10/10/2018  The Vibrating screen manufacturers Bureau VSMA has combined with the Portable & Stationary Crushing Bureau PSCB to form the Crushing, Screening, & Conveying Technical Cmte CSCTC.  For information on the CSCTC please visit that group page.


The Vibrating Screen Manufacturers Bureau (VSMA) exists to promote and further the interests of manufacturers of vibrating screens and feeders in the areas of safety, engineering, production, regulations/public policy, product operator safety and other industry matters.

Product Focus

Vibrating Screen screens and feeders used in aggregates, mining and industrial processing. The group works closely with AEM's Portable Stationary Crushers Bureau, and is a technical subcommittee of AEM's Bituminous & Aggregate Equipment Bureau (BAEB).

Bureau Activities

VSMA operates a market statistics data reporting program for participating members that collects and reports monthly industry totals of shipments and dollar sales volume for each of four product types, by size, and by US and Canada state/province, Mexico, and to nations outside North America. The reports include end use applications. Participating firms receive industry totals of all firms, by month, so that no single firm's volume is disclosed.

VSMA created and now maintains a vibrating screen handbook, which promotes standardization and simplification of terminology, and classification of products. In addition, the Bureau has produced these other VSMA publications:
