A stirring and defoaming device is a stirring and defoaming device of a revolution and rotation type, wherein a vacuum unit for sucking air in each container to bring the inside of each container into a vacuum state includes sealing bodies that seal respective containers, a vacuum generation source, a suction path running toward a revolution center with each container as a starting end, passing through the revolution center to go outside the system, and reaching the vacuum generation source placed outside the system, at least part of the suction path being an independent path from the starting end in association with each container, and at least two or more vacuum measurement units, each provided in an independent path.

A asphalt pavement recycling device comprising a base frame hingedly secured to a platform, a rotatable drum unit rotatably secured to the base frame, the drum unit having a drum opening and a drum rear, a hopper assembly hingedly secured to the base frame, a burner assembly hingedly secured to the base frame wherein the burner is used to heat the materials which are to be recycled/processed, a fuel source, a plurality of right-handed flights secured within the rotatable drum unit, a plurality of left-handed flights secured within the rotatable drum unit, a plurality of gator plates secured within the rotatable drum unit, a hydraulic unit secured to the device and operationally associated with the base frame, the rotatable drum unit, the hopper assembly and the burner and a control station operationally associated with the hydraulic unit, the base frame, the rotatable drum unit, the hopper assembly and the burner.

Devices, systems, and methods are provided for mixing a compact dual axis centrifugal mixer configured to rotate a receptacle containing a voluminous substance to be mixed about two different axes. The compact dual axis centrifugal mixer may be configured to function as a tabletop mixer. The dual axis centrifugal mixing device of the invention may further include power transmission system adapted to transmit rotational energy produced by a rotary motor to a second rotatable housing allowing synchronous or asynchronous rotation of the second rotatable housing in relation to a first rotatable housing.

A magnetic spinner device using an impeller system to disperse heat and stir contents there-above is disclosed herein. A motor turning the impeller is offset from a center line extending vertically through the device. The impeller, however, is centered with fan blades pushing air downwards as heat rises from a heat source placed there-below, such as between legs which support the impeller and bowl of the device, the bowl being used to hold a flask and/or substances to be heated. The turning of the motor is translated to the turning of the impeller by way of two reels connected by a belt and placed within a lower housing with a removably connected lower portion. In this manner, the electric parts (the motor) and spared the brunt of the heat by being off-center while the heat rises upwards. The simplification of parts leaves less points of potential failure compared to the prior art as does the movement of electric parts away from being above a heat source.

Process for the preparation of layered particles are provided. Layered particles prepared by such processes are also provided

Apparatus uses engineered collection media to recover mineral particles in a slurry. The apparatus has a tumbler cell and a rotation device to rotate the tumbler cell. The tumbler cell has a container to hold a mixture of the engineered media and the slurry containing the mineral particles. The container is turned such that at least part of the mixture in the upper part of the container is caused to interact with at least part of the mixture in the lower part of the container. As such, the contact between the engineered media and the mineral particles is enhanced. The surfaces of the engineered media are functionalized with a chemical having molecules to attract the mineral particles to the surfaces so as to form mineral laden media. After the mineral laden media are discharged from the tumbler cell, the mineral particles can be separated from the engineered media by stripping.

A mixing drum includes a body defining a discharge aperture, a head coupled to the body opposite the discharge aperture, and a mixing element. The body includes an inner layer defining an interior surface of the body and an outer layer defining an exterior surface of the body. The head includes a connecting flange extending between the inner layer and the outer layer of the body. The head and the body define a volume. The mixing element is positioned within the volume and coupled to the body.

Disclosed cyclonic flow-inducing pumps overcome drawbacks associated with known adverse flow conditions that arise from flow of certain types of materials through a material flow conduit. Such cyclonic flow-inducing pumps provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile such as, for example, increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated adverse considerations such as slugging.

A biological production system includes a mixing vessel and an agitation device. The mixing vessel includes an outer housing, an internal mixing structure, and a reaction chamber. The mixing vessel is configured to provide low shear agitation to materials in the reaction chamber in response to force from the agitation device.
