摘要:
The invention relates to a concrete mixer, in particular a free-fall mixer, in which the components of the concrete, in particular initially without water, can be intermixed by mixing elements by means of the rotation of a drum, wherein a vibrator is provided.The object of the invention is to make the mixing process easier and to save energy. This object is attained in that a vibrator which is switched on during the mixing process in order to reinforce it is disposed in the drum in the vicinity of the material to be mixed.

A concrete mixer comprising a main frame, a large bearing ring carried by the main frame, the ring supporting an outer barrel carrier for rotation, an inner rotary barrel of elastomeric material supported for rotation by said barrel carrier, the barrel carrier having a number of spaced fingers extending away from the ring, there being a flexible strap extending from each finger to the outer surface of the barrel, so supporting the barrel that its wall can be deflected from the outside to dislodge concrete which might adhere to the inner surface, and an elastomeric rotor supported for rotation within the inner rotary barrel.

The object of the present invention is to provide a device with a simple structure which can uniformly mix bulk materials.A device comprises a rotary shaft 6 to be rotated by a driving means 3, a container outer shell 7 fixed to the rotary shaft 6 to tilt relative to the rotary shaft 6, and an inner shell 9 fixed inside the container outer shell 7. Bulk materials are put into a receiving space 13 formed between the container outer shell and the inner shell and are then agitated and mixed.

A continuous mixer (10) comprises an elongated mixing container (11), which has an inlet opening (14) at one end for feeding in the basic components to be mixed and which encloses a mixing space (12), which merges at the other end into a discharge region (22) for the delivery of the mixed product, and in which mixing container (11) there is arranged a mixing tool (13), which is rotatable about an axis (41), is driven by a drive (18, 40) and mixes together the basic components fed into the inlet opening (14) and at the same time transports them to the discharge region (22). In such a mixer, improved control of the mixing conditions is achieved by an adjustable discharge opening (19) adjustable in size being arranged between the discharge region (22) and the mixing space (12).

The invention relates to a concrete mixer truck having a rotatably driven mixer drum, particularly a drum provided with interior mixing elements, and a hydraulic system as a drive source for the mixing process.It is intended to enhance the effect of the mixing process by transmitting vibration energy to the mixture materials. To this effect, a vibration generator is included in the hydraulic system in such a manner that pressure pulses generated in the flow of the hydraulic fluid are superimposed on the mixing movement in the form of vibrations. This superposition effect may be achieved with respect to the rotation of the drum and/or with respect to the movements of a separate mixing tool.

The present invention relates to a process for producing a foam ceramic comprising the steps: producing an aqueous suspension of a first mineral raw material; foaming the suspension with air while adding a foaming agent and a binder to form a light foam; mixing the light foam with a powder or slip of a second ceramic raw material to form a heavy foam; pouring the heavy foam into a mold; drying the molded heavy foam in the mold to form a solid foam; and firing the solid foam in the mold to form the foam ceramic.
