Refers to the abrasive particle size, particle size marker used. metal grinding disc According to the requirements of abrasive used, the use of sieving and water into the legal system selected a variety of different thickness granularity. Coarse particle size 40μm, multi-use screening method, according to their size into 25 granularity, denoted as:
Narrow range: 16/18 to 325/400 width range: 16/20 to 60/80
Each particle size range of basic grains group size ranges, each basic particle swarm is two adjacent mesh sieve to determine the nominal size. Of fine particle size of 40μm, the use concrete cutting wheels of sedimentation. Different size for different machining accuracy and roughness.
