Note 1: The table is split into two application groups, Building-materials dryer and Steel-plant dryer, merged down the Type column; the group name is repeated per row here.

Note 2: The same model Φ3.0x20 appears with opposite inlet-air-temperature direction in the two groups (≤700 vs ≥800); Φ2.4x18 also appears in both groups. Reproduced as printed.

Note 3: The last two rows Φ4.2x32 and Φ5.0x40 (laterite nickel ore) belong to the Steel-plant dryer group in the catalogue, not to a separate group.

Note 4: Moisture is a two-level heading (Initial / Final) and is split into two columns here; the Final column carries bracketed material notes as printed.

Note 5: Inlet air temperature mixes ≤, ≥ and ranges; reproduced as printed.
