Manual Mixing:

The GB Lab test sieve is always used in test particle or powder size distribution analyzer.The test sieve diameter is 200mm,300mm and 400mm,complies with GB6003.2-1997.

►GB Lab test sieve Introduce
The GB Lab test sieve is two kinds of test screen mesh,one is metal wire cloth mesh,mesh requirements GB6003.1-1997;the other is perforated plates,mesh requirements GB6003.2-1997.Mounted on a slap tyle laboratory vibrating sieve or DH-300T test sieve machine, grain size composition of various powder materials were graded.For example,model: Φ200 * 50 stainless steel precision test sieve come from my company produced, the screen is used strictly in accordance with GB6003.1-1997 standards, and selected by the microscope.  



The standard screen size as follow:
8# (2.63 mm)、10# (2.00 mm)、12# (1.70 mm)、14# (1.40 mm)、16# (1.18 mm)、18# (1.00 mm) 、20# (0.85 mm)、25# (0.71 mm)、30# (0.60 mm)、35# (0.50 mm)、40# (0.425 mm)、45# (0.355 mm)、50# (0.30 mm) 、
60# (0.25 mm)、70# (0.212 mm)、80# (0.18 mm)、100#(0.15mm)、120# (0.125 mm) 、140# (0.106 mm)、
170# (0.09 mm)、200#(0.075mm)、230#(0.063mm)、 270# (0.053 mm)、325# (0.045 mm)、400# (0.038 mm)、
500# (0.028 mm)
