Brass Sieve
Test Sieve is a common laboratory requirement. Sieves are used for sieving of chemical powders, medical powders, sand, soil and cement etc.
These sieves are manufactured as per various standards like ISS., BSS, ASTM, DIN etc.
In Civil Engineering, it is a common practice to use sieves for gradation and particle size determination. ‘Contass’ manufacturers brass frame and G.I. Frame Sieves of dia 200mm, 300mm and 450mm.
Normally, bras are manufactured in 200cm dia, and the frame is spun brass, jointless. The Sieve cloth used is standard SS or phosphor bronze.
The G.I. Frames sieves, manufactured normally in sizes 300mm dia or 450mm dia, have a steel perforated sheet with punched square holes.
