A temperature sensor (10) for measuring a temperature of a mixture being mixed in an internal mixer includes a fixed part having a substantially cylindrical body (12) and a removable part (16) of domed shape arranged inside a conduit of the body. The temperature sensor also includes a blowing stem (14) in communication with a source of compressed air that extends along a conduit (12c) of the body and terminates at an outlet end (14a) disposed in the removable portion (16), whereby the compressed air exits the blowing stem (14) and passes uninterruptedly through a temperature measuring element or elements at a contact end (16b) of the removable portion. A combination of an internal mixer and a temperature sensor for measuring a temperature of a mixture being mixed in the internal mixer is also disclosed.

A method of forming a polyethylene terephthalate (PET) mixture with talc includes: providing a feed of PET (PET feed); providing a feed of talc (talc feed); mixing the feed of PET with the feed of talc in a mixer at a PET:talc ratio of about 3:1 to about 1:3 to form a PET/talc mixture; and providing the PET/talc mixture as output. A method of forming a Polyethylene Terephthalate (PET) alloy having talc includes: providing a feed of the PET/talc mixture (PET/talc feed); providing a feed of PET (PET feed); mixing the feed of PET with the feed of PET/talc in a mixer to form a PET alloy having from about 1% (w/w) talc to about 50% talc (w/w); and providing the PET alloy as output.

A rubber composition manufacturing method comprises an operation in which at least rubber, silica, and silane coupling agent are kneaded in an internal kneader at not less than a temperature lower limit for a coupling reaction between the silica and the silane coupling agent to proceed. For at least a portion of time during which that operation is being carried out, a compressed gas is delivered to the kneading chamber while the ram is in a nonpressing state.

A rubber composition manufacturing method comprises: an operation in which at least amine antioxidant, zinc oxide, silane coupling agent, silica, and rubber comprising modified polymer are fed into an internal kneader; and an operation in which kneading is carried out at the internal kneader while kneading temperature is controlled so as to suppress occurrence of a coupling reaction between the silica and the silane coupling agent, and so as to suppress occurrence of a bonding reaction between the silica and the modified polymer.

A method for processing pharmaceutical powders, which comprises providing a feeder module including a plurality of feeder units each with a storage hopper, a weighing cell, a conveyer, and a discharge end, connecting the storage hopper to a refilling system with a refilling valve, connecting the refilling valve to a level or weight indicator disposed above the refilling valve, connecting the discharge end to a common receiving container, refilling the storage hopper with a powder intermittently 40 to 80 times per hour, storing data during refilling, transporting powder from the storage hopper with the respective conveyer, and discharging powder from each feeder unit into the common receiving container. During each refilling of the storage hopper, the refilling valve dispenses powder into the storage hopper and, during the step of transporting the powder from the storage hopper, the conveyer is operated according to the data collected during previous refills.

A method for producing a rubber composition containing a rubber wet master batch has a masticating process. The masticating process comprises step 1 of charging the rubber wet master batch into an enclosed kneading chamber that has a stirring rotor showing a rotation speed controllable automatically through a control unit and that is capable of detecting and outputting an internal temperature, step 2 of setting a first control time and a first target temperature in the control unit, and step 3 of stirring the inside of the kneading chamber while making a PID control for adjusting an actually measured temperature in the kneading chamber to the first target temperature through the control unit on the basis of information on the actually measured temperature and the first target temperature, thereby automatically controlling the rotation speed, until the first control time elapses after the completion of the two steps.

A kneader internal inspection device according to the present invention suspends and supports a photographing unit, which is arranged in an interior of a kneader and which photographs the interior, so as to be vertically movable in the interior of the kneader. Therefore, such a kneader internal inspection device is capable of easily inspecting the interior of the kneader.

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.
