This revolutionary design enabled pasta makers to enhance mixer efficiency
and capacity by perfectly pre-wetting each semolina particle prior to entering the main mixer.
In practice, this reduction in binder additions is not only affected by sand surface area and grain shape but also by mixer efficiency
when additions are low.
Our objective is to investigate the mixing process and to predict the mixer efficiency
of a transverse jet with the constriction of venturi.
Therefore, in evaluating mixer efficiency, properties such as segregation and aggregate grading throughout the mixture should be monitored.
Based on the concept that measuring compositional homogeneity of a mixture can provide evidence of the efficiency of the mixer, RILEM  tried to establish a classification of mixer efficiency by defining three classes of mixers: ordinary mixer, performance mixer, and high performance mixer.
Rotary valves meter the ingredients from the weigh-hopper into the mixer in a fine stream, so improving mixer efficiency
and product consistency.
studies are an easy way to determine the appropriate mixing times for each mixed sand formulation and to obtain the highest performing mixed sand.
