Coal gangue, as a solid waste in the coal mining industry, not only pollutes the environment when randomly piled up but also occupies land resources. However, coal gangue, which may seem like "waste," can actually be put to good use. The coal gangue crusher can crush, sand, and screen the coal gangue, transforming it into various particle sizes such as 0-5-10-20-30mm. After professional processing with dedicated coal gangue crushing equipment, the solid waste coal gangue can be utilized in different industries.
Here are some applications of solid waste coal gangue:
Road construction: Crushed coal gangue has excellent resistance to wind and rain erosion, making it an ideal material for road construction. Currently, the selling price of road construction materials made from solid waste coal gangue can reach around 70-80 USD per ton.
Brick making: When producing bricks, it is only necessary to crush the coal gangue to a particle size of around 5-10mm. After firing, the selling price of standard bricks can reach around 3,000 USD for ten thousand bricks, with a profit margin of over 65%.
Lightweight aggregate: Lightweight aggregate is a new type of construction material used in large-span bridges and high-rise buildings. Currently, the selling price of solid waste coal gangue as a lightweight aggregate is generally above 90 USD per ton.
In addition, crushed solid waste coal gangue can also be used to produce cement mixtures, silicate cement, chemical mixing materials, and more.
I recommend a vertical composite crusher for crushing coal gangue:
The PFL series vertical composite crusher is a new type of fine crushing and coarse grinding product optimized and developed by our company, combining similar crusher technologies from both domestic and international sources, as well as our years of practical experience. This product utilizes both impact and grinding crushing mechanisms, and our company has led the drafting of the national industry standard for this product. The series can achieve more crushing and less grinding, making it an ideal energy-saving and consumption-reducing fine crushing device.
Feed particle size: ≤240mm
Production capacity: 8~200t/h
Applicable materials: Suitable for crushing medium-hard ores such as medium-soft iron ore, sandstone, gypsum, blast furnace slag, coal gangue, chunk coal, and metallurgical solvent raw materials.
