A method of making a homogeneous mixture of polyolefin solids and liquid additive without melting the polyolefin solids during the making The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the liquid additive for a period of time sufficient to substantially intermix the polyolefin solids and the liquid additive together and while maintaining temperature of the heterogeneous mixture above the freezing point of the at least one liquid additive and below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.

A method of making a homogeneous mixture of polyolefin solids and a particulate solid additive without melting the polyolefin solids or the particulate solid additive during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the particulate solid additive for a period of time sufficient to substantially intermix the polyolefin solids and the particulate solid additive together and while maintaining temperature of the heterogeneous mixture below the melting point of the at least one particulate solid additive and below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids or the at least one particulate solid additive.

A powder provisioning device is for a powder doser, in particular for a tamping pin station. The powder provisioning device comprises a powder container, which can be driven in rotation, for receiving a powder bed, and a stationarily mounted smoothing device for the powder bed. The stationarily mounted smoothing device includes a stirring unit having at least one stirrer which projects into the interior of the powder container and can be driven in rotation.

A production method for producing a particle mixture in which two or more types of particles are mixed, including a step of adding a first additive to first particles and mixing the first additive with the first particles using a first mixer and a step of introducing the two or more types of particles including the first particles mixed with the first additive and second particles into a blender container of a gravity blender, and mixing the two or more types of particles inside the blender container.

A method of forming a composite material includes mixing granules of thermoplastic(s) and granules of reinforcing material(s) using a mixer with an interior friction coating. The friction generated by interaction between the granules and friction coating causes granules of at least one of the thermoplastic(s) to be heated to a liquid or semi-liquid state. The liquid/semi-liquid thermoplastic(s) act a binder for the mixed material. A system for forming such a composite material includes such a mixer with an interior friction coating. The system may also include a mould and/or a press for forming material produced by the mixer into a finished shape. The method and system may use post-consumer and post-industrial material as an input allowing such material to be recycled. In some cases, cross-contaminated or mixed post-consumer/post-industrial material may be recycled, potentially reducing environmental impacts.

A mixing apparatus for mixing fluids, in particular inks of different colours for fountain pens, the mixing apparatus comprising containers (12a-12d), each adapted for storing a fluid, a tube element (13a-13e), for each container (12a-12d), connected to the container (12a-12d) and having a dispensing end portion at its end being opposite the container (12a-12d), a fluid feed device adapted for dispensing fluid from the containers (12a-12d) via the dispensing end portions, and a mixing space part encasing element (45) having a mixing space part in its inner space, the dispensing end portions of the tube elements (13a-13e) are arranged to extend into the mixing space part, and a filling unit (10) having a base portion (44) and a neck portion (40) adapted for holding the mixing space part encasing element (45), and the base portion (44) and the neck portion (40) are configured to be movable relative to each other, and are adapted for encompassing a container (25) being connectible to the fluid discharge portion. The invention is furthermore a mixing system for mixing fluids comprising a data entry unit (200), a control unit, and the mixing apparatus. The invention is furthermore a fountain pen (100) comprising a container (25) adapted for storing ink which is filled up applying the mixing apparatus.

A centrifugal mixing device can include a shaft assembly that is operably coupled to a motor such that the motor rotates the shaft assembly about a first axis. The devices can further include a turret that is rotatably coupled to the shaft assembly such that the turret rotates about the first axis relative to the shaft assembly. The turret can include a first support, a first canister rotatably coupled to the first support such that the first canister rotates about a second axis, and a second canister rotatably coupled to the first support such that the second canister rotates about a third axis. The turret is configured to rotate about the first axis in a first rotational direction and each of the first and second canisters is configured to rotate about the second and third axes, respectively, in a second rotational direction that is opposite the first rotational direction.

An additive feeder assembly includes a supply reservoir having an outlet and an outlet tube having a first end in fluid communication with the outlet and a second end located vertically higher than the supply reservoir. An air stream transports a first granular material discharged from the supply reservoir and into the first end of the outlet tube to the second end of the outlet tube. A granular material distributor is in fluid communication with the second end of the outlet tube. The granular material distributor has a top end configured for attachment to a feed supply for a second granular material, a central portion located vertically below the top end and configured to mix the first granular material and the second granular material, and a bottom end configured for vertically discharging the mixed first granular material and second granular material.

A method for manufacturing a pelletised mineral product, the method comprising: in a first mixing step, forming a first mixture by mixing the evaporite mineral with non-gelatinised starch under conditions that are insufficient to substantially gelatinise the starch; in a second mixing step, forming a second mixture by mixing the first mixture under conditions that are sufficient to substantially gelatinise the starch comprised within the first mixture; and forming the second mixture into pellets.
