Application of Hong Cheng Vertical mill in the comprehensive utilization of coal gangue

Coal gangue is one of the largest industrial solid wastes missioned in China. It is a kind of waste residue produced in coal production, accounting for 10% of coal output. Accumulated more than 2.7 billion tons of coal gangue over those years, and continues to increase. Such a startling figures tell us that the comprehensive utilization of coal gangue trend should be carried out without delay, Guilin Hong Cheng Coal vertical mill is widely used in the field, is an advanced milling production line, and is the advanced equipment to boost the comprehensive utilization of coal gangue.3

First, the environmental hazards causes from coal gangue

1. Affect the use of land resources

2. Air pollution

3. Water and soil pollution

4. Landslides and debris flow

Second, the comprehensive utilization of coal gangue

The comprehensive utilization of coal gangue trend is more and more obvious, whether it is for the public welfare point of view, or individual or social market value. In terms of the need to accelerate the pace of comprehensive utilization of coal gangue to improve the existing production and technology use level, research and broaden the application areas of coal gangue, boost the comprehensive utilization of coal gangue development.

Third, vertical mill used in coal gangue

Because of the advantages of high output, low energy consumption, low noise, obvious technological advantages, simple technological process and high efficiency, Guilin Hong Cheng Vertical Mill has a great influence on the application field of coal gangue. More and more coal gangue mills can turn waste into treasure, to achieve comprehensive utilization of coal gangue.
