When it comes to industrial screening, the real performance of a vibro sifter doesn’t depend on the motor or the frame—it all comes down to one key component:
The Mesh Sieve.
Across industries in Pakistan—including pharmaceuticals in Lahore, food mills in Faisalabad, chemical plants in Karachi, and cosmetic manufacturers in Sialkot—production teams often face issues like slow screening, contamination, inconsistent material sizes, or machine choking.
And most of the time, the actual problem is:
A low-quality or incorrectly selected Vibro Sifter Mesh Sieve.
Choosing the right mesh sieve is the backbone of ensuring precision and efficiency. In this blog, we’ll explore mesh types, materials, applications, and expert selection tips.
What Are Vibro Sifter Mesh Sieves?
Vibro Sifter Mesh Sieves are replaceable stainless-steel mesh screens used inside vibro sifters to separate materials based on particle size. These sieves determine:
- Filtration accuracy
- Material purity
- Processing speed
- Overall machine output
At Kosmo Engineering, every mesh sieve is designed for:
- High filtration precision
- Consistent mesh opening accuracy
- Food-grade and pharma-grade safety
- Long-lasting durability
This makes them suitable for both local and industrial-scale manufacturing across all cities of Pakistan.
Why Mesh Sieves Are Critical
Even a premium vibro sifter fails without a reliable mesh. A low-quality or damaged sieve can cause:
- Poor separation
- Contamination
- Screen tearing
- Production delays
- Material wastage
A high-quality mesh sieve enhances:
- Uniform particle separation
- Faster throughput
- Machine lifespan
- Product hygiene and consistency
Types of Vibro Sifter Mesh Sieves
Below are the most widely used types in Pakistan:
1. SS and MS Woven Wire Net (Wire Netting)
It is woven exactly like fabric, but with metal wires. Each wire crosses over and under another wire, creating a flexible yet strong screening surface.
Key Features of Wire Net / Woven Net:
- Made from stainless steel SS304 or SS316, or MS wire
- Available in different grades from 10 mesh to 400 mesh
- Ideal for fine to ultra-fine powder screening
- Commonly used for spices, chemicals, flour, herbal powders, and pharmaceutical materials
2. Perforated SS and MS Metal Sieve (Mesh Sheet)
Unlike woven net, mesh sheets are perforated, meaning they are made from a solid metal sheet with holes mechanically punched into it.
Key Features of Perforated Mesh Sheet:
- Holes can be round, square, or slotted
- Perfect for coarse screening
- Best for granules, grains, pellets, plastics, fertilizers, and food ingredients
- Available in various hole sizes depending on material flow
3. Ultrasonic Mesh Sieves
- Prevent mesh choking
- Ideal for fine & sticky powders
4. Magnetic & Easy-Clean Mesh Sieves
- Used in food and pharmaceutical environments
- Reduces contamination risk
Common Mesh Numbers Used in Pakistan
Mesh size varies by industry requirements:
| Industry | Common Mesh Sizes |
| Pharmaceuticals | 180–300 mesh |
| Spices & Food | 20–60 mesh |
| Chemicals | 40–150 mesh |
| Flour Mills | 24–44 mesh |
| Plastic Granules | 16–40 mesh |
| Cosmetics | 80–200 mesh |
Kosmo Engineering provides all mesh numbers with custom diameters for any vibro sifter.

How to Select the Right Mesh Sieve?
1. Know Your Material Behavior
- Sticky?
- Free-flowing?
- Hygroscopic?
- Fine or coarse?
2. Choose a Suitable Mesh Number
- Fine materials → high mesh
- Coarse materials → low mesh
3. Select the Material Grade
- SS316 for pharma and sensitive powders
- SS304 for food and general materials
4. Consider Ultrasonic Mesh for Fine Powder
Especially below 200 mesh.
5. Check Rim Quality & Welding
Poor welding leads to leakage and short lifespan.

FAQs
Q1: What is a vibro sifter mesh sieve?
A: It’s a replaceable stainless-steel screen used inside vibro sifters to separate materials by particle size.
Q2: Which mesh material is best for food and pharma?
A: SS316 is preferred for pharma and corrosive environments; SS304 is commonly used for general food applications.
Q3: How do I choose the correct mesh number?
A: Base it on particle size: finer powders need higher mesh numbers; coarse materials need lower mesh numbers. Test a sample if unsure.
Q4: Can ultrasonic sieves prevent clogging?
A: Yes — ultrasonic mesh systems reduce blocking on very fine or sticky powders and improve throughput.
Q5: Do you supply custom sizes and rim types?
A: Yes — Kosmo Engineering offers custom diameters, rim designs, and welded frames to fit all major sifter brands.
Q6: Are mesh sieves available across Pakistan?
A: Yes — we manufacture and deliver mesh sieves and provide installation/support nationwide, including Karachi, Lahore, Islamabad, Faisalabad, Multan, and other industrial cities.
