How to solve the pollution of nickel slag on land and environment?

Nickel exists in the form of nickel silicate or sulfur, arsenic and nickel compounds in nature, and its applications range from civilian products to aerospace, missiles, construction and other industries. Nickel slag is an industrial waste discharged from the process of smelting metal nickel.

The non-ferrous metal nickel smelting slag has a large discharge and has a high potential for soil and environmental pollution, so it needs to be comprehensively utilized. At present, the commonly used method in the industry is to process nickel slag into nickel slag powder through a new high-efficiency vertical mill. After the grinding, the waste slag can be sold to cement plants or new building materials plants as additives for new building materials, and made into new building materials. The process basically realizes the complete recycling of nickel-iron alloy slag, reduces the waste of useful resources and harm to the environment, realizes the complete recycling of waste materials, and truly achieves "no waste, no tailings, no pollution".

Ultra-fine GRMS nickel slag vertical mill is an ideal equipment for grinding nickel-iron slag. It has the functions of grinding, drying and powder sorting. After long-term practice, Xinxiang Great Wall has a power consumption of less than 43 kWh/t for the nickel slag vertical mill system, which is 30%~40% less than the traditional ball mill. The grinding efficiency is high, which can reduce the production cost of the enterprise, consume energy low and environmentally friendly.

CHAENG has already built nickel slag production lines twice, all of which use GRMS nickel slag vertical mills. The operation is stable and the finished products are of good quality, which has won high praise from customers. Customers investing in the construction of nickel slag production line can, on the one hand, bring profits to enterprises, on the other hand, recycle nickel slag, reduce resource waste and environmental pollution, and contribute to society.
