Generally speaking, it will be easier to be mixed if the powder is smooth and the worse the powder's fluidity (that is bigger adhesiveness), the more difficulty the powder to be mixed. Dry powder fluidity can be tested with angle α like the picture shown. If the angle αis small, it means the powder is smooth and good fluidity. (As shown in the right picture)when the angle α more than 40°,its fluidity will start getting worse. It will be difficulty to mix evenly for powder with αmore than 45°if used by ordinary 3D mixer. So some customers solve this problem by way of installing steel chain, steel ball and so on which have function of slung, hurl and grinding. However, it will increase contamination because of strike and grinding effect between chains, what's worse; it will generate static electricity which will bring serious potential safety hazard. Due to unique internal structure with helical blades of our double movement mixer, they have good functions on cutting and pressing. As a result, our machine can excellently complete mixing dry powder with high adhesiveness. |
