Embodiment Construction

[0018] figure 1 A horizontal agitator ball mill is shown. An agitator ball mill generally includes a stand 1 supported on the ground 2 . A drive motor 3 with a controllable rotational speed is arranged in the frame 1 and is equipped with a V-belt pulley 4 by means of which the drive shaft 7 of the mixer ball mill passes through a V-belt and a further V-belt pulley 6 can be driven. In the upper part of the bracket 1 , the drive shaft 7 is supported by a plurality of bearings 9 .

[0019] A substantially cylindrical grinding container 10 is releasably mounted to the upper part 8 of the stand 1 . The cylindrical grinding container 10 comprises an inner wall 11 and is closed by a first cover 12 at the end facing the upper part 8 and by a second cover 13 at the opposite end. The grinding container encloses the grinding chamber 14 . Thus, the inner wall 11 forms the outer boundary of the grinding chamber.

[0020] A stirring shaft 16 is arranged concentrically with a common ce...

Abstract

The application relates to an agitator ball mill, which comprises agitating discs (18) located on an agitating shaft drivable in a spinning direction (38) and provided with entraining profiles (35). These entraining profiles (35) are formed by channels (36), with its-in relation to the spinning direction (38)-trailing wall (39) an inner channel section (40) running radially straight relative to the central longitudinal axis (15) and having a length f, and in the further course an outer bent-off channel section (41), which is bent off counter to the spinning direction (38). The outer channel sections (41) are closed radially to the outside by a peripheral portion (42) of the agitating disc (18) having a radial width e.

Description

technical field [0001] The present invention relates to agitator ball mills and to agitating discs for agitator ball mills. Background technique [0002] In the stirrer ball mill known from DE 1 632 424 with a grinding chamber arranged horizontally, stirring discs with circular entrainment profiles are known, which can be formed by openings or grooves or by flat grooves. The entrainment profile is circular and has a radius of curvature of 50% to 100% of the radius of the disc. The inclination angle increases from 30% to 50% starting from the edge of the disc in the direction towards the center of the disc. Therefore, a substantial increase in the efficiency of dispersion is to be achieved without damaging the grinding body. Due to the large radius of curvature, the correspondingly shaped entrainment contour terminates on the inside at a large radial distance from the stirring shaft, and indeed on the lateral side of the stirring shaft. At the radially inner end, the entra...
