Grinding Mill Equipment How to Promote Energy Development

10/13/2010 4:24 AM

The rapid development of
grinding mill in China for coal, metal and nonmetal mines the development of more advanced international standards of quality, efficient equipment to meet economic development needs for energy and raw materials of great significance.

Depth study of international and domestic grinding mill industry status quo, development trend and industry technology trends, particularly in advanced technology equipment, crushing mill, and put our country engage in the further development of grinding mill manufacturing level has profound significance. grinding mill industry as a pillar industry of national economy in China's economic construction and social development plays an important role. In mining, energy, transportation construction, and industrial raw materials and other industries, mining mill, grinding mill and materials for construction of deep-processing equipment, a steady stream of businesses provide a lot of basic industrial products and energy, great protection of the national economy the healthy and rapid development. Therefore, grinding mill manufacturing industry a national basis to establish an independent industrial system, but also to measure a country's symbol of industrial prowess.

Coal is China's most important energy in its social and economic development play an extremely important role. The development and use of coal, both on the social economy plays a significant role in promoting, but also had a significant impact on the environment. Gangue and coal bed methane development is the main waste generated in the process, the coal industry has long been regarded as hazardous substances and severe gas. After the third plenary session, with the deepening of economic reform and rapid development of the health industry and agriculture, in the case of energy increasingly scarce, people gradually realized that these wastes are still available for the use side. Particularly in the last twenty years, the coal sector in the development and utilization of coal gangue and coal bed methane exploration and done a lot of production test achieved a number of results. Practice has proved that as long as the changing concepts, scientific research, according to local conditions attention to the development of coal production during the secondary use of mineral resources is not only feasible, but has great potential; not only of harm into turning waste into treasure, and can save energy, and access to major social and economic benefits. Coal gangue in the tunneling, mining and washing process in the discharge of solid waste. Is carbon, a mixture of mud and sandy shale, with low calorific value. 20% to 30% carbon, and some containing humic acid. Coal has been accumulated over the years about China 1000Mt, and each year continues to emissions of about 100Mt, not only accumulation of land, but also pollute the air or cause a spontaneous combustion fire. In recent years, with the comprehensive utilization of coal gangue in various sectors of the rapid rise of consciousness, how to change waste into treasure gangue? Use at home and abroad have developed many ways. The basic principle is the basis in identifying the nature of the gangue and treat them differently, making it the best use, and use a variety of ways to combine the development of a certain size and utilization system to get the best value for money. According to China's actual conditions, its use roughly five areas:

1. Coal mine filling. Gradual reform in the mining process, based on the direct use of coal waste in the pit filled gob or processed in the ground filled with underground mined area.

2. Coal mining subsidence area filling, reclamation of wasteland and road.

3. Gangue power generation. Containing carbonaceous more high heat coal gangue, can be used as fluidized bed and circulating fluidized bed power generation.

4. Production of coal gangue brick, cement and lightweight aggregate and other building materials.

5. Extracted from the gangue concentrate and other chemical products.

No matter what approach is used in coal gangue, coal gangue is the ultimate jaw crusher, impact crusher, Raymond mill, etc. and the comprehensive utilization of processing equipment.

Broken inside the milling equipment is an important grinding mill components, including jaw crusher, impact crusher, and other broken equipment and Raymond mill, high pressure micro powder mill, ultrafine powder mill, Super milling machines and other large industrial uses dozens of different devices, not only in minerals, coal, electricity, chemicals, building materials, refractory, metallurgical, water, construction and highway industries processing raw materials play a big role, but as railways, highways, utilities, municipal engineering, construction to provide the efficient, reliable technical equipment support. Rapid progress in the Pulverizer as a whole, while high-profile grinding equipment forward, not down then, is bound to take the innovation and technology development.
