      Environmental Multi-function Asphalt Mixing Plant

      Features
      (1) Versatility: With the multi-functional connector, the asphalt mixing plant can be equipped with environmental protection facilities, hot recycling equipment, cold recycling equipment and other equipment, and process colored asphalt and various additives. It can be slightly retrofitted and become a two-in-one mixing plant for bituminous mixture and cement concrete.
      (2) Economy: The high-precision measurement ensures the lowest production cost. The most advanced burner minimizes the fuel consumption. A large number of maintenance-free structures and parts reduce the maintenance cost for the user.
      (3) Reliability: The advanced technology and the high-level configuration ensure a stable and reliable running.
      (4) Modular structure design: The plant can move quickly to another site. It facilitates the transportation, the installation and the commissioning.
      (5) Safety and comfort: The space structure is designed according to ergonomic design. The asphalt mixing plant is nice, comfortable and convenient, while safe and reliable.
