Coal gangue is a solid waste discharged during the process of coal mining and the process of coal washing. It is a kind of black -gray rocky rock with a low carbon content and harder than coal in the process of coal -to -coal.
This can be used for sand, and coal gangsters can improve their utilization rate after crushing sand. , Can be used for sand. The sand making machine is widely used in many departments such as smelting, building materials, highways, railways, water conservancy and chemical industries.
The rough break: The coal gangue raw materials are more than ten centimeters. In the case of large particles, enter the vibration feeder through the material warehouse, and make rough crushing through the E -Bybric.
This: The finished product after the rough breaks is sieved, transported to the counterattack break, the medium shatter, and the screening qualified to enter the next program, and the non -qualified return is crushed.
This: The medium fine material enters the third sand making machine for plastic surgery, 5mm out, and then enter the sand washing machine for cleaning.
The process chart
Coal vermiculite is the largest industrial waste in China, accounting for about a quarter of my country's industrial solid waste. According to the materials of relevant departments, the cumulative coal vermiculite that has been piled in the country over the country has been about 3.6 billion tons, about 2,600 stones with large scale, covering an area of 12,000 hectares. With the development of my country's modern construction and the increase in environmental protection, the development of clean coal technology, and the improvement of the level of coal mining mechanization, the amount of emissions such as coal gangs and mud will increase. The largest coal production in Shanxi Province, currently the accumulation of coal gangsters has reached more than 1 billion tons, forming more than 300 vermiculite mountains. In recent years, with the rapid growth of coal production, about 80 million tons of coal vermiculite is added each year. Experts from coal processing and utilization introduced that coal gangsters with calories from 300 to 1,000 calories can be replaced by all or part of clay to produce new types of building materials such as coal vermiculite empty heart bricks and vermiculite cement. Do not use coal burning bricks. " The coal gangue, which meets this condition, has a total of about 138 million tons of the country in 2005. If all these coal vermiculite are used for brick -making, 42 billion coal bricks can be produced, which can save savory vermiculite piles to occupy more than 5,500 acres of land and more than 5,500 acres. , You can replace the clay to do less bricks to destroy 30,000 acres of land (calculated by 3 meters of pits), saving more than 5.6 million tons of commercial coal

Coal vermiculite is a solid waste discharged in the process of coal mining and coal washing. It is a kind of black and gray rock with a low carbon content and harder than coal in the process of coal -to -coal seams. In addition, there are also small amounts of FE2O3, CAO, MGO, Na2O, K2O, P2O5, SO3, which are unequal. Combined with the research and analysis of industry experts, coal gangsters are excellent brick -making raw materials in terms of physical performance or chemical composition. Therefore, the treatment of coal gangsters is the key.
For a long time, Shenpeng Environmental Protection has focused on the research and development, production and promotion of solid waste and environmental governance. By adopting advanced equipment, the coal gangue can be removed by the selection of physical color selection during the crushing and cleaning process. Miscellaneous, then multi -level crushing grinding and screening is processed into a new type of environmentally friendly imitation wood products or firewood wall board raw materials, thereby replacing the national limited and scarce wood products to meet the needs of national ecological development.
