The History of Grinding

Copyright © 2005 by the Society for Mining, Metallurgy, and Exploration.All rights reserved. Electronic edition published 2009. During our professional careers, we placed our principal emphasis on understanding the role and use of energy in size reduction, particularly in the areas of crushing and grind­ing minerals, the use of simulation for crushing and grinding circuits […]

Eli Whitney Blake

Eli Whitney Blake was a member of a leading family of industrialists in New Haven, Con­necticut, which had a tradition of invention and entrepreneurship. The family’s main business was the manufacture of arms, but family members participated in civic affairs and assisted in planning the development and servicing of the city. Genetics may have been […]


Every revolution requires a catalyst, and it was the need to pump water from mines that sparked the revolution of steam power. By 1650, coal and tin mining were important industries in England, and water had become a serious problem in many mines that had been worked for centuries, particularly the deep tin mines in […]


In the edge mill, which had been developed in China in about 200 ad, a stone or concrete disk rotated on a stone base. The ancient edge mill is still used in many communities: In 1975 people in Antakya dried and ground their wheat in September for winter. This was done in meydans (village squares). […]

Very Small Hydrocyclones

In the early 1950s, cyclones were being used in the kaolin industry to separate the finest kaolin particles into products that could be sold at a premium. Their success gave a boost to cyclone technology and led to the design of small cyclones that could efficiently extract the very fine particles from the feed. This […]


Our colleagues—some of whom we have known for many years and some we have come to know recently through e-mail—have responded most generously to our requests for information and comments. We are grateful for all the assistance we received. We would like to extend our particular thanks to those colleagues who wrote or contributed to […]

Hans Rumpf

Because the breakage environment is so different between laboratory and plant, size reduction is not a subject that readily lends itself to the classic technique of conducting basic research and then transferring the results to large-scale operations. But Professor Dr.-Ing Hans Rumpf showed that the links between empirical and fundamental knowledge could be understood through […]
