Particle size is directly related to grinding quality, especially surface roughness. For the same kind of abrasive particle size, the sharper the processing efficiency is higher, the more rounded the surface quality is better (the surface roughness value is smaller).In general, round particles are stronger than sharp particles. The strength of the abrasive is related to the densification of its crystal structure, that is, the ability to withstand the applied pressure without being broken when the edge of the abrasive is still quite sharp. The poor strength of the abrasive, its abrasive particle crushing fast, low cutting ability, short service life. In order to get better grinding, it is required that the abrasive particles should have sufficient strength.
Jejaring berarti jumlah lubang per inci persegi, 50 netter berarti jumlah lubang per inci persegi, dan 500 networks. Semakin besar jumlah mata penggiling, semakin banyak lubang, semakin kecil butiran penggiling, semakin halus butiran-butirannya. Filter membagi partikel penggiling menjadi ukuran yang berbeda. Masing-masing 36 inci persegi dibagi menjadi 36 yang berbentuk persegi kecil, dan 80 layar per inci persegi dibagi menjadi 80 .
Pemilihan ukuran giling berkaitan dengan kinerja dan parameter kerajinan gilingan, terutama tingkat kekasaran, kecepatan masuk, dan kedalaman pemotongan monotikus maksimum pada permukaan alat belakang penggiling.
