What is the difference between a standard sieve and a sample sieve? Which sieve is better to determine the fineness of heavy calcium carbonate?

Sampling sieve, also known as the standard sieve, test sieve, are generally called, just inside can also be divided into a number of sub-categories such as coal sieve, traditional Chinese medicine sieve, according to the sampling object is different, a little difference in the material, the owner understands it

Not sell sieve, specific do not understand too much, I also listen to others, just our factory also has a few sieve sieve heavy calcium, is the Shanghai side of the production, used for several years! Do not block the stainless steel is good, is a little expensive, hundreds of dollars a, the instructions said to use distilled water to dilute the heavy calcium and then test the rate of passage, through the fast, accurate data, residual less, do not hurt the sieve and so on benefits, but look at our inspectors basically are just take a cylinder, tap water, a connection, chopsticks with chopsticks, chopsticks, no chopsticks with the finger stir and stir and poured into the sieve, but it is a few small children often take a glass rod or something to play with!

Truly serious words, you can use the particle size meter test, laser, to get the particle size, and then according to the micron data against the corresponding mesh, but occasionally the data is not so reliable

Supplementary Answers:

One of the traditional methods is to go through the sieve. Two kinds, manual and electric. Methods, diluted with distilled water over a sieve. The proportion of the total mass of the mass passed is the rate of passage. This method is generally used to determine whether the mesh is qualified. Specific mesh determination with this method is too inefficient, not afraid of the trouble of elimination method slowly. Second, particle size meter detection. Laser equipment directly. Automatic detection of particle size, corresponding to the relative number of mesh. Intuitive, high efficiency. The only disadvantage of equipment costs are high. Generally low are about one hundred thousand.
