Problems solved by technology

However, it should be noted that, despite the anti-adhesion coating, high tangential velocity transport especially in the vertical direction can lead to severe clumping of material in the interception enclosure
[0008] The rotating flail must therefore move through the relatively loose material being conveyed, and also through the compact agglomerated material in the housing, which causes high wear on the rotating shaft and unnecessarily high drive energy levels

Embodiment Construction

[0046] The comminution device according to the invention is shown in side view in FIG. 1 and in front view in FIG. 2 . The comminution device basically comprises a rotor 7 and is fastened to the material conveyor 3 by means of a support frame 2 . The conveyed material, such as foundry sand, is arranged on a belt 4 running flat and supported by support rollers 5 on the frame of a belt conveyor 6 . The rotor 7 or its shaft 13 is fixed laterally in a bearing 8 which is in turn fixed to the support frame 2 . The rotor 7 is driven by a V-belt drive 10 by means of an electric motor 9 . The motor 9 is fastened to a motor rocker 11 so that the V-belt drive 10 can be tensioned by means of a pressure screw 12 . Fixed to the central shaft 13 of the rotor 7 is a rotor part 14 having blade-shaped comminution tools, simply referred to as “blades 24 ”, which blades 24 have beveled ends 27 . The gap between the outer end of the comminution tool and the belt 4 can be set by means of a suita...

Abstract

The invention relates to a device for size-reducing agglomerates and the like material to be reduced in size. The device comprises a rotatingly driven rotor (1) having a plurality of wing-type size-reduction tools (24) that can be brought into contact with the material in order to cut it. The aim of the invention is to provide a device for size-reducing agglomerates and the like material and a corresponding method which allow better size-reduction results and prevent, in combination with additional methods, the material from baking on. For this purpose, the size-reduction tools are composed of narrow knives (24) the thickness thereof measured in the axial direction of the rotor does not exceed 20 mm and the spacing between the knives in the axial direction is not more than 50 mm.

Description

technical field [0001] The present invention relates to a device and method for comminuting agglomerates or similar materials which can be comminuted by mechanical blow, wherein the device comprises a rotor which can be driven in rotation and has a plurality of blade-like comminuting tools which pulverize The tool can be in contact with the material to be shredded. Background technique [0002] A corresponding device is known, for example, from the specification "Lockrungsschleuder" ("Loosening centrifulseparator") by VHV Anlagenbau, which is used to crush molding sand agglomerates. [0003] When handling substance systems with very fine particle sizes or containing binders, for example during discharge or after mixing or granulation processes, a not insignificant fraction of the flowing material can accumulate in an undesired manner to form large Agglomerates or clumps. These agglomerates generally have lower compressive strength and are easier to break down into small pa...
