Abstract: A granulator device (1) for the treatment of powdered products comprises at least one closed container (2) forming a chamber (3) for treatment of the products; filter elements (4, 5) projecting into the treatment chamber (3), the filter elements (4, 5) comprising at least one multi-layer filtering wall (5) through which at least one fluid current can pass; and powder removing parts (6; 7, 8, 9, 10, 11) designed to diffuse at least one service fluid directed towards the filtering wall (5); the powder removing parts (6; 7, 8, 9, 10, 11) comprising at least a first arm (10) mobile relative to the filtering wall (5) and fitted with a set of first diffuser nozzles (7), the set of first nozzles (7) being positioned on the first arm (10) in such a way that it gradually covers the length of the surface of the filtering wall (5), as the arm (10) moves, diffusing the service fluid so as to free the filtering wall (5) of the powders trapped in it.

Abstract: The device for controlling the movement of skips in machines for granular or powder and liquid treatment machines is of a type where the skip is separable from an overlying treatment chamber, to which it is sealingly couplable and which skip is rotatably supported by a horizontal-axis pivot (2) on a frame (3) mobile on wheels (4). The device comprises at least one hydraulic cylinder (5) provided with a piston (15) comprised between two chambers (25, 35), which cylinder (5) bears a rotating organ (45) coupled in rotation with the pivot (2). The two chambers (25, 35) are interconnected with an interpositioning of at least one regulation valve (6) which on command can regulate the flow of a hydraulic fluid in two directions and can also totally halt the flow.

Abstract: A device for forming and coating solid particles comprises a rotating disc interiorly defining a process chamber and which can assume a rest position in which is interiorly closes the chamber and a working position in which it affords an annular passage through which a process gas is allowed to enter the chamber. A rotary hydraulic motor commands rotation of the disc; two hydraulic linear actuators perform vertical displacement of the disc. Both the motor and the actuators are located immediately below the disc. An especially advantageous use of the device is as a granulator or as a coater of granules.

Abstract: The plant for treating powders or granules enables a considerable simplification of the operation of cleaning the filters, and a more efficient centering of the basket container, and includes a tubular casing coupled in a detachable manner to a cover and a base structure. The tubular casing may be rotatable around a horizontal axis on opposing aligned appendages, and the base structure may include a basket resting on a trolley which can be lifted in a guided manner to couple with the bottom edge of the casing. The plant may be used in a wide variety of industrial applications, in particular in the chemical, food and pharmaceutical industries.
