The steel industry is the main application field of iron ore powder. With the continuous growth of global and domestic steel demand, the mining and processing technology of iron ore powder continues to advance, promoting the development of the iron ore powder industry. The vertical roller mill plays an important role in the production process of metallurgical pellets! The Shanghai Zenith LM vertical roller mill can process iron ore (also known as iron ore vertical roller mill) in the production of steel smelting and block making technology. The mixture uses pellet materials such as limestone, dolomite, quicklime, bentonite, coke, anthracite, and steel slag, which are efficient and environmentally friendly.
Team Introduction——Ball ball mine
Ball production is a term used in the steel smelting industry. In order to ensure the uniform iron content in the iron ore of the blast furnace and the permeability of the blast furnace, the steel plant needs to make iron concentrate powder and various additives into 10-25mm block shaped raw materials. The main methods of block making include sintering and ball forming, which obtain sintered ore and ball forming ore respectively.
Introduction to ball forming process
There are two methods for smelting and making blocks: sintering method and pellet method. Simply understood, one method involves adding fuel to the mixture, while the other does not require the addition of fuel. So what are the two types of block making processes? What is their proportion in the steel smelting process?
Iron powder 200 mesh
1. Pellets: Iron concentrate powder 200 mesh D75 additive (limestone, quicklime, bentonite) - ingredients - mixing (adding about 9% water) - balling - roasting - screening - balling (pellets that do not pass screening are directly fed back for ball recycling, and some enterprises use column mills to process 0-3mm recycled balls) - blast furnace;
2. Sintering: Iron ore 0-10mm, solvent 3mm (quicklime, limestone), fuel 3mm (coke, anthracite), tailings (rolling mill skin, steel slag, blast furnace ash) and return ore (sintered ore tailings), dolomite - batching - mixing (adding about 9% water) - material distribution - roasting - sintered ore (10-25mm) - high furnace;
How does the Shanghai Zenith LM vertical roller mill realize its value in the production of pellet ore?
Due to the different methods of steelmaking and block making, different raw materials with different compositions need to be added. The processing of sintered ore and pellet raw materials is still different. Don't worry, Shanghai Zenith LM vertical roller mill can help you solve your worries:
1. Pellet ore raw materials
The raw materials for pellet ore include iron concentrate powder, limestone, quicklime, and bentonite. The raw materials for pellet mining can be produced using a zenith LM vertical mill. The LM vertical mill can produce 200 mesh D75 iron concentrate powder.
2. Sintered ore raw materials
The raw materials for sintered ore include iron ore powder, quicklime powder, limestone powder, coke powder, smokeless coal powder, steel slag powder, blast furnace ash, and dolomite powder. The production of sintered ore raw materials can also use LM vertical mills to achieve the fineness and corresponding surface area of the raw materials.
The Shanghai Zenith LM vertical mill has broad application prospects and development space in the metallurgical pellet iron ore powder industry of steel plants. However, enterprises also need to pay attention to challenges such as changes in market demand, technological upgrades, and environmental requirements, actively respond to and seek opportunities for cooperation and development.
