@Yann correct me if im wrong, but i believe this was taken out on purpose since this machine is not meant to operate with a sieve anymore compared to the version 1.0 of the Shredder PRO.(edited)

so, that being said, we should update the drawing 1000.00-0 and remove the sieve from the parts list(edited)
Yes, this is right, this shredder doesn't work with a sieve, therefore we didn't put the drawings 1400..., but we forget to remove them from the 1000.00 assembly drawings, we will do that, thank you for pointing it out !
We usually shred 2 to 3 time depending on the plastic objects, and that works for most PP machines. But if you really need a fine and precise shred because you want a smooth output out of the extruder for example, then you need another machine (a granulator or the basic shredder with a sieve works also well).

This issue should be solved with the shredder developed with Weima hopefully.
Hello, I am planning to build the SHRPRO 2 but I am blocked ! On the part SHRPRO-2 1000.04-0, from computer there is 4 holes of 16mm I suppose that it is for fixing the bearing support with the shredder box, but there is no space for a nut inside because of the shredder blades. So actually I suppose that the shredder box part SHRPRO-2 1100-(05 & 06) should it be tapped is this correct ?
yes, you have to tap the M16 holes as its indicated in the drawings:
SHPRO -2 1100.05-0
SHPRO -2 1100.06-0
SHPRO -2 1100.07-0
SHPRO -2 1100.08-0
SHPRO -2 1100.09-0
Be careful though, you need to tape the plate 1100-05 & 06 together, as well as the 1100-07, 08 & 09 together. So you have a continuous thread on the 2 plates. This was already the way to attached the bearings on the version 1.0, this new blocks have the same spacing, hole size etc...
Thank you very much ! We are actually working on these parts, we try to avoid maximum tap, turning and milling when it could be replaced because of the cost of it.
Did you tried to separate the part SHRPRO-2 1000.04-0 into 4 sheets ?
-2x10mm and 1x6mm ( for the sheets that goes around the bearing)
-1x6mm (for the sheet that goes after the bearing)
This way you could block some screw inside the sheets to fix the parts
SHRPRO-2 1000-02 & 03 without tap.
Also by doing the same hexagonal hole on the part SHRPRO-2 1100.05 & 07 the screw could fit inside the sheet and tight the SHRPRO-2 1000.04 without Tap.
This is what we suppose, but maybe there is a reason why this could be false because we did not tried yet(edited)
If you use multiple sheets for the 1000.04, you'll probably don't get the right tolerance to insert the bearing. In that case I would go back to the system used in the 1.0 : bearing blocks you can buy off the shelves. This is less resistant, but if you use the 2.0 fixed blades, it should be fine.

For the thread question, I would rather use conical head M16 bolt, and screw it from inside , with the nuts on the bearing block side. You sill need to do the conical insert for the head inside, which is more or less the same work than making a thread, but it is possible if you prefer that technique.
