For water, it is well suited. One must however be aware that other than a few rotating and rocking parts not much has happened. There are under the hopper a little closure. This even holds water in the hopper. Therefore, in advance not wrong. The feet have front and rear holes also, presumably so that the mill can not get a "large" lift.
We had tried it for sand, this had not worked, even if the sand only constitutes an approach of liquid, it had not been worked out. The sand must be very dry very fine and especially, then it might work. But what sandboxes or beaches are so?
