getting spherical and uniform substrate grains from non-uniform grains. DIY?

I was thinking of making a DIY "tumbler" and using it to process some soilmaster select charcoal or perhaps larger grained substrate. This would involve tumbling the soilmaster in a cylinder for a period of time (week) until the grains have eroded and sanded each other into more uniform spherical shapes. Granted, it would create a lot of waste dust, but, it's just for aesthetic purposes. I am not sure if there are any biological advantages to having round uniform grains.

Any thoughts or suggestions on this idea>?

The SM I use is already pretty uniform in grain size. It is certainly more uniform than most gravel or blasting grit I have used. And, given that my grains are not spherical, I suspect that tumbling them might not yield spherical grains, but just smaller irregular grains.

I think Hoppy is correct. Tumbling is not going to produce spherical grains.

no matter how you try to shape and piece of rock of any type, it will always chip the same way but in different patterns (I hope I am explaining this right). It would be possible to shape a rock of any sort into a more spherical shape, but accomplishing the sphere shape would require a different technique for each way the matter is composed. Using a tumbler of some sort, like what they use to season cheeto's with seems like a good start. Atleast you know over time each grain will recieve equal friction to all its surface area thus logically producing a more spherical shape. This is just my guess. I think its worth the experiment. If you have the equipment there is no capital to buy, so why not.

i will test it out on a small scale once my shipment of SM comes in from my local lesco.
