The Vacuum Disperser with Scraper is a comprehensive product with function of dispersing, scraping, and vacuumizing, with the core technology comes from Germany. During dispersing process, scraper can rotate along the tank wall and generates a radial mixing flow. In addition, the PTFE scraper can scrape the materials off the tank wall efficiently. It is good for the materials with mid-and-high viscosity and thixotropy property. The finished products can be discharged completely and the tank are easy to clean. With vacuum closed design, together with vacuum pump or the pump group. The vacuum degree can go up to -0.098mpa(20mba), It is apply to the dispersing and mixing materials under special working condition like vacuum degassing, vacuum materials feeding, inert gases protection etc.
