A device stores, mixes, and applies polymethylmethacrylate bone cement. The device comprises a first container for a first pasty component of the bone cement, a dispensing plunger arranged in the first container such that it can be shifted and serves for pressing the content of the first container out of a dispensing opening, a mixing facility for mixing the content of the first container, whereby the mixing facility is arranged in the first container and the mixing facility can be moved in the first container from outside for mixing, and at least one second container for at least one second component of the bone cement is arranged in or on said first container. The second container can be opened, such that the contents of the first container and second container can be mixed with each other in the first container, whereby at least a boundary surface of the first container is formed by a mobile volume compensation element.

A method for producing a rubber composition containing a rubber wet master batch has a masticating process. The masticating process comprises step 1 of charging the rubber wet master batch into an enclosed kneading chamber that has a stirring rotor showing a rotation speed controllable automatically through a control unit and that is capable of detecting and outputting an internal temperature, step 2 of setting a first control time and a first target temperature in the control unit, and step 3 of stirring the inside of the kneading chamber while making a PID control for adjusting an actually measured temperature in the kneading chamber to the first target temperature through the control unit on the basis of information on the actually measured temperature and the first target temperature, thereby automatically controlling the rotation speed, until the first control time elapses after the completion of the two steps.

The present disclosure discloses a meshing-type rubber internal mixer and a working method thereof. The meshing rubber internal mixer includes a frame mechanism, a mixing mechanism, and an unloading mechanism. The mixing mechanism is on the upper side of the unloading mechanism. The mixing mechanism and the unloading mechanism are in the frame mechanism. An internal mixing chamber is of a closed structure through first automatic telescopic plates and second automatic telescopic plates. The gap between a first meshing-type rotor and a second meshing-type rotor is small, a material is compressed to enter the space between the first meshing-type rotor and the second meshing-type rotor to be extruded with an internal mixing chamber wall. The material is flaky in the internal mixing chamber, so that the material produces great strain deformation, thereby achieving excellent dispersing and mixing effects.
