Asphalt mixing plant is a complete set of equipment for mass production of asphalt concrete, which is also called asphalt concrete mixing plant. It is necessary machine for the construction of highways, grade roads, ports, municipal roads, airports and so on. According to the way of its mixing, asphalt mixing plant can be divided into compulsory asphalt concrete mixing plant and drum continuous asphalt concrete mixing plant. According to its method of movement, it has two types, stationary asphalt mixing plant and mobile asphalt mixing plant. What’s more, it consists of small, medium and large asphalt mixing plant according to its production capacity.

1. Feeding belt is designed with baffles, which makes material feeding system steady and smooth.

2. Optimized flights structure of drying drum makes the drying system more effective and stable.

3. Hot elevator adopts the double chain for hoisting, which not only prolongs the service life of the hoisting machine but also improves the running stability.

4. Linear-mode screen driven by imported vibrator improves the screening efficiency and reduces the failure rate of plant.

5. Large capacity hot aggregate bin makes operation more convenient.

6. Unique designed paddles and the powerful mixer allow the mixing operation easier, effective and reliable.

7. The combination of gravity removal and bag dust removal makes our asphalt mixing plant eco-friendly and economical.

1. Integrated design, optimized composition: Divided into eight separate units, compact structure; each unit is independent system.

2. Convenient transportation, fast relocation: Each individual unit is equipped with chassis wheel structure, and does not require special vehicles for transport.

3. Quick installation, time and labor saving: It takes only few days to install, no need of large-ton cranes, no cutting and no welding.

4. Without foundation, environment-friendly and cost saving any flat and firm ground can be suitable for this plant to be installed on, no need for large amount of ground-based construction and reduce transportation cost.

1. High productivity and low energy consumption: Because the continuous mixing plant is continuously feeding and discharging, it has high productivity. The materials of the continuous mixing plant are continuously passed through the mixer in turn, so the mixing speed is faster and the energy consumption is relatively low.

2. The process of drum continuous asphalt mixing plant is simple.

3. Saving time: Drum continuous asphalt mixing plant has good continuity, which can effectively save time and shorten the construction period.

4. Easy maintenance: Due to its stable performance and low failure rate, the drum continuous asphalt mixing plant is easy to maintain. It also can reduce the cost.

Asphalt mixer plant—Batch type

1. High grading accuracy: The batch asphalt mixing plant has a secondary weighing system, which can ensure the gradation of aggregate. It makes the ratio of aggregate and bitumen more accurate.

2. Changing the gradation of aggregate and the ratio of oil and stone at ant time: Because of its intermittent mixing that means separately mixing and discharging, the gradation of aggregate and the ratio of oil and stone can be changed at any time. Therefore, the performance of asphalt concrete is relatively good, which can meet the need of different construction projects.

3. The requirement for aggregate is not high.

According to production capacity of asphalt mixing plant

If its production capacity is below 40 tons per hour, it is named small-sized asphalt mixing plant; if its production capacity is between 40 tons and 400 tons per hour, it is called medium-sized asphalt mix plant; if its production capacity is above 400 tons per hour, it is named large asphalt mixing plant.

Components of Asphalt Mixing Plant

Asphalt mixing plant includes cold aggregate feeding system, drying drum, vibrate screen, weighing system, bitumen supplying system, mixing system, dust collecting system and control system, etc.

asphalt plant structure

Cold aggregate feeding system: The cold aggregate of different specifications is fed into the cold bin by loader. These cold aggregates are collected to the aggregating belt and transported to the oblique belt.

Drying drum: It is mainly used for drying the cold aggregate.

Hot aggregate elevator: It mainly conveyed the dried hot aggregate to the vibrating screen.

Vibrating screen: The vibrating screen of batch mix asphalt plant classifies the hot aggregates and sends them into the hot aggregate storage bin.

Weighing system: Based on the ratio of asphalt mixture, the weighing system weighs aggregates, powders and bitumen separately, and unloads them into the mixing device.

Mixing system: Mix the weighed materials.

Control system: The control system is used to control the weighing door, discharge door, valve and so on. The operation of the control system will directly affect the accuracy and performance of the mixing equipment.

Dust collecting system: In the process of drying the cold aggregate, it is inevitable to produce dust. Dust collecting system of asphalt concrete plant aids to remove the dust and sends the dust to the recycling powder storehouse to reduce the environmental pollution.
