The production technology of the wind turbine generators’ blades comes from abroad. Chinese manufacturers haven’t grasped many core technologies adopted during the process of the blades’ pilot development, design and manufacturing, as well as the production of mining devices and equipment. In addition, enterprises overseas have gone down to make further research and development on new issues including how to increase the utilization of wind energy and how to extend products’ service life effectively.
There are many reasons that cause the following problems faced by domestic industries:
1. The production standard of making blades of spiral separators formulated by the government standard committee is still in the process of drawing without receiving the recognition of several foreign nations.
2. The domestic scientific research institution is unable to meet the increasing demand of manufacturers.
3. Most enterprises, research institutions and industrial departments are too eager to gain success, and they are not willing to be dedicated to the long term and hard basic research, so they don’t have enough capability to undertake the huge risk.
4. The poor developing situation of the domestic basic industry still exists.
Only by overcoming the above problems can Chinese spiral separator manufactures win a large piece of share in the global market. In recent years, the manufacturing of spiral separator has made much progress in the mining machinery industry and will form a large industry scale in the future. The technology and raw materials China’s manufacturing enterprise are mostly introduced from the foreign countries, and the disadvantage of the domestic spiral separators is the excess production capacity of low-end products, namely lacking competitive high-end products.
