Against the backdrop of industrial powder upgrading, Coal-water slurry The quality of its preparation directly affects the thermal efficiency of combustion. As the core, Vertical Stirring Mill (Also known as Wet Ultrafine Grinding Machine ), leveraging advanced wet-process technology, is emerging as a key enabler for cost reduction and efficiency enhancement in power-plant boilers and chemical gasification applications.

Core mechanism:   This Ultrafine pulverizer A multi-stage alloy turbine disk structure is employed, integrating gravity and fluidization technologies. The pre-treated coal slurry enters the grinding chamber from the bottom of the equipment and, under the action of the high-speed rotating grinding media, undergoes intense impact and shear. This “ Bottom inlet, top outlet ” the continuous processing pathway, ensuring that the coal particle size is precisely refined to 0.5–5 μm 。

Technical and Application Advantages:

Combustion efficiency range:   After Ultra-fine grinder The burnout rate of processed coal particles has exceeded 98% , compared with loose coal, an increase 20%  Above, coal consumption is reduced at the same calorific value. 10%-15% 。

Deep performance optimization:   Effectively addresses the pain points of conventional grinding equipment, such as uneven fineness, high energy consumption, and poor stability, while significantly reducing wear on downstream nozzles.

Green and low-carbon value:   By enhancing carbon conversion efficiency, we help industrial kilns achieve ultra-low emissions during the transition from oil and gas to alternative fuels.
