This page covers the 60 mesh count of flour mill plansifter sieve frame: the woven specification per ISO 3310-1 cloth / mill OEM frames, the particle size it retains, the open area it presents to flow, and the neighbouring counts to step to when the separation requires it.
60 Mesh Specification Row (ISO 3310-1 cloth / mill OEM frames)
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Frame |
|---|---|---|---|---|---|
| 60-Mesh | 0.190 | 0.233 | 233 | 30.4 | Square 740 u00d7 740 |
60 Mesh to Micron & Aperture
| Openings per inch | 60 |
|---|---|
| Aperture (opening width) | 0.23 mm |
| Micron rating | 233 µm |
| Standard wire diameter | 0.19 mm |
| Open area | 30.4 % |
Aperture = (25.4 mm ÷ mesh count) − wire diameter. The micron rating equals the aperture in micrometres; actual retention also depends on particle shape and cake formation.
Wire Diameter Options at 60 Mesh
| Option | Wire dia | Aperture | Micron | Open area | Weight (SS) |
|---|---|---|---|---|---|
| Heavy wire | 0.247 mm | 0.176 mm | 176 µm | 17.4 % | 1.88 kg/m² |
| Standard wire | 0.190 mm | 0.233 mm | 233 µm | 30.4 % | 1.12 kg/m² |
| Fine wire | 0.143 mm | 0.281 mm | 281 µm | 44.0 % | 0.63 kg/m² |
Heavier wire adds strength and abrasion life but closes the aperture; finer wire opens the aperture and raises throughput at the cost of durability. Specify mesh count AND wire diameter to fix the aperture unambiguously.
Open Area & Flow at 60 Mesh
The standard 60 mesh weave presents an open area of about 30.4%. At this count the mesh presents little flow resistance; selection is normally driven by particle retention and mechanical strength rather than pressure drop.
60 Mesh Cloth Weight
Standard 60 mesh stainless cloth weighs approximately 1.12 kg/m² (density 7.93 g/cm³ basis; brass and copper weave roughly 10% heavier, aluminum about one third). Use this figure for roll handling and freight estimation.
Typical Applications for 60 Mesh Flour Mill Plansifter Sieve Frame
60 mesh flour mill plansifter sieve frame is commonly specified for general straining and sieving, paint and coating filtration, grease filters, insect screening, grain cleaning and pre-filtration ahead of fine media.
Plain, Twill or Dutch Weave at This Rating?
Plain square weave is the standard at this count: every opening is a true square of the stated aperture, retention is absolute for hard spherical particles, and the cloth is easy to clean.
When to Step Up or Down from 60 Mesh
Move to 80 mesh when particles are passing that must be retained; drop back to 50 mesh when the element blinds too quickly or the pressure drop is excessive. In a multi-layer pack, pair this count with a coarser support mesh downstream to carry the pressure load.
What Flour Mill Plansifter Sieve Frame Does
Separating flour, semolina, middlings and bran in plansifters with tensioned sieve frames covered in stainless steel cloth matched to each mill stream.
Fitting & Care
- Re-tension or re-cover frames during planned maintenance; slack cloth loses capacity.
- Check that sieve cleaners move freely so cloth does not blind.
