The Numbers That Stay Fixed

Across all three product pages, the WL series table is identical. The published reference line configurations:

The WL-2000 row reads the same everywhere: 2,000-3,000 kg/h of capacity, 8-12 t/h of water, 180-250 kW installed, and outlet moisture at 2% or lower after drying. The water figure sits mid-series too — the published range runs from 3-5 t/h on WL-500 to 12-20 t/h on WL-5000, all closed-loop, with settling, filtration and water treatment included. What the table deliberately does not tell you is how those kilowatts are spent — and that is the part that changes with the feed.

Film Feed: Sizing by Wet Throughput

On the film page, the WL-2000 is the agricultural-film and stretch-film configuration, and the page attaches a warning that changes how the capacity column should be read: film lines are usually sized by wet throughput, which is lower than the dry figure for the same model. Because film's bulk density is low, the published FAQ spells out the consequence — the same model handles fewer kilograms of film per hour than of rigid scrap. The 2,000-3,000 kg/h figure is a rigid-scrap number until a material trial says otherwise for your film.

The process route is also its own. Film wraps around shafts and floats instead of sinking, so the published sequence starts with a bale opener that loosens bales without tearing the film into unfeedable tangles, followed by anti-wrapping controlled conveying. Size reduction happens in water, which keeps the film moving and starts soil removal at the same moment. From there the route runs through intensive friction washing, mechanical squeezing to remove the bulk of the water, and thermal drying before densifying or granulation. Our earlier post on wet throughput and squeezing covers how that sizing arithmetic works in detail.

Bottle Feed: Dwell Time Before Tonnage

The PET page describes the WL-2000 as a regional bottle recovery line, and adds the most quoted note in the series: PET projects normally sit on WL-1000 and above so the hot-wash stage has enough dwell time. That is a different sizing logic from film. On bottles, the constraint is not bulk density but the time flakes spend in the heated wash liquor with dosing — the stage that removes glue and organic residue. Undersize the line and the hot wash gets rushed; the contamination the whole line exists to remove survives the bath.

The published PET sequence is de-baling, de-labeling before crushing, PS-series crushing, hot washing, density separation and dewatering/drying. Two of those stages exist because of what PET carries: paper and film labels, glue residue, caps and rings, sand, organic residue and metal. De-labeling before crushing is what keeps glue out of the wash bath — our post on label removal before washing explains why the order is not negotiable. Density separation then floats off the caps and rings (PP/PE fractions) while the heavier PET sinks. Colour, the page notes, is a separate sorting decision — the washing line removes contamination; colour and polymer sorting are configured to the target output.

Mixed Rigid Feed: The Crossover Configuration

The PP/PE rigid page gives the WL-2000 its broadest description — mixed rigid and film plastics — and the most general sizing note: final sizing is confirmed after a material study. Rigid PP and HDPE share the same published process route, with separation and drying settings adjusted to the mix: feed metering, PS-series crushing, high-speed friction washing that strips soil, labels and residue, float-sink separation that drops out sinks such as metal, stone and heavy plastics, then dewatering and drying.

This is the route where the front end earns its keep, because "mixed rigid and film" means the line must survive both behaviours. Rigid scrap wants the aggressive route; film wants anti-wrapping handling, which is why the page's equipment list includes a single shaft shredder alongside the PS-series crusher — pre-shredding opens bags and loosens film before the crusher sees them. The ratio between rigid and film in your feed decides how much of the film-specific front end the line carries. Our stage-by-stage walkthrough of the PP/PE rigid washing line covers what each stage removes.

Reading the Table the Way It Is Meant

Three published phrases sit under the tables on these pages and they matter more than any single row: "reference line configurations", "figures are the values published for the LVKE washing-line series", and "final sizing is confirmed after a material study". The table is a starting grid, not a promise. Two buyers can both order a WL-2000 and receive different lines — one with a heavier pre-wash for soil-laden agricultural film, one with the hot-wash dwell time a bottle-to-flake specification demands, one with the float-sink and friction washing balance a mixed rigid stream needs.

The constants are the published ones: the capacity band, the water band, the power band and the 2% or lower outlet moisture, reached through mechanical dewatering followed by thermal drying. Everything else — stage count, machine selection, settings — follows the feed. That is why the enquiry asks for material form and contamination, not just tonnage: the same question that separates the three pages' descriptions of one model.

What to Send With the Enquiry

The three pages converge on the same invitation, phrased for their own feed. Translated into a single checklist, a WL-2000 enquiry is answered well when it includes:

• The feed mix — which of the three personalities you are closest to: film, bottles, or mixed rigid with a film fraction.
• Contamination — soil load, label type, glue, caps and rings, metal; the stages exist to remove specific fractions.
• The target output — flake quality the downstream granulator or end user accepts, including moisture.
• Bale photos or a sample — the basis for the material study or wash trial that confirms final sizing.

Figures beyond the published series are confirmed per project after that trial — the tables are the reference, the material is the decision. To route the enquiry to the right engineering desk, name the feed personality first: the film line, bottle line and rigid line teams each start from a different default configuration of the same model.
