The three shafts high viscosity mixer was designed for low floating nature and high viscosity materials. The central anchor impeller equips with scraper blades for removing adhered materials from the sides and bottom of the mixing tanks. The two serrated rotating in high speeds producing kneading, twisting and dispersing effects. While in the mixing process, the two serrated impeller will produce two whirlpools and the central anchor impeller will create turbulences which make the low floating nature materials achieve high efficiency blending, dispersing and mixing effects. This mixer is suitable for viscosity 30,000-200,000cps without heating system. With optional heating system this mixer is suitable for viscosity 500,000cps. Central Anchor low speed shaft: 0-60rpm Two serrated high speed shafts: 0-1500rpm
