The present invention relates to a granulating and/or agglomerating tool for a granulating and/or agglomerating device with a fastening shaft and a substantially disk-shaped element with a diameter d which is fastened thereto and has an upper surface, a lower surface and a circumferential surface connecting the upper and the lower surface. In order to provide a granulating and/or agglomerating tool for a granulating and/or agglomerating device and a corresponding granulating and/or agglomerating device and a method for granulating or agglomerating with which the desired granulating or agglomerating result can be obtained very much faster and above all with a significantly finer granulated material with a significantly higher yield in the range of from 0.1 to 0.8 mm, it is proposed according to the invention that the circumferential surface exhibits a plurality of essentially V-shaped grooves running parallel to the axis of the shaft.

A dual speed manual stand mixer. The mixer has a bowl with a cover fixed to the bowl. The cover includes a ring selectively mounting to the rim of the bowl, and a turntable mounted for rotation within the ring. Multiple whisks extend downward from the turntable into and within the bowl. Gearing is provided to cause both rotation of the turntable, as well as rotation of each individual whisk. A transmission is also provided to selectively connect a manual crank arm in one of two possible limit positions. The gearing ratios differ between these two position to thus drive the turntable and whisk rotation at two different speeds.

A liner element for lining a vertical grinding mill agitator including one or more primary mounting portions configured to releasably mount the liner to a shaft of the agitator; and one or more secondary mounting portions configured to releasably mount one or more wear members to the liner. A liner segment including the liner element and at least one wear member is also disclosed.

The invention relates to a construction material mixer, in particular an asphalt or concrete mixer, consisting of a container (1) having at least one driven shaft (5) to which mixing arms (6) carrying blades (12) are fastened at intervals, the blades (12) being at a distance from the inner wall of the container (1), the mixing arms (6) being divided into an inner part (11), which is connected to the shaft (5), and an outer part (13), which carries the blades (12), and both parts being connectable to each other by means of an adjustable connection device (22). The invention is based on the fact that the connection device (22) is a snap connection device. A particular embodiment and a rapid blade replacement method are described.

A scraping and/or mixing assembly for a mixing apparatus for food, pharmaceutical or cosmetic products, including a mixing arm element and at least one respective scraping and/or mixing element attached to each other by a quick-release attachment assembly including a support element and a body element connected to the scraping and/or mixing element. The support element and body element are attachable to each other by a first releasable clamping assembly including a first retaining element movable between a clamping position, clamping the support and body elements to each other, and a releasable position. The first releasable clamping assembly includes a first resilient clamping element made integral with one of the body element and the support element and movable between a rest position, wherein it engages the first retaining element to keep it in the clamped position, and a stressed position, wherein it disengages the first retaining element to release it.

A mixing device includes a holder and a mixing element. The mixing device has a central axle and rotates in relation to the holder about an axis of rotation which coincides with the central axle. The mixing element includes an axle body and a plate-shaped mixing body. The mixing element further includes a plate-shaped wearing body, and connecting elements. The shanks of the connecting elements respectively extend through or at least into associated mutually aligned first holes in the wearing body and second holes in the mixing body. The mixing body is provided with recesses in the middle of which the associated second holes are provided, wherein parts of the wearing body that surround the first holes extend within the recesses.
