摘要:
An example apparatus for additive manufacturing can include a supply of dry cement powder (702) having an individually controllable outlet (704); a supply of a dry mineral filler (706) having an individually controllable outlet (708); a supply of a curing accelerator (712) having an individually controllable outlet (714); and a supply of water (716) having an individually controllable outlet (718). A batch mixer (722) can receive and mix a controlled amount dry cement powder from the supply of dry cement powder, a controlled amount of dry mineral filler from the supply of dry mineral filler, a controlled amount of curing accelerator from the supply of curing accelerator, and a controlled amount of water from the supply of water, thus forming a batch of cementitious material. A pump (750) can be connected to the batch mixer to pump the cementitious material. A delivery hose (150) can be connected to the pump to deliver the cementitious material pumped by the pump from the batch mixer. A printhead (502) can be connected to an outlet of the delivery hose. The printhead can be positionable in three-dimensional space.

Portable metering and mixing apparatus includes a trailer having a hopper thereon divided into two compartments, one compartment for sand material and another compartment for cementitious material. Screw conveyor assemblies, or auger assemblies, receive the materials and convey the materials to a mixer assembly. Different embodiments are disclosed. One embodiment includes a mixing chamber aligned with an auger assembly and to which the mixing chamber materials are fed directly. Another embodiment discloses a separate mixer assembly to which the materials are conveyed by a pair of auger assemblies.

The present invention aims to evenly and surely knead a concrete material comprising less water amount. Concrete material layer entered into a kneading tank is cut in an up-and-down direction and divided into a plurality of layer sections arrayed side by side along a right-and-left direction,, and one of the divided layer sections is piled up another one of the divided layer sections in the up-and-down direction, then the piled up concrete layer sections are compacted, in other words are pressed in the up-and-down direction and extended in a horizontal direction, and further these steps are repeated.

A multiple stage mixer including a pair of mixing chambers in communication with each other for the transfer of material therebetween and a rotary mixing element in each chamber movable on a path overlapping into the adjacent chamber in selected normal phase relation with respect to the mixing element therein. A source of motive power for rotatively driving said mixing elements and control means for rendering said motive power source ineffective when said mixing elements are out of said normal phase relation with each other is provided in order to prevent damage to the mixer in the event the phase relation between the mixing elements becomes abnormal.

A CAVITATION ELEMENT FOR INDUCING CAVITATION IN, FOR EXAMPLE, A WET CONCRETE MIX. THE ELEMENT HAS A SMOOTH UPSTREAM PROFILE AND A BLUFF DOWNSTREAM PROFILE WITH FORMATIONS ON ITS UPPER SURFACE WHICH INDUCE A CORRUGATED SHAPE TO THE ENVELOPE OF THE CAVITATION IMMEDIATELY DOWNSTREAM OF THE BLUFF PROFILE. AN INLET WITHIN THE ELEMENT COMMUNICATES WITH A NUMBER OF APPERTURES OPENING INTO THE BLUFF PROFILE WHEREBY A JET, OR JETS, OF FLUID OR OTHER ADDITIVE ARE SUPPLIED THROUGH THE APPERTURES INTO CAVITATION INDUCED BY THE BLUFF PROFILE.

A container and dispensing method for mixing and dispensing a set of ingredients. The container includes a tube having a dispensing end and a filling end, the filling end being sealed by a first plunger. The container includes a second plunger between the dispensing end and the first plunger that separate the interior into a first cavity and a second cavity, each cavity holding at least one ingredient. The second plunger includes a breakable membrane portion. A mixing apparatus is inserted through the dispensing end, pierces the membrane portion, and urges the second plunger towards the first plunger, causing the ingredients between the plungers to flow through the pierced membrane portion and combine. The mixing apparatus feature expandable flanges, and may be driven with a rotating force to mix the combined ingredients within the tube. The first plunger is then used to dispense the mixture through the dispensing end.

A concrete batch mixing system and method are disclosed that enable the batch master to measure and control both the water and cementitious ingredient feeds in relation to each other so as to be able to blend the two ingredients in a known, selected, adjustable and repeatable manner, and to agglomerate these ingredients in a counter-rotating twin screw mixing apparatus for use in the preparation of batches of mixed concrete in a concrete batching process.
摘要:
The invention relates to an apparatus for treating solid, liquid and/or gaseous materials with an activator with at least three coaxially arranged paddle rows (3, 4, 5) which are drivable in a contrarotating manner with beater paddles (6) having set angles of incidence (6), with the circumferential speed of the outer paddle rows (3, 4, 5) being between 70 m per sec. and 160 m per sec. In order to increase the extent of the achievable activation of the particles of the material and thus the performance of the apparatus and the quality of the manufactured products it is provided that the width (b.sub.1, b.sub.2, b.sub.3) of the paddle rows (3, 4, 5) decreases outwardly by at least 2%, preferably by at least 5% and maximally by not more than 10%.

A mixing bucket holder device holds a mixing bucket stationary while contents of the mixing bucket are being mixed. The device includes a support having a top wall, a bottom wall and a perimeter wall coupled to and extending between the top wall and the bottom wall. The top wall has a depression therein for receiving a mixing bucket. The depression has a lower wall and a peripheral wall coupled to and extending upwardly from the lower wall. The perimeter wall of the support has at least one opening extending therein for receiving feet of a user. A plurality of wheels is coupled to the bottom wall. A retaining assembly is coupled to the depression. The retaining assembly engages the mixing bucket and maintains the mixing bucket in a stationary position while contents of the mixing bucket are mixed together.
