The twin-axis dust humidifier, also known as the twin-axis dust humidifying mixer, uses two sets of spiral blades for mixing, featuring high mixing efficiency, minimal land area requirement, and spiral blades made of wear-resistant special alloys or composite ceramics, with a long service life. The twin-axis dust humidifying mixer (dust humidifier) is driven by a cycloidal pinwheel reducer, ensuring smooth rotation and low noise. The twin-axis mixer feeds from the top and discharges from the bottom, with a reasonable structure. The twin-axis dust humidifying mixer (dust humidifier) has tight seals between mating surfaces, operates smoothly, and is equipped with a humidification spray system that provides even water distribution, allowing for adjustable water supply to meet requirements. The twin-axis dust humidifying mixer (dust humidifier) utilizes a hand-pumped oil supply to centrally lubricate the four transmission bearings, making equipment usage and maintenance convenient. The twin-axis dust humidifying mixer (dust humidifier) is a device for spraying water, mixing, and blending powdered materials.
