Perforated Test Sieves – High Test Precision, Strength, Durability

Perforated test sieves, available in diameter 450 mm, 400 mm, 300 mm and 75 mm with stainless steel frames and perforated stainless steel bottom, are suitable for precision testing and abrasive sorting. In addition, our test sieves products conform to ISO 3310 standard. With accurate test precision and high strength, in most of circumstances, perforated test sieves are widely applied to all kinds of laboratory sampling and particle size analysis. Because of extensive applications, our perforated test sieves also can be used in food, chemical, pharmaceutical, building, abrasive and metallurgy fields.

Note: We can provide brass perforated test sieves for improving aesthetic appearance.

Generally, perforated test sieves can be divided into four types according to hole shapes:

Three perforated test sieves with round holes have different sizes.
PTS-01: Perforated test sieves with round holes can be used in metallurgy, abrasive, construction and research lab fields.
Five perforated test sieves with square holes have different sizes.
PTS-02: Perforated test sieves with square holes can be used as grain screening in food making field.
The picture shows a perforated test sieve with slotted holes.
PTS-03: Perforated test sieves with slotted holes can meet your requirements of accurate test precision.
The picture shows a perforated test sieve with oval and slotted holes.
PTS-04: Perforated test sieves with oval and slotted holes can increase area and speed of solid screening.

Perforated test sieves features

  • Accurate test precision.
  • High dirt holding capacity and flow rate.
  • Excellent resistance to alkali, acid, high temperature and wearing.
  • High strength and durability.
  • Low maintenance.
Many perforated test sieves are packaged well by plastic film and then put them into wooden cases.
PTS-05: Plastic film package can protect rain or water. Wooden cases package can protect external impact and damage.

Perforated test sieves package

As a professional factory, we usually take requirements of most of customers into consideration. Therefore, for security during transportation, we adopt the most exquisite and secure package way:

  1. In the beginning, we use plastic film to package perforated test sieves into a small part.
  2. And then, we put two small parts into a wooden case.
  3. Finally, we transport these wooden cases which loaded with perforated test sieves securely to meet our customers' requirements.

Perforated test sieves applications

Perforated test sieves are usually applied to solid screening. In most of circumstances, perforated test sieves are widely used in all kinds of laboratory sampling and particle size analysis. Because of extensive applications, our perforated test sieves also can be used in food, chemical, pharmaceutical, constructive, abrasive and metallurgy fields.
