After long-term use, the grinding mill equipment will encounter various problems to a greater or lesser extent, which will affect the working efficiency of the equipment and the interests of users. To avoid this situation, it is necessary to identify the problem and take targeted measures. Only in this way can the working efficiency of the ore grinding mill not be affected, and not only can the service life of the machine be extended accordingly It also extends the average failure interval of the grinding mill, effectively prolonging the service life of the grinding mill and reducing the probability of equipment failure.
When conducting an average fault 瘅 interval time analysis, the reasons, phenomena, required working hours, downtime, construction personnel and the number of people for the maintenance and repair of the grinding mill equipment should be compiled into an analysis table. Then, statistical analysis should be carried out to determine the items that can reduce maintenance work, select the more appropriate repair cycle and inspection cycle, select or revise the inspection items and inspection standards, and improve the repair methods. Estimate working hours, improve operation methods, etc.
The inspection of grinding mill equipment is classified into six types based on the inspection cycle and methods: daily inspection, regular inspection, key inspection, total inspection, precision inspection and disassembly inspection.
1. Daily inspection
All the grinding mill equipment is subject to continuous round inspections by the on-site production workers within 24 hours. This kind of inspection, which accounts for 20% of the total inspection volume of the grinding mill equipment, is the basis of the inspection. The purpose is to detect abnormalities through the five senses of the operators on the job, such as sight, hearing and touch, eliminate minor faults, and continuously maintain and service the grinding mill equipment to ensure its normal operation.
2. Regular inspection
It is carried out by professional inspectors who, relying on their senses and simple instruments and meters, conduct regular and detailed inspections of key grinding mill equipment. This kind of inspection is the core part of the inspection work and is more technical and difficult than daily inspections. It not only relies on experience but also on the combination of instruments and meters, tendency management and technical diagnosis for spot checks. The main purpose of regular inspection is to determine the degree of performance deterioration of the grinding mill equipment, adjust the main parts, and maintain the specified performance of the grinding mill equipment.
3. Key Inspection Points
It refers to the irregular gathering of all the workers on the main grinding mill equipment to conduct a relatively thorough inspection of a single grinding mill equipment. This kind of inspection not only conducts a thorough check on the grinding mill equipment, but more importantly, it serves as a good supplement to the imperfections in the daily inspection by the on-site workers.
4. General Inspection
It refers to the irregular inspection of the grinding mill equipment of different systems, which is carried out in a centralized manner by professional inspectors. Such as hydraulic system grinding mill equipment or all fasteners, etc.
5. Precision Inspection
It refers to the spot checks carried out on relatively critical parts through inclined management methods and technical diagnostic means. This kind of inspection is carried out by technicians and inspection workers using instruments to carefully measure and analyze the precision of the grinding mill equipment at irregular intervals, maintaining the specified functions and precision of the grinding mill equipment.
6. Disassembly inspection
It refers to the partial or complete disassembly of the main grinding mill equipment, and the qualitative and quantitative inspection of the wear, fatigue, damage and other conditions of each main part is carried out together by security personnel and dedicated inspection personnel.
