crusher is widely used for disposing construction waste
Crusher is also called stone crusher, which is widely used in many fields, crushing construction waste is no exception. Crushing construction waster, on the one hand, should consider from the aspect of urban environmental protection, and conform to the regulation of national urban construction waster disposing, all of which requires the usage of crush itself should have property of environmental protection, so as to reduce noise in process of production, reduce dust, and rationally solve many polluting factors; on the other hand, urbanization process is still speeding up, clamor for recycling utilization of construction waste seems increasingly strong, processing capacity for construction waste crushing is also a hard index of test. Production capacity of crusher is also another important aspect that need to be improved.
Construction waste requires to sorting, many litter in construction waster can be re-used as renewable resources through sorting, discarding, or crushing. As for the more severe urban construction waste problem, many success methods of developed countries can fully provide us with the guide and basis. After being crushed by crusher, brick, stone, concrete, and other waste material can replace sand to be used for masonry mortar, cenel-luder, making cushion of concrete, also can be used for making construction material, such as building block, road brick, lattice brick, and color brick, etc.

According to present features of construction waste, recovery and utilization rate of construction waste is up to above 95%. Let take using construction waste to make regeneration brick, compared with clay bricks in aspect of energy-saving and environmental protection, produces for 150 billion standard bricks, crusher can reduce borrow earth for 240 thousand cubic meter, dispose construction waste more than 400 thousand ton, saving land for 340 mu. Besides, in the process of making bricks, fly ash can be disposed of 40 thousand ton, saving standard coal for 15000 ton, reduce sulfur dioxide discharged by baking bricks for 360 ton. Therefore, crushing treatment for construction waste is a industry which has brilliant prospect.
If it continues to grow at this rate, estimating according to the newly produced construction waste by 2020 for 500 billion ton, if all the construction waster can be processed by crushing and converted to ecological building material, the value that created by them will be up to 10 billion. However, there are fewer enterprises that engage in crushing construction waste and reutilization in the worldwide, national reproduced utilization rate is only around 5%. With gradually attention to environmental construction paid by government offices, dispose of construction waster will soon meet more powerful support of national policies and broad market space.
