Application example – Admixture
A feed screw conveyor pump leads substance 1 to a nozzle adding substance 2. For different end
products it must be possible to select different mixing ratios (ratio 1 = 1:1; ratio 2 = 1:1.12; ratio 3 =
1:1.2; ratio 4 = 1:1.21). During operation it must be possible manually to make slight adjustments of the
selected mixing ratio.
