Product Overview

Our double shaft industrial humidifier, also widely known as fly ash humidifier and bulk material wet mixing machine, is professional heavy-duty industrial dust suppression & material conditioning equipment mainly applied in thermal power plant ash conveying system, flue gas desulfurization project, cement plant, mine and solid waste disposal industries. This twin-shaft mixing humidifier mixes dry fly ash, powder ash and bulk dusty materials evenly with atomized water inside the sealed tank body, perfectly solving the problem of dust flying during ash unloading and material transportation. As a core environmental protection device for dust suppression and ash humidification, it can stably control material moisture, eliminate secondary dust pollution, and help enterprises meet environmental emission standards.

Main Structural Features

1. Dual Opposite Rotation Mixing Shaft System Equipped with two parallel stirring shafts rotating reversely, fitted with wear-resistant alloy mixing blades. The double-shaft stirring structure brings powerful rolling and shearing mixing effect, no mixing dead angle, so powder materials and water mist can be fully blended. The blades have strong abrasion resistance, greatly extending the service life of this ash humidifier.
2. Fully Sealed Box Housing Thickened carbon steel sealed tank design, completely avoiding dust leakage in working process. Compared with open-type mixing equipment, this industrial dust humidifier achieves zero outward dust overflow, suitable for enclosed workshop and outdoor environmental protection construction conditions.
3. Precision Atomized Water Spraying Mechanism Multiple groups of high-pressure atomizing nozzles are arranged on the top of the equipment. Water is sprayed into tiny water mist to fully combine with dry ash materials, realizing uniform humidification without material caking. The water inlet pipeline supports flow adjustment, which can flexibly match the humidification demand of different material output.
4. Stable Drive & Maintenance-Friendly Configuration Adopts reducer + motor integrated drive unit, stable operation with low noise and low failure rate. The side-mounted electric control cabinet is convenient for circuit inspection and operation control. The whole machine is fixed on an integrated base frame, convenient for container packaging, sea freight transportation and on-site installation for overseas projects in Singapore, Southeast Asia and other regions.
