The twin-axis dust humidifier, also known as the twin-axis dust humidifying mixer, utilizes two sets of spiral blades for mixing, featuring high mixing efficiency, minimal floor space, and blades made of wear-resistant special alloy or composite ceramic for extended service life. The twin-axis dust humidifying mixer (dust humidifier) employs a cycloidal pinwheel reducer for transmission, ensuring smooth operation 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 all mating surfaces for stable operation. It is equipped with a humidification water spray system, providing even water distribution, and the water supply can be adjusted to meet requirements. The twin-axis dust humidifying mixer (dust humidifier) uses a hand-pumped oil supply to centrally lubricate the four transmission bearings, making the equipment easy to use and maintain. The twin-axis dust humidifying mixer (dust humidifier) is a device for spraying water and mixing, as well as blending powdered materials.
