HVBF Cloth Spec Sheet
The parameter sheet for horizontal vacuum belt filter cloth. Below is exactly what it contains and which sections are still waiting on confirmed mill values.
What is in the sheet
Nine sections. A status of UNKNOWN means the value exists as a property of the cloth but has not been confirmed in writing by the mill, so it is not printed anywhere yet.
| Section | What it states | Status |
|---|---|---|
| Cloth family and construction | Weave type and polymer options offered for horizontal vacuum belt service, described as a range rather than a single SKU. | Pending mill confirmation |
| Pore size / micron rating | Rating per cloth construction, with the method used to arrive at it stated alongside the figure. | UNKNOWN |
| Air permeability | Permeability per construction, in CFM, with the test pressure and the test method category printed next to every figure. | UNKNOWN |
| Seam options | Drawings of the seam types we fabricate — clipper, PAD, spiral and overlap — with what each one is chosen for. | Drawing set in preparation |
| Width and length range | The widths our looms produce and the endless-belt lengths we fabricate, stated as limits rather than as a claim about your machine. | UNKNOWN |
| Chemical and temperature limits | Resistance envelope per polymer. Where a limit depends on your slurry, the sheet says so instead of printing a single number. | UNKNOWN |
| Edge treatment options | Edge constructions available and which failure mode each one addresses. | Pending mill confirmation |
| Quality checks before shipping | Which checks every belt goes through before it is packed — the test categories are named, without invented standard numbers. | In preparation |
| What we need from you | The machine and old-cloth information required before any value in this sheet can be turned into a quotation. | Written |
Read this sheet if you are doing one of these
Re-specifying a belt that failed early
You need permeability and pore rating side by side with the seam and edge options, so you can see which variable you are actually changing.
Comparing an offer against your incumbent
You need the parameter list a serious offer should contain, so that a thin quotation is visible as a thin quotation.
Writing a purchase specification
You need the vocabulary — construction, rating, permeability, seam, edge, chemical envelope — in the order an engineer uses it.
What this sheet will not do
- It will not select your cloth. A datasheet is a range of what can be built. Selection needs your slurry, your machine and your failure history.
- It will not state a service life. Cloth life is duty-specific; we do not print a life figure as a product property.
- It will not present industry averages as our values. Any parameter not confirmed by the mill is marked unconfirmed in the document itself.
- It will not replace a machine check. Dimensions come from your old cloth, not from a catalogue.
Ask for the sheet, or ask the question directly
If you only need one parameter, you do not need the whole document. Tell us the machine and the slurry and an engineer will answer that parameter for your case.
