Engineering Review for Replacement Cloth on ANDRITZ / DELKOR / FLSmidth Horizontal Vacuum Belt Filters
Replacement filter cloth — endless belts with clipper or PAD seams — for ANDRITZ, DELKOR (TAKRAF) and FLSmidth (EIMCO) horizontal vacuum belt filters.
Independent replacement cloth — not an OEM spare part. Dimensions and construction are confirmed per enquiry.
How these machines work
Same family, three badges
All three are rubber-belt horizontal vacuum belt filters. The cloth rides on a grooved rubber transporter belt that carries the vacuum through its drainage grooves; the cloth holds the cake and passes filtrate. It runs continuously, so the loads that matter to the cloth are at the joint and along the edges — the joint is pulled every pass, and the edges work against the vacuum seal. The FLSmidth side of the family carries the EIMCO Extractor heritage, which is why older plants still refer to the machine by that name. Machine selection parameters are the OEM's ground, not ours.
Role of the cloth
Why belts come off
- Wear, blinding and joint failure are the three reasons for a change-out. Start from the symptom: seam / joint failure or belt tracking.
- Cloth form on these machines — Endless belt, clipper / PAD, edge seal. The joint type is dictated by the machine, not by preference.
- The weave, polymer and finish language lives on the product page. This page is about fitting your machine.
Key dimensions and duty
Published figures, per machine
The rows naming a machine show the machine makers' own published figures; the remaining rows are not OEM figures. Company-stated numbers are not independent surveys and we do not present them as ours.
| Machine | Size |
|---|---|
| ANDRITZ Delkor HVBF | Large plant units |
| TAKRAF DELKOR HBF | 1–162 m² site claim |
| FLSmidth EIMCO Extractor | Up to ~257 m² heritage |
| Family reference | Belt widths commonly up to 4.5–4.8 m |
| Our mill — maximum width and length | Not yet confirmed in writing; confirmed per RFQ against your drawing |
Replacement route
Third-party replacement is the normal state of this market
On these machines the cloth already comes from more than one source. ANDRITZ machines are listed by independent cloth suppliers; on the FLSmidth side, third-party belt cloth is documented in the trade press at plant scale. That is the market this page sits in — we are one of the weavers in it, and we do not dress that up as an official channel.

Send dimensions and photos
Belt width and length, the seam type your machine runs, and a photo of the old cloth and its joint. A nameplate photo covers the brand and model.

Dimensions and construction confirmed
Dimensions and construction are confirmed per enquiry, including the joint type the machine already uses — clipper or PAD — and the edge treatment.

Check, pack, ship
Checked against the agreed specification before packing, then export crating labelled with your machine reference. Test methods and rigs are not yet confirmed in writing.
What we will and will not say. Brand names are used only to identify machine models; whether a cloth fits a machine is confirmed in writing for each enquiry. We do not claim blanket
interchangeability, OEM spare-part status, or a cloth life in months —
belt life depends on your slurry, your vacuum and your washing, and none of that is ours to promise.

Straight answers
Two questions buyers ask first
Are you an OEM supplier for ANDRITZ, DELKOR or FLSmidth?
No, and we will not imply otherwise. The OEM names on this page identify the machine — nothing more.
What if I do not know the model?
Send it as unknown. A nameplate photo, the belt width, and a photo of the old cloth and its seam are enough to start. The model number is a shortcut to those dimensions, not a replacement for them.
What we need from you
Brand + model + width + seam photo
- Machine brand — ANDRITZ, DELKOR (TAKRAF) or FLSmidth (EIMCO)
- Machine model, or the nameplate photo if the model is unclear
- Belt width
- Belt length
- A photo of the old cloth and its seam
Engineering RFQ
Request Engineering Review
The form opens with ANDRITZ Delkor selected as the machine brand — change it if your machine is a TAKRAF DELKOR or an FLSmidth EIMCO. Add the dimensions and the photos and an engineer picks it up from there.
Sample availability, size, freight and lead time are confirmed per request.
