The performance of ventilation systems used for dust control during industrial grinding, buffing, and polishing (GBP) was evaluated to formulate standard design and performance criteria. Ventilation criteria for nine classes of industrial equipment were formulated from analytical models of particle transport processes around GBP equipment, and were verified by measurements of ventilation system performance. An optimum ventilation condition was found for each type of equipment. Maximum ventilation effectiveness was achieved at minimum ventilation flow rate. The authors conclude that, until further investigations can be undertaken, the ventilation system design criteria resulting from this program should be adopted as recommended practice. Additional testing of conventional and auxiliary systems, and used in abrasive processing operations are recommended.
