Re: [APD] How to crush gravel?

It seems to me that crushing this gravel may not be cost effective. But I
think an efficient means of doing so would be to lay the gravel on a
3/16"-1/4" plate steel with sizeable surface area. Then rent a miniature
ashpalt roller/compactor (has vibrate function - simialar in size to a
riding lawn tractor) and roll over the gravel until it is refined to your
desired size. It may be possible to crush this gravel with a moderate sized
plate compactor but I'm not sure the weight of the machine would be
sufficient. You may also be able to take the steel plate and gravel with you
over to a local paving contractor and give them a couple bucks to roll over
it for you. Hope this helps. Chas.

Jerry Baker's question concerning sieves reminded me of what I have been 
thinking about for many months now. I have a lot of large sized gravel left 
over from when I set up my present tanks and sieved their gravel. I have a 
mixture of Onyx gravel, lava rock, and Carib Sea African cichlid gravel that

doesn't pass through 1/2 inch mesh screens. I probably have about 150 lbs. I

would really like to know how to crush it into smaller pieces. I am looking 
to achieve sizes that pass through 1/8 inch mesh screens. Any ideas?

I don't want to hit each with a hammer. That would take forever.
