What Is an SJ Humidifying Mixer?
The SJ Humidifying Mixer is an advanced dual-shaft industrial mixer that specially engineered by Hebei OuTai Environmental Protection Equipment Co., Ltd. – Senotay who are a chinese manufacturer. The humidifying mixer Designed to handle a wide range of powder and ash materials and this mixer efficiently combines dry particulate matter such as like fly ash, slag or dust with water to create a non-dispersible slurry.
Unlike conventional powder mixers the SJ Series combines humidifying and mixing in one continuous process, effectively reducing airborne dust by over 95%, making it an ideal solution for cement plants, thermal power facilities, steel manufacturing and mining operations.
The cause of Choosing SJ Humidifying Mixer
Industrial operations are increasingly challenged by fugitive dust emissions that directly put impact air quality and worker safety. The SJ Humidifying Mixer delivers a proven dust suppression solution that ensures compliance with both China’s GB 16297-1996 and EU IED 2010/75/EU standards.
Here some reason why industries trust the SJ Series:
IT have ability Up to 95% dust emission reduction after mixing.
It can Moisture uniformity within ±1.5% which ensuring precise conditioning.
The mixer have High durability with Cr26Mo2 wear-resistant liners for a 3–5× longer lifespan.
It is specially Designed for harsh industries like mining, cement and waste management.

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.
