Chemical Powder Centrifugal Spray Dryer Machine LPG150-C Industrial Drying

The LPG150-C Chemical Powder High-Efficiency Centrifugal Spray Dryer represents a purpose-engineered solution for the demanding chemical processing industry. Constructed with 316SS anti-corrosion stainless steel throughout the entire material pathway, this industrial drying system handles aggressive chemical slurries, catalyst precursors, pigment dispersions, and detergent formulations with exceptional reliability. The unit achieves 150-200 kg/h water evaporation capacity through an optimized hot air distribution system that ensures uniform droplet-to-particle conversion while maintaining precise temperature gradients essential for heat-sensitive chemical compounds.

• 316SS Anti-Corrosion Construction: Complete material contact zone fabricated from 316SS stainless steel with electropolished surface finish, providing superior resistance to acidic, alkaline, and chloride-containing chemical feedstocks.
• Three-Stage Dust Recovery System: Primary high-efficiency cyclone achieves 95% separation, secondary diffusion cyclone boosts recovery to 97-98%, and tertiary water film scrubber captures sub-micron particles at >99.5% efficiency while neutralizing exhaust gases.
• Variable Frequency Atomization: High-speed centrifugal atomizer with stepless frequency regulation allows real-time adjustment of rotational speed from 8000 to 18000 r.p.m, enabling precise control over mean particle size distribution across diverse chemical formulations.
• Multi-Source Heating Flexibility: Configurable heat source options including steam plus electric compensation, direct gas-fired, thermal oil, or hot air furnace systems accommodate varying site utility availability and operational cost requirements.
• Intelligent Fuzzy Control Architecture: PLC controller with touch-screen HMI builds real-time mathematical models correlating inlet temperature, feed rate, and atomizer speed, automatically compensating for feed viscosity fluctuations to maintain ±2°C outlet stability.
• Anti-Bridging Pneumatic System: Three independent pneumatic hammers mounted on the cone section deliver intermittent percussive force, dislodging any powder accumulation and ensuring continuous free-flow discharge through the star-type rotary valve.
• Smooth-Flow Interior Geometry: All internal transitions utilize large-radius arc or planar intersections with grinding and polishing beyond Ra 0.8μm, eliminating material hang-up points and facilitating complete product changeover between chemical batches.

The LPG150-C excels in chemical manufacturing environments where corrosion resistance and consistent powder morphology are critical. Primary applications include spray drying of inorganic pigments and colorants, ceramic precursor powders, polycarboxylate water reducers, detergent enzyme granules, polymer resin emulsions, silica and alumina catalyst supports, flame retardant additives, and precipitated calcium carbonate. The unit also handles organic chemical intermediates, agrochemical formulations including wettable powders and water-dispersible granules, and specialty plastic additives. The flexible heating configuration allows processing of both aqueous and solvent-based feed systems with appropriate explosion-proof modifications, making this dryer adaptable across fine chemical, petrochemical derivative, and industrial mineral processing operations.

Every LPG150-C spray drying system undergoes rigorous pre-delivery inspection including hydrostatic pressure testing of all process vessels, electrical continuity and insulation resistance verification, PLC logic sequence validation, and full-load trial operation using water as process fluid. The disassembled modules are individually wrapped in VCI anti-corrosion film, sealed in heavy-gauge polyethylene, and packed in ISPM 15 certified fumigated wooden crates with shock-absorbing foam inserts for sensitive instrumentation. Each shipment includes a complete documentation set comprising GA drawings, P&ID diagrams, electrical schematics, material test certificates, weld procedure specifications, and surface roughness measurement reports. Post-installation services include on-site commissioning by factory-trained engineers, comprehensive operator training, and process optimization assistance. Standard warranty covers 12 months operational or 18 months from shipment for all non-consumable components.
