LB Stationary Asphalt plant

LB Stationary Asphalt plant

Asphalt plant, also known as asphalt concrete mixing plant, is a complete set of equipment used for mass production of asphalt concrete. According to the mixing method, it can be divided into forced intermittent type and continuous production type; according to the transportation method, it can be divided into stationary type and mobile type. It can produce asphalt, modified asphalt, and colored asphalt, which is a necessary equipment for building expressways, graded highways, municipal roads, airports, and ports. Asphalt plant mainly consists of batching system, drying system, combustion system, hot material lifting, vibrating screen, hot material storage bin, weighing and mixing system, bitumen supply system, powder supply system, dust removal system, finished product silo and control system, etc. According to customer requirements, TRISUN supplies continuous stationary asphalt plants with an output of 20 to 100 tons per hour and intermittent stationary asphalt plants with an output of 60 to 400 tons per hour.

Q: What is the difference between continuous asphalt plant and intermittent asphalt plant? How to distinguish them?

A: The main difference between the two is whether there is secondary screening of the mixture. The aggregates are screened once to divide into several sizes. This is the first screening. The aggregate is mixed with bitumen in the mixing plant to form an asphalt mixture. If the aggregate is screened again during the mixing process, it is a second screening. The plant with secondary screening is intermittent, and the one without secondary screening is continuous.

Q: How to choose between continuous asphalt plant and intermittent asphalt plant?

A: Both continuous and intermittent plants have their own advantages and disadvantages. Continuous plant is suitable for large-scale production and high work efficiency, while intermittent plant is more suitable for small-scale production and rapid response to market changes.

1) Advantages and Disadvantages of Continuous Plants

The continuous type refers to continuous production within a specified time. Its advantages are that it is suitable for large-scale production, reduces downtime caused by production intervals, has high work efficiency, and can achieve high-quality and stable mixture production.

However, continuous type requires a high level of control technology and equipment, high maintenance costs, and high requirements on the supply of raw materials and fuels, which may require large inventories of raw materials and fuels. In addition, raw materials and fuel need to be added continuously during the production process, which occupies a relatively large area.

2) Advantages and Disadvantages of Intermittent Plants

Intermittent type is to produce at certain time intervals. After adding raw materials and fuel, the production process is interrupted, and production is restarted after the raw materials and fuel are consumed. The advantage of intermittent plant is that the production plan can be flexibly adjusted according to demand. In addition, the equipment cost of intermittent plant is relatively low, the requirements for raw materials and fuel supply are not high, and the floor space is relatively small.

However, the intermittent plant production process requires multiple starts and stops, and does not have the stability and efficiency of continuous plants. At the same time, combustion energy will be wasted during shutdown, and more manual operations will be required, increasing labor costs.

3) Conclusion and suggestions

Continuous plant and intermittent plant each have their own advantages and disadvantages. It is recommended to combine the production plan and market demand in the design of the plant, and select the corresponding production method according to the actual situation.
