Abstract: A system and a process is provided for reducing the dust formation during the transfer of a particulate material on an endless conveyor belt. During transfer of the material on the conveyor belt the material is first sprayed with a wetting agent then by application of a plow the moving material is lifted from the bottom of the belt and is diverted towards the side edges of the belt thus creating additional exposed surfaces. The material is then again sprayed then contacted with baffles to redirect the material from the side edges towards the center of the belt thus creating additional exposed surfaces which are then again sprayed with a wetting agent to substantially eliminate dusting. The plow and baffle combination can also be used for uniformly mixing two or more particulate materials on a moving belt.

Abstract: A drum-type drier and/or mixer in which particulate material such as aggregate or recycled asphalt is introduced into the forward end of the drum. A burner at the rear end of the drum directs its flame forwardly through an elongated firing tube which extends from the rear end of the drum toward the forward end thereof. The hot gases discharged from the tube strike a baffle, are deflected into an annular chamber between the tube and the drum and then flow rearwardly through the chamber to an exhaust stack. The particulate material also is advanced rearwardly through the chamber and, during such advance, is heated (1) indirectly by the hot gases flowing forwardly through the firing tube and (2) directly by the hot gases deflected into and flowing rearwardly through the chamber.

Abstract: A closed loop system which includes (1) a drum mixer, (2) a heat source separate from the drum mixer for producing a heated gas, (3) intake and exhaust ducts which channel, respectively, the gas produced by the heat source to the intake end of the drum mixer, and the gas at the discharge end of the drum mixer back to one intake of the heat source, and (4) a fan for maintaining the flow of gas in the system. The gas produced by the heat source is between 700.degree. F. and 2000.degree. F. when it enters the drum mixer at its intake end from the intake duct. Graded aggregates and a bituminous binder are fed into the drum mixer at its intake end. The graded aggregates are mixed with the bituminous binder, in the presence of the heated gas, by rotational action of the drum mixer. The resulting bituminous paving mixture is discharged at the discharge end of the drum mixer, along with exhaust gas, a portion of which is channeled back to one intake of the heat source by the exhaust duct.

Abstract: An asphalt regenerating apparatus including a drum in which blade means is provided and hot water is contained is disclosed. The asphalt waste is introduced into the drum and heated by the hot water contained in the drum. By revolving the blade means, the heated asphalt waste is subdivided, thereby becoming aggregate particles each having the surface coated with a thin asphalt film.

Abstract: Recycled asphalt-aggregate compositions prepared by adding a suitable amount of make-up asphalt to pieces of the used composition and heating the mixture in a rotating cylindrical drum by tumbling the composition over heated pipes as it is gradually directed towards an output end of the drum, the improvement comprising adding an amount of petroleum hydrocarbon to achieve a laid down asphalt penetration of between 25 and 300 dmn at 77.degree. F. A further embodiment of the improved process comprises venting a mixture of hydrocarbon gases and moisture vaporized from the hot composition mixture at the output end of the apparatus, condensing the moisture and removing it and returning the hydrocarbon gases to a combustion chamber for providing heat to the apparatus tubes. Still another improvement comprises an apparatus modification wherein a plurality of relatively short pipes are disposed in the forward ends of the heating tubes through a front plate displaced from the forward end wall of the drum with the open pipe ends exposed to the combustion chamber for providing heat to the interior of the heating tubes.

Abstract: A method performs evaluation of properties of a clay rod, with which a honeycomb structural body is produced. The method mixes raw materials to produce a clay, and extrudes the clay and compresses the extruded clay to produce a clay rod. The method performs NMR to detect at least one of a T1 relaxation time and a T2 relaxation time in each of a normal part and an abnormality part extracted from the clay rod. Each of the T1 relaxation time and the T2 relaxation time corresponds to a relaxation time of nuclear spins of water protons magnetically excited in each of the normal part and the abnormality part. The method performs the evaluation of uniformity of a mixed state and a compression state of the clay rod based on a difference in T1 relaxation time and T2 relaxation time between the normal part and the abnormality part.

Abstract: A pug mill having a housing and a cantilevered shaft extending through the housing includes, in seriatim, a vacuum chamber, a wall, a mixing chamber and a reduction cone. A communication port about the shaft is positioned in the wall between the vacuum chamber and the mixing chamber. Vacuum can be maintained within the mixing chamber by air passing through the port. An auger associated with the shaft forces clay toward the reduction cone. This creates a seal for maintaining vacuum within the mixing chamber and extrudes cylindrical blocks of conditioned clay without significant air bubbles. A deflection plate rotating with the shaft and a spiral element about the shaft keep the communication port clear. The shaft is eccentrically mounted. The dividing wall is removable.
