摘要:
A measuring apparatus (1) for concrete materials, comprising an aggregate hopper (3) as aggregate feed means for feeding fine aggregate (2) as aggregate, a water supply pipe (4) as water supply means, an aggregate measuring bin (51) for storing and measuring the fine aggregate (2) supplied from the aggregate hopper (3), a measuring tank (5) for storing the fine aggregate (2) supplied from the aggregate hopper (3) as water-immersed aggregate together with water supplied through the water supply pipe (4), a load cell (6) as water-immersed aggregate mass measuring means for measuring the mass of the water-immersed aggregate in the measuring tank, an electrode sensor (7) as water level measuring means for measuring the water level of the water-immersed aggregate in the measuring tank (5), and a water level holding device (8) as water level holding means for holding the water level of the water-immersed aggregate in the measuring tank (5) at a desired water level.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung eines hydraulisch förderbaren Feststoff-Flüssigkeits-Gemisches. Erfindungsgemäß werden die Gemischkomponenten in einem Mischer mit einer ersten Flüssigkeitsmenge zu einer mischbaren, aber noch nicht verpumpbaren Suspension verarbeitet und anschließend nach empirisch ermittelten Zusammenhang zwischen den rheologischen Mischungseigenschaften und der Feststoffvolumenkonzentration im Mischer eine zweite Flüssigkeitsmenge zudosiert und eine verpumpbare Mischung bei restflüssigkeitsfreier Abbindung hergestellt, wobei in einem nachfolgenden Reaktor gegebenenfalls eine dritte Flüssigkeitsmenge bei Überschreiten des zulässigen Druckverlustes nachdosiert wird.
摘要:
A mobile system and process for manufacturing cement additives and/or concrete admixture products comprise tanks (14, 16, 18, 20, 22) each containing a different raw material. Pumps (24, 26, 28, 30, 32) operate to transfer the raw materials into a blender (50) to produce a cement additive or concrete admixture for dispensing at the destination site. The frame (12) can be placed upon or attached to wheels, as in a truck or trailer frame, and the tanks may also be placed on or secured to the truck or trailer frame. A preferred skid-mounted system (10) comprises pumps (24), valves (34), meters (104), and a computer processor unit (70) which can control the equipment and permit adjustments to be made at the destination site. Tanks of raw materials may be transported to a destination site together with or separately from the frame-mounted equipment, and finished products can be blended and adjusted on site by computer-controlled operation in response to input parameters such as the quality of limestone, cement, aggregates, water, and also in response to desired product blends, performance features, etc.
摘要:
The invention relates to a method for treating material mixtures, which contain a coarse component (3) and a predominantly coherent fine component (4), whereby both the material mixture (2) and an aggregate (5) are fed to a homogeniser-separator (12) in continuous streams (11, 23). The homogeniser-separator (12) uniformly blends the aggregate (5) and the material mixture (2), in order to convert the fine component (4) of the material mixture (2) into a condition, in which said fine component (4) can be separated from the coarse component (3). The continuous feeding of the material mixture (2) and the aggregate (5) into the homogeniser-separator (12) ensures a homogenous, thorough blending of the aggregate (5) and fine component (4), in such a way that the separation of the coarse component and the fine component can take place immediately in the same device. Said method allows material mixtures (2) to be treated without the production of waste in a single method step, producing two utilisable products.
摘要:
Zur Schaffung einer einfach und kompakt aufgebauten Dosiervorrichtung für flüssige Farbkonzentrate zur Putzeinfärbung, mit einem Gehäuse (4) zur Aufnahme eines Vorratsbehälters (7) des zu dosierenden Farbkonzentrats, einer verstellbaren Dosierpumpe (9) und einem Durchflußmeßgerät (25) zur Erfassung der Durchflußmenge an Anmachwasser, wird eine Steuereinheit (15) vorgeschlagen, in der wenigstens eine Kennlinie (A,B,C,...) für ein vordefiniertes Farbkonzentrat-/Anmachwasser-Verhältnis festgelegt ist.
摘要:
A process for adjusting the level of water or water soluble additives in aqueous-based powder injection molding compounds for the purpose of recycling scrap material, controlling shrinkage or rehydrating dry feedstock. Depending on the objective, the process may require material granulation equipment, equipment for the addition or removal of water and mixing equipment. The molding compounds may be comprised of either recycled scrap material before being heat-treated or dry, virgin feedstock material.

摘要:
Ein Fahrzeug, vorzugsweise ein Fahrmischer (20), weist ein an den Fahrzeugrahmen (43) angebautes schwenkbares Förderband (21,22,23) auf, dessen Tragteil (26) um eine vertikale Achse (37) drehbar an einem Schwenkarm (33) gelagert ist, der seinerseits um eine vertikale Achse (49) schwenkbar an dem Fahrzeugrahmen (43) oder einer mit diesem verbundenen Konsole (44) gelagert ist. Das Tragteil (26) und der Schwenkarm (33) sind durch Antriebe verschwenkbar. Um die Manövrierfähigkeit zu verbessern und den Arbeitsbereich zu vergrößern, sind der Schwenkarm (33) und das Tragteil (26) an mit Verzahnungen (36) versehenen Drehkränzen (39,29) befestigt, deren diese lagernden ringförmigen Lagerkörper (40,31) an dem Fahrzeugrahmen (43) bzw. der Konsole (44) und dem Schwenkarm (33) befestigt sind. Die Antriebe bestehen aus angetriebenen Ritzeln oder angetriebenen Schnecken (35), die mit den Verzahnungen der Drehkränze (39,29) im Eingriff sind.
摘要:
Modular, containerised mixing unit (1) for mixing concrete, cement or mortar, whereby all components, still separated, are conveyed in one component container (2a,2b). The container may be provided with an independent power source, with support legs, wheels or train wheels and can be used at substantially any location. For coupling a component container (2a,2b) to the container (1) an integrated hoisting device or a hydraulically driven centring device (3a,3b) can be used.
