摘要:
Method for treating known catalyzed hydraulic mixtures for making non polluting manufactured articles which can be freely stocked, comprising the following phases: a) a shaping phase of the respective mixture in blocks having a regular or irregular geometrical form, for example a parallelepipedic form, a plate-like form or similar, b) a pressing phase of said blocks under a high pressure which is equal to or higher than the working pressure of road rollers by the construction of roads, and c) a block curing phase of, for example, about 60 days. The obtained manufactured articles can be used in their actual form, that is for the building of walls and masonries, for forming foundations or yard floorings, for building temporary or final embankments, as for example artificial reefs. The obtained manufactured articles can also be crushed and utilized as inert materials as replacement of the natural or quarry aggregates.

Catalyzed hydraulic mixtures containing inert materials which are mainly, preferably fully, constituted by inert materials recovered from building demolition processes, and being ground and granulometrically separated to a range of 0.05-30 mm, and used in an amount from 20% to 60% by volume, blast furnace slags and/or blast furnace ashes, having a granulometry in a range of 0.05-3 mm used in an amount from 10% to 25%, ashes derived from burnt waste materials, for example urban waste materials or the like and comprising both heavy and light ashes with a granulometry in a range of 0.05-15 mm, used in an amount from 10% to 70%, wherein the catalyzers are selected to provide a basic environment with at least a pH 11, thereby the included salts can be recrystallized, with a consequent confinement of the polluting substances included in the slags. With said mixtures can be made non polluting articles.

A method and device for separating light fractions, in particular longitudinally extending wood (27), from granulometrically sieved rubble mixtures (9), in which on a vibrating panel (3), are arranged a plurality of partition walls (7) defining channels (8) for orienting and longitudinally guiding the rods (27), where is provided a variable size composite opening (13) allowing to from a first curtain (21) comprising the heavy fractions and smaller light fractions, and a second curtain (24) formed by light paper and larger synthetic sheet material fractions and wood "rods" (27) or only by the latter. The subject separating device (1) can be used as an end separating stage, and can practically provide a recovery of the actual end weight due to the residual presence of the light fraction comprising the wood rods (27) to prevent any disposal of in disposal sites, since the rods (27) are cleaned and accordingly can be reused. Moreover, the end inert material, after the above mentioned operation, is cleaner and has an improved value.

摘要:
A method, a device and a plant for cleaning irregular pieces consisting of different materials, for example cast iron pieces with parts of compressed coal dust sticking thereon and coal pieces made of compressed coal dust with parts of a contaminating film adhering thereon, wherein the cleaning of both materials is carried out in only one cleaning device (1) comprising a cleaning jacket (2) which has a substantially horizontal longitudinal axis (3), is rotatable in both directions of rotation, is pivoted (4) in order to swing in the vertical longitudinal plane, and is provided with cleaning tools (12, 12A) which are fastened to said cleaning jacket (2) along jacket generating lines or helicoidal lines. Said cleaning tools (12, 12A) have two geometrical different operative sides (13, 14) in order to form an active side for each of both materials to be cleaned when rotating in an associated direction of rotation.

A system for recovering anodes used in smelting baths for making aluminium comprises: b) a drive unit rotatable about a vertical axis and including an articulated robot arm having gripping means for gripping the anodes, and a tool for breaking the bath block or anode slags and carbon ingots, b) a workstation for successively breaking and removing the bath block and carbon ingots, and c) a conveyor belt assembly for separately unloading the bath and carbon components removed from the anode, and d) an anode taking station for taking up the anodes to be processed and an unloading station for unloading the recovered anode metal constructions.
摘要:
A method and a mill (1) or crushing station (A) for crushing rubble, wherein the crushed material fills the mill discharging hopper (9) for a height (H1) which is higher than the height (H) of a hopper discharging opening (11) so that a continuous material plug (6) is formed which closes said discharging opening (11). The discharging means (2; 17) can be either integrated into the mill discharging hopper (9) or form a separated discharging device (2) which is associated to the mill (1). In operation the plug (6) is continuously removed from the plug bottom and fed to the plug top so that said continuous plug prevents the formation and exhausting of dust. The known dust separation chambers are thus superfluous.

In a preferred embodiment said two components consist of tire chips and aggregates, obtained from building rubble, whereas the binder is cement. The damping structures are realized as diaphragm walls or foundations, for example for roads, railroads, industrial sheds and the like.
