When purchasing coal washing machine equipment, attention should be paid to the "three principles". Enterprises need to purchase equipment according to their actual production technology needs and future development requirements. Fully considering the quality assurance, low consumption, safety, durability, maintenance, completeness, flexibility, environmental friendliness, and economy of coal washing equipment is necessary to ensure the economic operation of the equipment after it is put into production and bring good returns to the enterprise.

　　Establish a three-level enterprise coal washing equipment management network centered on legal entities, including enterprises, workshops, and teams. The coal washing equipment management organization should build a three-level network. Coal preparation equipment manufacturers believe that enterprises should combine their own actual situation. A sound management structure for coal preparation equipment, clear responsibilities, streamlined relationships, and comprehensiveness can be summarized as comprehensive management, full staff management, and full process management of coal preparation equipment. In terms of coal preparation equipment management, "three comprehensive management" should be implemented. Modern coal preparation equipment management is different from traditional coal preparation equipment management. Effectively ensure the technical performance and normal operation of coal preparation equipment, improve its service life and utilization rate, and carry out planned and prepared inspections and maintenance of coal preparation equipment. Strictly control the quality of spare parts. Strive to ensure both quality and strict maintenance of coal washing equipment, strictly implement maintenance plans and regulations, and ensure economic efficiency. Strictly grasp the quality of maintenance and the completion acceptance of technical renovation and maintenance.

　　The coal washing equipment is suitable for the discharge and impurity removal of lignite, easily slimed coal, and low-quality coal, as well as for the discharge and impurity removal of raw coal in coal preparation plants in water scarce and high-altitude cold areas. The side drum coal washing machine of Henan Manlin Heavy Industry Machinery Manufacturing Co., Ltd. is an efficient and energy-saving new type of coal washing machine, which adopts advanced raw coal processing manual and mechanical methods, greatly improving the efficiency of the coal washing equipment, The development of coal washing is conducive to the transformation of coal products from single structure and low quality to multi variety and high quality, achieving high-quality products.

　　There are many users of coal consumption in our country, and the requirements for coal quality and variety are constantly increasing. Some cities require coal to have a sulfur content of less than 0.5% and an ash content of less than 10%. If coal selection is not developed, it cannot meet market requirements. In order to remove gangue from coal and prevent it from dissolving and forming lumps during high-temperature combustion, it is easy to block the furnace or other combustion facilities, and it does not burn to reduce the impact of combustion heat on efficiency.
