Relating to powder spray coating |
摘要 |
A powder spray apparatus is described including a powder booth with a scraper bar which reciprocates across the floor thereof to collect deposited overspray powder and supply it to intakes located at each end wall. The intakes are connected by a feed channel to one or more cyclone separators. An exhaust duct may also be provided for air-borne overspray powder which preferably forms part of the feed channel. Powder recovered from the cyclone separators may be passed to a common collection hopper by use of a venturi pump which transfers the powder from each separator to the hopper via a sieve located in a ventilated enclosure above the hopper.
