Abstract

Particulate abrasive material is supplied from a container 7 to a stream of gas in a line 1 via dispensing means including a conveyor belt 9 and a duct 6. A pressure equalizing conduit 13 extends between the interior of the container 7 and said gas supply line 1 and has its lower end facing upstream in the line 1 so that owing to the ram effect of the gas, which is throttled by a valve 3 and an orifice plate 4, the pressure in the container 7 is kept higher than that at the outlet of the duct 6. The higher pressure is also maintained around the conveyor belt 9 and at the upstream end of the duct 6 by a gas-tight housing 12. The arrangement enables small quantities of abrasive material to be metered accurately into the gas stream.
