Abstract
In a drying cylinder for virgin inert material, inside which the inert material I is fed against the flow of the hot gases G, the recovered conglomerate, referred to as recycled product R, is introduced into an annular chamber 24 separated from the chamber for the virgin inert material by means of a wall 26 which is gas-tight but able to transmit heat. The recycled product travels in the same direction as the virgin inert material and emerges, heated, from the same end from where the inert material is discharged and together they are conveyed to a mixer; any harmful gases produced by heating of the bitumen contained in the recycled product are sucked away from said discharge end and made to pass through a high- temperature zone which causes combustion thereof. <IMAGE>
