Problems and Measures in Mining Machinery Maintenance

I. Problems existing in the maintenance and management of mineral processing equipment 

(a) loose management, daily maintenance is not in place 

The core of maintenance management of mineral processing equipment is to eliminate hidden dangers of equipment operation through daily maintenance. However, as mining enterprises focus on mining and mining in production and operation, they relatively ignore equipment maintenance management, which leads to loose daily management and no clear work flow, staff and responsibility. As a result, mineral processing equipment is often scrapped due to careless management in actual production. 

(2) Extensive management, unable to achieve timely maintenance 

Preparation equipment once put into operation, usually in a state of long-term operation, and due to the processing work difficult, complex, wear, consumption of mineral processing equipment, a certain mechanical failure is inevitable, long under this state managers think equipment maintenance management work also cannot fundamentally change the status quo, so realizes the extensive management, Small problems under regular inspection, frequent inspection and timely maintenance cannot be quickly responded to and dealt with, which will affect the later operation of equipment and bring economic losses to enterprises. 

(3) Backward management and imperfect rules and regulations 

Different mining enterprises of production and operation scale, financial strength, leading to its management concept, management ideology, many small mines and small mining company management is relatively backward, on the one hand was eliminated by other companies will choose the old equipment, on the other hand also lack of equipment maintenance management specialized post Settings, talent introduction, Without relevant rules and regulations to promote the maintenance and management of equipment, it is difficult to find the direct responsible person in terms of equipment selection, equipment application and equipment maintenance. 

(4) Outdated management, lack of professional technology and management personnel 

Many mineral processing equipment failure or even scrap because there is no professional technical and management personnel to guide the operation of front-line staff, guide maintenance personnel maintenance work, improper use is bound to cause the use of hidden dangers, hidden dangers can not be solved professionally is bound to expand the problem. 

Two, mineral processing equipment maintenance and management of effective measures 

(a) improve maintenance management rules and regulations 

To improve the quality of mineral processing equipment maintenance management, a sound maintenance management rules and regulations should be established, which should clearly specify the equipment procurement, application, daily maintenance and regular inspection of the work content, work flow, work reward and punishment measures. For example, when purchasing equipment, it is necessary to conduct preliminary research and evaluation, evaluate the mining scale and demand of the enterprise at the present stage, conduct market comparison in various aspects, and select the beneficiation equipment with the lowest economic consumption cost under the same efficiency. Company internal to the daily maintenance and management processes, such as dressing equipment maintenance management work plan, formulated in advance, matter and afterwards management scheme, clear specific time, regularly patrol supervise inspect specifications, technical requirements, the implementation of the personnel and the succession of patrol personnel, to find problems reported by network, telephone and other ways, Track the follow-up solution of problems and form maintenance management logs, especially special problems in special parts of mineral processing equipment need to be treated carefully and dealt with.

Optimizing post and staffing 

Equipment maintenance and management is a system of professional job content, category, there needs to be responsible for this part of the working talent, people need to know about processing knowledge, equipment maintenance, maintenance knowledge and management knowledge, so you need to begin from the optimize allocation of positions and personnel, enables the preparation equipment maintenance management work to implement. As in the equipment management department to add problem management auxiliary work, reflects the different staff, different department records, sorting, equipment operation issues will have a unified analysis of the causes of accident and to form the next phase of the personnel training manual, through the work of auxiliary equipment maintenance management can be skilled in technical breakthroughs and technological growth. Or in the logistics management department set up dressing equipment maintenance management job, post personnel responsible for the work, need both and equipment providers do technical clarificaiton, daily maintenance, problem analysis, problem and needs to be completed summary record, avoid cross by electricity maintenance or other equipment maintenance workers work, big work load caused by the negligence of. 

Strengthen the awareness of work safety education 

The quality of maintenance and management of mineral processing equipment in many enterprises is not high, the essence of which is that enterprise managers, department staff and front-line operators have weak awareness of production safety, which is just to grab the production period, but ignore the safety particularity of the mineral industry, so it is necessary to carry out safety awareness education regularly. In the training and education, employees should understand the particularity and risk of production in the industry, and the different reasons for the frequent occurrence of various accidents. It also contains the relevant knowledge of the correct use of the equipment,such as how to judge whether there is a running fault of the equipment through the sound and operation phenomenon, and how to quickly respond to the problem and simply deal with the problem through the process. The enterprise also needs to make the staff have long-term production safety awareness and production safety behavior through the establishment of production safety slogans and warning signs.

Ore dressing equipment maintenance and management work are usually made of enterprise logistics department is responsible for equipment maintenance, neither the high-tech talent, also have no specific job responsibilities, scope, so need to change their own personnel management concept, management methods, actively attract such as mechanical and electrical equipment management professional talents to work in the enterprise, is responsible for the specific work, The use of this part of talents can not only improve the overall quality of the company’s management team, but also facilitate the development of refined operation training. In addition, employees and grassroots technical workers should also be encouraged to learn the relevant knowledge of mechanical and electrical equipment, and obtain relevant certificates on the job. Employees who succeed in the exam should be subsidized or rewarded. Enterprises should also provide opportunities for employees to go out for communication and designated training, and promote the development of the mining industry with continuous learning and progress. 

conclusion 

Mineral processing equipment plays a key role in the development of the industry and enterprises. The stronger the mechanical operation and the better the operation result, the better the performance and benefit the enterprise can reap. Although the present preparation equipment in maintenance management does not reach the designated position, not timely maintenance, the maintenance management rules and regulations and management problems such as lack of professional talents, but can be by the transition of the enterprise managers management ideology reverse, such as establishing and perfecting the rules and regulations, optimizes the allocation of jobs and workers, strengthen the awareness of production safety education, training and the introduction of high-quality talent, And the existing equipment is regularly transformed, updated or eliminated, so that the enterprise’s overall mineral processing equipment in a high quality operation state.
