Coal dust formation and hazards

Introduction to coal dust

Coal dust is formed during the processing, transportation and combustion of coal. The particle size formed is 0.1~1000 microns. According to the size of the particle, coal dust is divided into three categories: coarse coal dust, medium coal dust and fine coal dust. The particle size of coarse coal dust is 10~1000 microns, the particle size of medium coal dust is 1~10 microns, and the particle size of fine coal dust is 0.1~1 micron. Coal dust may cause pneumonia, pulmonary mycosis and other diseases. Therefore, pollution indicators in the workplace are also controlled by regulatory agencies. If the hygiene requirements are not met, environmental protection fines will be faced.

Coal dust formation

The process of coal mining, processing and transportation of coal by coal mining enterprises will lead to the release of a large amount of coal dust.

Power plants that burn coal to generate electricity may become a source of coal dust pollution. In the process of burning coal, coal particles and other emissions are released into the atmosphere. Metallurgical enterprises that use coal as fuel or raw material may release a large amount of pollutants when metallurgical enterprises process and burn coal. Coal is used as a heat source in the cement chemical production process, and a large amount of coal dust will also appear in the air during production. Therefore, controlling and reducing industrial emissions is an important task to protect the environment and human health.

Coal dust characteristics and hazards

From a physical point of view, coal dust particles are very small, with a large specific surface area, strong adsorption capacity and high activity. When coal dust particles enter the respiratory system, they can cause diseases such as pneumoconiosis, seriously affecting the health of workers. In addition, coal dust has certain explosive characteristics. When it reaches a certain concentration, it will cause an explosion accident when it encounters a fire source. Therefore, the monitoring and supervision of coal dust is very important.

Coal dust control

In order to reduce the damage of coal dust to human health and the environment, it is urgent to control and manage coal dust. Commonly used coal dust control methods include wet spray, fog cannon spray, photocatalyst, electrostatic dust removal, etc. In addition, strengthening the transportation management of coal and improving the production process are also effective measures to reduce the generation of coal dust.

Coal mill

In order to reduce the generation of coal dust in the generation process of coal enterprises, Xingaonai Heavy Industry has focused on designing a coal mill, which is designed for coal and coal powder. The fireproof and dustproof mill room protects the unsafe factors generated during coal grinding and production. The coal mill has been highly praised by a large number of coal enterprises, achieving safe and efficient production at a cost-effective price.

Thanks to the success of engineers from Xingaonai Heavy Industry, the coal mill has been exported to the global market and successfully obtained quality certificates (ISO international quality system certificate, EU CE certificate and Russian GOST certificate).
