Definitions
- the invention relates to a method for continuously autogenous grinding of a flowable, insoluble particle containing different diameters Treated goods according to the preamble of claim 1, and a device for performing the method according to the preamble of claim 8.
- the grinding of particularly hard materials such as silicates and carbides is complex. It has become known through use in practice use agitator mills, each with a cylindrical container have in the concentric a high-speed driven agitator is arranged.
- the grinding container is at least essentially with Auxiliary grinding bodies filled.
- the material to be treated is in a flowable form, for example, slurried with water, the container on one End fed and leaves the container at the other end. The mixture the material to be treated and auxiliary grinding media are turned into an intensive movement is shifted so that an intensive grinding takes place.
- a grinder auxiliary device In the area of the regrind outlet, a grinder auxiliary device must be used be provided, by means of which the auxiliary grinding bodies can be separated from the material to be treated, so that the latter is free of auxiliary grinding media can leak. Wear is when grinding extremely hard particles the grinding aid body large. If on the other hand low-quality regrind are ground as mass products, then - even if the auxiliary grinding body wear is not too big - the cost of grinding auxiliary body wear not portable compared to the value of the regrind. About that In addition, there is a very great risk that the grinding aid retainer through regrind particles that are still too large and / or worn Grinding auxiliary body is added, which at least leads to malfunctions or can also lead to partial destruction of the agitator mill. This There is a particular danger if the throughput is high Treated goods, i.e. correspondingly high flow rates of the material to be treated is worked in the agitator mill.

So there are no independent alien grinding aids used; furthermore there is no auxiliary grinding device retention device necessary because they are used as auxiliary grinding bodies Particles remain in the grinding chamber. Malfunctions due to clogging a grinding aid restraint device can no longer occur.
- the material to be treated is classified into larger particles Diameter, which are used for grinding and in smaller particles Diameter to be ground. The particles bigger Diameters are entered into the grinding chamber of the agitator mill and stay there. Then only the pre-classified material to be treated is used for grinding with particles of smaller diameter through the grinding chamber guided.
