Therefore, such a kneader internal inspection device is capable of easily inspecting the interior of the kneader.

A material wetting system for wetting a powder material includes a liquid supply system, a material mixing unit, a material supply system, and a shroud assembly. The liquid supply system includes a supply line. The material mixing unit is in fluid communication with the supply line and includes a central cavity having an open upper end configured to receive a supply of powder material. The material mixing unit is configured to receive liquid from the supply line and is operatively connected to a reduced pressure source to draw air into the central cavity. The material supply system includes an orifice and is configured to feed powder material through the orifice, with the orifice disposed above the central cavity of the material mixing unit. The shroud assembly is disposed about the open upper end of the central cavity of the material mixing unit and the orifice of the material supply system.

A kneading apparatus for a thermoplastic resin, includes: a plasticizing cylinder which has a high pressure kneading zone and a pressure reduction zone; a screw in the plasticizing cylinder; a downstream side seal mechanism which shuts off communication between the high pressure kneading zone and the pressure reduction zone; and a pressure reduction zone pressure adjusting mechanism which is connected to the pressure reduction zone and which controls a pressure of the pressure reduction zone so that the pressure is not less than an atmospheric pressure and the pressure is not more than a maximum pressure of the high pressure kneading zone that is achieved when kneading a molten resin with a pressurized fluid, when the downstream side seal mechanism shuts off the communication between the high pressure kneading zone and the pressure reduction zone.

A device for loading an in particular higher-viscosity liquid, such as a silicon resin, for example, with air or another gas. The device has a pressure vessel receiving the liquid and the gas, in which pressure vessel an agitator, having a drive shaft set through the pressure vessel at least in part, is arranged. In order to enable the particularly fast and homogeneous intermixing of the liquid and gas, the drive shaft is arranged in a conveying pipe and drives a conveying organ, in particular a screw conveyor, which transports the liquid through the conveying pipe to at least one outlet, and there is an running-off surface underneath the outlet from the conveying pipe for the liquid flowing out of the outlet. Upon actuation of the agitator, the liquid is thus not only well intermixed together with the air already received therein, but at the same time conveyed through the conveying pipe to the running-off surface, on which it can discharge in a thin layer and has a particularly large exchange area with the gas as a result.

Embodiments of the present disclosure involve methods, devices, and systems for hydrating polymers using multiple mixing chambers. Adjacent mixing chambers may be coupled using an under-over baffle, and each mixing chamber may be generally rectangular with rounded corners.

An extruder screw for plasticizing at least one plastic or plastic mixture, including a melting zone, a shaft zone and a mixing zone arranged between the melting zone and the shaft zone, wherein a conveying flight is formed in the melting zone and in the shaft zone, which extends helically along a longitudinal axis of the screw, wherein a conveying flight of the melting zone ends at an end of the melting zone towards the mixing zone and a conveying flight of the shaft zone begins at an end towards the mixing zone. A flight depth of the melting zone continuously decreases along the longitudinal axis of the screw to the mixing zone. Further, an extrusion device having the extruder screw and to a method for plasticizing at least one plastic or plastic mixture.

The present disclosure discloses a meshing-type rubber internal mixer and a working method thereof. The meshing rubber internal mixer includes a frame mechanism, a mixing mechanism, and an unloading mechanism. The mixing mechanism is on the upper side of the unloading mechanism. The mixing mechanism and the unloading mechanism are in the frame mechanism. An internal mixing chamber is of a closed structure through first automatic telescopic plates and second automatic telescopic plates. The gap between a first meshing-type rotor and a second meshing-type rotor is small, a material is compressed to enter the space between the first meshing-type rotor and the second meshing-type rotor to be extruded with an internal mixing chamber wall. The material is flaky in the internal mixing chamber, so that the material produces great strain deformation, thereby achieving excellent dispersing and mixing effects.

A submersible substance separator system having an outer chamber, a top cover plate, an upper cup, a disc stack separator; a middle cup, a submersible actuator, a lower cup, and an interior chamber within the outer chamber; in which one section of the disc stack separator is configured to lead, in response to centrifugal forces, a first separated substance into the upper cup and subsequently into the outer chamber until it reaches a chamber outlet corresponding to the outer chamber; and wherein another section of the disc stack separator is configured to release, in response to centrifugal forces, a second separated substance into the interior chamber until it reaches a chamber outlet corresponding to the interior chamber.

A reactor assembly is provided for heating plastic material. The reactor assembly includes: a reactor vessel including a central axis; and an agitator mounted within the reactor vessel. The agitator includes: one or more blade(s) distal from the central axis for mixing contents of the reactor vessel in use; and one or more wearing parts mounted to the blade(s) to extend from the blade(s).

A feeding screw machine serves for feeding a processing screw machine. The feeding screw machine comprises a housing with at least one housing bore formed therein. An associated screw conveyor shaft is rotatably disposed in the at least one housing bore to convey material in a conveying direction from a supply opening to a feeding opening. An emptying opening is formed in the housing. The emptying opening enables an easy, fast and reliable emptying and cleaning of the feeding screw machine independently of the processing screw machine.
