HOECHST AKTIENGESELLSCHAFT HOE 89/F 326 D.Ph.HS/sch Description Vibratinq stirred ball mill The invention relates to a stirred ball mill, whose grinding system additionally exe!cutes a vibrating motion.
Vibrating mill~ and stirred ball mills are known as comminution systems. Disadvantages of both systems are the relatively large dead zones which impair the fineness of grinding and the space-time yield~. The invention is intended to remedy this.
The invention achieves the object by means o~ a stirred ball mill which is mounted on a bearing provided with an eccentric drive, the fitirrer being connected to the stirrer drive via an articulated shaft.
As a result of combining the two grinding systems in one installation, the previously dead grinding æones are largely activated 80 that higher fihenesses of grinding are possible at greater space-tLme yields as compared with the respective individual system~.
The invention is explained in more detail below by reference to a drawing which merely illustrates one possible embodiment. The Figure shows the mill according to the in~ention in side view, represented diagrammatic-ally without grinding bodies.
A stirrer shaft 2 mounted on both ~ides and having stirrer elements 3 i~ located in the grinding tube l. The : ~: grinding bodies in~loos form (not shown) are poured in via the charging branch 4~ The grinding tube l is mounted on a bearing 16 provided with an~eccentric drive 5. ~he 3Q tirrer drive ~not shown) is connected to the stirrer via an articulat;ed sha~t 6, which absorbs the vibrating ; motion of the~grinding tube l and of the stirrer shaft 2.
' " . ', : ' , ,: -"
Both drives can be fitted with an infinitely controllable gearbox. Suitable stirrer elements 3 are rods, di~ks or the like. The grinding tube 1 can be provided with double jackets 7, 7a, to which coolants or heating media can be 5fed via orifices 8, 9, 10, 11, or discharged from them.
The stirred ball mill can be operated continuously ordiscon~inuously. The product to be ground is charged dry or in a suspension via the charging orifice 12 and leaves the mill via the discharge orifice 13. 14 and 15 indicata measurement branches. As a r~ssult of the eccentric drive 5, the stirred ball mill i~ simultaneously operated as a vibrating mill. The amplitude of the vibration can be 4 to 12 mm at frequencies of 200 to 1500 ~ibrations per minute.
The advantages of the grinding device according to the invention over the known vibrating mill or the known stirred ball mill are demonstrated by reference to the tests below: three different feed products having varying, D50 grain sizes were ground in the grinding devics accord-ing to the invention, namely by dif~erent operating pro-cedures. The grain analyses were determined on a grain size measurem~nt instrument made by Cilas, op~rating by the laser principle. The ground material was dispersed in water hefore measurement, and the dispersion was treated ultrasonically for one minute. The samples were measurad in triplicate.
The test results can be ~een in the Table which follows.
The figure indicate the average grain size D50 i~ ~m, nam21y Column 1: unground;
Column 2: ground with pure vibrating mill operation;
Column 3: ground with pure stirred ball mill operation;
Column 4: ground with superposed stirxed ball mill operation and vibrating mill operation according to the inv~ntibn.
