Definitions
- the invention relates to a feeding device for a high-pressure roller press for Hockdruckzerkleintation of ground material, which controls the material to be ground in a nip between two rollers of the high-pressure roller press gives up.
- the nip is wider than the largest extent of the comminuted material to be ground. It is necessary to feed the nip with millbase so that a certain amount of the ground material can continuously pass through the nip. Because if the nip is loaded with too little amount of material to be ground per unit of time, in extreme cases the material to be ground is no longer comminuted or the high-pressure roller press acts like a crusher. If, on the other hand, too large an amount of regrind is added to the Given the crevice, the high-pressure roller press can become overloaded with the result that it begins to vibrate.
- the nip increases and decreases in resonant frequency and the rotational speed varies with resonant frequency, since in an overload, the rollers are repeatedly braked by the existing too large ground material and accelerated by the drive motors again. Therefore, in the high-pressure crushing in the nip is to ensure that the nip is applied to a suitable extent with millbase.
- the amount of feed depends heavily on the nature of the material to be ground.
- the parameters to be considered here are the particle size distribution, the average particle size and the uniformity of the available ground material flow onto the nip.
- the material to be ground should be fed evenly from above into the nip.
- the amount of material dispensed has a significant influence on the desired smooth running of the high-pressure roller press.
- the metering function of the feeder over the nip has been steadily improved.
- document WO 201 0/003850 discloses a feeding device with which the material to be ground is guided in a controlled manner into the nip between two rollers, wherein the feeding device has at least two rotary valves, through which at symmetrical position a certain middle Total amount per unit time can be placed on the high-pressure roller presses.
- the intake behavior is also influenced by the material bed in the room above the rollers.
- Bulk material (bulk) is an accumulation or volume of Mahlgutmenge in the space above the compaction zone to understand.
- the optimum material fill is determined by the parameters grain size of the material to be ground, humidity and the angle of repose.

- the material chute can be adjusted in height via a hydraulic device, wherein the hydraulic device with the support device and the shaft of the material chute is in communication and engages the shaft.
- Another preferred embodiment of the invention provides that the material chute is arranged in the material feed such that the material to be ground can be dispensed centrally above the nip onto the rolls of the high-pressure roller press.
- material chute within the feeder is arranged so that the shaft or material inlet and material outlet are each centrally above the nip and the shaft can be adjusted centrally above this in height. This ensures a uniform task of the ground material.
- the material chute is vertically adjustable such that the material outlet can be moved from an upper position to a lower position and vice versa.
- the material bed is the amount of material that is deposited on the rollers over a certain area, the material feed area.
- Under free bed of material or free Mahlgut thoroughlyung is a loose accumulation or volume of a quantity of material or the ground material to be understood, which forms in the space above the Kompaktzone to the material outlet of the material slide.
- the aggregate may ideally assume a frustoconical shape.
- a further preferred embodiment of the invention provides that when the material outlet is in the upper position, a maximum free bulk of material is formed.
- the material chute can be adjusted in height continuously above the nip via the adjusting device. The highest adjustment is achieved when the material exit a position II above the nip occupies. The lowest adjustment is marked by the position I. Here is the material outlet directly between the rollers.
- the free material bed can be regulated as a function of the height of the material chute which can be adjusted via the adjusting device.
- the free bulk material decreases as the material chute is driven down towards the nip and approaches zero when the material chute is moved to position I.
- a next preferred embodiment of the invention provides that in the position of the material outlet in the lower position no free material bed forms.
- the material chute is moved to its lowest adjustment position, no free bulk material can form in the space above the nip and the material outlet of the material chute.
- the material passes through the material chute directly into the compaction zone and into the nip. On the rollers, the smallest amount of material is given up.
- a further preferred embodiment of the invention provides that the Mahlgutüberlauf issued is formed of a first overflow chute and a second overflow chute, wherein the overflow chutes are fixed or detachably arranged on the material task or on the material chute.
- the task device has for the continuous refilling with regrind and the control of the level of the nach- Grinding material in the chute of the material chute, as well as in the material task itself, a Mahlgutüberlauf issued on.
- Mahlgutüberlauf may provide two overflow chutes, which are preferably fixed or detachably mounted respectively on the opposite shaft walls of the material chute.
- the overflow chutes may be tubular and preferably extend to about the height of the nip.
- the overflow chutes are adjustably arranged on the material chute.
- the possibility of adjusting the material chute and the overflow chutes makes it possible to set a defined free material bed above the rollers and a defined material play gel in the chute of the material chute.
