Example Embodiment

[0029] The present invention will be further described below through specific embodiments.

[0030] Reference Figure 1 to Figure 2 As shown, high-quality asphalt mixture production equipment includes aggregate supply system 1, drying heating system 2, negative pressure dust removal system 3, intermittent asphalt mixture mixing system 4, finished material storage system 5, and powder supply System 6, asphalt storage system 7, special component addition system 8, fine aggregate processing system 9 and operation room 10;

[0031] The aggregate supply system 1 includes a multi-stage aggregate bin 1.1 and a conveyor belt 1.2. The aggregate in the aggregate bin 1.1 is sent to the drying and heating system 2 through the conveyor belt 1.2, which can realize the storage, distribution, and distribution of cold aggregates. Measurement

[0032] The drying heating system 2 includes a drying drum 2.1 and a burner 2.2. Through the burner 2.2, the aggregate in the drying drum 2.1 can be dried and...

Abstract

The invention relates to the field of asphalt mixture production, and specifically relates to production equipment for a high-quality asphalt mixture and a production method thereof. The production equipment for the high-quality asphalt mixture comprises an intermittent asphalt mixture stirring system and a fine aggregate treatment system, wherein the fine aggregate treatment system comprises an air separation device, a negative pressure dust removal and recovery device, a fine aggregate storage device, and a fine aggregate metering and conveying device. According to the production equipment for a high-quality asphalt mixture and the production method provided by the invention, by adding the fine aggregate treatment system, fine aggregates can be independently broken and sieved, and stored and metered, and directly poured in an asphalt stirring main machine without the need of further heating of a drying drum to carry out asphalt mixture production; compared with the previous production equipment for an asphalt mixture, because fine aggregate grading is strictly ensured, the structure is capable of greatly improving the asphalt mixture, reducing energy consumption, and meeting the production needs of the high-quality asphalt mixture.

Description

technical field [0001] The invention relates to the field of asphalt mixture production, in particular to high-quality asphalt mixture production equipment and a production method thereof. Background technique [0002] With the continuous construction and improvement of my country's infrastructure, by the end of 2013, the mileage of my country's expressways has been close to 104,000 kilometers, and most of them are asphalt roads. Under the new form of rapid development of transportation. Many changes have taken place in highway construction at home and abroad, and the research results on asphalt mixtures at home and abroad have been further deepened. [0003] Fine aggregate is an important part of asphalt mixture, which has a great influence on the quality and performance of asphalt mixture. Many domestic customers will also research and design formula through experiments. Due to the limitations of traditional asphalt mixture screening settings in existing asphalt mixture ...
