Mining equipment obsolescence appraisal

The scrapping of mining equipment refers to the state in which the equipment has reached its design life or cannot continue to be repaired and maintained, and can no longer be used. After mining equipment is scrapped, it needs to be processed and disposed of. Any factors that may affect the safety of the equipment are considered important factors for scrapping. For example, a serious malfunction of the machine or structural defects of the machine are all factors that affect the safety of the equipment.

As an independent third-party appraisal agency under Guoke Holdings, Zhongke Testing has the qualifications for fixed asset scrapping appraisal. It can organize technical personnel to evaluate the assets to be scrapped and evaluate and issue a mining equipment scrapping appraisal report based on the list of assets to be scrapped and relevant information provided by the client.

The principle of equipment scrapping is: use equipment with advanced technical performance to replace old equipment with backward technical performance that cannot be repaired or modified. Equipment that meets one of the following conditions can be scrapped and updated:

1. Old, old and miscellaneous equipment with aging equipment, backward technical status, high energy consumption, low efficiency or exceeding the specified service life;

2. Through repair, Although the accuracy and performance can be restored, the one-time repair cost exceeds 80% of the original value;

3. It seriously pollutes the environment, endangers personal health and is uneconomical to modify;

4. It suffers from accidental disasters, is seriously damaged and cannot be repaired;

1. Equipment Assessment: A comprehensive assessment of the mining equipment to be identified. Evaluate the appearance, working status, service life, etc. of the equipment. Check the equipment for serious damage, wear, corrosion, etc.

2. Usage history: View the service life, repair records and maintenance status of the device. Understand the age, frequency of use and operating environment of the equipment, and determine the health status and remaining life of the equipment.

3. Technical evaluation: Conduct a detailed analysis of the equipment to evaluate its performance, reliability, safety and economy.

4. Inspection and testing: Use appropriate inspection methods and instruments to conduct actual inspection and testing of the equipment. For example, check the working status, accuracy, electrical performance, etc. of the equipment, and evaluate whether the equipment meets the expected use requirements.

5. Risk assessment: Based on the evaluation results and testing data of the equipment, evaluate the safety, reliability and economy of the equipment, and analyze the risks and impacts that equipment scrapping may have on production efficiency and work safety.

A mining company has a batch of mining, mineral processing and transportation equipment that is idle. In order to determine whether this batch of equipment has reached the scrapping condition, our company has been entrusted to appraise whether the mining equipment has reached the scrapping status.

Identification and analysis results:

Identification and analysis The expert group conducted on-site inspection and survey results on the mining equipment entrusted for identification and evaluation, and made the following recommendations and conclusions:

The mining equipment has reached a scrapped state.

1. Equipment list sorting: First, it is necessary to sort out the list of all equipment, including the name, model, specification, quantity, purchase date and other information of the equipment.

2. Equipment condition assessment: Evaluate the condition of the equipment based on its usage and maintenance records. It can be carried out through regular inspections, random inspections, etc.

3. Expert appraisal: For some highly professional equipment, experts in related fields need to be invited for appraisal. Experts can evaluate the condition of the equipment based on its performance testing, technical indicators and other factors.

4. Processing decision making: Based on the identification results of the device, make corresponding processing decisions. If the equipment can be repaired or upgraded, it needs to be processed accordingly; if the equipment cannot continue to be used or the repair cost is too high, it needs to be scrapped.

5. Execution of equipment scrapping: Dispose of scrapped equipment in accordance with relevant regulations and procedures. For example, recycling, dismantling, and destruction of equipment. At the same time, appropriate record and file management work needs to be done.
