Abstract: with the accelerating urbanization process, urban transformation and the rapid development of construction industry, concrete as cement, sand, pebbles and gravel, the biggest consumers of natural resources, global concrete industry is now at an annual rate of about 8 billion tons of consumption of natural aggregate. At the same time, some old buildings, structures, the ageing of the urban infrastructure and service term expires, making more and more civil engineering construction project scrap, and produce a large number of building demolition waste and rubbish. Aggregate process Plant development is imminent.

Aggregate Recycling Plant

Aggregate Recycling Plant refers to the different crushing equipment, screening equipment, transmission equipment and equipment reasonably to remove impurities together, to build, repair and waste produced during the demolition of buildings, including sand and gravel, brick, concrete block, scrap wood, glass, asbestos, confetti, fiber flock to recycle, waste plastics, metals and other production into Aggregate, used to fill the void of natural Aggregate now. Recyclinging method of the quality of the Aggregate and the Aggregate Recycling Plant is close, so the production Recycling needs a set of economy applicable sorting, crushing, screening, clean technology Recyclinging methods, Recyclinging should be through the system planning, and selection of high quality Recyclinging equipment. Construction waste Recyclinging, the basic hardware requirements including bridge crane (rubble and aggregate output), storage space (storage of different types of aggregate and recycled product), pretreatment equipment (vibration hammer, etc, used for crushing large waste), loading and unloading equipment, packing and loading), preliminary screening plant (in front of the broken to remove soil, gypsum, sand and other impurities), preliminary crusher (jaw crusher), electromagnetic system (iron) was isolated from the rubble, screening equipment (used for separation of smaller particle size of aggregate), secondary crushing and screening equipment, respectively to break aggregate into required size and divided into different parts). Concrete Aggregate Recycling Plant Recycling, you can consult our experts, they will be for your detailed explanation and flow chart will be explained in detail to you.

Status Quo of Aggregate Recycling Plant

Aggregate Recycling Plant can put the construction waste Recyclinging production as the weight Aggregate concrete used for building structures (such as block), road surface and cement production, etc. The current situation of the development of the countries in the world today Aggregate Recycling Plant is different, the utilization of developed countries is higher, utilization rate is low or no use in developing countries. Illinois construction materials recycling committee William Turley, according to a report every year one hundred million tons of waste concrete is in the form of recycled aggregates have been recycled, accounting for 5% of the total aggregate volume (the aggregate total amount of more than 2 billion tons per year). About 68% recycled aggregates are used for road base and foundation, 6% is used for mixing the new concrete, asphalt concrete, and the 9% to 3% for slope protection, 7% for general backfilling, other applications 7%. Better country belongs to the Aggregate Recycling Plant development.

Problems Faced by the Aggregate Recycling Plant

From energy saving, environmental protection and sustainable development into consideration, such as Aggregate process Plant development is imperative. To fully implement Aggregate process Plant, must be good to solve the following questions: (1) to strengthen the scientific research of construction waste Recycling. Aggregate process Plant mainly in the form of recycled aggregates. The strength of the recycled aggregates, apparent density and bulk density, water absorption and crush index, elastic modulus of aggregate, content of impurities and so on directly affect the impact on physical and mechanical properties of recycled concrete. (2) to establish the corresponding supporting policies, technical specifications and technical standards. Such as government formulated some special regulations of the “mandatory” and “encouraging”, study and encourage the construction of Recycling and utilization of waste policy, regulations and industry standards, from the industrial policies and regulations to guide Aggregate process; Strengthening process Aggregate economy analysis as building material, research for improvement of the economy; Making Aggregate process of relevant codes and standards. (3) strengthen the sustainable development of energy saving, environmental protection propaganda, change the Aggregate process of traditional attitudes.
