.Fine aggregate Leak Big aggregate spreade Heating

摘要

This paper proposes a dryer wing (1) to produce aggregate asphalt inside the dryer to produce asphalt road pavement material. Dryer Wing).;The top of the dryer wing (1) in this paper is wide to form a wide spread surface (2), and the bottom is narrow to form a narrow surface (3), and the spread angle (6) is formed when the heating aggregate falls. do. On the wall, it forms a large number of gaps (4) to escape the fine aggregate, and on the upper surface to form the aggregate pick-up angle (5) to hold the heating aggregate while the fine aggregate is pulled out and the coarse aggregate is pulled up to 20 degrees The heating temperature is heated to the nob and the fine aggregate is related to the cold aggregate heating to ensure that the heating temperature is lowered. The configuration and detailed description are as follows.;Upper surface Wide spread surface Narrow surface Aggregate space to be broken out Aggregate Pick up Angle 20 degrees Unfold angle Dryer wing Assembly mounting angle
