Production equipment for high-quality asphalt mixture and production method thereof

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 ...

AI Technical Summary

Problems solved by technology

Due to the limitation of traditional asphalt mixture screening equipment, the current existing asphalt mixture production equipment, most of the finest material classification is only 3mm, and the fine aggregate cannot be subdivided in the next step

However, in the case of very high-performance asphalt asphalt mixtures (such as pouring asphalt), due to the importance of the gradation of fine aggregates, further subdivision is required. The usual gradation is: 2.36mm, 1.18mm, 0.6mm, 0.3mm And 0.15mm, which cannot be realized on the traditional asphalt mixing equipment
