Looking at the size of the donkey motor your converter is probably a 5 or maybe a 7.5KW unit. You should be able to run most things off of it.
Obviously if your going to try it, make sure you can plug it in to a sufficiant supply as if its a 7.5Kw machine it will need at least 32A.
Run the grinder first as i mentioned earlier. Dont worry about connecting the wires up as long as the earth wire from the converter is conected to the earth wire of the grinder. Check the rotation of the grinder wheels and if needed reverse the connections on two of the phase wires. This will reverse the rotation of the grinder wheels. Its important to get the phase rotation correct as otherwise you could drive machinery the wrong way round which in some coases could cause damage. A simple bench grinder is a good way of making sure this is correct.
I started off running our workshop off of a converter (7.5Kw) but outgrew it a few years ago. I had to invest in a dedicated 3phase supply which meant laying in new cables up to a distance of about 75meters.
Im sure if you decided to sell it, somebody on here would have it as they're normally quite sought after second hand.
