Hopper capacity: 9m³*5
Asphalt hot mix plant LJB2000C is developed on the basis of Japan technology. The machines are suitable to mix kinds of asphalt mixture, widely used for the construction of high grade asphalt roads and urban roads. It is batching plant. Each aggregate, filler and bitumen are metered by electronic weigher. Industry control computer is used for operation to ensure the plant reliability.
To mix 2000kg asphalt each batch
If average moisture content of sand is 5%, and mixing cycle is 45s, output is 160 t/h (middle sized)
If average moisture content of sand is 5%, and mixing cycle is 60s, output is 120 t/h (small sized).
Material temperature: 140℃-160℃
Conditions concerned with output are as follows:
1. Average moisture content only refers the surface moisture content, moisture content inside will lower the output ability of drying drum.
2. Ambient temperature is 20℃.
3. Material density is 1600kg/m3.
4. Output includes filler and bitumen.
5. The proportion of aggregate must be correct and the specifications must meet the standard demand.
6. Filler density is 1120kg/m3.
