Abstract (en)
[origin: EP0131885A2] The device is particularly suitable for the manufacture of suspension polyvinyl chloride and has an impeller stirrer with a diameter d of 0.1-0.9 times the internal diameter D of the vessel, the stirrer planes having a distance from the bottom of 0.05 to 0.15 times the diameter d at the shaft and at the end, flow surfaces essentially parallel to the stirrer axis and an essentially triangular to semicircular cross-section, with h/d = 0.1-1, the blade thickness t being 0.5 to 5 times h and the ratio of d to the radius r of the curved blades being 0 to 4. <IMAGE>
