Going through all of the stamp mills that I have recorded, I found that some of them were different and would like to share the different styles of stamp mills that I have found over the years.
There are several stamp mills that were different than the standard mills with the straight uprights, cams and stamps. The “California Improved Stamp Mill” is a good example of the variation on the standard mill. This machine used springs to increase the pressure that the stamps delivered during operations. They could use a smaller lighter stamp to create more crushing power. There were even variations in the CISM mills. The (14) stamp mills on this presentation is a very diverse rendering of stamp mill variations.
