    Kugelmühle.   



   Der Kraftbedarf zum Betriebe einer Kugelmühle ist im wesentlichen abhängig von dom Gewicht des Mahlgutes mit den Kugeln und von der Entfernung des Schwerpunktes dieser Füllung von der Drehachse der Kugelmühle. Je grösser die Mühle ist, um so grösser ist auch ihre Leistungsfähigkeit und damit auch ihr Kraftbcdarf zur Überwindung des durch das   hocbgeführte   Gut erzeugten Drehungsmomentes, welches noch durch die zur weiteren Vermahlung in die Trommel zurückwandernde Siebgröbe vermehrt wird. 



   Der Zweck der vorliegenden Erfindung besteht nun darin, den   Kraftbcdarf bei   langen 
 EMI1.1 
 DurchmessererhältalsdasAussensieb. 



   Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung in Fig. 1 im Längsschnitt und in Fig. 2 im   Querschnitt nach -. r   der Fig. 1 zur Darstellung   gehracht.   



   Die   Einführung   des Mahlgutes in die Mühlentrommel geschieht wie üblich durch den Trichter B.   Xach   erfolgter teilweiser Zerkleinerung fällt das Mahlgut durch die 
 EMI1.2 
 in der geraden Verlängerung des   Siebmantpls   (punktierte Linien FI) oder wird durch einen zylindrischen Blechmantel gebildet (strichpunktierte Linien F2), welcher etwas ausserhalb des Siebes E anschliessend, den vorderen Teil der Trommel   umhüllt,   um die gesamte Sieb- 
 EMI1.3 
 hiebei ergebende Kraftmoment ist nun bei der neuen Mühle dadurch bedeutend verringert, dass der Blechmantel F ganz nahe an die Mahltrommel   A   herangerückt ist, so dass zwischen beiden nur ein geringer Abstand bleibt, der nicht grösser zu sein braucht,

   als die Höhe der auf den früheren Blechmänteln befindlichen achsialen oder   schrägen Förderleisten.   



   Die Zuleitung der von den Sieben abgleitenden   Grobe auf   den Blechmantel F erfolgt 
 EMI1.4 
 die wie üblich ausgebildete Einführungsvorrichtung G gelangt die Siebgröbe wieder in die   Mahltrommol     A   zurück.

    Ball mill.



   The power required to operate a ball mill is essentially dependent on the weight of the ground material with the balls and on the distance of the center of gravity of this filling from the axis of rotation of the ball mill. The larger the mill, the greater its efficiency and thus also its power requirement to overcome the torque generated by the hoisted material, which is increased by the screen size moving back into the drum for further grinding.



   The purpose of the present invention is now to reduce the force required for long
 EMI1.1
 Diameter is given as the outer sieve.



   In the drawing, an embodiment of the invention is shown in Fig. 1 in longitudinal section and in Fig. 2 in cross section according to -. r of Fig. 1 for illustration.



   The ground material is introduced into the mill drum as usual through the funnel B. After the partial comminution has taken place, the ground material falls through the
 EMI1.2
 in the straight extension of the screen jacket (dotted lines FI) or is formed by a cylindrical sheet metal jacket (dash-dotted lines F2), which then surrounds the front part of the drum slightly outside the screen E, around the entire screen
 EMI1.3
 The resulting moment of force is now significantly reduced in the new mill because the sheet metal jacket F is moved very close to the grinding drum A, so that there is only a small distance between the two, which does not need to be greater,

   than the height of the axial or inclined conveyor strips on the earlier sheet metal casings.



   The feed of the coarse material sliding off the sieves onto the sheet metal jacket F takes place
 EMI1.4
 the introduction device G, which is designed as usual, returns the screen size to the grinding drum A.
