Abstract |
The initial phase of this study involved the measurement of air flow and dust concentrations in industrial environments for ten portable machines (disc sanders or grinders, belt sander, bevelling machine, cut-off wheel, routing machine, vibrating sander). In the following phase, twelve machines available on the French market (2 grinders and 10 sanders) were bench tested under several machining conditions. The main parameters were either calculated or measured: suction rate, mean concentration in booth, exhaust efficiency, mass flow rate (material removed, aerosols), size distribution for various particles. Both sets of measurements showed that integrated exhaust systems induce a good reduction of the dust level. In an industrial environment, under uncontrolled conditions, it reached 70%. On the bench the grinders' results ranged from 75 to 92%, depending on various parameters (mainly the kind of exhaust device and the suction rate). The exhaust device of grinders lead to a nearly 100% reduction of the dust level with low suction rates. |
