The classification of asphalt mixing plant is explained in the following paragraph. If you want to learn the more specific introduction, click asphalt mixing plant types.

Main Purposes of Asphalt Mixing Plant

Asphalt mixing plant, also known as asphalt concrete mixing plant, refers to a complete set of equipment used for mass production of asphalt concrete, which can produce asphalt mixture, modified asphalt mixture and color asphalt mixture. It is necessary equipment for building expressways, grade highways, municipal roads, airports and ports.

Integral Parts of Asphalt Mixing Plant

Asphalt mixing equipment is mainly composed of batching system, drying system, combustion system, hot material lifting, vibrating screen, hot material storage bin, weighing and mixing system, asphalt supply system, powder supply system, dust removal system, finished product silo and control system.

The subdivided components are as follows: grading machine, vibrating screen, belt feeder, powder conveyor, dry mixing drum, pulverized coal burner, dust collector, elevator, finished product silo, asphalt supply system, power distribution room, electrical control system.

Classification of Asphalt Mixing Plant

According to the production capacity, it can be divided into: small, medium and large asphalt plant.

Small type asphalt mixing plant is the plant that the capacity is 80 t/h and below.

Medium type asphalt mixing plant is the plant that the capacity is 100 t/h to 240 t/h.

Large type asphalt mixing plant is the plant that the capacity is 320 t/h and above.

According to the transportation mode (migration mode), it can be divided into mobile, semi stationary and stationary asphalt plant.

Mobile asphalt mixing plant, that is, the silo and mixing pot are equipped with tires, which can be transferred with the construction site. It is applicable to county and township highways and low-grade highway projects;

Semi stationary type asphalt plant, that is, the equipment is installed on several trailers and assembled at the construction site, which is mostly used for highway construction;

Stationary type asphalt mixing plant, that is to say, the equipment operation site is fixed, also known as asphalt concrete processing factory, which is suitable for project concentration and urban road construction.

According to the process flow (mixing mode), it can be divided into continuous drum type and intermittent forced type.

Continuous drum type asphalt plant, that is, continuous and uninterrupted mixing mode is adopted for production, and the heating and drying of aggregates and mixing of mixtures are carried out continuously in the same drum;

Forced intermittent type asphalt plant, that is, the heating and drying of aggregates and the mixing of mixtures are forced to be carried out periodically. The equipment stirs one pot at a time, and each pot takes 45 to 60 seconds. The output depends on the equipment model.

At present, highway projects are generally large investment projects. In the actual project construction, it is very necessary to control the cost of the project. The control of the cost of the asphalt plant in the highway project plays a great role in controlling the cost of the whole highway project, because the main expenses of the highway project are concentrated in the mixing plant.The cost control of asphalt plant shall start from the project budget of highway engineering.

In the budget of the asphalt plant, the impact of various factors on the cost of asphalt plant shall be fully considered, such as the reasonable site selection, the selection of asphalt production materials, the selection of transportation schemes, the selection of production equipment, and the design of production processes.

In the budget stage, it is required to have managers who are proficient in technical requirements and budget ability to make reasonable cost budget, and optimize various alternative production plans on the basis of ensuring production quality, so as to reduce production costs.

When carrying out specific production and processing in the asphalt plant, first of all, the coordination role of employees should be fully played. In different equipment operations, appropriate operators should be equipped to avoid additional production costs due to improper use of employees.

Secondly, the asphalt plant needs to consume a large amount of energy materials. In the current era of increasing energy shortage, the price of energy materials is increasing. Therefore, it is necessary to select these energy materials appropriately. Under the condition that all equipment in the asphalt plant can operate normally and stably, energy materials can be selected reasonably and economically, so as to effectively control the production cost of the asphalt plant while improving the utilization of energy materials.

Thirdly, as a large amount of materials are required for the production of the asphalt plant, the transportation cost will follow. Therefore, it is necessary to select the appropriate transportation scheme of materials to avoid waste. In order to implement the cost control of material transportation, a special transportation supervision department can be set up to reasonably regulate the transportation. The transportation of materials shall be carried out according to the budget plan as far as possible to avoid the additional.

In addition, before large-scale mixture production in the asphalt plant, it should also be noted that the temperature of the mixing pot should not be too low, otherwise the mixture produced by the mixing pot will be unqualified, which will cause waste of asphalt mixture in use.

In short, in the large-scale production of asphalt mixing, it is necessary to weigh the factors affecting the production cost. After the budget of production cost is completed, the production shall be carried out according to the budget plan. In the actual production process, it is necessary to give full play to the coordination role of all aspects, reasonably organize production materials, select appropriate energy materials, select reasonable material transportation plan, and pay attention to some details in the asphalt mixing and processing process, so as to truly realize the effective and reasonable control of production cost.
