Nickel slag is a solid waste slag produced by smelting nickel-iron alloys. Nickel slag is divided into different types such as dry slag, water slag, high nickel slag, and low nickel slag. Dry iron slag contains higher nickel-iron alloys, while water slag contains lower nickel-iron alloys. High nickel slags have higher nickel content and almost no magnetism. The nickel-iron alloy in the low nickel slag has a low nickel content and a high magnetic permeability. A large amount of nickel slag is stacked, which poses a high risk of potential pollution to the soil and groundwater environment. According to relevant data, the annual output of nickel slag in our country is about 4 million tons, and the utilization rate is only 10%. Therefore, the reasonable and effective use of nickel slag, turning it into waste, and reducing environmental pollution is the primary problem in industry.
The SBM heavy-duty nickel slag [url=https://www.smilehotelsuriname.com/product/vertical-roller-mill.html]vertical roller mill[/url] is built with leading domestic and foreign technologies. It integrates technology, innovation, quality and environmental protection. It is designed based on the use and suggestions of users of grinding mills and the guidance of domestic vertical roller mill experts. The new type of pulverizer is stable in operation and the quality of the finished product is good. It is suitable for grinding and processing of mineral materials such as metallurgy, building materials, chemicals, mines and so on. As a well-known comprehensive service provider of grinding systems in China, SBM Heavy Machinery continuously breaks through innovation, overcomes the problems of grinding machines, finds problems in development, solves problems technically, and becomes a vertical roller mill manufacturer trusted by users!
SBM heavy machine vertical roller mill technology is widely used in industrial solid waste treatment, not only can handle nickel slag, but also can be applied to the more difficult to handle slag, coal, gypsum and other mineral products. With the continuous development of science and technology, China's powder industry technology is also constantly innovated. The use of foreign advanced technology in technology has made the mill into various industries, and then promoted the development of China's powder industry technology. Introduction to the working principle of nickel slag [url=https://www.miningcrushersale.com/product/grinding-mill/lum-vertical-roller-mill.html]vertical roller mill[/url]:
The material discharge tube falls to the center of the grinding disc. The grinding disc that rotates at a constant speed uses the centrifugal force to evenly spread and spread the raw materials outward to form a material bed of a certain thickness. The material is simultaneously crushed by multiple grinding rollers on the grinding disc. Crushed and crushed. Under the continuous driving of centrifugal force, the material continuously moves towards the outer edge of the grinding disc. When the material leaving the grinding disc encounters the hot gas entering the mill through the air ring and rises with it, it enters the separator through the middle casing of the mill. In this process The medium material and the hot gas have undergone sufficient heat exchange, and the water is quickly evaporated. The classifier controls the fineness of the finished product at the exit of the roller mill. Particles larger than the specified size are separated and fall back to the grinding disc. The materials that meet the fineness requirements enter the finished product bin through the sorting machine. After the finished product is collected, it is transported into the finished product bulk warehouse, and the exhaust gas is discharged after being silenced by the fan. Partially difficult-to-grind large-grain materials enter the external circulation system through the slag discharge port at the wind ring, and after being removed from the iron, they are fed into the mill by the elevator again for grinding.
