A method and an apparatus (1) for the production of a compound used for the manufacture of an article made from rubber or a pneumatic tyre by means of a continuous mixer (2) divided into a mixing section (MS) wherein the mixing of the components of the compound being processed exclusively takes place; a reaction section (RS) located downstream of the mixing section (MS) wherein a mild reaction of the compound being processed is activated; wherein, the reaction section (RS) is provided with heating means for increasing the temperature of the compound being processed in relation to the temperature of the compound being processed within the mixing section (MS); and a cooling section (CS) located downstream of the reaction section (RS) and provided with means for the cooling of the compound being processed down to a temperature that will inhibit further development of the reaction that takes place within the reaction section (RS).

In the field of mixing rubber mixtures, o a rotor (100), for use in an internal mixer having a mixing vessel in which the rotor rotates includes one or more blades (104), each blade having a tip (104a) with a profile having a predefined curvature and an anti-wear device detachably fixed to the tip (104a) of at least one blade. The anti-wear device includes a plate (110) with a profile defined by a lower surface (112) with a curvature complementary to that of the tip (104a) and an upper surface (114) with a curvature complementary to that of a wall of the vessel to define, between them, a zone of minimum distance that allows a passage of the mixture between the plate (110) and the wall of the vessel. One or more fastening systems (135) are fitted and tightened with respect to the plate (110) so as to engage the rotor (100).

Provided is an automatic continuous weighing/raw material supply system of a flooring tile manufacturing apparatus, and more particularly to an automatic continuous weighing/raw material supply system of a flooring tile manufacturing apparatus, which can stably supply a raw material to the flooring tile manufacturing apparatus.

An environment-friendly material includes 50 wt % to 70 wt % of inorganic mineral powder, 20 wt % to 45 wt % of polyolefin, and 5 wt % to 15 wt % of auxiliary agent. The inorganic mineral powder contains calcium carbonate; the polyolefin may be linear low density polyethylene, low density polyethylene, medium density polyethylene, high density polyethylene, or polypropylene; and the auxiliary agent may be polyolefin elastomer, maleic anhydride grafted polyolefin elastomer, or maleic anhydride grafted polyethylene. The disclosure also provides a manufacturing method of window covering slat using the environment-friendly material and a window covering slat manufactured by the method.

An extruder includes a mixing device having a mixing chamber formed by a housing, a stator and a rotor. The stator and the rotor are arranged at least partially within the mixing chamber. The stator is connected to the housing and/or is formed by the housing. The rotor is rotatable about an axis of rotation (D). At least one free space, into which the stator projects at least partially in the direction of the axis of rotation (D), is formed by the rotor. The stator and/or the rotor have/has at least one temperature control channel, through which a temperature control fluid can be made to flow in order to control the temperature of the stator and/or of the rotor. The extruder further includes a screw housing, a screw drive, and an extruder screw, which is mounted to the screw housing and is coupled to the screw drive.

A method and an apparatus (1) for the production of a compound used for the manufacture of an article made from rubber or a pneumatic tire by a continuous mixer (2) divided into a mixing section (MS) wherein the mixing of the components of the compound being processed exclusively takes place; a reaction section (RS) located downstream of the mixing section (MS) wherein a mild reaction of the compound being processed is activated; wherein, the reaction section (RS) is heated to increase the temperature of the compound being processed in relation to the temperature of the compound being processed within the mixing section (MS); and a cooling section (CS) located downstream of the reaction section (RS) and cooled to reduce the temperature of the compound being processed down to a temperature that will inhibit further development of the reaction that takes place within the reaction section (RS).
