A double shaft paddle mixer, including a barrel chamber, and a first paddle screw and a second paddle screw. The first paddle screw is provided with first paddles and the second paddle screw is provided with second paddles. The barrel chamber includes a crushing zone and a mixing zone. The crushing zone is partly separated from the mixing zone by a partition member. A first inlet is connected to the crushing zone and a second inlet is connected to the mixing zone and an outlet connected to the mixing zone. The double shaft paddle mixer can be part of an arrangement and part of a method for producing paste.

Provision of a manufacturing apparatus that can perform steps including a kneading step to a granulating step in one apparatus, can achieve a reduced size of the apparatus as a whole, and can reduce the variation in the diameter of kneaded granules. A manufacturing apparatus comprises: a kneading section feeding a kneaded material to a downstream side in the carrying direction while kneading a raw material; a granulating section performing granulation from the kneaded material generated in the kneading section.

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.

An at least two shaft reactor/mixer, in particular for process engineering treatment of highly viscose, elastic and/or solid containing reaction substance and mixture, in which at the housing inner wall inwardly directed static mixing elements are arranged, which interact with scrapers of the at least two shafts in such a way, that in the area of the spaces between the scrapers the static mixing elements and the housing inner wall sheer forces, in particular a flow disturbance, are generated in an enhanced manner. In addition, there is a system including an end cap for a one or multiple shaft reactor/mixer and a discharge screw connector block being connectable with the end cap in a detachable manner.

A horizontal fluent material dispenser for the even dispensing of a metered quantity of powder. A hopper holds the powder. The hopper has a mixing portion with rotating beaters. A horizontal conduit is coupled to the hopper and receives powder from the hopper. A screw conveyor—or auger—within the conduit transfers the material through the horizontal conduit. A knife assembly, disposed at the distal longitudinal end of the screw conveyor, breaks off a continuous and even flow of powdered material out the discharge opening. A modular screw conveyor assembly is disclosed for changing the material dispensing rate range without changing the conduit diameter. A dual drive mechanism is also disclosed for independent adjustment of the rotating beater speed and the screw conveyor.

Continuous method including mixing water and cementitous powder to form slurry; mixing the slurry and reinforcement fibers in a single pass horizontal continuous mixer to form fiber-slurry mixture, the mixer including an elongated mixing chamber having a reinforcement fiber inlet port, and upstream of the fiber inlet port is an inlet port to introduce water and cementitous powder together as one stream or at least two inlet ports to introduce water and dry cementitous powder separately as separate streams into the chamber, a rotating horizontal shaft/s within the chamber, part of the chamber for mixing the fibers and slurry and moving the fiber-slurry mixture to a mixture outlet; discharging the fiber-slurry mixture from the mixer outlet; forming and setting the fiber-slurry mixture on a moving surface; cutting the set mixture into fiber reinforced concrete panels and removing the panels from the moving surface.

The present invention is directed to a continuous process for producing a foamable celluloid product by introducing a solid component (comprising nitrocellulose, chemical blowing agent (CBA), stabilizer and alcohol) and a liquid component (comprising camphor and acetone) into a mixer/devolatilizer machine where the chamber is under atmospheric pressure and having significant overhead space. The chamber is comprised of two zones wherein the first zone has a temperature that is less than the second zone and at least one rotor comprising hollow, temperature-controlled arms having a tilted angle affixed to the rotors. The rotors of the mixer/devolatilizer machine act to mix the solid and liquid components under lower shearing forces, lower mechanical stress and longer residence times than those used by twin-screw extruders.
