Nickel slag recycling and reuse of steel slag, water residue and other industrial waste is another new industry, Chaeng(Xinxiang Great Wall Machinery) GRMS series of slag vertical mill in the nickel slag grinding recycling plays a significant role.in the current,Chaeng has the energy to complete an annual output of 30 to 100 million tons nickel slag production line matching, production efficiency gratifying. Today, Chaeng will explain to customers about how to recycle nickel slag.

First, the introduction of nickel slag

Nickel slag is the smelting of nickel-iron alloy produced solid waste, nickel-iron alloy is mainly used for the production of stainless steel, nickel slag is also known as stainless steel slag or nickel iron slag.

Due to nickel-iron smelting technology, the nickel slag contains a certain amount of nickel-iron alloy, nickel-iron alloy prices vary according to the nickel content of different levels, many customers are looking for from the stainless steel slag in the recovery of nickel-iron alloy Industry, hope to obtain considerable economic benefits. Therefore, the use of the latest vertical mill grinding machine grinding technology, and after a lot of experiments and cases, to better fine grinding of nickel slag into the fineness of the product, to achieve an independent design and manufacture an annual output of 300,000 tons to 100 Million tons of nickel slag production line project equipment.

Second, the role of nickel slag grinding

High nickel slag recycling can not only reduce the waste of resources and environmental pollution, but also produced a considerable economic benefits.

The use of wet fly ash, nickel slag instead of clay, iron ore ingredients in the modernization of the kiln production of clinker, in the raw material grinding through the adoption of appropriate technical measures and changes in raw materials to solve the large-scale unloading drying Grinding, the grinding of silica is difficult to grind, the particle size of materials, fly ash and high moisture content of the material mill, the quality of the problem; in the clinker calcination to overcome the refractory material, firing temperature and raw materials containing unburned The use of coal ash, nickel slag, cement grinding capacity has been improved; mixed with more than two kinds of industrial waste slag, enhanced the admixture of concrete admixture sex

Third, nickel slag treatment

So that the discharge of slag in the process of comprehensive utilization of nickel or do not pollute the environment process. According to the production process of nickel, nickel slag can be divided into nickel pyrometallurgical slag and nickel wet smelting slag two.

Nickel pyrometallurgical slag is a molten slag produced during the high-temperature melting of nickel and is naturally cooled to form a solid or solid product by forced cooling. The finely pulverized nickel smelting slag is mixed with water glass to produce high strength, water and sulfate resistant cementitious materials. The water quenched nickel slag can be used to make bricks and make refractory (800 ℃) concrete.

Nickel hydrometallurgical slag is a solid residue resulting from the chemical leaching of nickel from nickel ores. Muddy. A small number of nickel hydrometallurgical slag containing iron up to 66%, can be used as iron raw materials. But most of them have not been utilized, but are disposed of by dumping, landfilling or solidification.

4, nickel slag production line configuration and case

2010, Chaeng first saw the slag/steel slag/nickel slag recycling market value and prospects, so the use of self-produced slag vertical mill/nickel slag vertical mill as the main system, the construction of the first year of the domestic Production capacity of 600,000 tons of slag powder/nickel slag production line, strong production capacity and market sales, in less than three years time, Chaeng recover the investment costs, is currently in net income state.

The state has repeatedly stressed that environmental protection, low-cost production of the regulations to bring a lot of pressure on industrial enterprises, and at this time, the common slag material through vertical mill grinding process can be applied to the cement admixture in the cycle of development So that they see a bright future, so many steel mills, coal plant customers have to Xinxiang Great Wall Machinery to visit the slag/nickel slag production line, its recognition and satisfaction greatly increased, so in 2013, the annual output of 30 , 60,90 million tons of nickel ore slag/total turnkey project contract successfully signed, this result indicates that the Chaeng has been strong among the well-known "grinding system integration provider" ranks, to achieve from manufacturing to Service transformation and upgrading, with a vertical mill overtaking the target bend has been basically achieved.

Chaeng is a professional manufacturer of grinding equipment, the Company of high nickel slag, low nickel slag, stainless steel slag, chromium iron slag, silicon manganese slag and other solid smelting waste recycling with unique insights and practical experience, free of charge Customers and design of small-scale recycling process design and equipment configuration, we are welcome customers to visit our factory, we wholeheartedly at your service!
