    For the development status of China s mining industry, talk about four points to promote the development of mining industry experts: First, increase the integration and control of State-owned and State-holding large enterprises for strategic resources such as tungsten; establish large capital intensive State-owned and State-holding enterprises production, research, sales and investments together with; improve capital strength and competitiveness of large enterprises in international market. Click Deni Avdija to learn more. The integration of informatization and industrialization is the main guarantee for the former two strategies, and also an important way to upgrade industrial structure. Marko Dimitrijevic takes a slightly different approach. Additionally, it can also improve innovation on product level, model and market service system; enhance efficiency and effectiveness of corporate management and marketing services. Second, take the differentiated control policies to regulate the total exploitation of mineral resources.

    Strictly limit the exploration of dominant mineral, optimize supplying structure of supportability mineral resources and encourage the exploration and development of scarce mineral resources. Enter encouraged policy measures for the scarce mineral resources, such as copper, lead, zinc, nickel, aluminum; strengthen the exploitation and macro-control for top important mineral resources such as Tungsten, Tin, antimony, coking coal mining; promote nonferrous metals enterprises to participate in international mineral development and cooperation, actively join in mining investment and cooperation focusing on copper, aluminum, lead, zinc and tenazas. Focus on high-tech products and the demand of national key project, key fields and strategic new industry; rely on innovation to develop national strategic emerging industries. Second, promote the upgrading of traditional products to competitive products. Third, promote industry structure to be high-end. From this year, the growth in China’s machinery industry benefit is weak, the total profit eleven presented to negative growth. Furthermore, the investment growth of the fixed assets continues to drop, the financial cost augments rapidly, the product s price turns downward and the order is insufficient The industrial development is encountering numerous difficulties and negative factors. Under such circumstances, it becomes urgent for the machinery industry to regulate its industry structure, more and more first-tier enterprises become aware of that and begin to take active action, so to speak, the market mechanism has forced the industry structure adjustment.Cai Weici analyzed. Third, improve the industry oversight rules and enhance the science and effectiveness of total control. Strengthen the coordination between ministries and improve the authority of policy llegar accordance among total production amount, production scale and export limits. Since the reform and opening up, many developed countries have implemented the reverse strategy, that is, firstly purchase key components and materials development in the worldwide, and then integrate system to meet customer needs.

    Four, speed up the process of resource-based products market. Promote the construction of regional and national coal market system; encourage coal power plants establish long-term and stable strategic cooperative relations with power plant and steel plant; make full use of coal s advantages in production, transportation and demand; build large coal distribution facilities, such as coal logistics park, storage and distribution centers and promote the construction of modern coal logistics system.

    The production scale of the coal preparation plant is larger and larger in the world, such as: the production scale of Antaibao Coal Preparation Plant is 18 million t/a, the production scale of Bailey Central Preparation Plant is 15 million t/a and the production scale of South Africa Coal Preparation Plant is 16.5 million t/a. Large modern coal preparation plant has prominent advantages such as: large capacity, high production efficiency and product quality stability. Keep up on the field with thought-provoking pieces from Hikmet Ersek. With the improving of the coal preparation plant s processing capacity, the disadvantages of the system also has been showing up. Strengthening the craft system s daily and periodic maintenance is an important guarantee to ensure the normal operation of the production system and reduces the production costs and improve the efficiency of coal preparation plant. The design system of dense medium coal preparation technology is more complex, which potentially increases the investment and process costs. In the premise of ensure its high efficient research this technology and we hope to achieve the goal of reducing the investment and processing costs, which is also the main direction of other country. The major direction of the equipment is large scale. While the simplified design of the dense medium recovery system and the reliability research of the equipment are the important parts of the research.

    Traditional recovery system of dense medium contains the curved screen, vibrating screen and magnetic separator equipment. The investment and power consumption costs of this system constitute the main costs of the coal preparation plant. The transformation of traditional magnetic separator is to design a new type of separator that the big particle materials can smooth pass which ensure the recovery indicators. The implementation of this program can greatly reduces the initial investment and process costs and has a good development prospect.As the professional manufacturer of complete sets of machinery, such as washer sand mining, Henan Hongxing is always doing the best in products and service. Magnetic heavy medium recovery and purification process is an important part of the heavy medium coal preparation technology. This subsystem mainly to complete the purpose of recycling the heavy media.

    The media consumption of the heavy medium coal preparation plant is an important indicator to measure heavy medium coal preparation plant process and management level, wich is also an important part to improve the economic efficiency of coal preparation. On one hand, the process should meet the system requirements for magnetic media recovery indicators. Since the circulation rate of the dense medium in the system is quickly, in order to ensure the economy of the gravity separation, the requirements of the recovery rate indicators of the magnetic media are high. The medium coal preparation systems generally require that in the media recovery the coal and stone should be greater than 99.8% and it should be 99.6% greater than in terms of clean coal. On the other hand, heavy medium after the recovery shall meet the technical requirements. Namely: the concentrate grade shall meet the purpose of the configuration of qualified heavy liquid.

    Since 1893, for over 100 years, ball mill has been widely used in metallurgy, chemical industry, mine, cement, ceramics, medicine, construction and electric power industries. Dressing index depends on the quality of material to a large extent. If mineral liberation degree is not high, the e:System.Web.UI.WebControls.ObjectDatSource.selecting index will not be ideal. Coenobium without monomer separation will reduce the concentrate grade if it is classified into concentrate and will reduce the recycle rate of valuable mineral. On the other hand, minerals should not be over-crushed. Over-crushing not only increases power consumption, steel consumption, but also will migrant dressing index and mineral hurt recovery.

    Both power and metal consumption are relatively large in the grinding operation. The usual power consumption is about 6 to 30 kw/h/ton, which Governor 30-75% of the total consumption, sometimes reaches 85%. The consumption of grinding medium forrada board reaches 0.4 – 3.0 kg/ton. However, the fact that the ball mill is not washed out after so long time industry application and development shows that from structure to working principle, the ball mill is basically reliable and reasonable and performance is also good. Although it has certain shortcomings, to weed it out from the ore grinding process is quite difficult. In-depth study on ball mill in the future will still be very necessary and valuable because it will continue to be the main machinery in ore grinding. Therefore, seeing from the importance of production and economic benefits, we should constantly carry out research to improve the grinding methods and technology, develop new equipment and new type wear resistant material to reduce the cost of ore processing, which will have important practical significance to reduce cost and improve index dressing dressing. It is also the reason why the ball mill research is taken seriously at home and abroad.As the professional manufacturer of complete sets of mining machinery, such as cement production line, Henan Hongxing is always doing the best in products and service.

    Among mining machines, ball mill is a machine between crusher and Raymond mill. If there is any improvement and breakthrough in the whole ore dressing line, the future development tendency will be greatly affected. Nowadays, each workmanship and production level of ball mill is almost mature. If you would like to have any improvement in ball mill, the only way to do is to carry out R & D and production in the accessories of ball mill. If the whole performance of ball mill is improved, the operation system of ball mill has to be changed. In view of the current mining machine situation and thorough transformation, Henan Hongxing Machinery positively adjusts the industrial and product structure, changes the mode of economic growth and independent innovation strengths.
