I have noticed people's tendency to do that (and forgo gears entirely and just use RF transport). I am nerfing both.
what
exactly
have you done?
Is there a plan to break the extractor up into multiple blocks? On the one hand the mechanics of the device encourages the use of more extreme power solutions.
On the other hand, the way it stacks torques and speeds doesn't seem right. And it just it does too much in a single box.
Also, the grinder, which achieves 3/5 the effiency, seems unbalancedly strong as an early game ore doubling tool. Especially as it 3x rather than 2x its ore output.

Lastly, some of your devices use power-from-below. This is a problem for ... the kind of 'hardmode' I like to use - where I try not to mix mods (especially if they have overlapping purpose) - so I have only the hopper available to extract outputs.
Please consider making it an option for the extracter to auto eject outputs into adjacent inventories first before moving to the next stage.
