# LB2500 Stationary Asphalt Mixing Plant (200t/h)

The LB2500 stationary asphalt mixing plant is a batch‑type medium‑large asphalt mixing unit with rated capacity of 200 tons per hour. It supports both manual and fully‑automatic operation modes, widely used for large‑scale asphalt mixture production of high‑grade highways and municipal roads. Standard power supply: 380V‑50Hz, 3‑phase, adjustable according to site conditions. Featuring high weighing accuracy, fast mixing speed and qualified dust emission, it is suitable for large‑volume continuous asphalt production.
