Title Evaluating a buffing wheel exhaust system.
Bibliographic information Dec. 1977, Vol.116, No.6, p.65-68. Illus. 5 ref.
Abstract Dust control was studied with a local exhaust ventilation system, with and without an adjustable tongue on the wheel guard, compensating wheel wear-down and thus reducing the amount of dust-laden air entrained into the room. Particle size distribution and concentration in the breathing zone were determined and total dust volume derived. Dust analyses show that exhaust alone reduced the total dust volume in the breathing zone primarily by removing a small number of the larger particles while the tongue was effective in removing a large number of smaller particles. From the standpoint of respiratory physiology, local exhaust with the tongue is more effective than local exhaust alone.
