China Grinding Media Remodeling Has Been Top Level
China grinding media remodeling has been top level
To analyze the change of grinding mill consumption per unit of China's iron ore concentrator from 1986 to 1995, it is easy to see that it dropped O l7 kg / t. Calculated as 246 million tons in 1995 iron ore production for China's iron ore concentrator ball consumption of steel by 41 860 t. Value of 1.2558 billion yuan. During this period due to the iron ore concentrator emphasis on reducing consumption of steel, generally carried out the testing and promotion of the grinding media, has made great achievements. , Anshan Iron and subordinate concentrator 1986 to 1995 10 years, average ball consumption decreased by 023%; especially Donganshan the concentrator ball consumption decreased most significant, are shown in Table 53-6. To sum up 1981 and 1995, the progress of the grinding media has taken two big step First, forging, casting, heat treatment, a significant reduction in the unit consumption of grinding media; the implementation of low-chromium alloy the low quality of ball gradually out of the market.
10 years in the late 20th century to the early 21st century. A large number of annual handling capacity of below 500 000 t of small iron ore dressing plant growing generally abandoned the concept of grinding media cost-effective, energy saving affect the iron ore concentrator. However, China's former subordinates focused on iron ore concentrator still insist on the use of high-quality grinding media for many years and new varieties of research, development and promote the use of the dominated. Mainly in the following aspects. Iron ore beneficiation factory of Angang Group mining company Qidashan from the United States with three large grinding equipment, ball mill size of φ5 49 m × 8.83 m ball mill 6, is the nation's largest mill. Order to reduce the grinding media consumption, further improve the grinding efficiency, Anshan Iron Mine wear-resistant materials, the company developed a
