Flour Mill Mesh for Plansifter Screen | Nylon & Polyester Sifter Bolting Cloth

The flour mill mesh is specially designed fabrics for plansifter which for classifying the milled product in the milling industry. It’s a sifter bolting cloth weaving by FDA & EU food grade Nylon or Polyester, monofilament or double-filament yarn in precision micron apertures.

The flour mill mesh cloth plays a crucial role in the milling industry, which decides the balanced and stable flour quality.

Nowadays, the Nylon (PA) and Polyester (PET) mill mesh fabrics are most widely used instead of natural silk mesh, due to their integrative performance, please see their characters as below,

plansifters mill screen cloth

1. Natural silk flour mill mesh, made out by 100% multi-strand natural silk yarns, its merits good elasticity, anti-lax, anti-deform, good hygroscopicity, anti-static. However, it’s poor wear-resistant and easy to fluff.

2. The Nylon (PA) flour mill bolting cloth are weaving by nylon monofilament yarn, it’s wear-resistant, good hygroscopicity than Polyester, high strength, long service life, the best integrative performance at the moment.

3. Polyester (PET) sieve cloth is in performance of high strength, anti-deform, stable & constant tension, Resistant to temperature changes, but its wear resistance and anti-static property are not as good as Nylon.

Their property and difference are as follows,

Bonfilt’s flour sifting mesh fabric category

plansifters

The hardness of different wheat and grains, the different constitution of the endosperm requires to choose the suitable sieve cloth. According to the weave pattern, thread yarn and mesh opening micron size, there are PA-GG (Grit Gauze) series, PA- Milling Forte (MF),  PA-XX (Taffeta) series, PA-XXX (HD) series, PET-GG (Grit Gauze) series to meet different milling and purifying requirements. Bonfilt is supplying the full range of mill mesh fabrics.

Usually, the different series are using in different area.

PA-GG

——

PA-GG (Grit Gauze) series, plain weave, has relative thicker yarn & bigger mesh opening, commonly used in coarse sieving, can be replacement of Stainless steel mesh.

PA-XX

——

PA-XX series mill mesh is monofilament & double filament in turns in warp yarns, it’s dimensionally stable, has large effective sieving area, roughened surface, to get better automatic grading performance. It’s the most applied in the milling plants.

PA-XXX

——

PA-XXX (HD) series sifter cloth is weaving in plain weave and thicker thread yarn, which call enhancement type, it has the better abrasion resistance and long lifetime.

PET GG

——

The PET (Polyester) – GG (Grit Gauze) series sieve mesh is mainly used in purifier covers on flour cleaning machine, who classification and separating the bran, glutenous endosperm, and pure endosperm.

How to choose the optimal sieve screen cloth for your flour mills? There are 6 technical points for the mill mesh fabrics:

1. Mesh opening size: It refers to the distance between the two adjacent yarns, the critical parameter of a mill screen fabric, which decide the final flour fineness and quality.

Sifters Mesh opening Sieve screen fabric
Coarse >1200-900um PET & PA grit gauze
Medium >1000-212um Polyamide grit gauze
Fine >300-90um Polyamide flour sieve

2. Wear-resistant property: It determines the service life of the milling screen. Nylon has the best wear resistance in all the materials, polyester is only 70% of Nylon, and natural silk is the worst. In the same material, the thicker of the yarn diameter, the better wear resistance.

3. Elongation: The natural silk mesh fabrics have the lowest elongation than polyester and nylon. However, the heat setting treatment makes polyester and nylon mill mesh anti-deform and elongation as small as possible, which is similar to silk.

4. Antistatic property: All flour sieve cloth have to be antistatic. Due to the contact and friction between fiber and fiber, fiber and material will cause static electricity, and the fine flour particles are easy to be captured by the charge and blinding the sifter screen. Nylon mesh has better antistatic performance due to its high hygroscopicity.

5. Width: High-yield & high-square plansifters improve milling efficiency and productivity. You have to choose the optimal width according to the end user’s plansifter and purifiers. Bonfilt has 1.10m, 1.27m, 1.36m, 1.45m, etc to meet your requirements.

6. Effective sieving area: It refers to the percentage of the opening area in the unit screen. It‘s related to the size of the yarn diameter and the weaving pattern.

Main points during use

1. Stretch the mill screen cloth in moderate tension, too loose will get bad sieving performance, although the too tight screen will get worse outcome as well.

2. Too tight mill screen will make:

  • Mesh opening largen and deform.
  • Over the screen, elongation limited and shorten the lifetime.
  • Reduce the elasticity of the sieve screen, unable to spring the cleaners to clean the screen, block the holes.
  • Cause deformation of the screen frame, especially for screen size over 7 4 0mm × 7 40 mm, and leaking.

3. The mill screen fabrics should be stretched step by step to ensure the screen mesh stretched balanced and evenly.
