recycled aggregate quality and crusher
Tackling the quality issue in aggregates recycling
“Traditionally, demolition recycling might only have produced crusher run 6F2 and 6F5 aggregates,” says Dolman “We are able to make highgrade, clean and singlesize end products such as sand, 10mm clean, 20mm clean and certified materials for use in construction products”The crusher is the core component of the mobile crushing plant, which is mainly responsible for crushing construction waste To ensure the performance of recycled aggregate, it is necessary to ensure that the particle size distribution of the crushed material should be uniform, so the crushing capacity, crushing efficiency and material qualityMobile Crushing Plant For Recycled Aggregate | M&C
