While I have not used this specific make or model I hace used a
'crushing' type of shredder before.

What does a "crushing" shredder do, and what does a shredder which is
not a crushing shredder do?

I have seen three types if shredder.

What I would call Rotary.
Material feeds into a pair of blades, the material and blades being
perpendicular to each other.

Screw
Seems to be favoured by Bosch. Material feeds into the threads of a large
screw somewhat reminiscent of a Leonardo Da Vinci invention.

Crushing

The key to this type is oval rotating drum. The drum has blades positioned
to cut the material and the oval squeezes or crushes the materal before it
is left to drop out into the collecting tray. The crushing effect is better
for thicker woody items.

While the rotary types whizz away with the blades a-blur, the crush types
just chunk, chunk, chunk away. The result being much less noise and an
ability to deal with bigger stuff.

I chunked up an old broom handle, but I would not try that with a rotary
shredder.

Hope that helps
