What is the fastest you have ever grinded graalats in an hour?

I got 27500 gralats in 5 minutes.

I think that the most effective way to grind is pizza making unless you have your drill level 80+, top miners get tones of money.

Yeah, but takes time to enter all the rocks into the grinders (thankfully after some levels, you can enter 5 rocks at a time rather 3, I think its 5 at least lol)
