What is the Development Prospect of Mobile Crusher?
News related to the mobile crushing station of construction waste and solid waste concrete processing equipment occupies the major mainstream media news sections.
The Status of Chinese Construction Waste Disposal
Construction waste is produced during the construction, maintenance and demolition of buildings. It includes waste concrete blocks, asphalt concrete blocks, mortar, crushed brick slag, and other wastes. It is a large municipal waste source.
Most of China's construction waste is directly stacked or landfilled without any treatment. This kind of treatment not only occupies a lot of valuable land resources, but also wastes many shortages of building materials that can be recycled, and at the same time, problems such as throwing, scattering, dripping, leaking and dust, flying sand and flying in the process of clearing and stacking, It has also increased environmental pollution.
The classification of construction waste solid waste concrete is based on the economics of waste concrete recycling and the performance requirements of recycled aggregate. Solid waste concrete can be divided into two categories, one is recyclable solid waste concrete and the other is non-recyclable solid.
Whether the waste concrete can be recycled can be determined according to the source, the use environment, the exposure conditions, etc. It is recommended that the following waste concrete should not be recycled:
(1) Concrete from special use requirements (such as nuclear power plants, hospital radiation rooms, etc.)
(2) Waste concrete contaminated with heavy metals or organic matter;
(3) Waste concrete with alkali-aggregate reaction;
(4) Waste concrete containing a large amount of wood chips, sludge, asphalt, etc. that are difficult to separate.
Process and equipment for utilization of construction waste resources
At present, the application of a wide range of construction waste resources mainly includes in-situ crushing and regeneration and plant crushing and recycling.
1. In-situ crushing and recycling process and equipment - mobile crusher
Most of the in-situ regeneration process is carried out at the construction waste site using mobile crushing equipment. The advantage of this method is that various devices can be moved to the processing point arbitrarily, reducing transportation costs and avoiding secondary pollution; various mobile devices can be combined to produce various recycled aggregates.
2. Factory crushing and recycling process and equipment - fixed crusher
The factory breaks the recycling process and uses fixed equipment to process construction waste at the factory. This method can build a large construction waste treatment production line, and produce it in a closed workshop to reduce various pollutions, and can produce various aggregates to achieve zero emissions. Stationary equipment includes crushing equipment and sorting equipment.
