2.Iron-Coating on Rice Seed

2-1.Safety Instructions

◆ Please confirm “Safety Data Sheets” of materials (iron powder and calcined gypsum) and “WARNING and CAUTION” of concrete mixer.
◆ Wear protective equipment (Safety glasses, Dust-proof mask, Rubber gloves) during handling materials (iron powder and calcined gypsum) and granulation.
◆ Do not touch the moving parts directly so as not to get caught.
