With the development of our country's economy and the acceleration of urbanization, the production of construction waste is rising year by year. In the past, the garbage disposal in our country is extensive, and construction waste is often landfill treatment or dumped in chaos. But at present, the production of construction waste in our country is huge, data show that the annual production of urban construction waste in our country exceeds 2 billion tons, accounting for about 40% of the total municipal solid waste. Such a huge amount of production will harm the environment and waste resources if it is treated extensively, so the national policy also strongly recommends the resource treatment of construction waste.So how is construction waste recycled? Construction waste is mainly composed of abandoned concrete blocks, masonry debris, etc., if the construction waste is treated as resources, it can be turned into treasure, the waste is made into aggregate or recycled bricks, which not only solves the

With the rapid development of the city, the expansion of the urban area, the acceleration of the transformation of the old urban area, and the sharp increase in the amount of construction waste have seriously hindered the pace of urban development. The matched construction waste disposal industry has also flourished. Fixed construction waste disposal production lines can be built where construction waste can be continuously collected, while mobile and flexible crushing and sorting equipment can be selected in areas where construction waste is relatively scattered. Then some people will ask, is tire type mobile crushing station better or crawler type mobile crushing station better? We can analyze from the following three aspects:First, from the perspective of investment cost, the tire type is slightly lower than the crawler type, because in terms of manufacturing cost, the tire type process is relatively simple, while the crawler type process is complex, so if the capital is sufficient, the crawler type is a
