After the investigation of the Red Star Machine, it was found that as the degree of mechanization of coal mining increased, the proportion of pulverized coal and the last coal in the raw coal increased, which resulted in the raw coal slime from the thermal coal washing plant and the coking coal washing plant. The flotation tail coal volume has increased significantly. So can these tail coals that are similar to tailings be properly utilized like tailings? As a by-product of the washing process, slime has the characteristics of fine particle size, strong water holding capacity, high ash content, and high clay content, which brings a lot of inconvenience to the comprehensive utilization of slime. At present, most of the coal slime from the processing plant is sold to local farmers at a low price, which pollutes the environment and wastes resources. The value of coal slime has not been truly reflected. According to the technical personnel of Henan Hongxing Mining Machinery Co., Ltd., the new slime drying process is to solve the problem that coal slime cannot be comprehensively utilized due to high moisture (20% to 30%). This technology adopts a new technology that crushes and disperses the coal slime and then heats it to dry. The treatment of the slime is continuous and industrialized. After the treatment, the moisture of the slime can be reduced from 25% to 28% to 12%. Around, due to the introduction of the pre-shredding dispersion process in this process, the drying efficiency of slime has been greatly improved. The dried slime can be mainly used in the following aspects: as a raw material processing slime briquette, for use in industrial boilers or residential life; as a power plant fuel, reduce production costs; as a brick factory additives, improve the quality of the brick; as Cement plants add materials to improve the performance of cement; slime containing certain specific ingredients can be used as chemical raw materials. Comprehensive utilization of coal is the only way for coal companies to change their single operations, and it is the hope for the coal industry to turn losses into profits. In recent years, China's coal resources have become increasingly scarce, and the annual sludge output has exceeded 20 million tons. Therefore, the use of slime is very urgent. The new coal slime drying technology of Hongxing Machinery has opened up a new road for the comprehensive utilization of coal slime and provided technical assurance for the design of slime drying plant. After the slime has been treated by a drying process, the way of its utilization has been expanded, and the added value of the product has been improved. This not only saves energy and improves efficiency, but also reduces environmental pollution in the mining area. Redstar machines will continue to work hard on the drying of slime and other materials to contribute to the scientific research and construction of drying technology! Metering Nozzle
