Fonctionnement

Melt feed from upstream reactor -> insulated plunger pump (3DP-20, 2.2 kW, 0–16 MPa) + filter -> steam/oil-jacketed pressure spray gun with tungsten-carbide nozzle plate (adjustable swirl aperture) -> droplets atomised into downward-flow cooling tower (Φ2 m × H12 m, inner wall SUS304 2.5 mm, 60° cone bottom, star-valve discharge) -> chilled air from supply fan (4-72, 5.5 kW) flows down through inverted-cone air distributor at tower top -> droplets solidified into 1–2 mm granules collected at cone bottom -> fine powder/exhaust exits via central duct to pulse baghouse (72 × Φ120×2000 mm filter bags) -> clean air drawn by induced-draft fan (9-26, 18.5 kW) -> passes through SRZ-17×7D steel-pipe spiral aluminium-fin heat exchanger (400 m²) for re-cooling -> recirculated (closed-loop with nitrogen) or exhausted (open-loop).

Matériaux du bâti

SUS304 inner wall + Q235 outer wall (0.6 mm); 80 mm rockwool insulation; fans and air ducting in Q235; heat exchanger Q235/aluminium fins

Caractéristiques principales

Tower inner shell Φ2 m × H12 m, SUS304 2.5 mm inner wall, polished

60° cone bottom with star (rotary airlock) valve for continuous discharge (0.75 kW)

Pressure spray gun with steam/oil-heated jacket and tungsten-carbide swirl-plate nozzle

Inverted-cone air distributor and spray-head safety hood at tower top

5 × SK60 pneumatic knockers on cone wall (requires ≥4 kg/cm² compressed air)

XF700 cyclone separator (SUS304) for pre-separation

72-bag pulse baghouse (YMC-72) for fine powder collection (SUS304)

SRZ-17×7D 400 m² steel-pipe spiral aluminium-fin air cooler

Supply fan 4-72 (5.5 kW) + induced-draft fan 9-26 (18.5 kW)

Negative-pressure operation prevents dust leakage

Suitable for heat-sensitive materials (vertical mixed-flow: counter-flow then co-flow)

Uniform 1–2 mm granule particle size — adjustable via swirl plate aperture

All product-contact surfaces SUS304 (piping, valves, nozzle, cyclone, baghouse, discharge valve)

Negative-pressure operation eliminates dust leakage

Suitable for heat-sensitive active ingredients — vertical mixed-flow design preserves activity

Optional nitrogen-protected closed-loop or open-cycle configuration

Applications

Spray granulation of low-melting-point materials (40–50 °C)

Heat-sensitive material cooling and granulation

Free-flowing granule production (1–2 mm particle size)
