Test Sieves is a common laboratory requirement. Sieves are used for
sieving of chemical powders, medical powders, aggregate, sand soil
and cement etc.
These sieves are manufactured as per various standards like IS, BS,
ASTM, DIN etc. In Civil Engineering it is a common practice to use
sieves for gradation and particle size determination. Manufacturers
brass frame and G.I. Frames Sieves of dia. 200mm, 300mm and
450mm. Normally brass sieves are manufactured in 200cm dia. and
frame is spun brass, The Sieve cloth used is standard SS or prosper
bronze wire mush.
The G.I. Frames sieves manufactured normally n sizes 300mm dia. or
450mm dia. have a steel perforated sheet having accurately
punched square holes.
Size Available:
4.75mm, 3.35 mm, 2.80 mm, 2.36 mm, 3.00 mm,
1.70 mm, 1.40 mm, 1.18 mm, 1.00 mm, 212 µm, 180 µm, 150 µm,
125 µm, 106 µm, 90 µm, 75 µm, 850 µm, 710 µm, 600 µm, 500 µm,
425 µm,355 µm, 300 µm, 250 µm, 63 µm, 53 µm, 45 µm, 38 µm,
32 µm, 26 µm, 22 µm. Lid and Receiver for 200 mm dia sieves, made
of brass.
NOTE:
All the aperture sizes listed under can be supplied in 100 mm
or 150 mm dia spun brass frames on special order.
