4 Working with the Cutting Mill Combina-
tion
All preparatory procedures such as inserting the cutting tools and sieve
cassettes and setting the gap width of the blades are given in Chapters
4.2 and 4.2 of the Operating Manual of p-19 and p-25. Refer to Chapters
4.3 to 4.6 on working with different feed funnels and suction units.
4.1 Setting up the sample splitter
The rotating metal hood of the sample splitter has 6 boreholes, which can
be closed using plastic caps.
The ratio of division can be adjusted by closing or opening the bore-
holes. The more the number of openings closed, the lesser the mill feed
reaches the fine crusher p-19 and vice versa. The user must ascertain
the correct ratio of division individually.
The RPM can be set using the turning knob on the control housing. The
RPM must be set relatively high to prevent mill feed from remaining sta-
tionary on the metal hood. It depends on the grain size and the density of
the sampling material.
