Gangue is the solid waste in the process of coal mining & washing with the main component of alumina, silicon oxide, iron oxide, calcium oxide, magnesium oxide, sodium oxide, etc. The gangue emissions occupy 10%-15% of the total coal emissions. Thanks to the recycle economic development of coal industry’s rapid development, gangue is recycled at a great amount, which is a new type of environmental building material in the market now.
Using the gangue to replace the building brick lowers the cost and without watering before walling & painting, which saves water and fees. Because of higher hardness, it has an advantage of lower consumption of transportation. What’s more, the gangue replacing the building brick can reduce the pollution which is caused by an amount of gangue waste piling high on the earth or the damaging to the water system resources as well as making the fire-resistant brick of high hardness which is higher than clay brick so as to save the earth resource. In a word, gangue replacing building brick is an engineering of recycling economic, good for country and people.
After the crushing, gangue is added with yellow mud to mix together, then after the ageing to enter the model, the model is fired to the finished product after baking. It’s important to increase the plasticity of semi-finished product, which needs the technology of proper fine crushing and maturing. So far Liming Heavy Industry manufactures the most professional gangue crusher, which compiles the granularity needed completely and is good to improve the plastic blank. Liming gangue crusher has a special design with a simple operation. What’s more, the managing, running and maintaining fee is lower than other crushers. Each production line is under 24 hour inspection with safe checking on quality before permission out of plant.
Gangue crusher reduces the cost investment for customers. In the traditional gangue crushing, two-stage crushing is adopted, which is not economic for gangue bricking company. Additionally, there are many problems such as complex craft lines and hard distribution of craft. Liming gangue crusher solved this problem totally with the one stage crushing replacing the traditional two-stage crushing. Liming gangue crusher has a high performance with a long life usage of key resistant material (hammer) than normal hammer. What’s more, the examination and repair is very simple, for example, one person can check the whole machine in 20 minutes. Lower the cost for customer and higher the profits.
