construction waste resource utilization - eastman rock crusher

Construction waste refers to the solid waste generated during the construction, maintenance, and demolition of buildings, including waste concrete blocks, asphalt concrete blocks, mortar, broken bricks, metals, bamboo wood, waste materials from decoration, and various packaging Materials and other wastes, etc., account for about 30%-40% of the total amount of municipal waste, which is a source of larger municipal waste.

Most of the construction waste is directly piled up in the open or landfilled without any treatment. This treatment method not only takes up a lot of valuable land resources, but also wastes a lot of recyclable building materials, and also increases environmental pollution.

The resource utilization of construction waste is in line with the policy of developing a circular economy and sustainable development. The resource utilization of construction waste is handled well, and while obtaining environmental benefits, it also has good economic benefits. Construction waste recycled products, including recycled aggregates, recycled inorganic mixtures, recycled bricks, recycled concrete, etc., can be widely used in various road projects, municipal administration, gardens, river slope protection, squares and other fields.

The objects of the crushing operation are mainly concrete materials and stone, the purpose is to reduce the particle size, increase the uniformity of the shape, and facilitate the subsequent processing procedures. When the crushed construction waste is subjected to separation treatment such as screening, winnowing, and magnetic separation, due to its uniform particle size and increased fluidity, the separation efficiency and quality can be greatly improved, and it is conducive to high-density landfill treatment and saving space.

Through sorting, the useful ones are fully selected and used, and the harmful ones are fully separated, especially the construction waste is divided into different granularity levels for different recycling processes. According to different properties, sorting includes manual sorting, screening, gravity sorting, magnetic sorting, buoyancy sorting, optical sorting, etc.

Screening is the use of a sieve to pass the fine material smaller than the sieve hole through the screen surface, while the coarse material larger than the sieve hole remains on the screen surface to complete the process of separating coarse and fine materials.

Mobile crushing equipment is used to process the construction waste on site, reducing transportation costs and avoiding secondary pollution. Various mobile equipment can be combined with each other as required to produce various recycled aggregates.

Construction waste is the muck, waste metal, crushed stone, waste mortar, bricks and tiles generated during the construction, paving or demolition and repair of various buildings, structures, pipe networks, roads, etc. . According to statistics, the annual output of construction waste in 2014 reached 1.5 billion tons. For every new 10,000 m2 building, 400-600 tons of construction waste are produced; for every 10,000 m2 old building is demolished, 5000-7000 tons of construction waste are produced. The construction waste made us suffer from the garbage siege while enjoying civilization.

Environmental benefits: Utilize modern equipment to treat construction waste nearby to realize recycling instead of traditional construction waste disposal methods such as accumulation and landfill, and reduce pollution to land and rivers.Economic benefits: The construction waste processed by the mobile crusher can generate recycled aggregates, recycled concrete and various recycled bricks, so as to realize the resource utilization of construction waste.

The mobile construction waste crushing plant is mainly composed of feeder + jaw crusher + impact crusher/cone crusher + sand making machine + vibrating screen and other equipment.The mobile crusher plant is universal, economical, practical, flexible, and integrated. Fully automatic crushing, conveying, screening, and iron removal.
