AI Technical Summary
Existing asphalt recycling material pretreatment devices suffer from problems such as insufficient cleaning power, scattered equipment layout leading to multiple material transfers and scattering and secondary pollution, unstable magnetic separation for small metal adsorption, poor connection between crushing and feeding causing easy overflow, and inconvenient treatment of waste cement residue.
A device comprising a soaking tank, a first conveyor, a crusher, a magnetic separator, and a second conveyor was designed. High-pressure atomized spraying is performed by a spraying mechanism, magnetic impurities are removed by the magnetic separator, and a collection box is provided for easy cleaning. The crusher and the magnetic separator are connected by a variable diameter square tube to enhance the continuity of the equipment and the cleaning effect.
It achieves efficient cleaning of recycled asphalt material, reduces the content of non-asphalt impurities, improves processing efficiency, and reduces equipment maintenance frequency and the risk of secondary pollution.
