Dense planting sand belt and thin planting sand belt
Densely planted sand belt is also known as closed coated sand belt, which is characterized by the abrasives close to each other, the entire surface of the substrate is covered, there is no obvious gap between the abrasives.The sand belt is mainly used for grinding which is difficult, including heavy-duty grinding and heavy-duty grinding.
Thin planting sand belt is also known as open coated sand belt, the sand belt grinding grains according to the pre-given distance between the distribution, so there is a more obvious gap between the grinding grains, according to the use of requirements, the grinding grains should generally cover the substrate surface of 50%~70%. The soft bending property of the thin planting sand belt is good. The space between the grinding grains can reduce the clogging of the grinding debris when grinding some materials.
