Centrifugal Galvanizing
In modern industrial galvanizing plants, achieving a consistent, high-quality zinc coating on small to medium-sized components requires more than just immersion in a hot zinc bath. The ANI Metal Centrifugal Galvanizing System combines precise thermal control with high-speed rotation to remove excess zinc and deliver uniform, drip-free finishes—boosting throughput, reducing waste, and elevating overall plant efficiency.
ANI METAL, as one of the leading plant suppliers in the hot dip galvanizing industry, in addition to the supply of turnkey galvanizing plants.
How Centrifugal Galvanizing Works
Immersion Phase
Parts are lowered into the hot-dip galvanizing kettle to ensure complete zinc penetration and metallurgical bonding.
Rotation Phase
Immediately after immersion, the system’s turbine-driven basket spins at adjustable speeds (up to 1,200 RPM), flinging off surplus zinc.
Drip Tank Recovery
Separated zinc droplets fall into a dedicated drip tank, where they solidify and are recycled back into the main bath—minimizing material loss.
Cool-Down & Discharge
Components exit the centrifuge fully coated, with a smooth, encapsulating layer free of runs, drips, or irregular thickness.
Key Features of the ANI Metal Centrifugal Galvanizing System
Variable Speed Control
Fine-tune rotation rate to match part geometry and desired coating thickness, ensuring optimal metal protection solutions.
Heavy-Duty Basket Design: Corrosion-resistant stainless steel baskets endure continuous exposure to molten zinc and repeated high-G forces.
Automated Sequence Programming: PLC-driven operation synchronizes immersion time, spin speed, and drip-tank cycles for consistent results and minimal operator intervention.
Integrated Safety Enclosures: Heat-insulated guards and emergency-stop interlocks protect personnel and comply with stringent plant safety regulations.
Modular Footprint: Scalable configurations allow easy integration into both new installations and retrofit projects across varied production capacities.
Operational & Environmental Benefits
Uniform Coating Quality
Eliminates “edge build-up” and uneven film thickness, delivering smooth, defect-free finishes that meet ISO galvanizing standards.
Zinc Savings: Recovers up to 20 % more zinc through efficient drip-tank collection, lowering raw-material costs and waste.
Increased Throughput: Rapid spin-dry cycles reduce total processing time by up to 30 %, boosting plant productivity and on-time delivery.
Reduced Labor: Semi-automated handling cuts manual finishing and cleanup tasks, freeing operators for value-added activities.
Lower Emissions: Controlled zinc recovery and enclosed drip collection help meet environmental permit limits for fume and particulate discharge.
Installation, Maintenance & ROI
The ANI Metal system installs seamlessly alongside existing galvanizing lines. Routine maintenance—such as periodic bearing lubrication and filter-bag inspections—takes less than 30 minutes per week. Most customers realize a full return on investment within 9–12 months thanks to lower zinc consumption, faster cycle times, and reduced rework costs.
