  • Patent number: 10265669
    Abstract: A mixing container 1 with a top filling opening 5, with a connection flange 9, 9.1 which projects outward in the area of the top filling opening 5 in a radial direction for connecting the mixing container 1 to the mixing head of an industrial mixing machine and with a bottom discharge 13 that can be blocked and opened comprises a mixing receptacle 3, 3.1 forming the hollow chamber 4 of the mixing container 1 and with a wall 18, 19 encompassing its hollow chamber and flexible in a radial direction and comprises a container frame 2 holding the mixing receptacle 3, 3,1 and with the connection flange 9 and the discharge 13. The container frame 2 holds the mixing receptacle 3, 3.1, in such a manner that its wall 18, 19 surrounding the hollow chamber 4 is at least partially accessible in the circumferential direction for bringing about a deformation of it in the radial direction.

  • Patent number: 9968897
    Abstract: This mixing machine comprises a mixing head that attaches to a container, forming a closed mixing receptacle. The head is pivotably supported in a frame such that the closed mixing receptacle can pivot to perform the mixing. The mixing head also has a rotationally driven tool which cleans the bottom of the head, supplying a low-energy transport stream for material to at least one second tool carried by the head. The second tool performs the mixing and is located inside the movement path of the bottom-cleaning first tool. The first tool has a scoop positioned in the direction of rotation of the tool with its edge facing in the direction of rotation and outward in the radial direction. The first tool comprises a first scoop section, a second, wall-cleaning scoop section and a recess open toward its closure more remote from the wall through which the second tool passes during rotation of the first tool.

  • Patent number: 9950301
    Abstract: A mixing machine 1 comprising a mixing head 3 having element(s) for connecting to a receptacle to form a mixing container. The mixing head 3 is pivotably supported in a frame 2 such that the mixing container can pivot for the mixing process. The mixing head 3 has at least one rotationally driven mixing tool whose drive shaft 23 extends through the wall of the mixing head 3. The mixing head 3 has a double wall with a perforated inner wall 8. The perforations form a fluid path from the chamber surrounded by the inner wall 8 to the intermediate wall chamber 10. The intermediate wall chamber 10 is connected to a pressure adjustment device for adjusting the pressure. A flexible liner 15 is arranged in the mixing head 3 on its inner surface, which liner 15 can be fixed to the inner wall 8 of the mixing head by applying a vacuum.

  • Patent number: 8979354
    Abstract: A mixer 1 for thermal treatment of a material for mixing consisting of solid particles comprises a mixing vessel 2 for admitting the material for mixing. The vessel 2 has at least one thermal medium channel that with its surface gets at least partially in contact with the solid particles to be heat-treated, through which thermal treatment media are fed when the mixer 1 is in operation. Additionally, the mixer 1 has available a device for circulating the material for mixing found in the container 2. The container 2 is turnably supported about an axis R that penetrates the two front sides 7, 20. A motorized drive 17, 18, 18.1 serves as a circulating device to turn the container 2.

  • Patent number: 8678639
    Abstract: A mixing machine 1 includes a mixing head 3 displayed with one or several elements 12 for connecting the same to a container 5 containing a mix to form a closed mixing receptacle containing the mix. The mixing head 3 is mounted pivotably relative to a frame 2 in such a way that the mixing receptacle formed from mixing head 3 and container 5 is pivotable to execute the mixing process. The mixing machine 1 further includes a device for producing a mix stream and at least one rotary-driven mixing tool interacting in the mix stream. The mix-stream-producing device is designed to produce a low-energy primary mix-stream as a feed stream for supplying the mix contained in the mixing receptacle to the at least one mixing tool W2 disposed in the mixing head 3 interacting in the primary mix-stream produced by the mix-stream-producing device.
