８０％である。By adding water to Shirasu to 1.5 times the amount, the sandy portion with heavy specific gravity is precipitated in the lower layer, and the pumice and fine particles with lower specific gravity are precipitated in the upper layer. By discharging this upper layer, only the sandy portion is taken out. In other words, by adding water, draining the upper layer, and adding water again, unsalted sand is produced by repeating the same process 4 times. Ru. The weight ratio of unsalted sand to whitebait is about 80%.
製造された無塩砂を普通砂の品質基準と比較すると下表
の様になる。A comparison of the quality standards of manufactured salt-free sand with the quality standards of ordinary sand is as shown in the table below.

を排除し、比重の重い砂質分を取シ出すことにより無塩
砂を製造する方法である。In this method, salt-free sand is produced by washing whitebait with water to remove fine particles with low specific gravity and extracting sandy components with heavy specific gravity.
