Definitions

  • the invention relates to a method and a device for wet grinding of solid particles in liquids by means of an agitator mill consisting of at least one grinding chamber containing grinding media, at least one rotor, wherein the grinding chamber and the rotor can be set in rotation independently of one another by means of at least one drive and the grinding stock can be introduced into the grinding chamber from the outside via a hollow shaft or via a grinding chamber.
  • Such a method and such a device is known from DE-AS 12 23 236. It is an agitator ball mill in which the grinding material can be separated from the coarse material solely by the action of the centrifugal forces.
  • the regrind enters the settling chamber with separation of the coarse material and then exits through a fan alley.
  • cylindrical, axially extending or conical separating screens can also be used in an agitator trough above the stirring disks. With this arrangement, the regrind is separated from the agitator trough at several levels.
  • the regrind which is arranged through sieves, which are arranged above the highest stirring disks, looking upwards in the direction of arrow a, is finer milled than the regrind, which emerges from the grinding chamber through the sieves which are provided in the lowest level .
  • the agitator mill has a grinding vessel and an agitator rotor with a vertical rotor axis, between which there is a rotationally symmetrical grinding chamber containing grinding vessels.
  • the ground material is introduced into the grinding chamber through the inlet openings and moved radially outwards in a pump section which is arranged above the agitator rotor.
  • the ground material then runs around the outer circumference of the disk-shaped agitator rotor and is then generally radially inward again to form a circulation cut led.
  • a disadvantage of this embodiment is the long path of the millbase, from the inlet opening through the pump sections above the rotor, the calming sections below the rotor to either a sieve, which is arranged below the calming sections, or to the circulation section mentioned above.
  • the sieve arranged below the process zone can be blocked by the heavy coarse particles which have been separated from the bulk material flow.
  • the object of the present invention is to reduce the disadvantages of the prior art, i.e. Simplification of the process control, avoidance of the expensive cooling devices in the actual grinding device and the applicability to the widest possible spectrum of the material to be processed.
  • the object of the invention is in particular to optimize the pressing of the grinding media and thus to reduce the wear on all rotating parts. By optimizing the pressing, a high degree of grinding is also achieved.
  • the object is achieved in that the grinding media located in the grinding chamber are strongly compressed in the direction of increasing radius, the grinding material being opposed once from the outside to the remaining grinding media. flows through the body layer and loosens, and is then thrown out through outlet openings.
  • the inventors have shown that an optimally ground, homogeneous ground material will emerge from the grinding chamber if the centrifugal force of the grinding chamber, if applicable, the compression of the grinding media and the flow of the ground material are coordinated with one another in such a way that they are in equilibrium. It has also proven to be advantageous to arrange separating devices in the grinding chamber below the outlet openings. The openings of the sieves are adjusted so that only the ground material with the predetermined diameter distributions is conveyed and that the spherical grinding bodies remain in the conical area of the grinding chamber.
  • the centrifugal force of the grinding chamber is a function of the speed of the drum and is regulated depending on the torque of the shaft.
  • the flow force of the millbase is a function of the volume flow and viscosity of the millbase and is also regulated as a function of the torque of the shaft.
  • the separating device is advantageously located in the centrifugal field, so that coarse particles that are not thrown outwards automatically remain in the centrifugal field and are included in the comminution process. This effect cannot be achieved with the screen arrangement in DE 39 43 765 C2, which is provided below the process zone.
  • the separating device is expediently arranged in a rotating manner on the grinding chamber, possibly on the rotor.
  • the agitator mill is advantageously arranged directly in a collecting container for the ground material or connected to a line arrangement.
  • a centrifugal field is expediently formed in the grinding chamber, the dimensions of which are such that the ratio of its radial length to the axial height is in the range greater than 4: 1.
  • the grinding chamber is advantageously arranged standing vertically or lying horizontally. Further advantageous configurations result from the subclaims and their combinations
  • FIG. 1 shows a sectional drawing of the Ruhrwerk mill.
  • FIG. 2 shows an example of a separating device.
  • FIG. 3 schematically shows a centrifugal field in a grinding chamber.
  • FIG. 4 shows a line arrangement of the device according to the invention.
  • FIG. 5 shows another example of a separating device
  • the agitator mill consists of a grinding chamber 1 with a rotor 2.
  • the grinding chamber 1 is driven via a drive 8 'and a hollow shaft 5'.
  • the grinding chamber 1 is filled with grinding bodies 3.
  • the ground material 4 passes through the hollow shaft 5, through the lateral openings 39 of the hollow shaft 5, through the cavities 26 in the rotor 2 into the grinding chamber 1.
  • the ground material 4 then reaches the circumference of the rotor 2 through the grinding bodies 3 into the interior of the grinding chamber 1.
  • At the upper end of the grinding chamber 1 there are openings 11 which serve as outlet openings for the material to be treated.
  • shielding covers 30 are attached via the openings 11, which extend to the circumference of the grinding chamber 1, so that the ground material can spray outwards as a result of the centrifugal forces.
  • Separating devices (sieves) 110 are arranged on the inner wall of the grinding chamber 1 below the outlet openings 11. These separation devices 110 lie in a centrifugal field 70, which is formed in the grinding chamber 1 between the inner wall of the grinding chamber and the outer wall of the rotor 2.
  • the openings of the sieves are matched so that only the regrind 4 with the predetermined ones Diameter distributions is required, with the spherical grinding media 3 and the coarse particles remaining in the grinding media layer in the grinding chamber. The coarse particles are thus automatically included in the comminution process
  • the entire Ruhrwerk mill is arranged directly in a collecting container 14. This can be provided with cooling (not shown).

  • the width of the friction gap is adjusted so that only the ground material 4 with the predetermined diameter distributions is required, the spherical grinding bodies 3 and the coarse particles remaining in the grinding body layer in the grinding chamber As a result of the centrifugal force, the ground material to be treated is sprayed outwards through the opening 114 at the lower end of the grinding chamber 1.

Abstract

L'invention concerne un procédé et un dispositif pour le broyage à l'état mouillé de solides et la dispersion de particules de solides dans des liquides. Selon l'invention, ces opérations sont effectuées dans un moulin agitateur constitué d'au moins une chambre de broyage (1) contenant des corps de broyage (3) et d'au moins un rotor (2). Le produit à broyer (4) est introduit dans la chambre de broyage depuis l'extérieur, par l'intermédiaire d'un arbre creux (5) ou bien directement, et dirigé, en une seule fois, de l'intérieur vers l'extérieur, à travers les corps de broyage (3) en vrac, puis conduit de façon à traverser, en sens inverse, de l'extérieur vers l'intérieur, la couche de corps de broyage résiduelle, après quoi il passe par des ouvertures de sortie (11). Le dispositif se caractérise en ce que la force centrifuge s'exerçant dans la chambre de broyage, éventuellement la compression des corps de broyage et l'écoulement du produit à broyer sont en équilibre. Dans la chambre de broyage (1), dans la zone des ouvertures de sortie (11), se trouve au moins un dispositif de séparation (110).
