From the perspective of the operation of coal washing equipment throughout its lifetime, the planning of the equipment has a significant impact on the comprehensive benefits of the equipment. While maintenance is important, in essence, it is only a remedial measure after the fact, and problems in design and manufacturing cannot be solved solely through maintenance.

　　Generally speaking, the key to reducing equipment costs lies in the planning, design, and manufacturing stages of the equipment. Because at this stage, the cost of equipment (including the use of equipment, the amount of construction work, and the cost of ancillary devices) has basically been determined. Obviously, exquisite and excellent design will greatly reduce the cost and life cycle cost of the equipment, and the performance will fully meet the requirements.

　　The life cycle cost of coal washing equipment mainly depends on the planning stage of the equipment, as shown by research; When the equipment is planned to 50%, the actual expenditure is 20% of the cost, but 85% of the equipment's lifespan has been determined. The cost is high in the later stage of planning, but the impact on the life cycle cost is not significant.

　　If the early management of coal washing equipment does not involve the design and manufacturing of externally purchased equipment, the life cycle cost of coal washing equipment generally cannot be directly controlled. So, the primary task is to grasp the two key links of equipment planning and decision-making, as well as the selection and purchase of externally purchased equipment. By doing this part of work well, we can grasp the key points of preliminary work and basically do a good job in equipment management.
