Abstract: Micrometric separator (1) for biomasses (100) in particles, of the type including a first crushing stage (2) wherein particles are introduced dispersed in a conveying fluid bed, and a first conveyor for conveying the particles in the fluid bed. The first crushing stage (2) has a first crushing chamber (5) for reciprocal collisions of particles, that has a first revolving disc (7) provided with first members (9) for generating a turbulent flow in the fluid bed, and a first contrast body (8), in front of the first revolving disc (7), as well as one or more outlets (22) of the fluid bed, the first contrast body (8) being provided with an inlet (6) having an inflow section with the axis substantially incident to the first revolving disc (7).

Abstract: Micrometric separator (1) for biomasses (100) in particles, of the type comprising at least one first crushing stage (2) wherein said particles are introduced dispersed in a conveying fluid bed, and first means (110) for conveying said particles in said fluid bed. The afore said first crushing stage (2) comprises a first crushing chamber (5) for reciprocal collisions of particles, that has at least one first revolving disc (7) provided with first members (9) for generating at least one turbulent flow in the fluid bed, and at least one first contrast body (8), in front of the first revolving disc (7), as well as one or more outlets (22) of the fluid bed, the first contrast body (8) being provided with at least one inlet (6) having an inflow section with the axis substantially incident to the first revolving disc (7).

Abstract: An apparatus for mechanical processing of materials in the dry state is of the type having a casing, within which are set a plurality of rollers and at least one diffuser and/or contrast element for the plurality of rollers. The casing likewise has at least one input section and at least one output section for the materials. The rollers are arranged around the diffuser and/or contrast element so as to define, for each roller, a gap between the diffuser and/or contrast element and the side surface of the roller, and in that it comprises a drive for setting in rotation the diffuser and/or contrast element with respect to the plurality of rollers and/or for setting in rotation at least one roller, or the entire plurality of rollers, with respect to the diffuser and/or contrast element.

Abstract: An apparatus (1) for mechanical processing of materials (7) in the dry state is of the type comprising a casing (2), within which are set a plurality of rollers (3) and at least one diffuser and/or contrast element (4) for said plurality of rollers. The casing likewise has at least one input section (5) and at least one output section (6a, 6b) for the materials. The apparatus is characterized in that the rollers (3a, 3b) are arranged around the diffuser and/or contrast element so as to define, for each roller, a gap (d) between the diffuser and/or contrast element and the side surface of the roller, and in that it comprises means for setting in rotation the diffuser and/or contrast element with respect to the plurality of rollers and/or for setting in rotation at least one roller, or the entire plurality of rollers, with respect to the aforesaid diffuser and/or contrast element.

Abstract: A longitudinal micrometric separator for the classification of solid particulate materials comprising an outer casing having an inflow opening and an outflow opening for the particulate material, a collection chamber at the bottom, as well as a sliding support for the particulate material extending substantially along a longitudinal drawing axis, in which the material is conveyed in the direction of the aforesaid longitudinal axis by a forced fluid flow. The sliding support comprises at least one first inclined wall, lying in a plane parallel to the drawing axis, and at least one dropping channel with axis parallel to the drawing axis and connected to a side end of the same inclined wall, the other side end of the inclined wall being set at a distance from the internal surfaces of the casing.

Abstract: The separator device comprises a vertical, cylindrical container (4), provided at the bottom with a rotary discharge valve (9) and provided with a duct (5) which opens into its top portion and is connected to the feeding source of the meal. This duct (5) discharges the meal onto the top of a conical downwardly diverging tray (1) arranged in the container (4), and arranged at a suitable distance below said tray (1) is another conical member (6) also diverging downwardly and provided with an upwardly directed peripheral edge (106) extending beyond the peripheral outline of the tray, and closely spaced from the side surface of the cylindrical container. At the top of the conical member (6) is an opening (10) which is connected to a conduit (11) extending through the wall of the container (4) and connected to a suction source. Inside the container (4) below the conical members (1, 6), there opens a conduit (15) communicating with the atmosphere.

Abstract: Separator device for edible meal, comprising a vertical cylindrical container (4) provided at its the bottom with a discharge rotary valve (9). A feeding duct (5) extends axially into the top portion of the container, and swirling means are provided so that the meal to be treated will reach with a whirling flow the central portion of a distributing chamber (31) having equispaced lateral openings (32) from which equal spiral-shaped tubes (33) protrude outwards with the same curvature, whereby the meal is discharged tangentially onto the periphery of an underlying horizontal dish (6) which is arranged co-axially in the upper portion of the container (4). Arranged at a suitable distance above the disc there is a horizontal partition (1) which is fixed to the container and is sealingly traversed by the curved feeding tubes (33).
