Flour Milling Mesh Sifting Cloth
Bolting Cloth Flour Mesh with Fine Sifting and Filter Property: A Kind of Monofilament Thread Woven Fabrics, Suitable for Flour Milling. Comparison of Different Fabrics, General Specifications Listed.
The bolting grade monofilament polyester cloth is mostly supplied cut to size to fit the flour milling sifters or filters. It is also used as fine screen printing mesh. Petter supply mill grade bolting mesh with fine sifting properties. It will never get rust with polyester materials. Petter polyester screen is woven from yarn that is extruded from heated polyester into a single strand. The extruded thread is the spun to a precise diameter. Conventional monofilament polyester screen fabric will elongate under tension: the higher the tension level, the more the thread can stretch. At excessive tension levels, the thread reaches its "plastic deformation" point, and the mesh will no longer hold tension.
Flour milling is a process of grinding and separating, done by roller-mills, sifters and purifiers. Petter offers a wide range of high-quality, sifting fabrics and bolting cloths for milling applications. Our Flour mill mesh product line is carefully adapted to the special requirements of the flour milling industry and provides optimal sifting efficiency and maximum service life.
In the early days, natural silk bolting cloth was the standard. Nowadays, synthetic fabrics have replaced silk to be used in flour milling process. The following table shows the differences between silk and synthetic fabrics.
Comparison of Polyester, Nylon and Silk Materials used for Flour Milling Mesh:

tensity strength (kg/mm2) | 41-67 | 45-75 | 36-45 |
elongation (%) | 20-35 | 15-30 | 15-25 |
resiliency (3%) | 95-100% | 90-95% | 54-55% |
temperature (celsius) | 100 | 140 | 100 |
water absorption (relative humidity 65%, 20 °C) | 3.8% | 0.4% | 11% |
resistance to corrosion | good | good | fine |
mass specific resistance (/cm.g) | 4.1 * 10e | 2 * 15e | fine |
