Perforated Plate Sieve

What is Perforated Plate Sieve?

Perforated Plate Sieve is to cut several holes from metal plate (galvanized or stainless steel) for particle sieving, the sieve holes are cut by laser to ensure precision, produced according to national standard GB/T6003.2-1997, in line with international standards ISO3310-2: 1990 R20/3, R20, R40/3 series. Orifice screen, the mesh precision is uniform and not easy to deform, mainly used for the detection of large particles and materials that have an impact on the screen, the material is brass, tin bronze, stainless steel, etc.; there are two types of round holes and square holes, the mesh The hole ranges from 0.2 to several hundred millimeters. It is often used for particle size detection and analysis of large particles or materials that affect the sieve surface. According to different materials to be tested, it can be used such as round-hole asphalt collection sieve, round-hole coal sample sieve, etc.

Perforated Plate Sieve Test Method

Tolerance for individual hole dimensions for each hole in perforated metal plate in Perforated plate sieve. Using appropriate equipment, measure the hole size with a reading accuracy of 20 μm or 1/4 of the relevant tolerance, whichever is greater.

Test 1—Visual Inspection of General Conditions

View perforated metal sheets against an evenly lit background. Screens are unacceptable if significant deviations in appearance uniformity are found, such as partial holes (4 mm and larger).

Test 2—Measurement of Hole Size and Spacing

Measure the hole size on the centerline of the square hole and the diameter of the round hole.

Minimum number of holes measured on a Perforated plate sieve with a diameter of 200 mm
Nominal sizes of holeswmm	Process for compliance and inspection	Process for calibration
125 to 22.4	All (max. 25 in larger sieves with diameter more than 200 mm)	All (max. 50 in larger sieves with diameter more than 200 mm)
20 to 4	2 × 15	2 × 30
3.55 to 2.24	2 × 20	2 × 40
2 to 1.6	2 × 25	2 × 50
1.4 to 1	2 × 40	2 × 80

On any selected area of the Perforated plate sieve, measure the size and spacing p of the holes along two straight lines and in different directions, each line having a length of at least 150 mm and including at least eight holes in each direction.

If the size of any hole is out of tolerance, the sieve is not acceptable.

If there is no minimum number of inspection holes specified on the plate, inspect all holes in the sieve.
