In recent years, the southeast Asian countries accelerate industrial structure adjustment, infrastructure construction be in the ascendant, the industrialization, the urbanization process fast push, especially in Indonesia is flourishing demand for steel, this year is expected to more than 15 million tons, up nearly 10% on the previous year, and by 2025 the number will reach 26 million tons.

Growing metallurgical production must produce a large amount of industrial waste residue, and Indonesia Su Gang group as Indonesia region of mainstay role in metallurgical enterprises, the annual produce a large number of industrial waste residue, the experimental results show that if the industrial waste residue, deposited in the open air will produce serious occupation of land, soil pollution, pollution of water bodies and so on a series of social problems, so on industrial waste residue treatment be Su Gang fast developing urgently needed to solve a problem.

Through carrying out field visits on the multiple industrial waste residue to China grinding processing equipment enterprises, including domestic famous design institutes, but Indonesia Su Gang ultimately choose to cooperate with Xinxiang Great Wall , and successfully signed yearly produces 300,000 tons of nickel slag powder production line -turnkey project of the contract. The contract is the starting point of cooperation both sides, also is the Xinxiang Great Wall industrial slag grinding processing production line- turnkey project service to the world a new starting point.

Xinxiang Great Wall cooperation with the Indonesian Su Gang, on the one hand, is pushing by the national strategy of"One Belt and One Road" , China and Indonesia capacity cooperation presents gratifying situation, a certain extent also provide an important opportunity for Xinxiang Great Wall and Indonesia Su Gang group,on international waste slag recycling project cooperation smoothly ; On the other hand ,also with Xinxiang Great Wall in the field of industrial slag grinding treatment technology ability, management level, the accumulation of experience is inseparable.

By report,Nickel slag, this production line is expected in the second half of 2016 and put into operation, believe that the Chinese characteristic grinding equipment - vertical grinding machine equipment in Indonesia and even the entire southeast Asia is playing an increasingly important role in development.
