Problems solved by technology

[0009] Immediately adjacent soft substrates are susceptible to wear and abrasion if the wear protection applied to the end of the mixing blade has worn away
After the wear protection part has been removed, the length of the mixing blades decreases very quickly, wherein the corrosion phenomena that occur in this case can also lead to the complete wear protection part and the main body fracture, which can cause the mixer or set in the downstream position damage to the machinery, or at least interruption of its operation
[0010] In addition, the reduced length of the mixing blade leads to a weakening of the mixing results

Embodiment Construction

[0031] figure 1 A mixer 1 is shown which, in the preferred embodiment, is provided with a rotating mixing vessel 2 comprising a circular mixer pan 3 and a cylindrical mixer wall 4 . The mixer also has a rotor 5, arranged eccentrically with respect to the center of the mixing vessel, suspended or cantilevered from above, and extending just above the bottom of the mixer, which carries a plurality of rotors with releasable ends 7 The mixing blades 6 are arranged in multiple planes and extend radially. The mixing container 2 and the rotor 5 are rotated by means of a drive (not shown). The cylindrical arm 4 and mixer bottom 3 are scraped by a stationary combined arm-bottom tool 8 . The mixing container 2 is discharged by means of a central closable bottom discharge opening 9 .

[0032] The rotor 5 includes a polygonal shaft (not shown) on which a plurality of tool holders 10 are detachably arranged one on top of the other. The mixing blades 6 fit in pins (not shown) in the groo...

Abstract

The invention relates to a device for mixing abrasive materials, especially granules, comprising at least one central rotor shaft (5) and mixing blades mounted on and extending substantially radially from the rotor shaft, Therein, the mixing blade comprises a radial inner portion (main body 6) and a radial outer end portion (7). The invention also relates to a corresponding mixing blade. In order to provide a device and a corresponding mixing blade for obtaining long-lasting good mixing results at low cost and maintenance costs, the invention is characterized in that at least the removable end (7) of the mixing blade is directly adjacent to the inside The cross-section of is substantially the same as the cross-section of said radially inner part (6).

Description

technical field [0001] The invention relates to a device for mixing abrasive materials, in particular particles, comprising a central rotor shaft and mixing blades mounted on and extending radially from the rotor shaft. The invention also relates to a mixing blade and a mixing blade tip for such a device. Background technique [0002] The prior art discloses mixers having one or more mixer shafts arranged perpendicularly to the bottom of the mixing vessel and provided with radially extending mixing blades arranged in a plurality of planes. The mixing blades are preferably rectangular in cross-section and have a wedge-shaped taper or knife slope in the forward feed direction to impart an axial flow to the material being processed as the blades pass therethrough. The material being machined is loose when the slope is facing upwards, and is compacted when the slope is facing downwards. [0003] The body of the mixing blade is formed in one piece and is made of a relatively so...
