A roasting drum has a main body and at least one opening formed through the main body. The main body has a first end, a second end opposite the first end, and multiple drums. The multiple drums are mounted around one another in sequence, are fastened to one another, and communicate with one another. Each one of the multiple drums has a blending blade formed on an inner surface of the drum. The blending blade is spiral and extends from the first end toward the second end. The blending blade of one of the multiple drums twists along a clockwise direction from the first end toward the second end. The blending blade of another one of the multiple drums that is mounted around the drum twists along a counter-clockwise direction from the first end toward the second end.

Mobile mixing attachments, skidsteers with mobile mixing attachments, mobile mixing devices and related methods are provided. A mobile mixing attachment for use on a skid-steer can include a rotatable mixing drum having a body that forms an internal cavity and having a forward end and a bottom end. The mixing drum can include a mouth at the forward end of the body that provides access to the internal cavity of the mixing drum. The mobile mixing attachment can include a drum chassis configured to hold and rotate the mixing drum and an attachment plate secured to a rear portion of the drum chassis proximal to the bottom end of the body. The attachment plate configured to engage one or more attachment couplers on lift arms of a skid-steer. The mobile mixing device also comprises a scoop comprising a forward scooping lip and a rear loading end positioned in front of the mouth of the mixing drum. The scoop is secured to the drum chassis.

A portable mixing apparatus for mixing components is disclosed. The apparatus comprises a container for receiving components to be mixed, a frame for supporting the container in a first orientation for mixing components and a driving assembly couplable with the container for rotating the container. The frame comprises: a first handle for gripping with a first hand of a user, the first handle being disposed above a centre of mass of the portable mixing apparatus, when orientated in the first orientation, the first handle extending forwardly of the apparatus over the container; a second handle for gripping with a second hand of the user while the first hand grips the first handle, the second handle being disposed below the centre of mass of the portable mixing apparatus when orientated in the first orientation, the first and second handle being arranged to enable the user to carry the mixing apparatus and re-orientate the apparatus between the first orientation and a second orientation for emptying the components from the container.

A resin dispensing apparatus includes a supply unit including a syringe having an internal space configured to hold a phosphor-containing resin. An agitator is disposed in the internal space. The supply unit is configured to rotate at least one of the syringe and the agitator to prevent settling of phosphor contained in the phosphor-containing resin. A discharge unit includes a cylinder having a discharge nozzle through which the phosphor-containing resin, received through a connecting pipe connected to the syringe, is discharged. A piston provides pressure to discharge the phosphor-containing resin through the discharge nozzle inside the cylinder.

A device for wetting particles, in particular wood particles, with an application agent, at least one conduit transporting a fluid as a fluid stream and an end section which forms an outlet. The fluid can be introduced in the direction of the main flow into a container containing the particles, via the outlet. The particles are in the container in a loosened state and/or can be loosened. The application agent, for spraying by a nozzle device with a speed component directed against the main flow direction, can be introduced into the fluid stream and can be guided to the particles by the fluid stream.

An apparatus for producing hot mix asphalt from 100% recycled pavement aggregates includes a rotatable inclined drum having a central axis and having a first and second end. A heat source spaced from one of the ends introduces hot gas into the drum via one of the first and second ends. An aggregate supply introduces aggregate into the drum through one of the first and second ends. A RAP collar spaced from the ends and positioned around the drum is used to introduce sand through openings beneath the collar into the drum as the drum is rotated. The RAP collar has an annular heat and smoke shield fastened around the drum for minimizing escape of hot gas from the drum openings beneath the RAP collar. The drum has replaceable buckets within the openings for receiving, holding and distributing sand into the drum as the drum rotates about its axis.

A gyroscopic rotational monitoring system may be utilized for monitoring one or more properties of rotatable container or vessel, and/or one or more properties of a displaceable material contained in the rotatable vessels. An exemplary aspect relates to the use of a gyroscope and periodicity sensor (e.g., accelerometer) to determine rotational speed of a concrete mixing drum, so that the slump or other property of the concrete can be monitored or adjusted such as by dosing with water, chemical admixtures, or mixture thereof.

In a reaction apparatus, a kiln part includes a supply port configured to receive a raw material supplied to one end side thereof, a discharge port configured to discharge a reaction product to another end side thereof, a cylindrical par extending along and rotatable around a central axis thereof, and a baffle plate provided so as to extend from an inner wall of the cylindrical part and pass through a central area of the cylindrical part including the central axis thereof. A driving part rotates the kiln part around the central axis. A heating part heats an outer peripheral part of the kiln part. The kiln part is configured so that a received predetermined raw material is conveyed to the discharge port along the central axis while being in contact with the baffle plate.
