The Shenyang Taige TG-3060 Constant Speed Mixers provide all the necessary functions to mix cement slurries according to API Spec 10, Section 5. The mixers can also be used to thoroughly mix other shear-sensitive dry or fluid materials. Recent detailed testing within the API has shown that the methods of mixing cement slurries will significantly effect the thickening time. The TG-3060 Mixers are designed in accordance to API Spec 10 and have constant speed operation independent of the line voltage and rate that cement is added to the mix water. Good practice indicates that the cement be added slowly over a 15 second period as specified by API Spec 10, Section 5. The TG-3060 Mixers will hold the speed constant during the 35 second period without operator attention, so wide variations in shear rate are avoided. Variations in shear rate have been found to be a major source of differences in thickening time tests when other variables are held constant. Tests within the API have also shown significant variations in thickening time as a result of worn or eroded mixer blades. Major differences in thickening time are eliminated by the use of hardened blades in the TG-3060. The hardened blades resist erosion during the mixing process and retain their original shape and pattern many times longer than standard blades normally found on regular industrial mixers. Of course, worn hardened blades will need to be replaced with new hardened blades after showing signs of erosion. The hardened blades offer two advantages when used withthe Constant Speed Mixer: Increased reproducibility when measuring thickening time to reach 100 Bearden units. More efficient utilization of mixer blades - an overall lower cost per sample mixed. Shipping DimensionsWeight and Heater Power
