phase motor.
6.1 Comminution of material to be crushed
6.1.1 Setting the gap width
The gap width between the crushing plates determines the mean particle
feed size of the crushed material. The crank can be used to set the gap in
increments of approx. 1 to 15 mm. (at the lowest position, the gap is
smallest - see image)
To change the gap width, pull out the knurled knob of the crank and set
the crank to the desired position. Let the knob snap into place properly;
this fastens the crushing plate.
Materials which are difficult to crush (e.g. alloys) should
be pre-crushed using a larger gap width in a first pass.
Then, for the second pass, set the appropriate gap
width for the desired fineness.
If no practical data is available on the crushing proper-
ties of the sample material, it is recommended to care-
fully crush part of the sample material in a first pass.
