Abstract:
A continuous mixing plant suitable for manufacturing a mixed material continuously and in a short time by only supplying necessary materials continuously while weighing them and allowing the materials to drop under self-weights; comprising a continuous weighing/supplying means for keeping on supplying at least two kinds of materials to be mixed while weighing them individually and a mixing box for mixing materials supplied from the continuous weighing/supplying means; wherein a mixing box device is provided with a plurality of shape-changing passages having their cross-section shapes continuous changed from their inlets toward outlets and with a merge/division means provided between inlets and outlets of respective shape-changing passages and adapted to merge and divide materials passing through respective shape-changing passages, and is characterized in that mixing is effected by continuously charging respective materials and passing them through respective shape-changing passages toward outlets under self-weights.
Abstract:
Apparatus for the rapid production of concrete comprising a grout slurry forming device, a cyclonic mixer for aggregate and a weighing device for feeding weighed amounts of aggregate to the cyclonic mixer. The slurry forming device including, subjecting fine particles in a liquid to the action of one or more rotating disc shaped blades, arranged to create within the slurry alternating areas of high and low pressures, thereby breaking up agglomerations. The cyclonic mixer includes, a hopper in which at least two conveyors simultaneously transport aggregate streams tangentially into, in opposite directions inducing helical mixing paths. The weighing device including, an aggregate weighing means wherein a number of aggregate storage bins selectively releases aggregate onto a variable speed controlled conveyor. Intimately mixed concrete being formed from the simultaneous release of the grout slurry into the cyclonic mixer combining with the mixing aggregate.
Abstract:
An apparatus for the preparation of colored materials in powder form for the manufacture of ceramic tiles, which comprises a mixer constituted by an upper cover (6) connected to the supply line (3) of the base material and by a mixing chamber (5); a vibrating frame (9) located between upper cover and mixing chamber; a perforated baffle fixed to the vibrating frame, the vibrating frame is connected with seal to the mixing chamber. The apparatus is provided with a system for the generation of an operating vacuum pressure in the upper cover and an injection system of the colorant at the base of the mixing chamber. The apparatus of the present invention produces a method for the preparation of colored materials in powder form for the manufacture of ceramic tiles, wherein the atomized and/or granulated ceramic material of uniform particle size, containing or not containing coloring substances, is fed uniformly into a chamber under vacuum pressure with respect to the mixing chamber connected to said chamber through a vibrated perforated baffle; coloring particles are injected at the base of a mixing chamber; the atomized and/or granulated ceramic material falls by gravity and is sprinkled inside the mixing chamber; and mixing in gaseous phase of the atomized and/or granulated ceramic material with the rising current of coloring particles.
Abstract:
A kneader adapted to knead an object material mechanically with a high efficiency by passing the object material by a free fall thereof owing its own weight through modified passages the cross-sectional shape of each of which varies gradually in the lengthwise direction thereof, wherein a plurality of elements (11a, 11b) having a plurality of substantially vertically extending modified passages (12, 13) which are provided with inlets (12a, 13a) and outlets (12b, 13b) at one end portion and the other end portion respectively of each thereof, and which vary in cross-sectional shape continuously from the inlets to the outlets, are joined together and set so that the modified passages extend substantially vertically, the directions in which the modified passages (12, 13) extend being changed from one another so that straight through passages extending from the inlets to the outlets do not exist in the elements.
Abstract:
A kneading device that makes possible the three-dimensional kneading of a fluidic material to increase the kneading efficiency and that has a construction suitable for manufacture by resin molding of elements constituting the main section of the kneading device, the kneading device comprising a device body (30) having a plurality of varied passages (1, 2) whose sectional shapes are varied along the longitudinal direction, a material force-feeding means (20) connected to the inlet side of the device body (30) for force-feeding the material to be kneaded into the varied passages, and confluence and division means (3, 4) interposed between the inlet and outlet sides of the device body for causing the confluence and division of the material to be kneaded flowing through the varied passages, at least one of the varied passages being such that the cross-sectional area is progressively varied from the inlet side toward the outlet side of the device body. In that case, there may be added a material force-feeding means by which the material to be kneaded is pressed and fed in.
