Definitions
- the invention relates to a Di spergi erhabilit according to the preamble of claim 1.
- agitator mills It is known to separate solids in a liquid phase, e.g. To disperse pigments and fillers in a solution of a binder, in agitator mills by adding mechanical energy.
- the agitator mills contain grinding media, e.g. Sand, and the. Energy is supplied by the movement of rotors arranged in the agitator mill.
- the grinding chamber of the agitator mill is filled with 70 to 90% by volume of sand.
- the regrind flows through the grinding chamber in the axial direction.
- the throughput of the millbase through the milling pot is generally selected such that the prescribed nominal fineness is achieved after one or more passages. This procedure is often referred to as single or multi-pass mode.
- the production output achievable with this procedure can be increased significantly if the procedure described in DE-PS 22 30 766 or DE-OS 19 02 152 is used.
- this circular mode of operation high throughputs of millbase are passed through the mill; after leaving the mill, the millbase flows back into a container from which it is pumped back into the mill becomes.
- the regrind flows in the so-called pendulum drive from a container with high throughputs through the agitator mill * into a second container. This process is repeated until the target fineness is reached.
- the invention therefore relates to a dispersing process according to claim 1.
- Grinding body filling forms a rotating hollow cylinder in the agitator mill due to the centrifugal force.
- the dispersion of temperature-sensitive goods can also be carried out without any problems, since only a slight increase in the temperature of the ground material can be determined per passage through the agitator mill. This heat can easily be extracted from the regrind in an external cooler. With this procedure, a significant reduction in the dispersing energy used is additionally achieved compared to the passage mode.
- fine grinding media can be used at high throughputs through the mill, the use of which is not possible in machines which correspond to the prior art because they are attached to the separating screen at high throughputs. be washed up.
- the invention also relates to an agitator mill for carrying out the dispersion process.
- Fig. 1 shows a vertical longitudinal section through an agitator mill
- Fig. 2 shows a vertical cross section through a
- FIG. 4 a section corresponding to FIG. 1, but with a fixed cylindrical separating screen
- FIG. 5 a section through an agitator mill according to FIG. 1, but with screens arranged on a pitch circle
- Fig. 6 shows a section according to FIG. 2 through the
- FIG. 8 an agitator mill with a fixed dip tube and in 9 shows an agitator mill with a rotating sieve in a space free of grinding media.
- 1 denotes a grinding container in which rotors 2 designed as paddles are arranged.
- the ground material is fed in at 3 and a sieve is shown at 4. 5 with a storage container is designated.
- the rotors 2 are driven by a hollow shaft 6, which at the same time serves to discharge the ground material.
- a turret seal is shown and 8 is the required pump.
- 9 designates a manometer and 10 designates the grinding media bed within the grinding container 1.
- a discharge sieve for residual products is shown and the mill outlet is indicated by arrow 12, while the mill inlet is indicated by arrow 13.
- the cooling water inlet and at 15 the cooling water outlet is 1 t.
- FIG. 2 an idealized millbase path is shown at 16, while the arrows 17 and 18 indicate the radial speed of the millbase or the circumferential speed of the millbase.
- Grist consisting of 30.5% by weight of an alkyl resin 60.5% by weight of titanium dioxide
- Type of grinding media S licium zirconium oxide grinding media (diameter 0.6 - 2.5 mm)
- FIG. 4 shows, as in FIG. 1, a cross section through an agitator mill according to the invention, but now with a fixed cylindrical separating sieve 4.
- FIG. 7 shows, in a representation corresponding to FIG. 5, screens 4 arranged on a pitch circle, but this time fixed, i.e. are not designed to rotate.
- Fig. 8 shows as a grinding body separating device a fixed immersion tube 21 which protrudes into the space free of grinding media. A sieve is not provided.
- FIG. 9 shows, as the grinding body separating device, a screen 22 rotating in the grinding body-free space, the speed of which is independent of the speed of the rotor drive.
