300,000TPY Clean Coal Grinding Line

Project Background

Since 2015, the air pollution has been a headache in northern China. Coal combustion deepens the environment pollution and damage of ecosystems because of a great deal of emission of dust, SO2 and nitric oxides. For coal combustion, both the thermal power plant and industrial coal-fired boiler are the two main application fields.

So, in 2015, China National Energy Bureau launched the Action Plan of Efficient& Clean Use of Coal (2015-2020) and required every province to boost the transformation and upgrading of industrial coal-fired boilers. Meanwhile, release and revise of some other related policies stipulated the responsibility of government on environment protection and punishments once there is some company trying to discharge pollutants at random.

In response to environmental protection, this customer has been adjusting its operation structure in recent years and started to march to the market of clean coal powder.

Design Scheme

Project Site: Gansu, China

Equipment: 1 LM220 Vertical Mill, dust collector, fan, nitrogen protection system, fire extinguishing device and intelligent centralized control device

Material: Coal Input Size: ≤40mm

Output Size: 200meshes (0.074mm), D80


Technological Verification

Efficient industrial coal powder boiler is the new energy saving technology which supported strongly by China. Based on the absorption of advanced foreign technologies, the efficient coal powder boiler has been developed by China Coal Research Institute. The new boiler can save coal by 30% and reduce dust emission by 95%. The emission of SO2 is one ninth of the national standard. The coal ash formed can be cycled as building material so that the problems of waste gas and residues can be avoided.

Configuration Of Production Line

Considering the actual situations, we recommended our vertical mill to the customer. And the efficient coal powder preparation system we customized mainly consists of coal pre-homogenization system, coal conveying system, grinding system, hot-air system and anti-explosion system, etc.
