a shaft cross-section and, due to the support on the shaft inner walls, these result in weight forces at the bearing points of the feed shaft.
- the material thus generates a surprisingly high force transmission to the shaft wall in the form of a relevant mass or a relevant vertical force component that is measurable. This corresponds to the material properties and depending on
- Geometry of about 35% to 45% of the feed mass is particularly suitable for the processing of material with low flowability, especially since such material allows a particularly effective power transmission to the shaft walls.
- An interesting aspect is the fact that in this way a level measurement is possible both statically (eg after filling the feed chute) and dynamically (eg for continuously slipping material during the press operation).
- a downwardly expanding feed chute is used. This has one or more shaft walls, which (at least in sections) at a (negative) angle of z. B. 0.1 ° to 10 °, preferably z. B. 0.5 ° to 5 ° are oriented against the vertical.
- the measuring device has one or preferably a plurality of load cells, which support the feed chute. Consequently, the weight force generated by the total mass of the feed chute is measured via the load cells, wherein in the manner according to the invention this is dependent on the fill level of the material in the feed chute.
- the feed chute is on one or more load cells by z.
- the feed shaft is arranged with the interposition of the load cells on the press frame.
- the feed chute may have a lower frame or be connected to a lower frame, this lower frame is arranged with the interposition of the load cells on the press frame. Since the loading shaft under
- Interposition of the load cells in the vertical direction must be movably arranged on the press frame, it is expedient to connect the feed shaft with the interposition of a resilient in the vertical direction (frame-like) compensator to the press frame.
- a compensator can, for. B. have an upper flange for connection to the feed chute or the lower frame and a lower flange for connection to the press frame, wherein between the upper flange and the lower flange, an elastic and / or sliding frame is provided, the z. B. of elastomeric material, for. B. made of rubber, or from vertically against each other and / or slidably arranged shaft elements can be made.
- the load cells can then z. B.
- the load cells can be used on commercial weighing cells z. B. can be designed as electromechanical load cells. By elastic deformation of a deformation body, the electrical resistance of one or more strain gauges integrated therein (DMS) changes. About z. B. a bridge circuit, the resistance change in a voltage signal proportional to the weight can be displayed. In principle, however, differently designed load cells can also be used.
- DMS strain gauges integrated therein
- the already described standing weighing of the feed shaft takes place.
- the feed shaft is usually made of metal, z. B. made of steel and experiments have shown that for different materials, eg. B. for ore-containing material, eg. As fine ore, a sufficient power transmission to the
- Container wall for a reliable gravimet level measurement takes place.
- a coating eg. B. with a plastic coating.
- the shaft walls inside z. B. with plastic plates, z. B. be lined from polyethylene or the like. Even with such coatings, the invention can be realized.
- the invention relates not only to the described roller press, but also a method for determining the level of material in a shaft, in particular in the course of feeding a roller press of the type described above.
- the inventive method is therefore independent of the specific field of application Roller presses placed under protection.
- This method is characterized in that the shaft, z.
- As feed chute one or more vertical or inclined to the vertical oriented shaft walls to form a constant over the height or from top to bottom expanding cross-section.
- the method is characterized in that the filling level is determined gravimetrically by means of load cells applied by the shaft, by measuring with the weighing cells a weight force or mass introduced into the container walls and from this the filling level is determined.
- this method is used in the course of feeding a roll press of the type described, so that the shaft is formed as a feed shaft of a roll press.
- the method of the invention relates to the processing of materials with low flowability.
- Low flowability in the context of the invention means materials with a flowability ff c of less than 10, preferably less than 4.
- the flowability ff c is the ratio of the solidification stress and the compressive strength.
- Hardening stress is the stress that is required to compact a bulk material sample in a hollow cylinder. If the load is removed in the vertical direction and the hollow cylinder is removed and the cylindrical bulk material sample is subjected to compressive stress, the sample will break or flow when the compressive strength is reached. Low fluidity materials have high internal friction, so they also transfer friction to vertical or negative shaft walls. This effect is utilized in a preferred embodiment within the scope of the invention. Of particular importance is also the fact that the inventive method not only allows a static level measurement, but also a dynamic level measurement and consequently allows a level measurement in the continuous operation of the roller press.
- the transfer of the weight of the material in the hopper to the shaft wall depends on various factors, with the weight force, which also results from the wall tension, not being linearly dependent on the fill level.
- the filling level is determined using one or more conversion functions which are made available for the respective shaft geometry and / or the respective material.
- the material properties including the flowability ff c and the moisture content of the material, the wall inclination / shaft angle and the friction coefficient between the material and the shaft wall have an influence.
- a corresponding and possibly also non-linear conversion of the measuring signal of the weighing cells into a corresponding filling level takes place, including the material and construction parameters mentioned above.
- the invention is primarily concerned with level measurement, taking into account the aspects described.
- the subject of the invention is also a method for operating a roller press using the level measurement described. It is possible to use the determined level or the signals measured with the load cells for controlling or regulating the filling and / or roller press.
- filling of the feed chute with one or more filling units eg conveyor belts
- such filling units can be controlled or regulated taking into account the determined signals or filling levels.
- Fig. 1 schematically simplifies a roll press in one
- Fig. 2 is a roller press in a perspective view.
- a roller press is shown in the embodiment as a good bed roller mill.
- This is used in the embodiment of the comminution of material, eg. B. of ore-containing material.
- material eg. B. of ore-containing material.

- the feed chute has in the exemplary embodiment at least two opposite shaft walls 4a, which are each inclined vertically at an angle ⁇ to the vertical, so that the feed chute 4 has a widening from top to bottom cross-section.
- the (negative) angle ⁇ can be about 0.1 ° to 10 °, preferably only 0.5 ° to 5 °, z. B. 0.5 to 2 °.
- the roll press is equipped with a measuring device 5, with which the level of the material in the feed chute 4 can be determined and monitored. According to the invention, this measuring device 5 is designed as a gravimetric measuring device, so that a gravimetric level measurement takes place.
- this gravimetric measuring device 5 has a plurality of weighing cells 6, which are acted upon by the feed chute 5.
- this is realized in such a way that the feed chute 4 stands on the weighing cell 6.
- the feed chute in the embodiment a lower frame 7, said lower frame 7 is arranged with the interposition of the load cells 6 on the press frame 1.
- the feed chute 4 can be connected to the press frame 1 with the interposition of a compensator which is elastic or displaceable in the vertical direction. Details of the compensator are not shown.
- the fill level of the material in the feed chute 4 can not only be static (eg after filling or emptying), but also dynamically and thus continuously during filling and (simultaneous) emptying in the feed chute 4 Determine and monitor the operation of the roller press. So far, such a gravimetric level measurement only came down funnel-shaped
- tapered feed halls used, in which, in particular, due to the geometry of an introduction of the weight of the material takes place in the shaft walls.
