Equipment scope of use: This equipment is used for washing high-quality refined coal for smelting, suitable for coal washing plants with an annual input of 100-4 million tons.

　　Washing effect:

　　1. Clean coal ash content: Increase by 10-20% on the basis of the ash content in the raw coal (according to the characteristics of the washed raw coal).

　　2. Quantity efficiency: 90-95% (based on the characteristics of the washed raw coal).

　　3. Moisture content of clean coal: 8-11% external water (based on the characteristics of the washed raw coal).

　　4. Desulfurization rate: can remove 80% of inorganic sulfur.

　　5. The water circulation system of the equipment achieves full closed-loop circulation, without sewage outflow and environmental pollution.

　　The main performance characteristics of the HXSKT series combined coal preparation equipment are as follows:

　　The HXSKT coal preparation system is divided into subsystems such as the main washing system, flotation system, concentration and filtration system, and belt conveying, screening and crushing system. It can be combined and designed according to any subsystem and multiple subsystems.

　　2. Change the structure of the multi-level factory building to a planar three-dimensional structure, and only the planar equipment foundation is needed to complete the installation and layout of the complete coal washing equipment. Compared to traditional processes of the same scale, the total investment is reduced by about 50%, the washing cost is reduced by about 60%, and the economic benefits are greatly improved.

　　After the completion of the foundation of the factory's flat equipment, each individual equipment is installed in place, and outdoor operations on the flat surface ensure fast installation work, greatly reducing the construction period of the factory.

　　After the equipment installation is completed, a light steel structure factory building can be built or not built according to the surrounding environment of the coal washing plant. Strong investment selectivity.

　　5. The HXSKT series combination intelligent jigging coal preparation equipment adopts a closed circuit water circulation system, which is energy-saving, water-saving, and has no environmental pollution.

　　The application of deep cone concentration technology can ensure efficient water purification while achieving layout inside the factory, especially suitable for winter production needs in cold regions, with a small footprint and no need for a large number of civil engineering projects.

　　The HXSKT system's new type of jigging machine is equipped with a complete intelligent CNC system, ensuring the adaptability of the combined intelligent jigging coal selection equipment to coal types, which can wash coal for electricity and coke. The washing efficiency is high, which is 2-3% higher than that of ordinary air chamber jigs.

　　8. For high value-added coal, adding flotation systems can further improve the recovery rate of clean coal and bring greater economic benefits to users.

　　9. The system has a high degree of mechanization, low labor capacity, convenient equipment installation and maintenance, stable equipment performance, minimal maintenance, and can be continuously produced.
