2. Description of the Related Art A dryer having almost the same structure as that of a new aggregate heating dryer of an asphalt plant is used for recycling asphalt pavement waste materials (hereinafter referred to as "waste materials") dug up by road construction or the like. This regeneration dryer rotatably supports a cylindrical drum, and the hot air sent from the burner while rolling down the waste material while scraping up the scrap material with a large number of scraping blades installed around the inner circumference of the drum. The waste material is regenerated by heating it to a desired temperature.

When the waste material is heated and regenerated by the dryer, the asphalt adhering to the surface of the waste material is melted while the waste material is rolling down in the drum while being heated, so that the waste material becomes adhesive. This adhesive waste material may gradually adhere to and grow on the scraping blades and the inner circumference of the drum, and eventually impair the function of the scraping blades.As a preventive measure, for example, a chain loosened on the scraping blades may be used. You can also see that there is a movable scraping blade to prevent the sticking by giving a shock to the scraping blade and the inner peripheral wall of the drum when the drum rotates.
