A washing line is a sequence of problems solved in order. Each stage removes a specific kind of contamination, and the equipment at that stage is chosen to suit it.
The process, stage by stage
1. Feeding and conveying
Material is loaded onto a belt conveyor or elevator that meters it into the crusher at a steady rate. Uneven feeding is one of the most common causes of inconsistent output further down the line, so the conveyor is sized to the crusher’s appetite rather than to the operator’s convenience.
2. Crushing and granulating
The crusher reduces the material to flakes of a controlled size. Rotor geometry and screen aperture are chosen for the stock: film and woven bag need a different cutting action from thick pipe or crates. Blades are replaceable and can be re-ground on our own blade grinder, which keeps the machine cutting rather than tearing.
3. Friction washing
The friction washer subjects the flakes to high-shear scrubbing against a perforated drum. This is where soil, oil and heavy surface contamination come off. Water is fed through continuously and the drum is sized so the material spends long enough inside to be cleaned, without the throughput dropping.
4. Rinsing and separation
Rinsing pools and washing tanks flush away the loosened dirt. Separation happens here too: label paper and light film float while denser plastics sink, magnetic separators pull out metal, and air separators divide material by weight. This is the stage that determines the purity — and therefore the resale value — of the finished flake.
5. Dewatering and drying
A high-speed dryer removes surface moisture mechanically. Lower residual moisture means a higher price from the buyer and fewer problems if the material is stored before sale.
6. Discharge and collection
The finished flake is conveyed out to a collection point or directly into a baler or silo. Conveying is matched to the dryer’s output so the line runs continuously rather than in bursts.
Engineering principles we hold to
Sized against your material, not a catalogue
Throughput figures depend heavily on bulk density, contamination and the form of the input. We size from the material you actually run, which is why a sample or good photographs matter more than a specification sheet.
Water and power consumption
Rinsing water is recirculated through the pools rather than used once and discarded, which cuts both consumption and discharge. Motors are selected for the duty cycle the machine actually sees, not the peak figure on a sales sheet.
Wear parts designed to be replaced
Blades, screens, liners and pump components are treated as consumables and made accessible. A machine that can be maintained on site keeps running; one that cannot becomes a bottleneck.
Simple structures
We avoid unnecessary complexity. Fewer mechanisms mean fewer failure points and a machine that a customer’s own maintenance team can strip, service and reassemble without specialist tools.
