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

The plansifter screen mesh 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,

Their property and difference are as follows,

——

——

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

—

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.

1. Stretch the plansifter screen mesh 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.

• FDA & EU food grade Polyamide and Polyester raw material, safe and clean.
• Abrasion-resistant, long service life。
• Weaving by Sulzer projectile looms and superior reed to get precise mesh opening, which is less than 5% tolerance.
• Excellent heat setting by advanced washing & heat setting machine of German origin.
• Advanced and skilled technics make the sieve screen cloth in moderate elasticity and anti-deform.
• High milling efficiency and high yield.
• Full range of series and types to meet your requirements.
• Standard width 127cm, other widths acceptable for customized.

Standard packing: poly-woven bags for overseas transportation safety, wooden crates upon request.
