Sieve (sieve)/standard sieve for the examination

●I crush raw materials and will use various kinds of sieves (sieve) to get the product of the necessary particle size, but I measure it, and, also, a classification is the most important to measuring the particle size constitution about the particle size standard of mixtures two kinds or more whether a product is crushed to a necessary particle size in the process most efficiently.
As for the standard sieve measuring these, materials, a line diameter, a halftone plate, the size of the sieve frame are prescribed by JIS that a thing with high precision in particular is demanded from.

※The hand sieve (450 Φ, 360 Φ, 300 Φ, 240 Φ) in the wooden frame is done, too.
※I can make an examination sieve with the halftone plate product except the mention halftone plate (standard sieve standard halftone plate).
