Construction Waste Crusher

Construction waste is mostly solid waste, usually in the process of construction or old building maintenance and demolition process. The content of various waste components produced by different types of buildings are different, but the basic form is the same, mainly by soil, soil residue, scattered mortar and concrete, chiseling the masonry and concrete pieces, piling cut reinforced concrete pile head, metal, bamboo and wood decoration the waste, all kinds of packaging materials and other wastes.

Background of construction waste disposal

With the development of urban construction, a large number of building materials consumption intensifies the consumption of mining and transportation energy. China’s per capita mineral resources are only half of the world average, and the per capita possession of land and cultivated land is 1/4 of the world average. In the concrete case, in recent years Shenyang area of commercial concrete production multiplied, 10 million m3 in 2010 to 2011 reached 12 million m3, and the corresponding amount of cement sand reached 5 million tons, 7 million 500 thousand M3, 10 million 500 thousand M3 stone. Considering from the perspective of circular economy, the construction waste brick, stone, concrete block (accounting for more than 90% of construction waste) resource utilization, directly to the construction waste crushing for recycled coarse and fine aggregate instead of natural aggregate, or groups in the characteristics of the use of construction waste to produce new building materials products. Resource utilization of construction waste is an important measure to solve the problems of high energy consumption, high pollution, high emission and low efficiency, is an important way of saving land, saving resources, is an important measure for the development of circular economy, the construction of environment-friendly and resource-saving society, is the inevitable requirement to implement the Scientific Outlook on Development, to achieve sustainable development and protect the environment. That is the only way which must be passed to achieve the sustainable development of the city.

The construction waste is not helpless, and if it is effectively handled, it can be used as renewable resources, and bring significant economic and environmental benefits. Construction waste treatment equipment in the research and development of SBM is a new type of crushing and screening equipment, feeding, conveying and crushing process as a whole, is more advanced in today’s world of a crusher, can the construction waste processed into recycled concrete aggregate of new wall materials, raw materials, accessories and other fill Road base. The utilization rate of up to 98% above the construction waste recycling.

Construction waste solution

Comprehensive recovery and utilization of SBM for the development of the mobile construction waste crushing station, integrated feeder, crusher, vibrating screen and other equipment to set the crushing and screening system as a whole, the recycling of construction waste is preferred.

According to the particularity and the limit condition of the construction waste disposal unit, the company has developed two kinds of mobile crushing stations, caterpillar type and tire type, respectively, and the production capacity can reach 100~300 tons / hour.

Tire type mobile crushing station can be configured and running system of heavy truck axle, small volume, light weight and easy traction on the road, split, folding parts, convenient transitions, convenient installation, shorten the construction period.

Application device of Construction waste crusher

The mobile crushing station is set in mobile by one or several tractor trailers on the raw material warehouse, vibration feeder, crushing equipment, multi-layer vibrating screen, crushing equipment, crushing equipment, portable belt conveyor, sand washing machine, electric control system etc. the crushing and screening line, mainly used for highway and railway, metallurgy, chemical, building materials and other industries need to keep moving, the relocation of the crushing operation.

Value of construction waste recycling

economic value:1,Brick, stone, concrete and other waste materials after crushing, can replace sand, used in masonry mortar, plastering mortar, concrete cushion; waste concrete block material after pulverization can cooperate with standard sand as fine aggregate mortar mix for the wall surface plastering, roof screed, masonry mortar, floor brick making etc..;2,The waste brick is crushed and used to aggregate the building board. The partition board is not only light in quality, high in strength, but also sound proof and has small coefficient of expansion, which greatly reduces the cost of sheet material because of its easy and cheap material.;3,The crushed concrete block can be used as cast in place concrete or prefabricated aggregate, and used for non load bearing parts of the building. This not only saves construction funds, but also does not reduce the strength of structures. It can be seen that the construction waste can be recycled and utilized to produce certain economic benefits.

Environmental value:Environmental protection is a major problem in modern industry, especially in modern countries. It is one of the most important goals of environmental protection in the world to make the waste of city construction reuse and reuse. At present, China is in a period of rapid economic development, and the construction site waste emissions are large. According to the survey, China’s construction of the construction waste every year up to million tons, most of them without any treatment, some piled up in the open air, some low-lying areas in the landfill, causing environmental pollution and waste of resources, comprehensive utilization of construction waste is reasonable use of these resources, obtains the certain economic efficiency. And improve the environment, beautify the city, largely to avoid the construction waste disposal, the release of harmful gases to city residents health hazards.
