The two AR mounts are inserted on the round connecting
tube. The required center distance should be positioned on
the straightening plate (parallelism), subsequently tightening
of the two collars with the required fastening torque.
The three AR mounts are inserted on the round connecting
tube, with the direction inverted center element. This so said
“boomerang”-configuration is offering on the counter-mass
trough a direction inverted flow of material, what could sim-
plify selection and screening processing
.

Dimensioning of the connecting tubes
The connecting tubes have to be provided by the customer.
For Single Rockers the wall thickness of 3 mm (up to center
distance A = 300 mm) is fully sufficient. For Double Rockers,
due to resulting shear forces, higher wall thicknesses are
required – see below-mentioned table.

The three AR mountings are inserted on the round connecting
tube (please check required material thickness by the relevant
center distance on below-mentioned table). The counter-mass
can be used as second trough with identical feeding direction.
