Requests silence, getting more and more flushed, while ripping what's been handed in apart, perhaps (8)
I believe the answer is:
shredder
'while ripping what's been handed in apart perhaps' is the definition.
I can't tell whether this defines the answer.
'requests silence getting more and more flushed' is the wordplay.
I cannot really understand how this works, but
'silence' could be 'sh' ('sh' is said to tell someone to be silent) and 'sh' is present in the answer.
'flushed' could be 'red' (red-faced) and 'red' is located in the answer.
The remaining letters 'der' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for shredder that I've seen before include "security equipment" , "Device for destroying documents" , "Destroyer of documents" , "one destroys paper" , "Document destroyer" .)
