Asphalt Mixing Plant

1. Cold Aggregate Supplying System

It consists of hopper, belt feeder and aggregate belt conveyor. The main function is to deliver cold aggregate through belt feeder to aggregate belt conveyor according to the certain proportion. The over-sized cold aggregate will be ruled out by the primary screen. Then transport the aggregate to dryer drum through belt conveyor.

Features:

Belt feeder is driven by frequency conversion speed regulation motor;

Special outlet can prevent belt from abrasion;

Missing Material alarm device can inform operator timely.

2. Drying and Heating System

The burner is installed on the outlet of dryer drum. Dryer drum tilts towards outlet and the cold aggregate can be heated in the dryer drum. There is temperature testing device at the end of dryer drum, which can control the aggregate temperature.
