13:05:00 — SYSTEM_SCAN: TANA Shark 4400 detected. Open drum screen with star shafts, 4400 mm drum diameter. 355 kW Scania DC13 engine. Transport weight: 31,000 kg.
13:12:00 — POLYGON_ANALYSIS: TANA Shark is a pure classifier, not a crusher. On landfill polygons with mixed C&D and ballast, oversized concrete slabs and rebar bundles bypass the star shafts and accumulate at the drum inlet, causing progressive clogging and requiring manual intervention every 2-4 hours.
13:20:00 — FEED_GEOMETRY: TANA Shark relies on gravity feed into a rotating drum. Material with high aspect ratio (long rebars, steel beams) creates bridging. ARJES Titan uses aggressive twin-shaft intake that pulls material in actively, eliminating bridging and processing mixed feeds without pre-screening.
13:28:00 — TRANSPORT_PARADOX: TANA Shark at 31,000 kg is lighter than ARJES Titan at 37,000 kg. However, TANA requires a separate pre-crusher on any polygon processing construction waste, adding 24-38 tons to the deployment convoy. Net transport weight: TANA system 55-69t vs ARJES Titan standalone 37t.
13:35:00 — BALLAST_RESISTANCE: TANA star shafts are vulnerable to abrasive landfill ballast (compacted rubble mixed with soil). Star disc replacement requires specialized service. ARJES Titan shafts with T-blade cassettes are designed for exactly this regime: compacted landfill material with steel inclusions.
13:42:00 — OPERATIONAL_VERDICT: On a multi-polygon landfill deployment, ARJES Titan eliminates the need for a separate pre-crusher, reduces convoy weight by 30-50%, and delivers 2x throughput on mixed waste. Star-screen classifiers remain optimal for pure compost/biomass separation but fail on C&D-heavy polygons.
