Shandong Jinglan produces fluidizers for tank bottoms, which are key flow aid devices in powder material handling systems. They are primarily used to address issues such as material bridging and arching during silo discharge. Their core functions and technical features are as follows:
1. Definition and Working Principle
Basic Definition
A fluidizer is a flow aid component installed at the bottom of powder silos (such as ash hoppers or blow tanks). It fluidizes the powder by introducing compressed air, thereby enhancing material flowability.
Working Principle
Compressed air uniformly penetrates the powder layer through the fluidizing plate (porous permeable layer), reducing friction between the material and the silo wall and disrupting the accumulation structure.

Some models incorporate high-frequency vibration (e.g., silo fluidizers) to further prevent material moisture absorption and hardening.
2. Core Structure and Technical Characteristics
Core Components
Fluidizing Plate: Typically made of sintered stainless steel mesh (e.g., SUS316L/304) or multi-layer metal woven mesh, featuring high-temperature resistance (-220–480°C), corrosion resistance, uniform porosity, and high mechanical strength.
Sealing Structure: Equipped with elastic seals (e.g., silicone pads) or sealing adhesive layers at the edges to prevent gas leakage.

Performance Advantages
Fluidization Effect: Uniform air distribution significantly enhances powder suspension flowability, forming a solid-gas mixed state suitable for pneumatic conveying.
Interference Resistance: The high-frequency vibration design is unaffected by material moisture and is equally effective for adhesive powders (e.g., coal powder, desulfurization ash).
Energy-Saving Feature: Optimizes gas utilization, reducing conveying energy consumption by 20–30%.
