The restructuring of the dryer machine industry is inevitable because the advantages of large-scale production are more and more obvious and it will promote the development of construction waste crusher in China. Large-sized construction waste crusher will have very wide application prospect in the future. When used in petrochemical industry and inorganic chemicals, construction waste crusher has high processing capacity, but some dryer machines can still not produced in China because of the backward technology. And the reasons of it are as follows: (1) The current production of construction waste crusher does not form real economy of scale which cannot effectively stimulate the research enthusiasm of the large-sized equipment. (2) The majority of large-sized equipment depends on import, as a result of which, domestically manufactured equipment is not able to effectively enter the market. Although there is plenty of construction waste crusher manufacturing plants in China, many of them are small and medium sized ones whose processing capacity cannot satisfy the needed production scale, but foreign dryer machines are developing towards large size. With the development of technology protective system in China, this disorderly competition will be gradually cancelled and Machinery believes that in the near future, the key to successful development of construction waste crusher is high content of science and technology.
