Vertical dust humidification mixer is the powder material spraying water mixing, mixing efficient equipment. By controlling the amount of water has reached the appropriate moderate requirements. Mainly used in thermal power plant dust, dust humidifying machine is also available in metallurgy, mining, building materials, chemical industry, power plants, boilers and other industries for dust and powder materials for humidification and conveyed to a treatment program, effectively preventing flying dust and powder materials produced in the process of handling and transportation. Avoid environmental pollution of the necessary equipment. Dust humidifier works: precipitator dust collected by star dust discharge valve into the body of the auger blade, the auger into the main tube humidification stir in spirochetes uniform mixing, water spray uniformly injected into the material under constant agitation of the role of the dust humidification, dust after humidification under thrust more linear spiral column from the discharge port slowly sent, unloaded into dust transport device outside the body. When uniform spiral body motion, vibration apparatus intermittent work, so that the circumferential wall of the cylinder and other spices oscillation amplitude, the viscosity of the metal powder after humidification from the cylinder wall, to the discharge port is completely discharged. Products are divided into three series: Single dust humidifier, humidifier biaxial dust, dust humidifier vertical, horizontal dust humidifier. For different materials, different environmental conditions, can choose different dust humidifier.
