What kind of machine is suitable for grinding coal gangue into powder? This is a widely concerned issue for customers who want to recycle and reuse coal gangue. Coal gangue is one of the common industrial solid waste, with a large storage capacity, which urgently needs to expand the scope of reuse. Grinding coal gangue into powder has become a powerful way. Therefore, what kind of coal gangue grinding mill is used for grinding coal gangue into powder?
Let’s first introduce what coal gangue is and how it is produced? Coal gangue is a solid waste generated during the mining and washing processes of coal mines. It is a black gray rock with lower carbon content and harder hardness than coal that is associated with coal seams during the coal formation process. Some places are also called gangue. The emission of coal gangue is increasing year by year with the development of the coal mining industry, as the accumulation is too large and the consumption cannot keep up, becoming an environmental problem.
Many customers and friends may be curious to hear that coal gangue can produce kaolin. What is this? Firstly, we need to clarify that not all coal gangue can be used to produce kaolin. Here, it is necessary to look at the composition of coal gangue. The most important point is that the aluminum content of coal gangue is much higher than the silicon content, and the aluminum silicon ratio is greater than 0.5. High alumina coal gangue is the main raw material for producing coal based kaolin, which can be produced through the process of calcination and grinding. The grinding process is indispensable in the production process.
What kind of machine is used to grind coal gangue as a raw material for kaolin into powder? If the production capacity is required to exceed 20 tons per hour, it is recommended to use a vertical grinder for processing. Taishi has a large output, high efficiency, and can achieve large-scale processing. It is also easy to maintain and has low comprehensive investment costs. HCMilling(Guilin Hongcheng)’s HLM series coal gangue vertical grinding mill has been successfully applied in coal gangue pulverization projects.
Except for a small portion of the raw materials used for coal based kaolin, most of the remaining coal gangue can only exist as solid waste. How can coal gangue from solid waste be utilized? If it is coal gangue with high calorific value, it can be used to produce combustion aids, coal pellets, etc. Some can be directly calcined, while others need to be ground first and then kneaded into pellets. In addition, coal gangue can also be used as a building material to produce some unburned bricks, blocks, composite cement, etc. What kind of coal gangue grinding mill is used to grind this type of coal gangue into powder? Generally, it only needs to be ground to 200 mesh. Considering the scale and cost investment, it is recommended to use coal gangue Raymond mill as a suitable method. The hourly production is approximately 1 to 20 tons, with a small footprint, stable performance, and good environmental protection effect.
What kind of coal gangue grinding mill is used to grind coal gangue into powder? The above recommendations have been made based on the different applications of coal gangue. Of course, further detailed communication is needed to understand more about the coal gangue vertical mill and the coal gangue Raymond mill, as well as the latest equipment quotations.
