ball mill: The extremely large tailings (explained: treasure to be tested) produce and handle
; Currently my country tailings (explanation: Treasure to tap the treasure) library is still stacked In this way, there is too large, the tail mine is planted to the stack, causing the sewage horizontal flow, the bunch of the bunch is very large, the stack is very unstable (explained: stable stability; no change), rain often causes Landslide in the mudslide, has experienced more than 100 deaths. The ball mill is suitable for polishing various ore and other materials, which are widely used in different industries such as mineralization, building materials and chemicals, can be divided into dry and wet-forming milling methods. The ball mill can be divided into a short cylinder mill, a long cylinder mill, a tube mill, and a conical mill. The National People's Congress representative, the Chinese Division Mining Grinding Engineering Academician Wang Mengshi, must pay attention to the harmful tailings production and treatment.
my country's mining industry's economic current task is how to make long-term shelving tails (explanation: treasures to be tested), and conduct secondary development and utilization. Wang Hengshu said that in the Chengde City as an example, as of the end of 2011, the city has a total of tailings (explanation: treasure to taking the dive) library 826, accounting for 1/4 of Hebei Province, accounting for 1/17 in Hebei Province, accounting for 1/17 in the country, accumulating accumulated deposits About 1.6 billion tons, the average annual tailings (explained: treasure to be tedled) increased by about 200 million tons.
The mining does not allow damage to the environment, which is not allowed to regenerate new pollution, which is the responsibility of society. The ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metallogenicity and glass ceramics, etc., dry or wet grinding of various ore and other wear materials. . Wang Mengshu proposed that it is not allowed to tail (explained: treasure to be tested), and the land can specify a small amount of footprint, as a temporary storage requirement. He said that the current tailings grading concentration technology and refining screening technology is high, slow, it is not easy to adopt, making building materials will have new pollution to buildings (building), which is not large, can not eliminate tailings . And, in my country's 90% of coal mines and metal mines use underground mining. It has caused surface subsidence to fall into the collapse. It is very serious about the surface farmland, buildings, roads and ecological environments.
Equipment Factory recommends that tailings (explanation: treasure to be taking the treasure) After a simple cementation, there may be plans to populate the vacuum area, and leave the underground space for future application for new use. The ball mill is a crushing key equipment after the material is broken. The ball mill is suitable for polishing various ore and other materials, which are widely used in different industries such as mineralization, building materials and chemicals, can be divided into dry and wet-forming milling methods. He introduced: Filling the vacuum is an important way for a large number of gastrointestinal tailings. This technology forms the concentrated tailings and gelling materials into a certain component of the filler filling discarded tunnel and vacuum area, forming a setThere is a stunning body of Strength; each cubic filling area can be filled with 2 tons, and all of the firefields can consume 100% tailings in the original mine, thorough.Also, through the filling of the vacuum area, on the one hand, the safety hazard of the underground mining space area can be eliminated, and the ecological damage caused by the collapse of the vacuum area can be used to replace the mine column, which is conducive to increasing the rate of return.
Engaged in energy-saving ball mill, ceramic (raw material: non-metallic mineral) ball mill, tapered ball mill and other ball mill equipment, with advanced patents of ball mill (meaning: public letter or public literature) certificateMore than ten, leading (take the lead) in the industry's domestic ball mill production (Produce) enterprise, quality quality, perfect after-sales, escort your equipment and production!
