Fine Compost shredder - does it exist or have I invented it?
« on: March 28, 2017, 09:20:21 AM »
I have taken to making my own leaf mould but what I end up with is still quite coarse with some leaves and the central spine of the leaf still intact even after two years.  So I am wondering if there is something I can use to chop it up more finely?  I have a shredder with a 'corskscrew' blade which is fine for small branches but this material would pass straight through that.  What I would like is something that chops more finely with a wide and low entry point that can be loaded by the spade full.  I suppose it might need to incorporate a sieve to ensure that anything too large for the cutters does not get in.  Does such a thing exist or have I just invented a new garden implement?

What you need is a big version of the Fritsch mills we use for preparing soil and veg samples for lab analysis. It won't be cheap though....

Would this sort of thing help?

Thank you, Palustris; I had already discovered and ordered one of those between posing my question and reading your reply - so I will know in due course whether it helps.  But long narrow objects like the spine of a leaf will pass through a sieve so ideally I still need something that will chop them up.  The cutting mill suggested by Darren might do that job but I need a cheaper and more cheerful equivalent.

Our daughter used one of those machines to which I linked. The compost she created was as good and fine as anything I have seen. Much of the start material was leaf mould like yours and it did seem to break up the ribs.

I purchased exactly the same rotary sieve suggested by Palustris (it has gone up in price since).  I put it to first use last weekend and it really did produce the most wonderful fine compost from starting material with lots of coarser bits.  I am very pleased with it.  After a while, I worked out that I could use two stout canes to position the sieve over a spare plastic dustbin, just above the top.  This caused the sieved material to fall into the bin and meant that I could fill the bin to capacity.  It doesn't require huge physical strength to turn the handle but the continued effort gets a little tiring so I would not want to fill more than one bin a day.

Very pleased it worked for you. Price of these things always seems to be rather flexible.
