Lanhao Fluidization Disc (Fluidization Plate) DN600-1200 is a fluidization device specifically designed for large powder silos, suitable for ultra-dense phase pneumatic conveying systems in industries such as power plants and metallurgy. Below is a summary of comprehensive technical parameters and application features:
I. Core Specifications and Structure
Model and Dimensions
Covers specifications from DN600 to DN1200. The main body is made of sintered stainless steel mesh or canvas permeable layer, fixed to the silo body via annular grooves through welding.

Connection methods support flanges (PN1.6 pressure rating) or direct welding, compatible with large silo pumps and homogenization silos.
Fluidization Principle
High-pressure gas (0.05-1.0MPa) penetrates the permeable layer, causing powdered materials to enter a gaseous state, improving fluidity by over 50%.
The internal canvas is precisely bonded to rectangular protrusions to prevent material backflow, extending service life by three times compared to traditional silicon carbide plates.

II. Typical Application Scenarios
Power Plant Dry Ash Conveying: Installed at the bottom of silo pumps to promote uniform fluidization of pulverized coal and fly ash, replacing screw conveyor methods.
Cement Homogenization Silos: Used in raw material aeration boxes to achieve high-precision mixing and reduce the risk of clumping.
III. Technical Advantages Comparison
Feature Traditional Fluidization Plate Lanhao Fluidization Disc (DN600+)
Permeability Uniformity Prone to Local Blockages Canvas/Sintered Mesh Full-Area Permeability
Maintenance Cost Frequent Replacement Required Maintenance-Free Design
Applicable Scale Small to Medium Silos Large Silo Pumps/Homogenization Silos
IV. Selection Recommendations
Material Selection: For corrosive environments, prioritize 316L sintered stainless steel mesh; for conventional conditions, canvas permeable layers can be chosen.

Installation Requirements: Must be paired with filtration and pressure regulation units. Recommended pressure: 0.3-0.6MPa; installation spacing ≤2m.
Note: Specific parameters should be determined based on material characteristics (e.g., particle size, humidity) and silo structure design.
