Differences between Mobille Continuous Asphalt Plants and Mobille Drum Asphalt Plants:

One: Different Drying Methods
From an external perspective, the drum of a continuous mixing plant (Drum-type) dries and heats the aggregate before mixing it to produce finished asphalt. In contrast, the continuous forced-mixing plant (Drum-type) only serves to dry the aggregate; mixing takes place within a forced-mixing drum to produce finished asphalt.
Structurally, because the continuous forced-mixing plant (Drum-type) only functions as a dryer, it uses a counter-current installation method to ensure the aggregate outlet temperature. In contrast, because the continuous drum-type plant (Drum-type) mixes the asphalt inside the drum and to prevent the asphalt from contacting open flames, it uses a co-current installation method.
(Extended explanation: Aggregate outlet direction on the same side as the burner is counter-current; aggregate outlet direction opposite to the burner is co-current.)

II. Different Mixing Methods
Continuous drum mixers heat cold aggregates in the near-fire zone within a co-current drum, while asphalt is sprayed into the far-fire zone for mixing. Continuous forced-mix mixers, on the other hand, heat cold aggregates in a counter-current drum before spraying asphalt into a mixing bowl for forced mixing.
III. Different Applications
Depending on the application, drum mixers, lacking a mixing bowl, cannot accommodate additives. Continuous forced-mix mixers, with their mixing bowl, allow for the addition of various mineral powders and additives, offering greater adaptability.
