摘要

The device has a metal block assembly (12) with three stage levels (13-15) fixed and connected in a successive manner. The level (13) incorporates vibrating micro-motors (8) around a tank (1) to produce a micro-vibration on the tank. The level (14) has a conical mixing chamber (9) receiving air jets via holes and including a suction hole connected to a venturi suction system of the level (15). The level (15) has a mixing zone to mix an abrasive powder and compressed air, and to supply the mixture to a pneumatic cleaning tool via an outlet duct.
