Concrete - Business Recycling

The process of recycling concrete requires an initial breakdown of material using a primary jaw crusher, with further reduction carried out by cone crushers. The material is then screened and where required blended to produce a range of recycled products. These recycled materials are used in pavement construction, concrete production and
