Annual production and processing of a large variety of metal ore materials, in the process of production will also produce a variety of industrial solid waste, such as blast furnace slag and nickel slag production line in iron furnace; non-ferrous metal smelting of various non-ferrous metal slag, such as copper slag Lead slag, zinc slag, nickel slag, etc. These industrial solid wastes not only occupy the land, but also pollute the environment. Therefore, how to effectively solve these solid wastes has become a major problem in the industry.

Nickel slag is a kind of solid waste generated during the metal nickel and nickel alloy smelting process. To solve this problem, it is very necessary to build a whole nickel slag production line. First of all, for the enterprise, the recycling of nickel slag can not only reduce the waste of resources and pollution of the environment, but also produce considerable economic benefits.

To build a nickel slag production line, Xinxiang Great Wall has mature cases for customers' reference. For example, Xinxiang Great Wall was a nickel slag production line built by Xuchang Company in 2012. At that time, there were only a few domestic nickel slag production lines, and the nickel slag powder produced by the production line. The slag powder was sold to Henan Tianrui Cement Co., Ltd., the largest cement company in the province, and was used in the large-scale infrastructure projects such as the South-to-North Water Transfer Project and the Shiwu High-speed Railway. Good economic returns and sales are very hot.

At the end of 2013, the company signed a second nickel slag production line contract with Great Wall Machinery. The project was officially launched in March 2014. On August 12, 2014, the second nickel slag powder production line was successfully commissioned and reached the standard. The whole project was less than five months from start-up to commissioning. The construction speed was fast, the construction quality was high, the service was thoughtful, and the technology was excellent. The customer's high evaluation.

The nickel slag production line put into operation by the Xinxiang City Great Wall Machinery Co., Ltd. uses the vertical mill main engine produced by the Great Wall as the main system. After the nickel slag production line is put into production, the investment cost is fully recovered in less than three years. Pure profit status.
