The twin-shaft dust humidifier, also known as the twin-shaft dust humidifying mixer, utilizes two sets of spiral blades for mixing, offering high mixing efficiency and minimal floor space. The spiral blades are made of special alloy or composite ceramic that is resistant to wear, ensuring a long service life. The twin-shaft dust humidifying mixer is driven by a cycloidal pinwheel reducer for smooth operation and low noise. The mixer feeds from the top and discharges from the bottom, featuring a rational structure. The tight seals between the mating surfaces of the twin-shaft dust humidifying mixer ensure smooth operation. The mixer is equipped with a humidification spray system, providing even water distribution and adjustable water supply to meet requirements. The twin-shaft dust humidifying mixer uses a manual hydraulic pump for centralized lubrication of the four drive bearings, facilitating easy equipment operation and maintenance. The twin-shaft dust humidifying mixer is a device used for spraying water, mixing, and blending powdered materials.
