Continuous Dust Suppression & Slag Conditioning System
The SJ Series Humidifying Mixer is a heavy-duty, dual-shaft conditioning system engineered to blend dry industrial powders, fly ash, slag, and dust with water into a non-dispersible, transportable slurry. Using dual counter-rotating shafts with staggered high-shear paddles paired with a PLC-controlled liquid atomization spray system, it cuts airborne dust emissions by over 95% while holding moisture uniformity within ±1.5%. Designed for continuous, heavy-duty processing, it prevents fugitive dust during ash handling and transport across thermal power plants, cement mills, mining sites, and steel manufacturing operations.
Core System Advantages
95%+ Fugitive Dust Reduction: Converts fine, dispersible dry ash and slag into a stabilized, non-dusting moist cake for clean open-truck transport or disposal.
PLC Precision Water Dosing: Stainless-steel atomizing nozzles spray micro-droplets (0.1–0.3 mm), maintaining precise moisture control between 8% and 12% with ±1.5% uniformity.
Cr26Mo2 High-Chrome Wear Protection: Replaceable high-chrome alloy liner plates and 42CrMo forged shafts provide 3–5 times the wear life of conventional carbon steel mixers.

SJ Humidifying Mixer Work process
The working mechanism of its involves four precision engineered stages:
Material Infeed: In the material feeding process those dry dust or ash is fed through a volumetric screw conveyor into the sealed mixer chamber.
Dual-Shaft Mixing: Here inside the mixing process is two counter-rotating shafts equipped with staggered paddles generate strong shear forces which intensively agitating dry materials.
Water Injection: For water injection the stainless-steel atomization system sprays micro-droplets (0.1–0.3 mm) uniformly for controlled humidity between 3–8%.
Discharge: The conditioned material is discharged through a sealed outlet for safe handling or landfill deposition.
This process reduces airborne dust, optimizes moisture use by 30%, and ensures continuous, clog-free operation even under heavy-duty loads.
