National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Ventilation Requirements for Grinding, Buffing, and Polishing Operations.

PB277332

Publication Date	1974
Personal Author	Bastress, E. K.; Niedzwecki, J. M.; Nugent, A. E.
Page Count	196
Abstract	Criteria have been developed for the design and operation of ventilation systems used with industrial grinding, buffing, and polishing equipment. These criteria are based on the requirement that equipment operators not be exposed to concentrations of airborne particulate materials exceeding the threshold limit values for these materials. Ventilation criteria have been developed for each of nine classes of equipment which include most types of industrial equipment in current use. The criteria were formulated from analytical models of particle transport processes around grinding equipment and were verified by measurements of ventilation system performance. Both the analysis and the measurements have revealed the existence of an optimum ventilation condition for each type of equipment. At this condition, maximum ventilation effectiveness is achieved at minimum ventilation flow rate. Ventilation systems in current use, when operated at the optimum ventilation condition, are found generally to provide effective control of inert particulate materials.
