Abstract

PROCESSO E USINA PARA USINAR ASFALTO A QUENTE, PARA PRODUZIR MISTURAS ASFáLTICAS QUENTES MELHORES E MAIS RESISTENTES. Refere-se a presente mvenção a um processo e uma usina (1) para usinar asfalto a quente, para produzir misturas asfálticas quentes melhores e mais resistentes, sem chama direta nos agregados minerais, com maior tempo para secar, aquecer e misturar os agregados com o asfalto, o que permite baratear e melhorar em muito a mistura asfáltica quente, alimentando-se os agregados por uma entrada de alimentação (2), sendo os agregados e a carga "filer" misturados, gradualmente, na usina de asfalto, com um secador e misturador, paralelo em relação à horizontal, através de eixos removíveis de rotação (3) com paletas e um variador de velocidade para cada função de secar, misturar e sair, a uma temperatura de 150° a 160°C, sendo então colocado o asfalto a uma temperatura de 160° a 170°C, em bateladas (traços) de até 500 toneladas, única, sendo os agregados misturados em cada traço por, no minimo, vinte e cinco minutos (secos) e, no máximo, trinta minutos (molhados), independentemente da quantidade fabricada, podendo os agregados estar estocados e expostos ao tempo o que não altera a qualidade da mistura, onde todo o calor de aquecimento é provido por meio de condução térmica seguido de irradiação e convecção nas partes inferior e laterais, sem retomo mecãnico forçado das partículas da poeira através de parafuso sem fim e válvula recuperadora de fmos ou caracóis extratores.HOT ASPHALT MACHINING PROCESS AND MACHINE, TO PRODUCE BETTER AND MORE RESISTANT HOT ASPHALT MIXTURES. The present invention relates to a process and a plant (1) for hot asphalt machining, to produce better and more resistant hot asphalt mixtures, without direct flame in mineral aggregates, with longer time to dry, heat and mix the aggregates with asphalt. asphalt, which makes it possible to cheapen and greatly improve the hot asphalt mix by feeding the aggregates through a feed inlet (2), and the aggregates and the filer load are gradually mixed into the asphalt plant with a dryer and mixer parallel to the horizontal by means of removable rotary shafts (3) with pallets and a speed variator for each drying, mixing and leaving function at a temperature of 150 ° to 160 ° C and then placed asphalt at a temperature of 160 ° to 170 ° C, in batches (strokes) of up to 500 tonnes only, with aggregates mixed in each stroke for at least twenty-five minutes (dry) and at most thirty minutes (wet), indepen notably the amount manufactured, and the aggregates can be stored and exposed over time which does not change the quality of the mixture, where all heating heat is provided by thermal conduction followed by irradiation and convection on the undersides and sides, without mechanical return. forced dust particles through a worm screw and recovery valve for extracting ends or snails.
