Stainless Steel Lab Sieves


Stainless Steel Woven Wire Mesh Lab Screening Sieves

To avoid chemical corrosion, we recommend the use of stainless steel (ss 304, 316 and 316L) wire mesh sieves for laboratory testing and analysizing.

Stainless Steel Lab Sieves Material:  302  304  304L  316  316L stainless steel wire. Can be made according to the customers' requirement 

According to different materials and produce process, test sieves can be divided into brass mesh test sieves, woven mesh test sieves, perforated plate sieves and grid sieves. Special sieves are available, such as half height sieves, micro plate sieves, wet washing sieves, extra depth sieves, air jet sieves, grain Sieves. For instance, stainless steel half height sieve and microplate sieve with woven wire mesh in diameter 30mm to 120mm used to sieve silica from a particle size of 500 microns to 20 microns.

Laboratory test sieve is a measuring instrument, mainly used in metallurgy, abrasive, construction industries and research lab for precise classification of the minute granule materials. For example, certified sieves may be used for pharma testing. Sieves should be used with care, cleaned regularly and stored in a safe dry place.

Woven wire mesh sieves with precise opening are the most widely used test sieves for laboratory particle size analysis. Seamless frames ensure a precise fit and superior quality. They are made of the highest quality brass or stainless steel materials and are available in diameter sizes of 38, 100, 150, 200, 250, 300, 315, 350, 400 and 450 mm.

  • Steel screening mesh in stainless steel with aperture sizes 1mm - 1.5mm, is durable enough for screening slurry used in chrome alluvial wash plant.
  • Basic sieves with meshes that have holes with diameters 1mm, 2mm, 3mm and 4mm for filter ceramic particles.

The laboratory sieves are widely used in the chemical, food , pharmaceutical , building materials, metallurgy and environmental protection industry ,sewage,wastewater treatment process material testing analysis.

The Working Condition and Procedure of Laboratory Sieves:

 1, The elevation not more than: 1000 meters

2, The ambient temperature: - 5 ~ 40

3, Relative humidity is no more than 90% (20 ℃ below )

4, Ambient medium without conductive dust and corrosion and damage the insulation of the gas.(Namur except)

 The method of operation of the   laboratory sieves

1, Standard test screen to placed in a horizontal position

2, Recognized the power and nameplate conform to the requirements , and to ensure that the ground

3, The vibrating portion can not contact with other objects

4, Ensure that all bolt is lock

5, To determine the standard screen frame to be chosen according to the test materials and the corresponding standard

6, Aperture standard sieve box from small to large , from bottom to top in turn stacked on the base of the screen fram

7, Laboratory sieves   materials placed in the top box , covered with a cover of the standard sieve.Adjusting lever according to the total height of the adjustment of the standard sieve box height,then use clamp and locking nut to standard screen box positioning pressure

 8, According to the nature of the material and the feeding amount , set the running time on the timer ,Then turn on the power switch, the standard test screen began to work

 9,  Laboratory sieves  work stopped , unscrew the lock nut , remove the pressure plate , carefully removed the standard screen frame ;

10, Cut off the power
