A combination of components is provided for use in making asphalt concrete from a plurality of aggregate material streams. The combination includes an indirect dryer for heating aggregate material from a first material stream without directly exposing said first stream material to hot gases of combustion. The combination also includes a mixer for mixing aggregate material from the first material stream, aggregate material that has not been heated in the indirect dryer from a second material stream, and a binder component to produce asphalt concrete.

A method of treating a material to recover an oil from the material comprises heating the material to evaporate the oil, removing gas phase fluids from the material, and separating the oil from the gas phase fluids removed from the material, wherein the method includes mixing hot vapour with the material. The material being treated in the chamber is heated by friction within the chamber generated by a rotating shaft and flail. Injection of hot vapour improves the efficiency of the process to separate oil and any other evaporable liquids at lower temperatures. The thermal energy generated within the chamber is not consumed in changing the phase of large quantities of liquids in the material, and more of the energy generated is available to heat up the material and evaporate the oil fractions from the solids.

An apparatus, a system, and a method for heat treating a moisture-containing or water-laden material are provided. The heat treatment can be drying for dehydration, gasification, or full carbonization. The system comprises a feeding mechanism, and a rapid compression (RCU)apparatus having a screw, a barrel, and one or more flow disrupters. The system can further include a reflux condenser, an aftercooler stage, a second condenser for particle filtering, and an exit mechanism. The one or more flow disrupters are located on an inner surface of the barrel and projects into the passageway created by the screw and the barrel. The screw is sized to fit within the barrel such that flow disrupter does not contact the screw. The one or more flow disrupters cause the water-laden material to fold over onto its self, thereby, allowing for the occurrence of more uniform drying.

A method of making water absorbing resin according to the present invention includes a polymerization step for producing a water absorbing resin by reverse-phase suspension polymerization; and a drying step for drying the water absorbing resin obtained in the polymerization step. In the drying step, the drying is made by using a dryer (X1) which includes: an end wall (21), an opposite end wall (22), a circumferential wall (23) and a rotation shaft (24) between these end walls, stirring means (25) provided in the rotation shaft (24) for stirring the water absorbing resin while moving the resin from the end wall (21) to the end wall (22), and stirring means (26) provided in the rotation shaft (24) between the stirring means (25) and the end wall (22) for stirring the water absorbing resin while moving the resin from the end wall (22) to the end wall (21).

The apparatus includes a channel having an inlet end for receiving particulate material to be dehydrated and an outlet end for discharging the particulate material in a dehydrated condition. A screw conveyor rotatably mounted in the channel advances the particulate material while stirring the particulate material to enhance the release of water and noxious vapors. A fan creates an air current in the channel to entrain water and noxious vapors released by the particulate material. The vapors are directed toward a heating chamber which incinerates dangerous and odoriferous compounds as much as possible. The resulting gaseous media is directed through a passage in a heat-exchange relationship with the channel to elevate the temperature of the particulate material that is being processed and to cause same to release water and noxious vapors. The passage is isolated from the channel to avoid direct contract between the burned gases that are released in the atmosphere with yet unburned gases aspirated from the channel.

A dryer densifier includes a hopper for receiving wet, dry and/or flaky thermoplastic waste material. The hopper feeds an auger barrel which is heated and insulated whereby material passing therethrough may be dried and fused together with other material. The auger barrel and screw are configured to leave sufficient space therebetween whereby heated vapors may pass along the length of the auger and exit to the atmosphere at the discharge end, and whereby the heated vapor may be collected by a vapor collecting hood. The material is discharged from the auger onto a shaker screen table where the fused and unfused materials are separated by the vibrating screen conveyor of the table. The unfused material is returned to the receiving hopper for further densification and the fused material is conveyed to a granulator, whereupon the dried and densified material is granulated.

An apparatus and a process for treating household refuse are disclosed. Household refuse or garbage is comminuted, dried and mixed with granular mineral substance, preferably sand, at a temperature of up to 1000.degree. C. and the mixture is homogenized and degassed by the contact of the refuse with the hot sand until the garbage and refuse has been reduced in volume to a desired degree.

An improved method and apparatus for removing moisture from a wet material. The apparatus is of the type having: an elongated trough having at least one level for containing the material, the trough having an upward open portion, a downward closed portion, a feed end for receiving the material and a delivery end for discharge of the material; means, associated with the trough, for conveying the material contained in the trough from the feed end to the delivery end; a heat plate for generating a radiant heat mounted along substantially the entire length of the open portion of each level of the trough such that the material conveyed in each level of the trough is exposed to the radiant heat in order that a portion of the moisture in the material may be evaporated; means, operatively connected to the heat plate, for controlling the temperature of the heat plate in order that the radiant heat is generated in a controlled manner such that a desired temperature of the material throughout each level of the trough may be maintained; and means, associated with the trough, for collecting the moisture evaporated by the radiant heat. The heat plate is preferably electrically heated. The method for removing moisture from the wet material is performed by using the apparatus.
