Abstract
LA INVENCIÓN SE REFIERE A UN MÉTODO PARA PRODUCIR UN GRANULADO EXPANDIDO (2) HECHO DE UN MATERIAL MINERAL EN FORMA DE GRANO DE ARENA (1) USANDO UN PROPELENTE; EN DONDE EL MATERIAL SE TRANSPORTA A LO LARGO DE UN CAMINO DE TRANSPORTE (5) A TRAVÉS DE MÚLTIPLES ZONAS DE CALENTAMIENTO (6) EN UN EJE DE HORNO (4); EL MATERIAL (1) SE CALIENTA A UNA TEMPERATURA CRÍTICA A LA CUAL LAS SUPERFICIES DE LOS GRANOS DE ARENA (1) SE PLASTIFICAN, Y LOS GRANOS DE ARENA (1) SE EXPANDEN EN BASE AL PROPELENTE; EL MATERIAL SE ALIMENTA DESDE EL FONDO JUNTO CON UNA CANTIDAD DE AIRE; EL MATERIAL (1) SE TRANSPORTA DESDE LA PARTE INFERIOR A LA PARTE SUPERIOR A LO LARGO DE LA RUTA DE TRANSPORTE (5) POR MEDIO DE LA CANTIDAD DE AIRE QUE FLUYE DESDE LA PARTE INFERIOR A LA PARTE SUPERIOR EN EL EJE DEL HORNO (4) Y LOS GRANOS DE ARENA (1) SE EXPANDEN EN LA MITAD SUPERIOR DE LA RUTA DE TRANSPORTE (5). DE ACUERDO CON LA INVENCIÓN, EL MATERIAL (1) SE CALIENTA DE MANERA QUE EL MATERIAL (1) INMEDIATAMENTE ANTES DE ENTRAR EN EL EJE DEL HORNO (4) ESTÁ A UNA TEMPERATURA DE ENTRADA DE MATERIAL (T3) QUE ES INFERIOR A LA TEMPERATURA CRÍTICA Y SUPERIOR A LA TEMPERATURA AMBIENTE (RT).THE INVENTION REFERS TO A METHOD FOR PRODUCING AN EXPANDED GRANULATE (2) MADE OF A MINERAL MATERIAL IN THE FORM OF SAND GRAIN (1) USING A PROPELLANT; WHERE THE MATERIAL IS TRANSPORTED ALONG A TRANSPORTATION ROAD (5) THROUGH MULTIPLE HEATING ZONES (6) ON A OVEN SHAFT (4); THE MATERIAL (1) IS HEATED TO A CRITICAL TEMPERATURE AT WHICH THE SURFACES OF THE SAND GRAINS (1) ARE PLASTIFIED, AND THE SAND GRAINS (1) ARE EXPANDED BASED ON THE PROPELLANT; THE MATERIAL IS FEED FROM THE BOTTOM TOGETHER WITH A QUANTITY OF AIR; THE MATERIAL (1) IS TRANSPORTED FROM THE BOTTOM TO THE UPPER PART ALONG THE TRANSPORT ROUTE (5) BY MEANS OF THE AMOUNT OF AIR FLOWING FROM THE BOTTOM TO THE UPPER PART IN THE SHAFT OF THE OVEN (4 ) AND THE SAND GRAINS (1) EXPAND IN THE UPPER HALF OF THE TRANSPORT ROUTE (5). ACCORDING TO THE INVENTION, THE MATERIAL (1) IS HEATED IN A WAY THAT THE MATERIAL (1) IMMEDIATELY BEFORE ENTERING THE OVEN SHAFT (4) IS AT A MATERIAL INLET TEMPERATURE (T3) WHICH IS LOWER THAN THE TEMPERATURE CRITICAL AND HIGHER THAN AMBIENT TEMPERATURE (RT).
