A common Webb24 feb. 2012 · When designing a new or upgraded slurry mixing system, there are several important design elements to consider. First, the viscosity of the resulting slurry or solution must not exceed the requirements of the eductor. When the viscosity is too high, a standard eductor will fail to create a vacuum, resulting in poor or no mixing.
