Although much of the basic technology of crushing, grinding, screening and magnetic separation were in use in the 19th century, and earlier, it was not until the 20th century that the modern methods used today became commonplace.

During the Annual Meeting of the American Institute of Mining Engineers, several process equipment manufacturer executives met to explore the formation of an association of top executives of process equipment companies. Shortly thereafter, the same group plus a few others determined the formation of an “official” association merited further research.

The group reconvened and reasons for an industry association emerged: 1) The problems of management to operate companies profitably were becoming more complex, and 2) Discussing these problems with peers – who also at times may be competitors – would yield mutual benefits.

A meeting attended by 17 companies during the Chemical Machinery Show in
New York City resolved the creation of the Process Equipment Manufacturers’ Association (PEMA).

The organization committee developed the Bylaws, Constitution and budget. Article XI of the Constitution provided that the organization would be in effect when seven companies formally accepted the Constitution and Bylaws and paid their initial assessment of $250. On August 5, 1960, PEMA became official when the seventh company signed up for membership.

PEMA became a registered trademark.

PEMA celebrated 50 years of service to manufacturers of process equipment.
