Market Grade sieves use thicker wire than other commercial grades, and so they are commonly used for applications where mesh strength (and therefore screen life) is important. Mill Grade sieves use a thinner wire diameter, which provide more open area for a given mesh size.

WhatsApp: +86 18203695377The capacity, or throughput, of a ball mill is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind. Establishing a commercial liberation size is critical when designing and engineering your grinding circuit.

WhatsApp: +86 18203695377To accelerate the math or calculation you can use the shortened formula: D m <= Km * d^ Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. These formulas are applicable to the case of feeding a mill with only singlesized balls and not a mixture without consideration for ball wear.
WhatsApp: +86 18203695377The fineness of any sieve or screen depends upon the width of the wire used. The wire used in 10 mesh sieve will be thicker than the wire used in 60 mesh sieve. A thick wire can't make a fine sieve and a thin wire can't make a thick sieve. Fine sieves above 400 mesh, the particle size is described in microns.
