Abstract
PURPOSE: Wet crystals of sodium percarbonate are granulated, dried and passed through the tube of a specific inner diameter at a specific rate to produce sodium percarbonate of freeness from foaming and good wearability.
CONSTITUTION: Wet crystals of sodium percarbonate are granulated and dried. Then, 100kg of sodium percarbonate granules is passed through a tube of 100mm inner diameter every hour at a velocity of 10W15m/sec. The granules are refined in the form by friction between the tube wall and granules or granules and granules to remove odd parts in the granules with no desintegration of the granules themselves, thus producing the objective sodium percarbonate granules of improved wearability without formation of fine powder.
