The drum asphalt mixing plant adopts a continuous production process for asphalt mixtures, and is therefore also known as a continuous asphalt mixing plant, in contrast to batch-type plants. In some countries and regions, it is also referred to as an asphalt drum mixing plant, drum-type asphalt plant, or drum asphalt production plant.

The DAP series features a simple structure, easy operation, and low running and maintenance costs. With a production capacity of 40–240 tons per hour, it is suitable for small- to medium-sized road construction projects.

Key Features

1. Compact Size and Structure
   Small footprint and compact design allow installation in narrow or confined areas, offering flexible and convenient operation.
2. Easy Transport and Relocation
   Compared to batch-type asphalt plants, the DAP series does not require a mixing tower, making transportation, installation, and relocation more convenient.
3. Precise Cold Aggregate Feeding
   Cold aggregate feeders are equipped with weighing sensors and variable frequency motors, enabling accurate control of aggregate feeding rates.
4. High-Efficiency Drying Drum
   The drying drum combines heating, drying, and mixing functions for improved energy efficiency. Optimized internal structure and external insulation accelerate heating and minimize heat loss.
5. User-Friendly Operation and Maintenance
   Designed for intuitive operation and simple maintenance, ensuring ease of use.
6. Low Investment, High Cost Efficiency
   Low initial investment and economical operation make it ideal for small- to medium-scale projects.

Main Components

1. Aggregate Feeder
   Conveyor belt driven by a variable-speed motor for adjustable feed rates. Each hopper is equipped with a weighing scale for precise measurement.
2. Asphalt Tank
   Direct heating tank with thermal oil heating, optional electric heating available to ensure stable asphalt quality.
3. Burner
   High-efficiency burner from an internationally recognized brand, fuel-saving. Diesel, natural gas, or heavy oil can be used according to project requirements.
4. Drying and Mixing Drum
   Counterflow drum with integrated drying and mixing functions. Optimized internal design ensures superior drying and mixing performance.
5. Hot Asphalt Elevator
   Chain-bucket elevator transports hot aggregates to the hot storage bin. Fully enclosed and insulated to prevent heat loss.
6. Hot Storage Bin
   Elevated bin for temporary storage of finished asphalt mixtures. Bin volume and discharge height are adjustable according to project needs.
7. Control Panel
   PLC control system for user-friendly operation. Electrical components use Siemens products for reliability and long service life.
8. Mobile Chassis
   Optional mobile chassis can be added to the main module for quick transport and easy relocation of the plant.
