摘要:
The present invention generally relates to mixing systems for concrete, mortar, grout or other aggregate and more specifically to portable single person carries mixing systems capable of mixing concrete or other aggregates uniformly, rapidly and with less waste. In accordance with one aspect of at least one embodiment of the present disclosure, a portable aggregate mixing system is disclosed comprising a mixer with a power source and mixing tines and a mixing container comprising sidewalls, a bottom surface, a front and back wall and an open top. The mixing system coordinates the mating of the mixing blades or tines of a mixer with the surface characteristics of a customized or standard mixing tub or wheelbarrow to ensure uniform mixing of aggregate occurs quickly with minimal waste.

A method for continuously mixing a borehole fluid such as cement includes using a measurement of the solid fraction of a cement slurry as it is being mixed to determine the ratio of the solid and liquid components to be added to the slurry. A system for mixing the includes a liquid material (water) supply including a flow meter; a solid material (cement) supply; a mixer which receives the liquid and solid materials and includes an output for delivering materials from the mixer to a delivery system; a device for measuring the amount of material in the mixer; and a flow meter in the output; wherein measurements from the flow meters and the device for measuring the amount of material in the mixer are used to control the amount of solid and/or liquid material added to the mixer.

Method and system for concrete wash-out water re-use, wherein an apparatus such as a mixing truck (1) is washed out and sludge (2) water re-used. The invention comprises providing sensors (11), in a communication system connected with a control center (10), for determining amount of retarder (4) used and resulting sludge water/concentration. The data is analyzed such that overdoses or insufficient doses of retarder are minimized or prevented. Warnings or corrective signals can then be sent by the control center (10) if needed.

摘要:
A method and apparatus for automatically regulating the plasticity of ceramic material by means of addition of water, vapor (or steam) or dry substances to the mixer of a production chain which includes a mixer and an extrusion press. The plasticity of the material in the pressing head of the extruder and the power consumption of the mixer are measured and provided as regulating signals to a cascade regulator. The cascade regulator includes a primary regulator and an auxiliary regulator which are preferably equipped with constant regulators. The regulator associated with the primary regulator system includes an integrating portion and an output signal from the cascade regulating system is utilized for controlling a dosing device for a dosage type addition of water, steam or dry substances to the mixer.

A drum control system includes a mixture sensor and a controller. The mixture sensor is configured to be positioned within a drum to engage with drum contents to facilitate acquiring drum contents data indicative of a property of the drum contents. The controller is configured to control a drive system to rotate the drum at a first, unmixed speed following receipt of the drum contents by the drum where the drum contents including ingredients of a concrete mixture; acquire the drum contents data from the mixture sensor and monitor the property of the drum contents as the drum rotates; and control the drive system to rotate the drum at a second, mixed speed in response to determining that the property of the drum contents indicates that the ingredients have been sufficiently mixed.

A vehicle includes a chassis, an engine, a drum assembly, and a control system. The drum assembly includes a drum configured to receive drum contents and a drive system coupled to the drum. The drive system is configured to rotate the drum to agitate the drum contents. The control system is configured to operate the drive system at a drive speed; receive data comprising at least one of (i) a drum speed command from a remote monitoring system, (ii) a signal from a mixture sensor configured to acquire mixture data indicative of a current property of the drum contents, (iii) the current property of the drum contents from the remote monitoring system, and (iv) an initial property of the mixture from at least one of a batching system, the mixture sensor, and a user input device; and adjust the drive speed of the drum based on the data.
