JJSY30×8 round powder inspection sieve (new national standard type) is a powder fineness inspection sieve independently developed by our company according to the new national standard GB/T5507-2008 "Grain and Oil Inspection Powder Coarseness Determination". The principle is that the samples are sieved on sieves of different specifications to achieve different particle separation. Calculate the thickness of the powdered grains according to the residue on the sieve. In terms of structure, the worm gear pair with low center of gravity and high precision is used for variable speed transmission, and the eccentric link mechanism is used for plane rotation. Reliable and more convenient to operate. Electronic timing control, high timing accuracy.
