The invention relates to a heatable mixer (1) for composite products based on thermoplastic material(s), having an elongated structure defining a longitudinal processing path between an inlet and an outlet and comprising a heated trough (3) wherein two mutually interpenetrating parallel twin screws (4 and 4) are mounted, forming member(s) for dimensionally reducing, heating and moving the products to be treated which are inserted at the inlet, each screw (4, 4′) comprising a heated and driven support shaft (5) arranged in the travelling direction (DT). Mixer (1) characterised in that the thread (4″) of each screw (4, 4) is an interrupted or discontinuous thread and comprises, over at least a major portion of the length of the relevant screw (4, 4′), a plurality of first blades (6) in the form of flat and smooth plates which are separated from each other axially and radially and all arranged according to a constant.

A system and method for recycling used asphalt material through convection heating and gentle tumbling recycles used asphalt material, such as reclaimed asphalt pavement, by uniformly and gradually applying radiant and convectional heating towards the used asphalt material. A radiant heating coil generates a controlled amount of radiant heat, at about 325 degrees, and up to 750 degrees Fahrenheit. At least one blower works to blow the radiant heat to the used asphalt material as convectional heat. An agitating conveyor simultaneously carries the used asphalt material while it is being heated. The agitating conveyor has a radiant heated conveyor floor that comprises depressions that work to agitate the used asphalt material. The uniform heating of the used asphalt material inhibits moisture from surging from the used asphalt material and maintains integrity of the subsequently formed rejuvenated asphalt. A rejuvenating chamber mixes the used asphalt material with a rejuvenating composition.

The extruder (20) includes a pair of hollow core extrusion screws (50, 52, 124, 126, 190) having elongated hollow core shafts (54, 128, 130, 192) equipped with helical fighting (56, 132, 134, 194) along the lengths thereof. The fighting (132, 134, 194) is also of hollow construction which communicates with the hollow core shafts (54, 128, 130, 192). The flighting (56, 132, 134, 194) also includes forward, reverse pitch sections (64, 162, 216). The extrusion screws (50, 52, 124, 126, 190) are designed to impart high levels of thermal energy into materials being processed in the extruders (20), without adding additional moisture.

The invention relates to a process for hot application of an adhesive composition (80) on a support (96), by means of a system comprising: a nozzle (50) for applying the adhesive composition (80), a line (88) for supplying the nozzle (50) with the adhesive composition (80) to be applied in fluid form, a mixer (30) positioned in the line (88) for the homogeneous mixture of the main components of the adhesive composition before its application; the applied adhesive composition (80) including as main components: a silylated prepolymer, a compatible tackifying resin; the adhesive composition comprising a cross-linking catalyst; the process comprising: supplying the line (88) with the silylated prepolymer separated from the cross-linking catalyst, the mixing of the cross-linking catalyst with the main components by means of the mixer (30), the hot application of the mixed adhesive composition (80) onto a support (96).

A stirrer (1; 100) for stabilizing liquid binding unfinished products intended to form ceramic items comprising a support shaft (2) individuating a longitudinal rotation axis (Y) and contained into a mixing tank (V) of the liquid binding unfinished product, motorization means (3) operatively connected with the support shaft (2) in order to rotate it around the longitudinal axis (Y), and a main operating blade (4), coupled with the support shaft (2) through interconnection means (5) in such a way as to be contained into the mixing tank (V) in order to interfere with the liquid binding unfinished product and cause its continuous mechanical mixing action inside the mixing tank (V) itself when the support shaft (2) rotates around the longitudinal axis (Y). In this case, the stirrer (1) includes a thermoregulation circuit (6), which extends within the support shaft (2) and within the main operating blade (4) and is connected with an external source for supplying a heat transfer fluid crossing the thermoregulation circuit (6) in such a way as to exchange heat with the liquid binding unfinished product within the mixing tank (V), in order to bring the it to a predefined temperature, while the support shaft (2) and the main operating blade (4) integral with it rotate around the longitudinal axis (Y).

The invention relates to a rotary shaft for processing foodstuffs, the rotary shaft has a rotation axis and the rotary shaft comprises at least one tool which extends along the rotation axis. The tool has an airfoil profile such that the tool comprises a leading edge, a trailing edge, an upper surface and a lower surface. Further, the tool comprises at least one fluid channel between the mean camber line of the airfoil profile and the upper surface of the tool.
