The invention relates to an apparatus, system, and method for the bulk blending of dry component materials to produce a blended product mix. The apparatus utilizes a special construction that allows multiple bulk dry materials to be added simultaneously to create a blended mix compliant with a desired or specified mixture of cement components. The system is automated by use of a controller, and provides real-time data to a user as to rates and amounts of materials blended and delivered over time.

The present invention relates to an equipment and method for producing polymer pellets which comprise one or more polymer components and one or more further components, wherein in said process at least one of said one or more further components is incorporated into pellets by applying a liquid, which comprises said at least one component, onto said pellets.

A processing vessel (1) provided with a material inlet (2, 3, 4, 5) and a processed material outlet (25) wherein the material flows continuously through the vessel which is split into a series of zones (6, 7, 8) through which the material passes wherein the zones are shielded from each other by controlling the rate at which the material flows and an increasing level of vacuum is applied inconsecutive zones and the system is provided with acoustic energy which imparts energy to the process material by virtue of the contact between the zone dividers and the process material and processing material in such a vessel.

A sink is configured to attach to a bottom surface of a flowline that is configured to flow a mixture of at least two immiscible fluids. One of the immiscible fluids is water. The water is more dense than the other of the at least two immiscible fluids. An outlet formed at a bottom portion of the sink. A valve system is connected to the opening. The valve system is configured to open the outlet in response to the water occupying at least a portion of the sink.

A technique facilitates mixing of cement slurry for use in a cementing application. At least one cement mixer is provided with a tank, e.g. a conical tank, having a powder cement blend inlet and a mixing liquid inlet. A cement slurry discharge may be positioned generally beneath the tank. A mixing assembly also is positioned below the tank and driven by a shaft. The mixing assembly is exposed to an interior of the tank and is used to mix the cement slurry when rotated by the shaft and to direct the cement slurry out through the cement slurry discharge. Additionally, a recirculation system comprises an inlet positioned to receive a portion of the cement slurry mixed in the mixing assembly. The recirculation system also comprises an outlet positioned to direct the portion back into the mixer to enhance mixing effects.

A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. The blender has a plurality of material handling compartments. One or more cleaning air jets are provided in each material handling compartment. The cleaning air jets are operable to direct material towards an outlet of the compartment. Each cleaning air jet is connected to a pressurised air supply through a valve which controls delivery of pressurised air to the cleaning air jet.

The present invention provides a microfluidic mixing platform having a bulk, the platform including an inlet well, a microchannel, a passive capillary valve a mixing feature and an outlet. The passive capillary valve prevents unwanted capillary flow along the microchannel. The passive capillary valve comprises a widening of the microchannel relative to the direction of fluid flow, and the angle has a graduated profile. The mixing platform bulk comprises a rigid matrix capable of machine manufacture. A method of preventing backflow in a microfluidic mixer is also provided.

Provided is a production method with which a large amount of particle mixture in which two or more types of particles are mixed can be easily produced. The production method is for producing a particle mixture in which two or more types of particles are mixed, and includes the following steps (1) and (2): (1) a step of adding a first additive to first particles and mixing the first additive with the first particles using a first mixer; and (2) 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.

According to one embodiment a solid component mixing apparatus is provided that includes a mixing device, a first dosing device for supplying sand and a second dosing device for supplying a solid additive that are communicated with the mixing device. The mixing device includes a vertical mixing chamber with a rectangular cross-section, the contour of the chamber being formed by four side walls, such that two side walls opposite one another are wider than the other two walls. The chamber includes a first inlet communicated with the first dosing device and a second inlet communicated with the second dosing device, the second inlet being at a lower height than the first inlet, and the second inlet being arranged in one of the wider side walls of the chamber. Associated mixing methods are also provided.
