Definitions
- Such devices are u. a. in various forms as so-called Agitator mills known.
- Such agitator mills have a grinding container, which delimits a grinding chamber in which a rotor is arranged. There are auxiliary grinding bodies in the grinding chamber. The regrind flows through the grinding chamber and is essentially caused by the movement the grinding aid is crushed, grated and dispersed.
- roller mills known in which two or more rolls forming one each Grinding gap are provided, the grinding gap between two rollers is adjustable. The ground material is subjected to high shear stresses in the grinding gap exposed and thereby crushed, grated and dispersed.
- roller mills are used, among other things, in the manufacture of printing inks used. Their disadvantage is that the regrind after each pass caught by the roller mill and fed to it again got to.
- the invention has for its object a device of the generic type To create a way in which the Regrind can be repeatedly sheared.
- the essence of the invention is that by the design the device grinds the grinding gap in one pass is fed several times because it is due to the rotational forces on the first grinding surface on approximate helical regrind tracks moved to the grist outlet.
- the basic effect ago the device according to the invention is best with a roller mill comparable, which has a hollow roller within which an inner roller is arranged to form a grinding gap or grinding gap.
- the grinding container could also be referred to as a hollow roller.
- the device according to the invention works - unlike agitator mills - without auxiliary grinding bodies.
- a device has one Stand 1 in which an electric drive motor 2 is mounted. He points a lower first output 3 and an upper second output 4, the via a transmission 5 with continuously variable transmission from the engine 2 is driven.
- On the stand 1 is a grinding container 6 by means of a lower journal 7 in bearings 8 rotatably mounted. It becomes from the first Output 3 driven by means of a belt drive 9.
- a grinding roller 10 is arranged on a roller drive shaft 11 is attached.
- the drive shaft 11 is very stocky executed and placed in two with the greatest possible distance from each other Bearings 12, 13 stored in a bearing slide 14.
- the storage sled 14 is transverse in a guide 15 in the upper region of the stand 1 to the - essentially vertical - central longitudinal axis 16 of the drive shaft 11 with grinding roller 10 slidably mounted in the direction 17.
- the drive shaft 11 and thus the grinding roller 10 are from the second output 4 of the motor 2 can be driven via a drive shaft 18 and a belt drive 19, wherein the propeller shaft 18 via a sliding bearing 20 with the second output 4 is coupled so that displacements of the bearing slide 14 in direction 17 are compensable.
- the bearing slide 14 is hydraulic Actuable feed drives 21, for example in the form of hydraulic acted upon piston-cylinder drives, in a desired Movable position and lockable or lockable in this position.
- feed drives 21 are articulated on the stand 1. They are still can also be controlled individually for reasons to be explained later.
- the grinding container 6 is approximately frustoconical in shape in any case rotationally symmetrical to an axis of rotation 22 through the journal 7 goes. It has a bottom 23 and a frustoconical shape upwardly widening container wall 24.
- the grinding container 6 has one upper opening 25, in the vicinity of which on the outside of the container wall 24 an annular, and preferably cylindrical, Support surface 26 is formed, which in turn is supported in the stand 1 Support rollers 27 abut.
- the inner surface of the container wall 24 forms a trimmed truncated cone first grinding surface 33.
- the surface of the grinding roller 10 forms a likewise finely ground cylindrical second grinding surface 34.
- the axis of rotation 22 of the grinding container 6 closes with the axis 16 of the Grinding roller 10 an angle a, which is completely or at least substantially half the opening angle of the frustoconical first Corresponds to grinding surface 33.
- both grinding surfaces 33 and 34 also be slightly spherical.
- a sensor 35 is also provided on the stand 1, by means of which the Grist level 36 in the grinding container 6 can be detected.
- the signals of this sensor 35 go to a central control 37, via which the drive motor 2, the gear 5 and thus the speeds of grinding container 6 and grinding roller 10 can be influenced.
- this is central Control 37 controls a regrind pump 38.
- the controller 37 can be freely programmable.
- the mode of action is as follows:
- the first grinding surface 33 and the second grinding surface 34 delimit one Grinding gap 39, which runs essentially parallel to the axis 16, such as the 1 and 2 can be removed.
- the diameter c of the grinding roller 10 is in any case smaller than the projection of the diameter d of the inner one Floor area 40 to the diameter c. The following therefore applies: c ⁇ d x cos a.
- the bearing slide 14 with the drive shaft 11 and the grinding roller 10 is have been moved by means of the feed drives 21 into a position in which the Grinding gap 39 a desired width and possibly a desired course Has.
- the grinding container 6 is in the direction of rotation 41 and the grinding roller 10 in Direction of rotation 42 driven, ie - as can be seen in FIG. 3 - in the same direction, so that the regrind in a rectified direction 43 the grinding gap 39 is promoted. 1 and 2 can be seen the grist level 36 is very low, so that the grinding roller 10 is only slightly Immerse the circumference in the regrind. When the grinding container stops 6 and grinding roller 10 is the largest part of the grinding gap 39 above of the regrind fill level 36.
- the regrind moves approximately in one helical movement relative to the first grinding surface 33 above for opening 25.
- the relative speeds are generally can be influenced very strongly that the grinding container 6 on the one hand and the grinding roller 10 on the other hand with different, changeable Speeds are drivable.
