The steel grit is polluted due to repeated use, and impurities are also mixed into the steel grit, which affects the continued use. Then the steel grit needs to be self-cleaned at this time.
Impurities mixed in steel sand can be divided into solid impurities and soluble salts that cannot have both.
1. Solid impurities are self-cleaned by clear air. The steel sand can be recovered by the automatic sand suction separator in the recovery cycle, which can remove most of the large impurities and more than one third of the dust, and the solid impurities are removed in the process of entering the sand storage hopper through the abrasive screening machine .
2. The soluble salt in the steel grit can be removed by regular water cleaning, and it can be used alternately between different uses of the steel grit in the cycle. In order to recycle the steel grit, we need to clean it to a certain extent at this time. Only in this way can the steel grit be used better.
