Main technical parameters of Hot Mix Asphalt Plant
1. Under standard operating conditions
The standard working condition of the mixing plant refers to the working condition when the ambient temperature is 20°C, the standard atmospheric pressure, the average moisture content of the cold aggregate is 5%, the hot aggregate temperature is 160°C, the batch cycle time is 45s, and the finished material is medium-grained.
2.Model Code
The meaning of the code is as follows:
Group code: LB, is a combination of the pinyin initials of the words "Li" and "Qing" in the asphalt mixing plant.
Type code: G─fixed (can be omitted); Y─mobile type.
The basic models stipulated by the Country are model 1000, 2000, 3000, 4000, and other models are derived from these models, such as: model 750, 1500, 2500, 3500, etc.
3.Design capacity
The design of asphalt mixing equipment mainly refers to the capacity of the mixer, which is mainly for the batch type. The capacity of batch asphalt stations varies from manufacturer to manufacturer, but basically there are 1000 kg, 2000 kg, 3000 kg, and 4000 kg.
4.Working period
The productivity of asphalt mixing plant is determined by the capacity of the mixer and the working cycle. The working cycle refers to the time difference from the discharging of the mixer to the next discharging. Under standard working conditions, it is generally 45s. But for continuous type, there is no duty cycle.
5.Productivity
Productivity refers to the hourly output of asphalt mixing plant under standard conditions. For batch asphalt mixing plant, the rated production rate is used to calibrate the production capacity of the plant. For example: 1000 type rated productivity is 120t/h; 2000 type rated productivity is 160t/h; 3000 type rated productivity is 240t/h; 4000 type rated productivity is 320t/h.
6.Installed power
Installed power refers to the sum of the rated power of all electrical equipment for a set of asphalt mixing plant.
7. Fuel consumption
Fuel consumption refers to the weight of fuel consumed by the burner on the drying drum to produce 1 ton of qualified finished materials.
8. Emission index
The environmental emission indicators of asphalt mixing plant are two aspects. One is the pollutant emission concentration, and the other is the pollutant emission blackness. According to national standards, the smoke emission concentration of asphalt mixing equipment is ≤100mg/Nm3, and the smoke emission blackness does not exceed Ringelmann blackness level I
9.Measurement accuracy
Asphalt mixture is designed strictly according to the ratio of aggregate, asphalt, mineral powder, and additives. Therefore, controlling the measurement accuracy of aggregate, asphalt, mineral powder or filler, and additives is the guarantee of the quality of the components of the asphalt mixture. According to national standards, the measurement accuracy of asphalt mixing equipment is divided into static and dynamic measurement accuracy.
