• Solving the heating problem of plant mixed asphalt heat recovery technology 2023-09-04

  Heating issues The heating problem of recycled materials is the primary issue that asphalt thermal regeneration technology needs to face. Whether it is plant mixed regeneration or on-site regeneration, it is necessary to heat the recycled materials. The heating temperature of recycled materials, the selection of heating methods, and the rationality of heating structures will have a significant impact on the stability of finished materials, the reliability of equipment operation, and the continuity of later stages. The heating of recycled materials plays a connecting role in the regeneration technology of plant mixed asphalt. As the saying goes, 'A small mistake travels a thousand miles'. Therefore, to a certain extent, the success or failure of plant mixed asphalt thermal regeneration technology depends on whether the heating is appropriate. Key issues The bonding problem of recycled materials is a derivative issue of plant mixed asphalt heat recovery technology. From the moment the temperature of the recycled material rises, the bonding problem restricts the entire production process. Whether it's in drying drums, temporary storage units, recycled material metering units, chutes, etc., bonding issues are ubiquitous. Bonding is not only related to the inherent physical properties of asphalt recycled materials, but also closely related to their heating temperature. After repeated heating, the mechanism and chemical composition of asphalt have changed, coupled with dust pollution from the mixing plant, its bonding performance is even more outstanding. Solving the bonding problem of waste asphalt materials can help improve the overall level of the factory's mixed asphalt heat recovery process. Asphalt smoke and dust treatment issues Asphalt smoking is a manifestation of the chemical properties of waste recycled materials after heating, and heating temperature is the main factor affecting the chemical composition of asphalt smoking.
