摘要 |
Moulding sand can be properly cooled and mixed with components such as a binder by agitating it in a vacuum in the presence of water. The vapourization of the water cools the sand. This is useful where hot sand from a casting is to be recycled. Apparatus for this can comprise a filler port 3 leading to a mixing chamber 2. The chamber 2 contains an agitator 15 and a device for spraying water 20. An annular chamber 24 contains cooling coils 27 for condensing vapour removed from the sand in chamber 2 via ports 26. <IMAGE> |
