When an asphalt pavement is used for a certain period of time, its load-bearing capacity will be greatly reduced. Therefore, this kind of asphalt pavement will be recycled through the participation of equipment. By adding some new materials and then reusing them, the cost can be greatly reduced. However, when recycling asphalt pavement materials, you must choose more advanced asphalt pavement recycling equipment to reflect high work efficiency and truly allow users to reduce investment costs.
The crushing and screening system of asphalt pavement recycling equipment includes a first-level crusher and a vibrating screen. It is mainly used to transport the output of the first-level crusher directly to the feeding belt conveyor above the vibrating screen, which can take over the end of the screen above the vibrating screen. After setting up and performing secondary crushing, the material discharged from the secondary crusher can be transported to the feeding belt conveyor. Through the return conveying device, the vibrating material is discharged and transported to the silo conveying device, and the material can be conveyed to the silo conveying device through the first stage of the equipment. Screen at different levels to obtain usable asphalt pavement paving materials.
Through asphalt pavement recycling equipment, the waste materials of asphalt pavement can be directly processed into diameters greater than 50mm, and then heated and dried during the process, because when laying asphalt pavement, the quality and diameter of the asphalt mixture product are If required, if the diameter is too large, crushing and screening are required to make full use of the asphalt pavement waste.
For example, when using old material particles in recycled asphalt mixtures, they should not be too large, otherwise it will be relatively difficult to incorporate the regenerant into the old materials. The reason is that the regeneration effect of the mixture will be affected. For example, under normal circumstances, the diameter of crushed old materials should be less than 25mm and not exceed 35mm. Methods for crushing asphalt pavement materials include manual crushing, but the work efficiency is very low. Mechanical crushing has high work efficiency and can be broken and heated to decompose in one go.
Today's old asphalt material crushing and recycling equipment has become more and more recognized by the market. Because our country's asphalt pavement area is relatively large and some waste asphalt pavement materials can be fully utilized, more advanced asphalt pavement recycling equipment is needed. Participation, as long as the equipment is advanced, the waste materials of the asphalt pavement can be re-screened to meet the material usage standards of the asphalt pavement. In addition, some new materials can be mixed in, which can greatly reduce the investment cost during recycling.
