Recycling of Scrap Steel Crusher to Promote Sustainable Economic Development by Utilizing Scrap Steel Resources
Scrap steel is a raw material that can replace iron ore in steel production. To some extent, the development and application of scrap steel resources is an important way for the steel industry to achieve energy conservation, emission reduction, clean production, circular economy, and alleviate the crisis of iron ore resources. The recycling rate of scrap steel in China in 2012 was 19.9%, far below the world average of 48.3%. The trend of the development of China's scrap steel processing industry is to use scrap steel crushers for sorting and processing, and utilize high-tech such as environmental protection and mechatronics integration to develop new comprehensive scrap steel treatment technologies, which can form an environmental protection industry and new economic growth points.

The recycling and utilization of scrap steel is not ideal, and the next 5 to 10 years will usher in a golden period
According to relevant data, China's scrap steel is currently entering a period of rapid growth and may reach 300 million tons in the next decade. Scrap steel is one of the main iron raw materials for steelmaking, which not only carries energy and saves energy, but also is environmentally friendly. However, for a long time, the recycling of scrap steel has not been ideal.
The new project of Tangshan Xinhu Mining Machinery has won unanimous praise from the observation team
On September 4th, more than 100 city leaders and attendees, including Li Guifu, Secretary of the Zunhua Municipal Party Committee, and Dong Xuezhong, Mayor, used a day to conduct on-site observations of 30 key projects recommended and reported for the first half of 2017 in 27 townships (streets) and 6 economic authorities in the city.

Mining machinery technology development trend in the future
The technology level of mining machinery and equipment capacity, is a measure of a country's industrial strength important symbol. This paper briefly introduces the classification of the mining machinery and role in national economic construction, and put forward the economic construction oriented market driven, computer technology and information technology, and other multi-disciplinary integrated support as well as the harmonious development between human and nature is the driving force for the development of the mining machinery manufacturing.

The main ways to improve the efficiency of ball mill output
The main ways to improve the efficiency of ball mill output 1, the grinding system automatic control. According to the noise of ball mill, electric ear method is used to control the electromagnetic vibrating feeder or belt feeder, automatic regulation and control grinding material within appropriate materials uniform to join, make the material inside the mill keep the best state, which can improve the mill production. 2, strengthen to ball mill (ball mill) ventilation in grinding. Has a certain wind speed grinding, the grinding process of powder can be taken away by the airflow in time, reduced the buffer action of micro powder, can improve the efficiency of grinding, the quality of the products will not be affected. Grinding in ventilation speed due to grinding different materials and different, generally 0.3 1.0 m/s. When the well ventilated, ground water vapor discharge in time, within every storehouse board grate hole is not blocked, grinding medium adhesion phenomenon is reduced, and can reduce the temperature in grinding, this is advantageous to the mill operation and improve the quality of products. Production of high strength grade of cement should choose low speed; Conversely should choose a bit bigger. 3, into the ball mill (ball mill) ground water inside. Should produce a lot of heat when grinding cement, the quality of cement and the grinding efficiency are bad, and affect production. Water with high pressure air atomizing spray into the grinding, grinding away effectively within the quantity of heat, cooling in the mill. Water is a surface active substance, easy to make particles get nexus of contracts for collapse, prevent package material on the grinding medium. Within the water spray is determined according to the grinding temperature and grinding, generally not spray under 1000 c. In addition, water quantity according to the grinding clinker temperature, accounts for about 1% - 1% of cement quantity, and the spray into the ground moisture to evaporate completely, no residual moisture. Water from the grinding head or tail water spray can. When the grinding material at high temperature, water from the grinding head is advantageous, whereas in the general case is grinding of tail water spray. In the grinding water can make the production capacity increased by 5% - 10%. To ball mill (ball mill) mill grinding agent, can improve the production capacity of around 10%, general with triethanolamine, mix accounted for 0.04% of the grinding material - 0.1%.
