Production of natural and recycled aggregates: the ...

Jun 22, 2017  高达10%返现  Today, as mentioned before, aggregate production and recycling are defined in the form of crushing and in the central and the mobile plant types. In this research, with regard to the large-scale proposed recycling plan for Iran, only is the central type (fixed) considered. NA production (the first scenario) consists of three stages.

About this site

Inert wastes suitable for producing recycled aggregate should be stored separately from mixed wastes and in a manner which prevents cross-contamination. Non-inert waste from household, commercial and industrial sources such as trommel fines produced from mixed waste is not permitted to be used in the manufacture of recycled aggregates.

Jul 29, 2016  Then, the optimum abrasion conditions for the production of recycled fine aggregates were derived using the response surface methodology (RSM). During the optimization procedure, unit production amount was expressed as a function of coarse aggregate ratio and the abrasion time and was taken as the objective function.

Recycled Aggregate - California

Recycled aggregate comes primarily from PCC and AC from road rehabilitation and maintenance, demolition, and leftover batches of AC and PCC. After processing, the rocks retain bits of cement or asphalt. A roadway is built in several layers: pavement, base, and sometimes subbase. The pavement is the surface layer, and is made of PCC or AC.
