SED-200LYPT-T pressure melt-cooling spray granulation tower (tower inner shell Φ2 m × H12 m). Designed for low-melting-point materials (40–50 °C) to prevent transit caking. The melt is heated to its melting point, pressu
Funktionsweise
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).
