I have a question about the quote, the shipping cost is not clear to me, the 950 dollars correspond to the shipment of the two teams that are shown in the quote or correspond to just one? I mean, if I decide to buy a single equipment, in this case the Gravity Separator 5XZ-3, how much would the shipment of this equipment cost?The last consultation, could you do an experimental test to verify that the equipment works with the mineral that I have mentioned (Zeolite)?
