I've been home roasting for a year now and it had to happen- a small piece of gravel size stone got into the grinder (a robur)
The robur hiccuped and I turned it off straight away, stone was visible in two pieces in the top of the blades- couldn't get out without removing blades. Blades look ok, and all seems to be grinding ok now- but I have that doubt in my mind if there has been some hidden damage to shaft or motor.
Anyone else have experience with this? I've given some beans away to friends who use sunbeam 0480- I imagine a stone could do big damage to one of them?
Any ideas about how well destoners work as the source of my green beans is happy for me to use his, but hasn't been an issue til now.
