Abstract

Die Funktionsweise dieser Erwärmungs- und Mischanlage für Baustoffe beruht auf einer kontinuierlich oder diskontinuierlich arbeitenden, mischenden Bearbeitungsanlage, die mit in der Baumaschinentechnik bekannten mechanischen Arbeitsverfahren wie Fördermischen, Rührmischen, Trommelmischen, usw. unter gleichzeitiger Erwärmung die Baugüter, Baustoffe oder andere bautechnischen Substanzen arbeitet, um bestimmte, in der Bautechnik gebräuchlichen Mischgüter oder Produkte herzustellen oder zu verändern. Bei dieser Erwärmungs- und Mischanlage werden die wärmetechnisch zu behandelnden Baugüter je nach Prozesstechnik mit einem oder mehreren elektromagnetischen Feldern, die von einem oder mehreren Hochfrequenz- oder Mikrowellengeneratoren elektrisch erzeugt werden, berührungslos und homogen an der Oberfläche und im Volumen erwärmt. Der Erwärmungsprozess bewirkt auch eine Trockung der Baustoffe mit Feldenergie aus dem Hochfrequenzoder Mikrowellengenerator. How this heating and mixing system works for building materials is based on a continuous or discontinuous working, mixing processing plant that with mechanical known in construction machine technology Working processes such as conveying mixing, stirring mixing, drum mixing, etc. while heating the building materials, Building materials or other structural substances works to certain, common in construction technology Manufacture or change mixed goods or products. In this heating and mixing system, they are thermal building materials to be treated depending on the process technology with one or more electromagnetic Fields by one or more radio frequency or Microwave generators are generated electrically, without contact and homogeneous on the surface and in volume warmed up. The heating process also causes drying of building materials with field energy from the radio frequency or Microwave generator.
