Efficient pulverized coal industrial boilers refers to the new coal-fired industrial boilers which take "coal combustion technology" as the core. Coal will be pulverized to 150-200 mesh fineness and then sent into the boiler for combustion. In the grinding process, the impurities are removed sufficiently.The coal has fine particles, easy to ignite and can improve the burnout rate.

 

In the boiler pulverized coal production, Kefid developed VM vertical mill which specifically for the boiler pulverized coal preparation, suitable for anthracite, bituminous coal and lignite. The system sets crushing, drying, grinding, grading conveyor in one. The form of drying and grinding two in one achieve grinding and drying "one-step"  process. The large-scale mill's on-line CO-O2 analysis system, the grinding roller hydraulic device and the automatic electronic control device make the grinding process more smarter and more efficient.

 

At the same time, in view of the particularity of pulverized coal processing, Kefid vertical mill adopts nitrogen inerting technology in the process of pulverizing coal and three-stage explosion-proof device, the system safety is greatly improved. It also equipped with environmental dust and noise reduction devices to meet environmental production standards and have received customer satisfaction feedback.
