Increased competition in the mining machinery industry to save the cost of beneficiation

Since 2012, domestic ore prices have fallen sharply, but due to the high mining ore processing costs, the development of mining companies has been hindered, and some have even closed down. In fact, in the environmental situation of this kind of mining industry, it is crucial for companies to continue to survive and save mine costs.

A large part of the mine's cost comes from beneficiation, so if you want to save mine costs, the cost of ore dressing is a top priority. For the beneficiation plant, the cost mainly consists of the cost of the basic construction of the mine in the previous period and the operating costs after the commissioning. For today's mining companies, the rational design of the concentrator and good equipment selection are good ways to save the cost of ore dressing.

Reducing the cost through rational design The concentrator design is to physically or chemically separate ore or other raw materials from the useful minerals and gangue or impurities to meet the plant design of the smelter or other users. The design work of the beneficiation plant is based on the expertise of the beneficiation process as a mainstay, and other related professional assistance and joint design. By rationally designing the ore dressing plant, the initial investment cost of the beneficiation plant can be effectively reduced. For example, the site selection should avoid land acquisition and demolition and relocation as much as possible, which can reduce the burden of large land expenses and compensation for demolition. If the beneficiation plant is built alongside the mountain, it is necessary to ensure that the slurry can flow and save a lot of slurry transportation costs.

But to design properly, the best way is to entrust the design work to an experienced design institution or company with strong R&D capabilities. The design work of the beneficiation plant is based on the beneficiation process, with the assistance of other related professionals and the overall design.

For small and medium-sized mines where capital and technology are relatively lacking, it is a good choice to entrust the basic construction of the mine to a general contractor who is experienced and skilled. The mine engineering general contractor can complete a series of projects such as the completion of beneficiation tests, plant construction, equipment manufacturing and installation, and can plan the entire mine construction as a whole. The mine owners can even hand over the design, equipment supply or procurement, and construction of the entire project to a qualified mine engineering contracting company. They can control the project according to the budget and make reasonable arrangements.

Yantai Xinhai Mining Machinery Co., Ltd., which was the earliest project to carry out mine general contracting projects in the country, has 20 years of history and experience in general contracting projects. It has completed more than 400 mine engineering projects and has exported its products to overseas companies. The package project involved more than 30 countries such as Russia and Mongolia. For example, after the production of the Mongolian Mongol Garar gold mine project undertaken by Yantai Xinhai was put into operation, the comprehensive recovery rate of mineral processing has reached 94%, which is 2% higher than the design proposal proposed by the Canadian company at the time of bidding, and the construction period is also shorter than the schedule. Quite a lot, reducing the amount of engineering design costs. And the general contracted project avoids the mutual push by the contractor after the problems in the ore dressing plant, improves the quality of the project, and reduces the equipment repair costs in production.

The choice of equipment can not only look at the choice of price mineral processing equipment will also have a significant impact on the cost of ore dressing, in the purchase of mineral processing equipment, it is definitely not the lower the price, the more cost savings. On the contrary, if you choose a relatively high-quality, more energy-efficient and relatively expensive equipment, you can avoid the loss caused by equipment failure during the production process, which will save a lot of energy costs during the production line operation. In the feldspar beneficiation plant of Yantai Yitao Mining Co., Ltd., Yitao used ultra-thin laminated self-grinding machine developed by Yantai Xinhai, although the investment cost of equipment was more than that of traditional equipment, but the power consumption during the grinding stage was reduced. 60%, the processing efficiency has been doubled; at the same time, the medium-fine-siege screening plant, equipment and dust collection unit have been omitted, saving civil engineering investment, saving floor space and greatly reducing production costs.

At the same time, the equipment with good energy-saving effect and high automation can also save the power and labor costs in the production process. However, many mine owners only care about the immediate interests. Early installations of equipment with lower quality and lower prices have adversely affected the production of mines in the future. Not only do the selection criteria fail to meet the requirements, but even a large amount of money is required to repair them. Old equipment and purchase new equipment.

For example, in the feldspar beneficiation plant of Yantai Yitao Mining Co., Ltd., Yantai Xinhai ultra-thin laminating self-grinding process was creatively adopted, although equipment investment in new equipment was 2.4 million yuan more than traditional equipment, but crushing grinding The power consumption at the stage was reduced by 60%. At the same time, the medium-fine-siege screening plant, equipment and dust collection unit were omitted, the civil construction investment was saved, the floor space was saved, and the production cost was greatly reduced.

In addition to energy efficiency and efficiency, the equipment with good wear resistance and long service life can also reduce equipment consumption costs. Equipment life also affects production costs. Xinhai wear-resistant rubber developed and produced by rubber lining machinery of Yantai Xinhai Mining & Mining Machinery Company Products are typical examples of this. By lining Xinhai wear-resistant rubber in the over-flow area of ​​mining machinery and lining the wear-resistant rubber cyclone, the average utilization rate of the equipment is increased by 3 to 10. The life span can be extended by 2 to 5 times, and the equipment can be replaced and maintained conveniently. Reduced management costs. In addition, the highly automated equipment can also save labor costs in the production process.

However, many mine owners only care about the immediate interests. Early installation of equipment with lower quality and lower prices has adversely affected future mine production. Not only does the beneficiation index fail to meet the requirements, it even costs a lot of money to repair the old ones. Equipment and acquisition of new equipment.

In today's increasingly fiercely competitive mining industry, the control of cost savings is undoubtedly an important ability. It has become a necessary measure for increasing the competitiveness of various mining companies and is an important indicator to measure the competitiveness of mining enterprises. In the period of low mineral resource market, limited cost control will bring huge competitive advantage to the company. At the same time, it will also develop rapidly because of increasing attention.
