Stagger angle

For a given degree of reaction and value of or flow rate, a choice can be made of the stagger angle or setting of the blades. From the consideration of two defining equations ... 

For fixed values of R and V, a selection of a value of tt2 (corresponding to a value of stagger angle) fixes a limiting value of o. from cascade data. Thus the blade speed, u, is determined and then the energy transfer E is found. 

As the stagger angle increases, for higher values of tt2, the optimum Vg/u decreases and thus for a given value of V, the blade speed, u, must...

Another special mixing section was described by Loomans [118] of Baker Perkins in a 1967 patent application. This is shown in Figure 6.20. These are essentially double-zipped kneading disc blocks with a 90° staggering angle.
