The rapid development of
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 grinding mill as a whole, while high-profile grinding equipment forward, not down

then, is bound to take the innovation and technology development.
