摘要:
Machine and method for compacting ceramic powder (CP); a layer of non-compacted ceramic powder (CP) is conveyed in a feed direction (A) through a compacting device (2); downstream of the compacting device (2) there is positioned a detection device (8) which detects the density of the layer of compacted ceramic powder (KP); the quantity of ceramic powder (CP) fed to the compacting device (2) is varied in time as a function of what is detected by the detection device (8) to thus regulate the density of the layer of compacted ceramic powder (KP).
摘要:
A method and machine (2) for the surface decoration of a basic article (3) comprising ceramic material and having a surface (4); a printing assembly (16) applies an adhesive material (17) digitally and selectively onto a defined area (18) of the surface (4); a treatment assembly (20) deposits a powder material (21) digitally and selectively in the defined area (18); and the powder material (21) in excess arranged on the basic article (3) is removed.
摘要:
A kiln and method for firing basic ceramic articles (BC) ; the kiln comprises a conveying device for conveying the basic ceramic articles (BC) along a given path through a firing chamber (12), in which the basic ceramic articles (BC) are heated, a cooling chamber (16), in which the basic ceramic articles (BC) are cooled so as to obtain ceramic products (CP); and an extraction device (25) adapted to generate two gas flows (F, G) in the firing chamber (12); the gas flows (F, G) come from two opposite ends of the firing chamber (12) and meet in the extraction device (25).
摘要:
A radiating heating module for a tunnel kiln for continuous-cycle firing of ceramic products such as tiles, slabs, bricks, sanitary appliances and the like, which advance on a roller plane located internally of the tunnel, in which tunnel the heating means are of a radiating type, characterised in that it comprises a pair of parallel radiant tubes, each comprising at an end thereof a free flame burner, combustion gases of which flow along the tube, and at an opposite end thereof a heat exchanger crossed by the combustion gases, the two radiant tubes being reciprocally orientated in an opposite direction so that the end of the tube of each pair comprising the burner is adjacent to the end of the other tube of the same pair comprising the heat exchanger, the comburent air conduit of the burner of a tube comprising the adjacent heat exchanger located at the end of the other tube.
