Hey Everybody Spiral Wheel question??

[Steve the Greek]

Well Last week got my hands on a nice rock crusher
and just received my 13inch Gold spiral wheel.
As I will crushing quartz what size mesh should I be using for feeding the Spiral wheel.
Any suggestions would be greatly appreciated as I'm sure I would feed it with too larger Quartz pieces.
Should it all be power form.
Thanks in advance
Steve :Y:
