20100238757 | Apparatus, System, and Method for Adding a Liquid in a Mixing Process - An apparatus, system, and method are disclosed for adding a liquid in a mixing process. The apparatus in the described embodiments includes a liquid inlet, a continuous flow heater, a holding tank, a support structure, and a metering device. The continuous flow heater is coupled to the liquid inlet. The holding tank is adapted to be coupled to the continuous flow heater and to receive heated liquid from the continuous flow heater. The support structure is configured to support the holding tank at a height greater than approximately four feet above a ground level. The metering device is coupled to the holding tank and has an indicator for identifying an amount of liquid dispensed from the holding tank. | 09-23-2010 |
20110110177 | System for producing asphalt from reclaimed asphalt pavement - A system for producing asphalt from RAP including a conveyor belt, a source of fuel, at least one infrared chamber, at least one rotary mixer, and an asphalt producing module, preferably a drum heater. The system includes measures for carefully controlling the heat of the reclaimed asphalt pavement as it is dried, including controls for adjusting the distance between the infrared chambers and the conveyor belt, controls for turning each individual infrared chamber on and off, and controls for adjusting the rate of the conveyor belt and the rotary mixers. | 05-12-2011 |
20130294187 | APPARATUS FOR APPLYING HOT MIX FOR TAR SEALED ROADS - An apparatus for preparing a hot mix including aggregate and bitumen includes a cylindrical vessel incorporating a mixing chamber having a rotating paddle assembly mixing aggregate and bitumen. A heating chamber is below the mixing chamber, separated by a dome shaped separating element, the center of which is above its periphery. The heating chamber's lower part has a diameter less than that of its upper part. A blower forces air into the lower part through a horizontal passage with a burner heating the air. The axis of the passage is offset from the vertical axis of the heating chamber. The heated air spirals upwardly and outwardly through the lower and upper parts of the heating chamber, traversing the separating element before exiting through apertures about the periphery of the separating element. The mix is heated by the heat transferred from the air as it passes over the separating element. | 11-07-2013 |
20150314482 | VOLUMETRIC MIXER WITH WATER TANK AND OIL TANK INSIDE AGGREGATE BIN - A mobile concrete mixing unit has an aggregate bin divided into two compartments by a water tank provided within the aggregate bin. A hydraulic reservoir is provided within the water tank in order to cool the hydraulic fluid within the hydraulic reservoir and warm the water within the water tank. The water tank also helps to keep the aggregate warm and flowable when used in low temperatures. A lower portion of the water tank includes sides that slope inwardly so that aggregate within the bin can drop freely onto a conveyor belt without bridging between the water tank and the sidewalls of the aggregate bin. | 11-05-2015 |
