• How to choose the appropriate sieve based on the material?

  Answer: It needs to be judged based on two core factors:
  Material characteristics: Choose polyurethane mesh for wet/viscous materials (such as coal slurry and clay); For corrosive materials (such as acidic and alkaline chemical raw materials), choose 316L stainless steel mesh or polypropylene (PP) plastic mesh.
  Particle size: fine particles (0.02-2mm) suitable for metal woven mesh; Medium coarse particles (2-50mm) are selected with perforated sieve plates
  Industry standard: The food/pharmaceutical industry must comply with FDA/GMP standards, with priority given to 304 stainless steel mesh or food grade PP mesh; The mining industry focuses on wear resistance and can choose polyurethane mesh or manganese steel woven mesh.

• What is the appropriate size of the sieve for

  Grading (separating particles by size): The sieve aperture should be slightly larger than the target particle size. For example, to grade 1mm quartz sand, it is recommended to choose a 1.2mm metal woven mesh to ensure smooth sieving of the target particles.
  Filtering (removing impurities): The sieve aperture should be slightly smaller than the size of the impurities. For example, to filter impurities of 0.5mm in liquid, it is recommended to choose a 0.4mm sieve, which can effectively intercept impurities.

• Can your screen mesh be compatible with other brands of lightweight vibrating screens?

  Answer: Sure. We offer both standard size screens (suitable for most mainstream brands of lightweight vibrating screens) and customized screens (tailored according to the size parameters of your equipment: diameter, side length, installation hole position, etc.). Just provide the brand/model or technical drawings of your vibrating screen, and we can ensure that the screen mesh is fully compatible.

• Does your sieve comply with international standards for the food/pharmaceutical industry?

  It fully complies. Our food/pharmaceutical grade sieves are certified by globally authoritative standards: stainless steel sieve (304/316L): compliant with EU EC certification, smooth surface without burrs, easy to clean, and no hygiene dead corners; PP/polytetrafluoroethylene (PTFE) plastic sieve: certified as food grade, non-toxic and odorless, can directly contact food/drugs. If you need relevant certification reports, we can provide them at any time.

• What is the difference between 304 and 316L stainless steel mesh screens? Which one should I choose?

  The core differences and selection suggestions between the two materials are as follows: 304 stainless steel mesh, capable of withstanding weak acids and bases, suitable for ordinary food processing and dry powder materials (such as flour and spices). More cost-effective.
  316L stainless steel mesh can withstand strong acids, chlorine gas, seawater, etc. It is suitable for the chemical industry, marine engineering, and pharmaceutical industry (acidic material treatment), but has a higher cost-effectiveness in harsh environments.
  If your production process involves seawater, chlorine gas, or strong acids, 316L must be selected; if only ordinary dry materials are processed, 304 can balance performance and cost.

• Do your plastic/rubber screens withstand high temperatures?

  The high temperature resistance of different materials varies, as follows:
  Plastic mesh: PP mesh (up to 80 ℃), nylon mesh (up to 120 ℃), PTFE mesh (up to 260 ℃), suitable for high-temperature screening scenarios such as plastic particles.

• What is the reason why my sieve is prone to clogging? How to solve it?

  The common reasons for hole blockage and corresponding solutions are as follows:
  Material moisture/high viscosity: Replace with polyurethane screen or install ultrasonic device on the vibrating screen.
  The sieve aperture is too small: On the premise of meeting the filtration requirements, replace the sieve with a slightly larger aperture (such as changing from 0.5mm to 0.6mm).
  Improper installation: To ensure even tension of the screen mesh (loose screen mesh can easily cause material accumulation), we can use our matching installation buckle to enhance the tension effect.

• What is the average lifespan of your sieve mesh? How to extend lifespan?

  Under normal use, the lifespan of different materials of screen mesh is as follows: 304 stainless steel woven mesh: 3-6 months; Polyurethane mesh: 12-24 months. It needs to be determined based on your actual usage situation.
  Methods to extend the lifespan of the sieve:
  -Clean promptly after each use (using a soft bristled brush or high-pressure air gun to avoid scratching the surface of the sieve with sharp tools);
  -Avoid overloading operation (strictly follow the maximum load requirements of the vibrating screen);
  -Check the installation components for looseness every month, tighten them in a timely manner, and reduce the friction loss of the screen mesh.

• Can the size, hole shape, and material of the sieve be customized? What information is required?

  Supports full dimensional customization. You need to provide the following 4 types of information:
  2. Screen size: For circular screens, the diameter should be provided, while for square/rectangular screens, the length x width should be provided, and the position and size of the installation holes should be indicated;
  3. Hole shape and aperture: Clearly define the hole shape (circular, square, rectangular, or special shape) and aperture/spacing;
  4. Material requirements: For example, used for screening 5mm pharmaceutical powder;
  5. Application scenarios: such as "mining sand and gravel screening" and "food grade white sugar grading".
  Customized delivery time: 7-15 days (depending on the complexity of customization), design drawings will be provided for your confirmation before production.

• What should be done if the sieve is damaged during international transportation or if it is found to be incompatible with the equipment upon receipt?

  We provide 100% cross-border after-sales support, and the specific solution is as follows:
  1. Transportation damage: Within 48 hours after receiving the goods, provide photos/videos of the damaged package and screen mesh. We will resend them free of charge and bear the cost of secondary transportation. Specific details will be negotiated based on your actual situation.;
  2. Size mismatch: Please provide the actual size and order number of your device, and we will produce a new suitable screen for free. You only need to return the mismatched screen, and we will bear the return shipping cost or directly send a new one. Specific details need to be negotiated based on the actual situation.
  We adopt reinforced packaging (plastic/metal screen is packed in cardboard box+foam protection, and large perforated screen plate is packed in wooden box) to minimize transportation loss.
