ASPHALT MIXING PLANT
Asphalt mixing plant, comprising a mixing drum and a temperature monitoring system, the temperature monitoring system comprising a temperature sensor configured for contactless measurement of a material temperature of an asphalt mix to obtain at least a first temperature value for at least a first point of time, where the temperature sensor is arranged at an area of an output of the mixing drum or at a discharge chute of the mixing drum; and an operation and monitoring unit and a remote server; whereby the operation and monitoring unit is configured to wirelessly transmit the at least first temperature value to the remote server via a wireless communication interface unit.
SYSTEM AND METHOD FOR PRODUCING ASPHALT USING EXHAUST FROM A GENERATOR
A system for producing hot mix asphalt includes a generator having an exhaust port; a dryer drum having an inlet; a duct connecting the exhaust port to the inlet, the duct conveying a first flow of hot gas from the exhaust port; an exhaust bypass vent conveying a second flow of hot gas diverging from the first flow of hot gas; and a valve disposed at a junction between the duct and the exhaust bypass vent for adjusting a flow rate of the second flow of hot gas. The dryer drum produces hot mix asphalt from asphalt materials using a third flow of hot gas diverging from the first flow of hot gas and entering the dryer drum through the inlet.
System and Method for Recycling Asphalt through Radiant and Convection Heating and Simultaneous Gentle Tumbling
A system and method for recycling used asphalt material through convection heating and gentle tumbling recycles used asphalt material, such as reclaimed asphalt pavement, by uniformly and gradually applying radiant and convectional heating towards the used asphalt material. A radiant heating coil generates a controlled amount of radiant heat, at about 325 degrees, and up to 750 degrees Fahrenheit. At least one blower works to blow the radiant heat to the used asphalt material as convectional heat. An agitating conveyor simultaneously carries the used asphalt material while it is being heated. The agitating conveyor has a radiant heated conveyor floor that comprises depressions that work to agitate the used asphalt material. The uniform heating of the used asphalt material inhibits moisture from surging from the used asphalt material and maintains integrity of the subsequently formed rejuvenated asphalt. A rejuvenating chamber mixes the used asphalt material with a rejuvenating composition.
MOBILE ASPHALT PLANT
A mobile asphalt plant for producing asphalt includes a heating unit, a container unit, a plurality of augers, and an injector. The heating unit includes one or more heaters to generate heated gas, a tank to hold heat transfer oil, and one or more first plenum tubes extending from the heaters to within the tank. The first plenum tubes transport the heated gas to the tank to heat the heat transfer oil. The container unit includes a hopper to receive the aggregate material and one or more second plenum tubes extending from the one or more first plenum tubes and extending within the hopper. The second plenum tubes transport the heated gas from the first plenum tubes to heat the aggregate material. The augers are arranged as a series of augers, with a first one of the augers receiving the aggregate material from the hopper. Each of the augers conveys the aggregate material to a next one of the augers. Each of the augers heats the aggregate material using the heat transfer oil from the tank. The injector is connected to one of the augers and injects asphalt oil into the aggregate material to produce asphalt.
SYSTEM FOR PRODUCING HOT MIX ASPHALT
The present disclosure refers to the development of a hot mix asphalt plant mounted on a single fixed chassis with the correct dimensions for transport in a single shipping container. On this tubular structure chassis, two individual dosing silos fixed to the chassis and supported on metering conveyor, a rotary dryer, a two-axle pug mill mixer, an enclosed burner, a fuel pipe, bituminous binder tubing, exhaust pipe, bag filter, drag lift and a control cabin are disposed.
Chassis of mobile asphalt plants with side protectors
The present utility model pertains to the technical field of equipment for producing asphalt concrete (AC) or hot mix asphalt concrete (HMAC), and relates more particularly to an improvement to mobile asphalt plants provided with side protectors. Proposed are protective screens for the areas which should be avoided by operators and others, where high temperatures and noise levels prevail. The protectors are installed in the area where virgin aggregate arriving from the metering system is transferred to the drying/heating system, where the intake temperature of the metered material is high and elements such as the conveyor belt can cause injury to operators. The other area to be isolated is the place where the burner of the plant carries out the process of combustion.
Applied to chasis of mobile asphalt plants
An improvement to a chassis for mobile asphalt plants consists in modularizing the design of the chassis in order to reduce design time and storage costs by virtue of a standardization of the chassis. Thus, the solution fits asphalt plants of different sizes and reduces the physical space required to store items belonging to the structure of the chassis. The high level of standardization has been achieved by segmenting the main structure of the chassis into three regions which appropriately accommodate all of the systems for producing the asphalt mixture.
Cold in-place recycling machine with surge tank
A CIR-modified milling machine includes a milling drum that is adapted to mill material from a roadway, which milling drum is contained in a milling drum housing. An additive spray assembly is located within the milling drum housing and adapted to dispense an asphalt additive therein. An additive flow system includes an inlet line that is adapted to be operatively connected to an external supply line, a surge tank for asphalt additive that is in fluid communication with the additive spray assembly, and an additive pump for pumping asphalt additive from the surge tank to the additive spray assembly.
