Coal washing machine is one of the commonly used coal testing equipment, and its presence can be seen in many places, especially in provinces with abundant coal resources such as Shandong and Shanxi. Sometimes people can see his figure nearby, and I believe many friends in big cities have not seen him before,

　　In order to improve the environment, many small coal mines have been integrated, but coal is still needed for winter heating. At least in the next decade, coal washing equipment can still generate waste heat.

　　Set up a coal bunker with a certain capacity near the coal mine entrance to receive coal raised to the ground underground, ensuring balanced and continuous production above and below the wellhead. The coal washing machine removes impurities from the raw coal or categorizes high-quality and low-quality coal. The finished coal after the coal washing process is usually called clean coal, which can reduce coal transportation costs and improve coal utilization. Clean coal is generally used as fuel energy, and the clean coal of bituminous coal is mainly used for coking. Generally, people refer to coal washing machines as jigs, and there are many types of coal washing machines, mainly including gangue extraction machines, raw coal discharge machines, multifunctional coal washing machines, and other equipment. The coal washing machine utilizes the principle of different densities, and then uses wind or water to stratify the coal seam, discharge poor coal quality, and obtain the most suitable clean coal.

　　When the coal washing machine is in operation, it is prohibited to use the method of scraping and rolling to adjust the deviation, and it is also prohibited to clean the coal stored on the coal preparation equipment frame and drum. When cleaning the support roller, machine head, and tail drum of the coal preparation equipment, it is necessary to strictly follow the rules and regulations, remember to cut off the power and hang tags to prevent danger caused by someone not knowing that someone is cleaning the equipment and then turning on the power. No one is allowed to sit, stand, walk, lie, or cross on the conveyor belt of the belt conveyor, nor can they stand on the frame to sweep water, shovel coal, or touch the conveyor belt, because some dangers always occur unintentionally; When the coal washing machine frame is a relatively high belt conveyor, protective shields must be installed. Each factory is not allowed to use belt conveyors for handling tools or other objects. Only by correctly protecting the coal washing machine and not violating equipment safety regulations can normal and efficient production be achieved, and thus the interests of the manufacturer can gradually increase.
