Apparatus for coating objects with an abrasive or corrosive fluid, for example, coating the surface of chill moulds with lime soup, is disclosed. The apparatus comprises a mixing tank having an impeller for feeding the fluid to an intermediate tank. A plurality of individually directed spray nozzles are arranged to spray fluid from the intermediate tank over the surfaces of inverted chill moulds. A collecting chute and purifying basin are provided for collecting the excess fluid and returning it to the mixing tank. Air is pumped into the bottom of the intermediate tank to prevent silting of the coating fluid. |
