Nickel-iron slag vertical mill grinding equipment prices

1. produce nickel-iron slag

Nickel-iron laterite nickel ore slag is generated in the smelting of nickel-iron or nickel refining process industrial waste. In recent years, with the rapid development of China's stainless steel and special steel industry, smelting nickel-iron gradually expand the scale, emissions of nickel-iron residue is also increasing year by year. According to statistics, in 2015 the whole year nickel-iron slag has more than one hundred million tons.

2. Nickel-iron slag treatment

At present, China nickel-iron slag comprehensive utilization rate is low, its approach is more open stockpiles or landfill, this is not only a waste of resources, take up a lot of land, and destroy the surrounding environment, seriously restricting the sustainable development of nickel-iron industry . Realized nickel-iron slag in the field of building materials large-scale resource utilization is an effective means to improve the utilization of nickel-iron slag. With the resources and energy have been put forward as well as the growing shortage of relevant national policies, comprehensive utilization of nickel-iron slag increasing attention has been paid.

3. The nickel-iron slag as a cement admixture to be an effective way to use

Nickel-iron slag cement admixture application has been made more valuable research results. Studies have shown that nickel-iron slag with ash activity, nickel-iron slag slag finely ground to powder, can be added to the cement clinker in cement admixture. The use of nickel-iron slag cement admixture preparation, the addition of up to 30%. Industry experts made many research experiments, the results show that the nickel-iron slag and steel slag, slag and other industrial waste, as can the production of cement clinker, and the nickel slag has a very good activity, slightly better than the steel slag.

4. The use of nickel-iron slag grinding faces the greatest challenges

Nickel-iron slag grindability difference is the main reason leading to low utilization. nickel-iron slag containing silicates, aluminosilicate minerals such as it has the potential cementitious activity, but because of the nickel-iron slag compact structure, high crystallinity and containing certain minerals iron minerals, making it relatively easy to grind poor, seriously restricting the utilization of nickel-iron slag. Nickel iron slag grinding process optimization through innovative technology and equipment to improve the activity of nickel-iron slag, nickel-iron slag important way to promote the field of building materials widely used.

5. Nickel-iron slag grinding process Introduction

For nickel-iron slag grindability problem of poor, CHAENG launched a national patent legislation GRMS Nickel slag mill, the nickel slag vertical mill not only adapt to the high hardness materials, and greatly improve grinding efficiency and reduce power consumption grinding, grinding noise and investment in civil engineering, production of nickel slag specific surface area of 450㎡ / kg or more, and 28 days to reach maximum activity of play, can be completely suitable as a cement admixture, concrete.
